Dr. Nadir Qazi, a board-certified physician, says, “Sunscreen is the most important skin care product to maintain long-term skin health. It is vital in preventing signs of aging from appearing on the skin. Fine lines, wrinkles, and sunspots are all symptoms that can arise due to a lack of proper sunscreen application.” The effects of sunscreen may not be noticeable at first, but it will pay off long-term.

Why You Should Wear Sunscreen
Let us have a look at the top 11 interesting reasons why you should wear sunscreen throughout the year:
1. Shields From Harmful UV Rays
The continuously depleting ozone layer has put us at a higher risk of getting affected by the harmful rays of the sun. While you do need the sun for your daily dose of Vitamin D, it does not imply that you should put your health at risk! This radiation may lead to sunburn and skin damage. Sunscreens are critical products that protect you from the harmful UV rays (1).
2. Prevents Premature Aging
All of us love to have younger-looking, radiant, and healthy skin. This is one of the most convincing reasons to start using sunscreen. Indulging in outdoor activities without proper sun protection may accelerate signs of aging. Prevention is key and is possible with the help of sunscreen application. It shields your skin from developing signs of aging, such as wrinkles and fine lines, sunspots, hyperpigmentationi XA skin condition in which dark patches can occur in parts of the body due to increased melanin production. , photodamagei XSkin changes as a result of overexposure to the sun. This causes premature skin aging, hyperpigmentation, and freckles. , (sun damage), and dry skin. Studies reveal that people below the age of 55 who used sunscreen had 24% lesser chances of developing these aging signs than non-sunscreen and occasional sunscreen users (2).
3. Lowers Skin Cancer Risk
While people started using sunscreen mainly for beauty reasons, this health benefit comes as an advantage. Wear your sunscreen daily and over the days and months to shield your skin from the risk of various types of skin cancer (3). This is the worst type of skin cancer, which can be life-threatening for women as their age increases.
4. Lowers Blotchiness On The Face
Apply sunscreen liberally on your face to prevent the onset of that irritating blotchiness and eruptions of red veins. This can also prevent the onset of acne and other sun rays-induced damages caused by sun overexposure.
5. Prevents Sunburns
Sunburns can thin the skin, making it more transparent, and bruises become more visible. Your skin may experience repeated attacks of peeling, swelling, redness, hives, and itching. This is due to UVB rays, responsible for sunburns. The blisters can escalate the risk of skin cancer. A study published in ‘Annals of Epidemiology’ in August 2008 suggested that recurring occurrences of sunburns could actually put you at a higher risk of lethal melanomai XSkin cancer that develops in melanin cells, which give the skin its color. The disease can spread to other parts of the body. (4).
Moreover, a survey conducted on 4,088 adults in the US found that 79.6% of the participants reported using some form of sun protection the last time they experienced sunburn. Sunscreen was found to be the most common form of sun protection used, with 38.8% of the participants using it on the face, neck, and chest. 19.9% reported using sunscreen on the body, and 8.9% reported using makeup containing sunscreen.
So, apply sunscreen and stay safe.
6. Prevents Tanning
Tan is healthy. However, what you should be aware of is that while you are sunbathing to tan, you are at the risk of being harmed by the harsh UVB rays. Choose a sunscreen that has a minimum sun protection factor 30 to prevent tanning induced by UVB. Make sure you reapply sunscreen every two hours, especially if you have sensitive skin. Or apply it just after your exercise, as sweat could wash away the protective coating.
7. Enhances Health Of The Skin
The essential skin proteins, such as collagen, keratin, and elastin, are protected by sunscreen. These proteins are required for keeping the skin smooth and healthy. Make sure your sunblock has titanium dioxide in it to help reflect UV rays away from the skin and protect the activity of these proteins (5).
8. A Good Cosmetic Option
Nowadays, you get sunscreens that also double up as creams. Just apply it and leave it on. If you have dry skin or sensitive skin, make sure you reapply it every now and then for better safety of your skin.
9. A Wide Assortment To Choose
There are countless variants of sunscreens available in the market today. Plus, they come at affordable rates. You also can get sunscreen recipes online that you can prepare at home, making them even more cost effective.
10. You May Not Have To Reapply After A Swim
Most of the sunscreens or sunblocks available these days are waterproof. This enables you to enjoy yourself in the water, without burning yourself
11. Sunscreen Offers Better Protection Than A Full-Sleeved Dress
You cannot safeguard yourself from the sun by wearing a full-sleeved dress. Did you know that a cotton dress, particularly when damp, offers zero protection from the harmful rays of the sun? Just apply a generous amount of sunscreen under the dress as well.
How To Use Sunscreen
How to use sunscreen every day? If you are wondering about it, here are a few factors and sun safety tips that you need to keep in mind while picking up the sunscreen:
1. Always read the ingredient list and make sure your sunscreen contains the following:
- Titanium dioxide

