The Dangers of UV Rays to Health

Before we start learning the difference between UVA and UVB rays, it’s good to understand how serious and dangerous UV rays are! This awareness can help us be more regular and consistent in maintaining our skin health. Apart from premature aging, cancer, and skin damage, UV rays are also responsible for health problems such as:

• Cataracts: UV exposure, especially over long periods of time, increases the risk of developing cataracts. Cataract is a condition where the lens of the eye becomes cloudy, obscuring one’s vision.

• Retinal Damage: It can also damage the retina, the layer inside the eye that is responsible for vision. The effect will be vision problems and impairment.

• Skin Immunosuppression: This makes the skin more susceptible to infection, inflammation, and other skin health problems. A weakened skin immune system can worsen skin conditions such as dermatitis, eczema, or skin infections.

• Systemic Effects: Long-term exposure to UV rays can also have an impact on the immune system as a whole. We could be more susceptible to diseases!

Therefore, not only the skin, UV rays can produce a negative impact on the health of the body. Can you see how important it is for us to be aware of this issue? Let’s learn the difference and the steps we need to take to protect ourselves!

What is the Difference between UVA & UVB Rays

There are specific differences between these two UV rays. First, we can look at the wavelength. The longer the wavelength of UV light, the higher the penetration rate. UVA rays have a wavelength of about 320-400 nanometers, while UVB rays have a wavelength of about 280-320 nanometers. What does this mean?

This relates to the penetration rate of UV rays. UVA rays are able to penetrate deeper into the skin layers, including the dermis, while UVB tends to attack the upper layers of the skin, namely the epidermis. Not just skin, UVA rays can still penetrate glass and even clothes!

Next, the difference in intensity. UVB has a higher intensity than UVA, usually more pronounced during midday (varies depending on the time of day). While UVA has a lower intensity but is constant and stable.

So, that’s more or less the basic difference between the two types of UV rays. The impact on the skin is obviously different too!

The Impact of UVA and UVB Rays on

The “A” in UVA stands for Aging. This means that UVA rays have more impact on premature aging cases for the skin. Whereas, the “B” in UVB refers to Burn which means to burn. That is the first difference between the two in their impact on our skin.

UVA has the potential to cause problems such as:

• Skin Aging: UVA rays can damage elastin and collagen fibers in the skin, leading to premature aging. This can result in wrinkles, decreased skin elasticity and dullness.
• Causes of Sunspots: Repeated exposure to UVA rays can cause sunspots or hyperpigmentation that appear as dark spots on the skin.

Instead, UVB has the potential to cause problems such as:

• Sunburn & Skin Damage: Overexposure to UVB rays can cause sunburn. This happens because UVB stimulates the skin to produce melanin as a protective response, resulting in redness and burning.

In addition, these two UV rays also contribute to the risk of skin cancer. Very scary isn’t it? Then what are the ways we can do to keep our skin protected?

Choose the Right Sunscreen

Of course, the main thing we can do is use sunscreen! That being said, don’t forget to also use protective gear such as sunglasses, hats, or long-sleeved clothes and take shelter especially when the sun is at its hottest (between 10 am – 4 pm).

But what sunscreen should we choose? It depends on your skin type and how long and intense your sun exposure is. For those of you with light and pale color tones, we recommend choosing a sunscreen with SPF 30 – 50+ (high protection), whereas if our skin tends to be darker then even a lower SPF is still safe. 

In addition to SPF, the sunscreen you choose should be labeled PA+ (referring to UVA protection). The higher the protection, the more “+” signs there will be (for example: PA+, PA++, PA+++, and so on).

Other tips for choosing based on environmental conditions include:

• SPF 15 / PA+ for indoor activities
• SPF 15-30 / PA++ for outdoor activities
• SPF 30-50+ / PA +++ for frequent and prolonged exposure to the sun

We just need to adjust it to our skin needs, isn’t it easy? If there are certain skin conditions and problems, Sereni-Trees should consult a professional first so you don’t make the wrong choice!

Which is more dangerous, UVA or UVB rays?

While both have a significant impact on the skin, it turns out that UVA rays are far more harmful than UVB rays! With their ability to penetrate clouds, glass, and even deep layers of skin, imagine what could happen if we continue to be exposed without protection?

UVB damage may be visible immediately, but generally only on the upper skin layers such as burns. This is why people are more aware of the dangers of UVB. But the impact of UVA is more long-term/not immediately visible. Cases can start from skin discoloration, continue to photo aging (all kinds of wrinkles such as fine wrinkles and sagging), and finally, skin cancer. 

