We will look at the science behind sunscreen, the importance of using it regularly, and tips for incorporating sunscreen into your daily routine. Whether you are a skincare enthusiast or simply looking to protect your skin, read on to learn more about the benefits of sunscreen and how to use it effectively.
Sunscreens are absolute necessary when it comes to skincare aging. They not only prevent us from getting tans and permanent resistant darkening over our skin but they also help prevent aging to a great extent. It is very important to understand the right usage and the right choice of sunscreens. “Sunscreen should always be worn as your last step that is post cleansing. Toning moisturizing sunscreen should be the final step of your regime. Now there are a lot of times where people feel that their makeup is providing an SPF. It is very important to understand that SPF is not an exact measure of the protection which the sun screen is providing you. There are other measures which have to be noticed and there are other filters which are present in sunscreens, including chemical and mineral sunscreen which helps prevent persistent pigment darkening of the skin and that also prevents solar aging,” says Dr Sonali Kohli, Consultant Dermatologist and Venereologist, Dermatology department, Sir H. N. Reliance Foundation Hospital and Research Centre.

Thus, it is very important that even if your makeup has an SPF you still do use a sunscreen. It is important to apply your sunscreen prior to starting the usage of your makeup.
“If you’re outdoors in a sunny area, it is sensible to apply sunscreen every two to three hours as the sunscreen ingredients which are present primarily get oxidized and breakdown on the skin and are not capable of providing further protection beyond two hours,” adds Dr Kohli.

Right application of sunscreen
The right application of a sunscreen is something that we refer to as the one fingertip unit method. That is the actual amount of sunscreen that should be reapplied every two to three hours. If you are in the pool or in an area where there is excessive sweating due to the sun exposure. It is advisable to use gel-based water resistant or sweat resistant sunscreen as the sunscreens can get easily washed away. It is very advisable to use your sunscreen like a primer just before applying your makeup. There are also sunscreen mineral powders which can be reapplied as the last quote. These are not unnecessary steps but mandate steps to prevent skin from further damage.