- Avobenzonei XAn oil-soluble ingredient used widely in chemical sunscreens. It absorbs into the skin and shields it from UVA rays. (also parsol)

How Often To Use Sunscreens
Sunscreens act as a shield against the harmful UV rays which penetrate the skin’s barrier every time your skin is exposed to the sun. It is, therefore, advisable to use sunscreen every day. You may not notice the benefits now, but the advantage of using sunscreen is felt in the long run. If you are out in the sun for a long time either working or enjoying a sunbath on the beach or at the poolside, it is better to reapply sunscreen after every two hours to protect your skin from sunburns. Consult a dermatologist to learn more about sunscreen reapplication intervals best suited for your skin type.

Frequently Asked Questions
Why is sunscreen important even at home?
Dr. Hamdan Abdullah, a board-certified dermatologist, says, “It is important to wear sunscreen even at home as windows and other materials can allow UV rays to penetrate indoors. Moreover, if you work near windows or spend time outdoors, you may still be exposed to UV radiation. Thus, it is essential to use sunscreen regularly to protect your skin.”
Dr. Qazi adds, “Sunscreen is important anywhere there is ambient light. UV rays are not just found at the beach or on your local hike. There are two main types of ultraviolet radiation that affect our skin: UVA and UVB rays. UVB radiation levels increase during the hotter months and, most of the time, can be avoided in the shade. UVA is everywhere – everywhere that there is ambient light, in the shade, in buildings, during the winter and cooler months. Both types of radiation cause sun damage and can lead to severe health issues like skin cancer. It is crucial to apply sunscreen in the morning, reapply regularly throughout the day, and remove it at night before bed to help prevent skin cancer and premature aging due to sun damage.”
Can I skip moisturizer and use sunscreen?
Dr. Qazi says, “A chemical sunscreen should be applied before a moisturizer, and a mineral sunscreen should follow moisturizer in a skin care routine, but sunscreen is not a replacement for a nourishing moisturizer. Your skin type also plays a part in whether or not you should skip the moisturizer. People with more oily skin can apply moisturizer as a protective barrier to ensure the skin is hydrated and protected.” Nonetheless, there are some carefully formulated products that may enhance sunscreen’s overall skin protection properties.
Dr. Crystal Dinopol, MD, a dermatologist, adds, “There are a lot of sunscreens with added benefits like hyaluronic acid, niacinamide, ceramides, and so on that can replace your moisturizer in your morning routine. This saves a lot of time and money for most people who are busy and trying to maximize their skin care products.”
Should I wear sunscreen on rainy days?
Dr. Qazi says, “Sunscreen should still be worn on rainy days due to UVA rays still being prevalent even through the clouds.” Dr. Dinopol adds, “Sunscreen should be worn regardless of the weather. Clouds and rain do not block out UVA, which causes aging signs, and UVB, which causes sunburns.”
Can we apply sunscreen after moisturizer?
It is always good to apply sunscreen after you are done with your skin care regime as using serums or moisturizers over your sunscreen will affect the amount of protection it provides.
Can I use sunscreen while pregnant?
It is important to wear sunscreen while you are pregnant. Use one with at least an SPF of 30. Also, not all sunscreens are safe. There are many chemical sunscreens whose constituents can enter your bloodstream and can affect your fetus. It can also cause skin irritations and allergic reactions. Instead, use a natural sunscreen.
How long does sunscreen last once applied?
It usually lasts up to two to three hours, depending on the SPF. Ideally, the sunscreen should be applied 30 minutes before the skin is exposed to the sun. This allows the ingredients to bind to the skin properly. So, reapplying the sunscreen is as important as putting it on. Reapply it every two hours.
Does sunscreen over 30 SPF work?
Yes, sunscreens between SPF 30 and 50 work. However, there is only a tiny difference, SPF 30 protects against approximately 96% of UV rays whereas SPF 50 gives 98% protection from the sun. Therefore, a higher SPF does not necessarily mean greater protection.
What does the SPF number of sunscreen lotions mean?
The SPF refers to the ability of a sunscreen to block UVB rays that can cause sunburns, as well as UVA rays, that can cause deeper skin damage. The higher the SPF number, the higher the protection. But none provides 100% protection. The number shows the length of time your skin will be protected from burning, depending on your skin type. Check for the first sign of reddening in the sun without any protection (for eg., 3mins). Multiply that number by the SPF, that is, 50 * 3 (if the SPF is 50) = 150 minutes of sun protection.
Does expired sunscreen work?
All sunscreens have an expiration date mentioned on the bottle. The usual shelf life of a sunscreen is up to two to three years. However, you can still use it slightly over three years.