In conclusion, we should still give our skin maximum protection against both UV rays every day. No matter where we are, inside or outside, sunny or cloudy, UV rays can still cause damage to our skin! Instead of regretting it later, let’s start being more aware of the dangers of UV rays. Don’t forget to maximize your skin protection with Serenitree’s bodycare range!

That way, we can take advantage of the benefits of UV rays and minimize the side effects through prevention.

Benefits of UV Light for the Body

Ultraviolet (UV) light can provide significant benefits to all organisms on earth, without exception, humans. One of the main benefits is that it increases the production of vitamin D. When the skin is exposed to UVB light, a chemical reaction in the body produces pre-vitamin D, which is then converted into vitamin D. This vitamin has an important role in maintaining bone health, regulating the immune system, and supporting muscle function. When we are deficient in this vitamin, health problems such as osteoporosis, rickets, and an increased risk of autoimmune diseases can occur. How scary!

In addition, UV exposure can also improve mood and help reduce the risk of depression. Naturally, sunlight can stimulate the production of serotonin (the happiness hormone) in the brain. Increased serotonin levels can improve mood and provide a feeling of well-being. So if you’re feeling moody or uninspired at any point in time, try to get some sun at the right time! 

Last but not least, it turns out that regular UV exposure can improve the quality of our sleep! This is because of the relationship between sun exposure, especially in the morning, and the body’s circadian regulation. UV exposure can regulate the production of melatonin, a hormone that plays a role in regulating the sleep cycle. Therefore, problems such as insomnia can be reduced with frequent exposure to sunlight properly and correctly.

These are just 3 major benefits out of a thousand, Sereni-Trees! Even some illnesses can be quickly cured by regularly sunbathing in the morning. That’s how powerful the positive effects of UV rays are!

The dangers of UV rays for unprotected skin

Despite their benefits, UV rays also carry serious risks to skin health. Overexposure and unprotection can negatively dangers the skin! Some of the problems we can experience include:

• Skin Damage and Premature Aging: UV rays can damage collagen and elastin in the skin. This can lead to premature aging, such as the appearance of wrinkles and fine lines on the skin.

• Skin Cancer: Although not always and definitely, UV exposure increases the risk of developing skin cancer. UVB rays can damage the DNA in skin cells, triggering the growth of abnormal cells. This can eventually lead to the development of skin cancers, including basal cell carcinoma and squamous cell carcinoma!

• Sunburn: One of the direct effects is sunburn, the symptoms of which include skin redness, swelling, and pain. Repeated sunburns can increase your risk of developing skin cancer!

• Hyperpigmentation and Skin Blemishes: UV exposure can stimulate the production of melanin pigment. This can lead to hyperpigmentation and dark spots on the skin. As a result, we may experience uneven discoloration and dullness of the skin.

• Predisposing Skin Diseases: Certain skin conditions such as atopic dermatitis and psoriasis can be aggravated by overexposure to UV rays. Sufferers of these skin diseases may experience flare-ups or exacerbations, so it’s best to stay safe!

It turns out that behind the myriad of benefits, there are also various dangers lurking. But rest assured, we can neutralize these negative effects with proper and consistent protection!

Fortify your skin with the right protection

We can experience the positive benefits of the sun with the right habits and protection! The first and foremost step is to always apply sunscreen (minimum SPF 30) every day! Make sure to apply it evenly on all exposed skin, even on cloudy days. If you are frequently exposed to the sun or live in a very hot area, add extra protection such as hats and jackets. Additional tips: Wear sunglasses as UV rays can potentially damage your eyes).

Well, the next thing that is no less important, we must also strengthen skin protection with regular care both from outside and inside the body. It’s simple really, just pay attention to a balanced diet and regularly cleanse and moisturize the body with the right bodycare.

It’s also important to know when to avoid UV exposure! Direct sunlight can be harmful during the most intense hours, which are between 10am and 4pm. This is the period when UVB rays tend to be stronger. Therefore, if you want to sunbathe, it should be around 10 to 11 am, or in the afternoon, after 4 pm (10-20 minutes is enough).

In the last step, we can look up the UV index for our area, Sereni-Trees! This index measures the intensity of UV rays and provides an assessment of the potential risk of UV exposure to the skin and eyes. An index of 0-2 is considered low, 3-5 moderate, 6-7 high, 8-10 very high, and 11+ extreme. The higher the index, the higher the risk of UV exposure, so we must increase our protective measures!

