Once summer rolls around, we all make a beeline to the nearest drug store to stock up on sunscreen. Keep in mind, applying sunscreen should be done daily. Summer or winter, monsoon or spring, the need to protect your skin from the harsh rays of the sun is crucial. And, sunscreen does the job for you.
What Is sunscreen?
Sunscreens are products combining several ingredients that help prevent the sun’s ultraviolet (UV) radiation from reaching the skin. Two types of ultraviolet radiation, UVA and UVB, damage the skin, age it prematurely, and increase your risk of skin cancer.
UVB is the chief culprit behind sunburn, while UVA rays, which penetrate the skin more deeply, are associated with wrinkling, leathering, sagging, and other light-induced effects of aging. They also exacerbate the carcinogenic effects of UVB rays, and increasingly are being seen as a cause of skin cancer on their own. Sunscreens vary in their ability to protect against UVA and UVB.
What Is SPF?
Most sunscreens with an SPF of 15 or higher do an excellent job of protecting against UVB. SPF — or Sun Protection Factor — is a measure of a sunscreen’s ability to prevent UVB from damaging the skin. Here’s how it works: If it takes 20 minutes for your unprotected skin to start turning red, using an SPF 15 sunscreen theoretically prevents reddening 15 times longer — about five hours.
Another way to look at it is in terms of percentages: SPF 15 filters out approximately 93 percent of all incoming UVB rays. SPF 30 keeps out 97 percent and SPF 50 keeps out 98 percent. They may seem like negligible differences, but if you are light-sensitive, or have a history of skin cancer, those extra percentages will make a difference. And as you can see, no sunscreen can block all UV rays.
But there are problems with the SPF model: First, no sunscreen, regardless of strength, should be expected to stay effective longer than two hours without reapplication. Second, “reddening” of the skin is a reaction to UVB rays alone and tells you little about what UVA damage you may be getting. Plenty of damage can be done without the red flag of sunburn being raised.
Why sunscreen is important?
You are probably in the habit of only wearing sunscreen to the beach, pool or when you are planning on spending the day completely outside, right? Well the sun is up there 365 days a year and you need protection all 365 of those days. Why do you need a sunscreen in the winter? Because the snow and ice reflect sunlight, so although it may seem dark and gray outside you are still at risk!
You must wear an SPF of 15 or higher for all outdoor activities: shopping, errands, running etc. Make sure you are applying every 2 hours and use a broad spectrum UVA/UVB sunscreen. And make it water- proof!
And last but not least by any means! A study found that test subjects who used a daily sunscreen cut the speed of the skin’s aging process down by 24%, compared to those that did not. Hopefully the antiaging properties is enough to persuade you.
Benefits Of Sunscreen
#.Protects Skin From Harmful UV Rays
The constantly depleting ozone layer has put us at a higher risk of being affected by the harmful rays of the sun. While you do need the sun for your daily dose of Vitamin D, that doesn’t mean you should put your health at risk! Applying sunscreen blocks these harmful rays from penetrating the skin and triggering skin disorders.
Tan is healthy – this mindset still endures; however, what you should be aware is that while you are sunbathing to tan, you are at the risk of being harmed by the harsh ultraviolet B rays. Choose a sunscreen that has a minimum of sun protection factor 30 to prevent tanning induced by UVB. And, make sure you reapply sunscreen every two hours, especially if you have a sensitive skin. Or, just after your exercise, as sweat could wash away the protective coating.
#.It Prevents Premature Ageing
If ever there was a good enough reason to use sunscreen every day, it’s that it helps prevent premature ageing. We all take care of our skin with various cleansers, toners, and moisturisers, but all of this is for nothing if we don’t take care of our skin and protect it against harmful sun rays.
#.It Helps Protect Against Skin Cancer
Skin cancer is dangerous, and if you don’t protect your skin from the sun you run a higher risk of developing it. Sunscreen helps protect your skin against harmful sun rays and provides an extra layer of protection against skin cancer. Neglecting your skin and ignoring cancer warnings are just not worth it.
Sunburnt skin is painful and is simply not necessary to experience. Prevent the red, tender skin, bubbly blisters, itching and peeling by applying sunscreen to all exposed areas. Your skin will stay beautiful all summer long, and you won’t have any pain and discomfort.
#Something For Everyone
There are so many sunscreen products on the market, you’ll always find one that suits your needs. Whether you prefer a lotion, cream or a spray, or need a 15 SPF or 50 SPF, you’ll find the perfect sunscreen for your skin. And don’t think that it should only be applied in Summer. The rays which the sun produces can still do damage on overcast and cloudy days, not just clear days. Also use the highest SPF you can find to ensure your skin is properly protected.
#.Make Your Skin Healthier
Sunscreen contains ingredients such as keratin and elastin. These ingredients keep your skin looking young, healthy, and smooth. This makes it the perfect everyday product that protects and nurtures your skin.
#.Good Cosmetic Option
These days, you get sunscreens that also doubles up as a cream. Just apply it and leave on.
If you have a dry skin or sensitive skin, make sure you reapply a coating every so often for better safety of your skin.
