The season of summer means hot and humid climate, dealing with the scorching sun and trying to protect your skin from sun damage. Sunscreens are used for that sole purpose. They are designed specifically to protect your precious skin from the harsh sun rays causing tan lines, skin damage and skin cancer. Studies say that a regular use of sunscreen with SPF 15 or higher, can reduce the risk of developing Squamous Cell Carcinoma (SCC) by 40% and reduce the risk of Melanoma damage by 50%. Choosing the right sunscreen for yourself can, not only help you prevent skin cancer but also maintain that healthy glow on your body.
History Of Sunscreens
From ancient Greeks to ancient Egyptians, Sunscreen was used throughout the history of mankind to protect themselves from the Sun. Ancient Greeks used to apply Olive Oil whereas in Egypt, the use of rice extracts and jasmine was popular to fight off the harmful rays.
In the early 1930s, South Australian chemist H.A. Milton Blake worked on an experiment to produce a cream to prevent sunburn. Meanwhile in 1936, the founder of L’Oreal, Eugene Schueller, developed a formula for sunscreen.
In 1938, an Austrian chemist known as Franz Greiter invented one of the first biggest sunscreen product. Greiter’s sun-screen was called “Gletscher Crème” or “Glacier Cream”. The chemical formula for Glacier Cream was picked up by a company called Piz Buin.
SPF:- The term SPF also known as Sun Protection Factor was invented by Greiter in 1962. It was invented to standardize the strength and percentage of effectiveness of any sunscreen product. An SPF rating is considered the measure of the fraction of sunburn-producing UV rays that reach the dermal layer. Consider the given example, “SPF 20” means that 1/20th of the scorching radiation will reach the skin layer (assume the sunscreen is applied evenly at a thick dosage of two to three milligrams per centimeter square).
Suppose a person develops sun-tan in 15 minutes of exposure to sun without applying any sun protection, that person will be able to avoid sun–tan for 150 minutes in that same sun with application of SPF 15 sunscreen.
Sunscreens can be categorized into two types-a) Chemical Sunscreens and b) Physical Sunscreens
Chemical sunscreens are nothing but a mixture of many chemicals made into existence to fight off UVA and UVB rays. These ingredients deactivate the sunlight that falls onto the skin and create a chemical reaction that can transform UV rays into a form of heat, which gets released by the skin.
Although people tend to buy chemical sunscreens instead of physical ones, since physical sunscreen like Zinc oxide leaves a white cast on your skin after application and Chemical Sunscreens get absorbed into the skin leaving no trace at all. But a lot of dermatologists prefer physical sunscreens over chemical ones as physical sunscreen is effective immediately after applying onto the skin. Whereas chemical ones take more time to get absorbed into the skin. Physical sunscreens are also long lasting and gentle on the skin as compared to chemical sunscreens.
Choosing The Right Kind Of Sunscreen
If you are unaware of what to look for in a perfect sunscreen?. Here are the tips to make your choice a bit easier:-
1. Proper SPF-
If you are looking for a sunscreen, you might have come across sunscreens containing SPF 15, 30, 50 etc. The sun protection factor is the measurement of sun’s effect on your skin. Higher SPF are said to be better at protecting, but Dermatologists say a sunscreen with an SPF 15 blocks about 94-95% of the sun’s dangerous rays. SPF 30 products block about 97 % of sun rays, and SPF 45 sunscreen covers about 98 percent of the body from sun’s harmful UV rays. So, it is pointless to go for SPF higher than 45.
2 .PA Or Protection Grade Against UVA Rays-
PA is the Japanese sun protection measurement ranking used in today’s products. Sunscreens with PA+++ can protect normal skin people against UVA rays with a high grade of 8 or above. More ‘+’, more will be the protection.