In conclusion, an in-depth understanding of the benefits and dangers of UV rays on the skin helps us take appropriate preventive measures. We know how much UV rays are beneficial to our bodies, as well as the dangers. To give our skin the best, we must involve consistency, skincare product selection and balanced living habits. Applying sunscreen once or twice is not enough to protect our skin! 

Don’t forget to educate each other so that we can be healthy together, remember, sharing is caring!

The post What are the benefits and dangers of UV rays on our skin? appeared first on Serenitree Indonesia.

On this occasion, Serenitree will explain why sunscreen is so important, its benefits, and some do’s and don’ts tips that you need to know about using sunscreen. Using the wrong sunscreen can also cause skin problems. So, let’s take a look together!

Why is sunscreen so important?

Sunlight itself is good for your health because it triggers the synthesis of vitamin D. Vitamin D is beneficial for bone health and increases calcium absorption in the body. However, at the same time, Ultraviolet (UV) rays from the sun can also be a major threat to skin health. Overexposure to UV rays can seriously damage our skin. Therefore, sunscreen is the skin’s first and foremost shield against these harmful UV rays.

Apart from being a shield, sunscreen also plays a role in preventing hyperpigmentation, a condition where the skin color becomes uneven with the appearance of dark patches or blemishes. There are several types of hyperpigmentation, namely: Lentigo, melasma, and post-inflammatory hyperpigmentation. If this has already happened, it will be more difficult for us to get rid of it!

Also, hyperpigmentation isn’t the only problem we can avoid with sunscreen. Skin that is overexposed to the sun tends to age faster. Sunscreen helps protect the skin’s collagen, a protein that keeps skin firm and wrinkle-free. You don’t want your glowing skin to age quickly, do you? Especially if it’s already happened, this risk is also difficult to overcome!

Another reason why sunscreen is important for the skin can be seen in its function of reducing the risk of skin cancer. Exposure to UV rays can cause skin cell mutations, or what we call the precursors of skin cancer. Of course, all of this is one of the most serious and dangerous skin problems. But take it easy, with regular sunscreen application, we can avoid it.

Now that Sereni-Trees already understands how important the role of sunscreen is for our skin, we shall not be too lazy to use sunscreen again!

Difference between Physical and Chemical Sunscreen

After we understand the dangers and importance of sunscreen for the skin, the next step is to choose the right sunscreen! Generally, there are 2 types of sunscreen, namely physical sunscreen and chemical sunscreen. 

Physical sunscreens, otherwise known as mineral sunscreens, contain active ingredients such as zinc oxide or titanium dioxide. They work by forming a physical layer over the skin that reflects UV rays. The advantage of this type of sunscreen is that it works instantly after application and is suitable for all skin types, especially sensitive skin. However, they can leave a white cast on the skin and feel heavier.

Chemical sunscreens contain chemicals such as oxybenzone, avobenzone, or octisalate. They work by absorbing UV rays and converting them into heat before being released from the skin. The advantage of chemical sunscreens is that they are lighter, do not leave a white film, and are suitable for daily use. But, they may cause irritation to sensitive skin.

Which one is better? Both have their own benefits and drawbacks. It comes down to our own skin preferences and needs. 

For each skin type, there are more tips for choosing sunscreen:

• Dry Skin

If your skin is dry, choose a sunscreen that contains moisturizing ingredients like glycerin or hyaluronic acid.

• Oily Skin

Owners of oily skin should look for a sunscreen that is non-comedogenic. Non-comedogenic means it won’t clog pores and cause acne. Try to choose a water-based or gel sunscreen.

• Sensitive Skin

Sensitive skin needs a sunscreen that is free from chemicals so there is less chance of irritation. Physical sunscreen is the best choice for sensitive skin.

Do’s and Don’ts of Using Sunscreen

Now let’s get into the tips for using sunscreen that is good for the skin! It’s useless if you’ve been diligently using sunscreen, but it’s wrong and you end up not getting the benefits perfectly. Here, take note of the Sereni-Trees, Do’s of using sunscreen:

• Use at least SPF 30+

Make sure the sunscreen you use has an SPF of at least 30+. A higher SPF provides better protection against UV rays.

• Apply 15-20 Minutes Before Activity

Sunscreen needs time to penetrate into the skin and work. Different skin types need different amounts of time! 

• Choose Sunscreen Type According to Skin Type

Every skin type has different needs. Choose a sunscreen that suits your skin type, whether it’s chemical or physical sunscreen as well as the content and method of application (spray, cream, lotion).

• Use Sunscreen Every Day

Make sure to use sunscreen as the last step in your skincare routine! This will keep your skin protected throughout the day.

