SPF 101: Everything You Need To Know About Choosing The Right Sun Protection
Posted by Ritu Khanna on
Yes, sunblock is important, but do you know how to pick the correct one?
Sun protection is undoubtedly one of the most scientifically proven factors to avoiding skin damage. Because the sun’s harmful UV rays can lead to burns, dark spots, wrinkles, loss of skin elasticity and skin cancer, choosing the right science-backed sunblock is the only solution to prevent damage.
Look for a higher SPF
Sun Protection Factor is the measurement of how much longer the skin can stay in the sun without burning. It is recommended to use a sunblock of SPF 30 or higher. To get the full benefit, apply a thick, even layer to your face, ears, neck, lips, and décolletage, and other exposed areas of your body 20 to 30 minutes before stepping out. Reapply every two hours, or more frequently if you’re sweating or swimming.
Opt for antioxidants
While using sunscreen is a no-brainer, a formula that includes antioxidants like vitamin E can be even more beneficial. Studies suggest that antioxidants help neutralise and repair free-radical damage caused by the sun and can help promote collagen production.
Include blue light protection
Blue light, part of the sun’s spectrum, is known to damage skin. Our phones, laptops, and TVs emit it too, and increased exposure can cause skin to lose its luminosity. Choose a product which is labelled broad spectrum sunscreen—it offers protection against UVA (responsible for photo ageing) and UVB rays (causing burning and skin cancer).
Choose a physical sunblock
Unlike chemical sun protection, physical sunblocks are made of mineral-based ingredients. Zinc oxide and titanium dioxide as the most-commonly used ingredients that sit on the surface of the skin and scatter UV rays, rather than absorbing them into the skin. Iron oxide, another ingredient found in physical sunblocks, protects against blue light. Physical options are less irritating to sensitive skin, and hence are safer to use.
Learns the terms
Check if your sunblock is non-comedogenic, which means it won’t clog your pores or acne. You also want your sun protection labelled as ‘clear’ or ‘sheer’, meaning it won’t leave your skin looking chalky or ashy.
Our Perenne Sweatproof Sun Essential Broad Spectrum PA+++ SPF50 Gel Sunscreen is a great option if you want a physical sunscreen that includes blue light protection and moisturising antioxidants. It is paraben-free, cruelty-free, and is dermatologically-tested. It is also sweat-proof and water-resistant, and comes in a thin, non-greasy formula. Added bonus? It has a beautiful fragrance, unlike other sunscreens, thanks to the cocoa butter, green tea, and grapefruit extracts in it.
