Believe it or not, the best thing you can do for your skin daily is to apply a sunscreen.

UVA affects the skin’s elastin, leading to wrinkles and premature ageing (although it’s also linked to developing skin cancers). UVB is responsible for sunburn and can increase the risk of skin cancers, too. Certain sunscreens carry a UVA star rating from zero to five, which indicates how much UVA radiation they absorb, relative to UVB radiation. Don’t be alarmed if there isn’t a number on the bottle, though: the rating system was devised and is owned by Boots, so not all brands carry it. People can still use these types of sunscreens, but you should treat them like any other sunscreen, and reapply regularly,' he said. Sun cream provides protection from sunlight using UV filters. These are classified into two types: chemical and physical – also known as mineral sun cream.