• Use on Unprotected Skin

Don’t forget to apply sunscreen on uncovered parts of the skin such as the ears, neck, and other parts exposed to the sun.

• Use Two Fingers/1 Teaspoon

Take enough sunscreen to protect the skin well, no need to overdo it! Two fingers or about a teaspoon is the ideal amount.

Easy right? There are actually not too many complicated things you have to do to apply sunscreen correctly. The last step is to avoid what we should NOT do with sunscreen:

• Sunscreen Application Only Once A Day

Once is not enough! Reapply every two hours, especially if you do a lot of outdoor activities.

• Not Using Other Protective Equipment

Sunscreen is not the only protection from UV rays. We can reduce the effects of UV rays by using other protective gear such as hats and sunglasses.

• Uneven Application

Make sure to apply sunscreen evenly all over your face and body. If not, you will end up with stripes and uneven results!

• Only Use Sunscreen in Summer

A common mistake is to only use sunscreen during summer or outdoors. In fact, UV rays are present all year round and we can still be exposed even indoors.

In conclusion, even though the skin is moisturized, hydrated, and nourished by all kinds of skincare, we must still use the shield that is sunscreen! Make sure to choose the right sunscreen for your skin type and condition. You also have to be diligent with your application!

Dangers of UVA and UVB Rays

Especially now when global warming has become more prevalent, we must always protect our skin from the fierce rays of the sun. Sunlight or UVA and UVB can provide a million negative risks to our skin. 

Here’s the difference between UVA and UVB:

• UVA light: The longest wavelength of all UV rays but with lower energy. These rays can penetrate the skin and usually the negative effects will be seen sooner. Examples include sunburn and dark spots. It can also lead to premature ageing and skin cancer in the future!

• UVB rays: In contrast to UVA rays, these rays have higher energy but shorter wavelengths. Instead of entering the skin, these rays can directly damage the skin layer and its DNA. One example is that the skin may burn/damaged melanin.

Of course, continuous exposure to these two rays will have both short-term and long-term negative effects! This is where sunscreen comes in, as a protection from the sun. Whether the climate is hot or cold, sunscreen will protect us, that is why make sure to never skip using it!

Benefits of Sunscreen for Skin Health

Apart from protecting the skin from the sun, sunscreen plays a lot of roles in the health of our skin. Functioning as a protector, here are some of the things we can feel if we use this product regularly:

• Prevents premature ageing

Who wants wrinkles, sagging or dry skin? Of course no one! Therefore, in order to avoid this risk, both children, young people and adults must use skin protection with this sunscreen.

• Avoiding sunburn

Not only when playing at the beach must you use sunscreen! As long as the sun still appears, UVA and UVB rays are present. Especially if you have sensitive skin, you must really apply sunscreen and use other protections such as hats, umbrellas or long-sleeved clothes.

• Say no to blotchy skin

Blotchy skin is also known as hyperpigmentation, which means that certain areas of the skin look darker than others. If it happens, it will be difficult to get rid of it! Sometimes it even needs medical treatment. So, let’s just avoid it!

• Lower the risk of skin cancer

Sunscreen plays a role in reducing skin risks because it can protect our skin from UVA rays. But that doesn’t mean it’s impossible, we still have to keep ourselves protected from other factors besides UVA rays.

There you have it! Now we can all see how important is sunscreen to the health and wellbeing of our skin right? 

3 Types of Sunscreen

There are 3 types of sunscreen that we can choose according to our skin type. The first one is physical sunscreen. The active ingredients of this type are titanium dioxide and zinc oxide. The way it works is by becoming a fortress so that UV rays do not penetrate into our skin. For those of you with sensitive and dry skin, this type is ideal, especially since it doesn’t clog your pores. However, the downside is that it can leave a white cast, wears off easily and requires frequent re-application.

The second type is chemical sunscreens. The active ingredients of this type include oxybenzone and avobenzone. This one works by absorbing UV rays and converting them into heat to prevent them from entering the skin. If you have oily or acne-prone skin, this type of sunscreen will be perfect for you as it is light-textured and easy to absorb. But the downside is that it may trigger allergies and you have to wait for about 20-30 minutes for it to absorb properly. 

Finally, there’s the hybrid sunscreen type. As the name implies, this type is a combination of physical and chemical sunscreen. This is a new innovation that you should try as well because it tends to be more effective with less irritating ingredients. Perfect for those with sensitive skin!

Even so, to choose a suitable product, we always recommend researching the ingredients and conducting a patch test to avoid risks! 

Tips for Using Sunscreen

Nowadays in the beauty market, there are many application models, some are in the form of sprays, liquid, sticks and many more. It’s easy, just apply it to the skin!

