Why Sunscreen Is Important in Summer 2023

There are many reasons for using sunscreen against UV rays, even indoors. If you ask why is sunscreen important? We have the answer for you. The benefits of sunscreen go above protecting your skin from the sun’s rays. Summer means it is time to run to the shop to buy sunscreen lotion. However, we should apply sunscreen daily for the best results.

It does not matter whether it is winter or summer; you must protect your skin from sun exposure, and SPF helps you with this. It is scientifically proven that sunscreen is the most essential skin care product to maintain long-term skin health. 

This article will discuss the benefits of sunscreen, how to use it, and how often you must apply them. Take a look.

Why is sunscreen important to use

Sunscreen works as a barrier for your skin from the harmful sun. Depending on the elements in the sunscreen, the UV rays are either ricocheted off or absorbed by the chemicals. However, it does not provide 100% defence from the sun, as a small amount of UV radiation still reaches our skin. Using sunscreen as a barrier helps to protect our skin from skin damage, ageing, wrinkling, and even cancer.

Basics of Sunscreen

Sunscreen comes in many forms, including creams, sprays, and lotions. They are labelled with a sun protection factor (SPF) number, which acts as a guide for their relative strength. It refers to the sunscreen’s ability to filter out UVB only, not UVA.

It is essential to note that the SPF does NOT indicate the length of protection, but rather the strength of the defence. For example, SPF 15 filters out 93% of UVB, allowing 7% penetration to the skin, whereas SPF 30 filters out 97% of UVB, allowing 3% penetration. Sunscreens labelled as broad-spectrum protect against both UVA and UVB.

Ten reasons why you should wear sunscreen daily

1. Protection From Harmful UV Rays

The constantly depleting UV ray has put us at a higher risk of getting impacted by the sun’s dangerous rays. While you need the sun for your everyday dose of Vitamin D, it does not mean you should risk your health! This radiation may lead to skin damage and sunburn, but Sunscreens are essential products that save you from harmful UV rays.

2. Prevents Premature Ageing

Everybody wants radiant, younger-looking, and healthy skin, which is one of the most effective reasons to use sunscreen. Indulging in outside activities without proper sun safety may accelerate ageing symptoms, and prevention is key, and it is only possible with sunscreen application.

It saves your skin from growing signs of ageing, like wrinkles and fine lines, hyperpigmentation, sunspots, photodamage, and dry skin. Moreover, most studies show that people under 55 who used sunscreen had 24% fewer possibilities of developing these signs of ageing than occasional sunscreen and non-sunscreen users.

3. Reduces the Risk of Skin Cancer

Most people started using sunscreen specifically for beauty reasons, and this health benefit comes as a benefit. Wear sunscreen every day and for months to shield your skin from the risk of different types of skin cancer. It is the most harmful type of skin cancer, which can be life-threatening for ladies as their age increases.

4. Prevents Sunburns

Sunburns can make the skin thin, making it more transparent, and bruises become more visual. However, your skin may experience repeated attacks of swelling, peeling, redness, itching, and hives. It is because of UVB rays, which are responsible for sunburns, and the blisters can escalate the chance of skin cancer.

5. Lowers Blotchiness On The Face

To prevent the onset of that annoying blotchiness and eruptions of red veins, apply sunscreen liberally on your face. It can also stop the beginning of acne and other sun rays-induced harms caused by sun overexposure.

6. Prevents Tanning

Tan is good, but not for everybody. However, you must be aware of being damaged by the harsh UVB rays. Pick a sunscreen with the lowest sun shelter factor of 30 to prevent tanning caused by UVB. Moreover, ensure you reapply sunscreen every two hours, specifically if you have sensitive skin. You can apply it after exercise, as sweat could wash out the protecting coating.

7. A Good Cosmetic Choice

These days, you get sunscreens that even double up as creams. Simply apply it and leave it on. Moreover, if you have sensitive or dry skin, ensure you reapply it daily for better skin safety.

8. Improves The Health Of The Skin

The vital skin proteins, like keratin, collagen, and elastin, are covered by sunscreen, and these proteins are needed for keeping the skin healthy and smooth. Moreover, ensure your sunscreen has titanium dioxide that helps reflect UV rays away from the skin and protects the exercise of these proteins.

9. It Offers Better Protection Than A Full-Sleeved Dress

You cannot protect yourself from the sun by wearing a full-sleeved dress. Did you know that a cotton dress, especially when damp, offers zero protection from the sun’s damaging rays? Just apply a generous amount of sunscreen under the dress as well.

10. It Is Waterproof

Most sunscreens available these days are waterproof, enabling you to enjoy yourself in the water without burning yourself. You can try ALNA Sunscreen for better results.

Frequently Asked Question

1. Can I skip moisturiser and use sunscreen?

Yes, you can skip moisturiser and use sunscreen. Sunscreens are simply moisturisers that chemists have added UV filters for better sun protection, and they still provide moisturising benefits just like a normal moisturiser.

2. Should I wear sunscreen on rainy days?

If you’re stepping out, you need to apply sunscreen. Even if it’s cloudy or rainy. This is because the clouds don’t block the harmful UVA and UVB rays from penetrating your skin.

3. Can I use sunscreen while pregnant?

Yes. Pregnancy can increase your skin’s sensitivity, so wearing sunscreen is important to protect yourself from sun damage.

4. How long does sunscreen last once applied?

It generally lasts up to two to three hours, depending on the SPF. The sunscreen should be applied 30 minutes before the skin is exposed to the sun. You may not need a second application if you work indoors and sit away from windows.


Applying sunscreen daily across all seasons comes with a host of benefits. These include safety from harmful UV rays, lowering signs of premature ageing, stopping sunburns and tanning, and reducing the risk of developing skin cancer. Moreover, before using sunscreens, always choose waterproof broad-spectrum lotions containing zinc oxide and titanium dioxide.
