Sunscreens offer the best protection against sun damage. Wearing broad-spectrum sunscreen is something that should be a part of your everyday skincare routine, no matter which season. The rays of the sun are so harsh and damaging that applying it just once isn’t enough. You need to reapply your sunscreen every three hours for maximum protection.
Most of you know the benefits of sunscreen and may already be using one. But how do you know if it's the right one for you and doing its job effectively? This article will tell you what to look for in your sunscreen.
Sunscreen is a cream or lotion that blocks or deflects UV rays and prevents them from damaging your skin. There are two major types of sunscreen: chemical and physical.
Chemical sunscreen: When applied to the skin, chemicals sunscreen gets absorbed into the top layer. Instead of blocking the sun’s rays from entering into the skin, this type of sunscreen absorbs the UV rays, converts them into heat, and releases them from the body.
Physical sunscreen: Often called mineral or natural sunscreen, this type contains two essential ingredients: zinc oxide and titanium dioxide. Physical sunscreen acts as a shield against UV rays and reflects them instead of absorbing them into the skin.
The next thing you need to consider while purchasing sunscreen is your skin type. Heavy sunscreen may block your pores and lead to breakouts, especially if you have oily skin. Opt for a non-comedogenic formula. Those with dry skin should look for a moisturising ingredient in their sunscreens like hyaluronic acid or ceramides. Physical sunscreen is recommended to those with sensitive skin as it sits on top of the skin and protects it from UV rays.
A common myth about sunscreen is that the higher the amount of SPF, the better protection — that’s not true. SPF value is the number of UVB rays a particular sunscreen can filter out. Dermatologists recommend using a sunscreen with a minimum SPF value of 30 as it blocks about 97% of UVB rays. Always wear a generous layer of sunscreen and carry it in your bag for reapplication every three hours.