However, there are a few things that we must remember:

• Using sunscreen is the last step in your skincare/makeup routine.
• Choose products with at least SPF 30 for strong protection
• Reapply after every 2 hours
• Use about 15-20 minutes before activities
• Always use sunscreen indoors or outdoors
• Don’t use too much or too little, humans need at least 35 ml of sunscreen per body.
• Apply to the skin surface evenly

It’s so easy, isn’t it? Now there’s no reason to forget or feel lazy in wearing sunscreen. Moreover, there are so many variations that we can choose according to our needs and comfort.

Remember, health is always a priority! After that, glowing, bright and flawless skin will appear by itself. Apart from using sunscreen or skin protection, make sure that skin hygiene and moisture are maintained. Plus, lifestyle and nutrition must be balanced!

Avoid These Skincare Mistakes

The increasing variety of skincare products can definitely be confusing. Especially when we use several products at the same time. Instead of increasing the risk of skin problems, Serenitree Squad can avoid the following skincare mistakes:

• Use moisturizer once only at night

Whether your skin is oily or dry, moisturizing is a must! But that doesn’t mean you just use it once a day at night. Especially for those of you with very dry skin, make sure to use it twice a day, morning and night.

• Not using sunscreen

As sophisticated as your skincare is, as expensive as it is, it will be useless without sunscreen! Skin that is not protected from the sun’s UV rays will be more prone to premature aging, dark spots, and even skin cancer. Therefore, even when indoors, keep using sunscreen!

• Over-exfoliating

Exfoliating is the process of removing dead skin cells so that the skin becomes brighter and smoother. There are generally 2 types of processes, namely chemical or physical. Excessive exfoliation can cause skin irritation, damaged skin layers and wounds. That’s why always look at the instructions for using the product first before use!

• Overuse of serums and face masks

Everything in excess can backfire on us. In the world of skincare, you shouldn’t try too many products at the same time. Especially if they’re not in the same range! The risk is that certain active ingredients conflict. This can lead to inflammation, irritation and skin burns!

If you don’t want to invite skin problems, Serenitree Squad must always be wise in using skincare. Always do your research, read the instructions and ingredients, and do a patch test. Stay safe and healthy always!

Do This Skincare Routine

Well, we’ve learned what we should avoid! Now it’s time to get your skincare routine right. Make sure to:

• Use moisturizer every morning and night

Moisturizers are meant to keep our skin moisturized and hydrated. With regular use twice a day in the morning and night, your skin will stay hydrated throughout the day. This is especially important for those with very dry skin. Don’t forget to use the type of moisturizer according to your skin type to make it more effective!

• Use skincare followed by sunscreen

As one of the most important skincare products, make sure to always apply sunscreen before traveling. Even when you’re just relaxing indoors. UVA rays from the sun can penetrate windows and doors, so don’t let your guard down! Use a sunscreen product with an SPF of at least 30. Remember to re-apply every 2 hours if you are in direct sunlight.

• Exfoliate according to the rules

Of course, to have smooth and bright skin, we need to exfoliate. However, the process can hurt us with excessive duration. Generally, we can only do physical exfoliation once a week and chemical exfoliation once a month. Be sure to look for signs of incompatibility after use. If negative effects appear, stop immediately.

• Using serums and face masks according to the rules

To prevent skincare ingredients from clashing with each other, always use serums 1 to 2 times a day and face masks 1 to 2 times a week. Try to use a skincare range from 1 or 2 brands only! Using too many different brands will be ineffective!

How about it, Serenitree Squad? How easy is your daily skincare routine! What skincare mistakes have you made?

Serenitree Tips

The information above is just the gist of a good skincare routine. Apart from these tips, there are some important things that are often overlooked! Even though they seem like trivial things, these factors help us improve our skin health!

Here are some things you need to look out for:

• Always cleanse your face properly before using any skincare. Wash your face and do double cleansing with a mild cleanser.
• Use skincare in the order in which you use it! Generally, the order of skincare use starts with cleanser, toner, serum, moisturizer, and sunscreen.
• Choose skincare that suits your skin type! There are many types of skincare out there, make sure to find one that suits your skin concerns and skin type so that it can work effectively!
• Store skincare in a dry and clean place, away from the sun or damp places. This way, the quality and hygiene of the product can always be maintained.
• Avoid leaving old products open without using them! First, the risk is that the efficacy of the product can decrease, besides that it is also easily contaminated with bacteria!
• Do not use skincare that has expired. Usually products that have or will expire will experience changes in texture and aroma.
