The Holy Grail of skincare, sunscreen is that essential product every beauty enthusiast swears by. You’ve probably heard everyone reiterate the significance of applying the magical potion whenever you step out of the house and for good reason. Sunscreen not only protects your skin from a tan, but it also prevents the damage caused by exposure to UV rays – early signs of ageing, hyper pigmentation, the works. And all of this is thanks to the workings of a “sun protection factor” also known as, SPF content present in a sunscreen.
You’ve probably come across a whole range of SPF sunscreens – varying from a mere SPF 15, going up to an SPF 60 to 100. It is quite logical to think a higher SPF would mean better coverage – but is it always necessary? Let’s break it down!SPF is an indication as to how much sun exposure you get the moment you step outside – this means, the longer the exposure to the sun’s rays, the higher the SPF. SPF 15 would protect you against 94 per cent of the UVB rays, SPF 30 against 97 per cent, SPF 50 against approximately 98 per cent…you get the picture. In short, the longer you intend to stay out in the sun, the higher your SPF content needs to be.
Do remember, that the SPF is only effective if you apply your sunscreen right. Applying a pea-sized amount isn’t going to be protecting you from very much, now is it? Keep in mind that you require about half a teaspoon of sunscreen for your face, while a good shot-glass size of sunscreen will do the trick for your body.