Not everyone has the skin type. Some have normal skin, some have dry, some have combinational skin, some oily and others have sensitive skin. So, finding a sunscreen that fits your skin type is tough. People with normal skin have it easy, as their skin is not that sensitive to any chemicals than can cause breakouts. Dry skin people should focus on getting a sunscreen which can also moisturize and people with oily skin should opt for a sunscreen which does not clog the pores and feels light on the skin. Combination skin is a mix of both dry and oily at the T zone, nose, chin regions. A light weight sunscreen with a serum or gel like texture is well fit for combinational skin. People with sensitive skin face a lot of challenges when the deal with skin care so consulting a dermatologist before picking a sunscreen is strongly recommended as the chemicals in a product can cause breakouts and acne for a sensitive user.
People with lighter skin tone are more prone to sun burn rather than people with darker skin tone, as dark-skin people have more melanin pigment in skin that protects them from being sunburnt for a longer amount of time. However this does not mean that they are free from skin damage. A person with high amount of Melanin also has the chance of getting skin cancer if they do not take care of their skin and protect it from harmful rays.
Type Of Sunscreen (Powder, Mist, Stick, Gel Or Cream)
Nowadays there are a variety of different types of sunscreens available. But some of them are less effective than the others. Powder and mist sunscreen may be easy to use but due to their spray like application a lot of product might go to waste instead of being applied to the skin. Sunscreens with cream or gel like consistency can be less wasteful but messier to apply. Stick or roll on sunscreens on the other hand have better applications, so a lot of consumers prefer the stick kind.
Instead of chemically formulated sunscreens, products with zinc oxide or titanium di oxides are softer on skin and preferred by dermatologists. But Zinc and Titanium sunscreens can cast a white layer on skin after application which is more visible for people with darker skin tone. These people can choose chemical sunscreens to avoid the white cast.
Based On The Activity –
If you are an athlete or Swimmer or your job requires you to stay outdoors most of the time. Chances are you will get sun burn more than your peers. So, you should get a sunscreen with higher long-lasting coverage. You can also opt for water resistant ones if sweating or water is an issue.
1. Water Proof Or Water Resistant-
Sunscreens claiming to be “waterproof” have now been replaced to “Water Resistant up to 80 mins” by the FDA due to lack of proof of them being unaffected by water. So, Water resistant sunscreens are good for swimming or profuse sweating for up to 80 minutes after application.
2. When To Apply Sunscreen And For How Long?-
You should apply a generous amount of broad spectrum [including both UVA and UVB] SPF 35-50 sunscreen at least 10-20 minutes before sun exposure, and reapply every two hours after initial application if necessary.
3. Sun Exposure-
Sun shines the brightest from 11 A.M. to 3 P.M. So it would be better to avoid direct exposure to sunlight during that time cycle. Sunscreen and Umbrellas can help with sun exposure if you have to stay out during a longer period of time.
Multipurpose sunscreens formulated with moisturizing ingredient and foundations have low sun protection ability as other ingredients in a sunscreen can dilute out the sun protection factor.
Here is a guide on how to prep the skin and put on makeup while using a sunscreen:-
- Wash your face clean with any sulphate free face wash.
- Always use a moisturizer with the sunscreen as a base coat so the sunscreen does not dry out your face. Aloe Vera gel is a recommended moisturizer for people with oily skin or acne prone skin. Aloe Vera gel does not clog any pores and hydrates the skin.
- Use a coin sized amount of sunscreen for your whole face and do not forget to apply it on your neck as well. Applying sunscreen on neck can prevent appearance of wrinkles and fine lines.
- If it is a chemical sunscreen, it must be applied 15-20 minutes before going out of your house and thoroughly massaged into the skin so that it gets absorbed properly.
- If you are used to applying foundation in the morning, then the next step is your foundation. People applying physical sunscreen are required to apply a coat of foundation to mask off the ashy look.
- Don’t forget to apply a lip balm preferably with sun protection factor to protect the lips from sun damage as well.
If you are torn between buying a chemical or physical sunscreen, it is always advised to do some research about the product and consulting a certified Dermatologist for more help. Because your skin is one of your precious assets and must be cared for in the best way possible.
