UVA and UVB rays
The sun emits two kinds of ultra-violet light: UVA and UVB. UVA is present all year round and can even cut through grey clouds and glass. It’s also responsible for deep structural damage to the skin which causes premature ageing in the skin and the depletion of important proteins such as collagen. UVB rays on the other hand are responsible for creating sunburn in the skin and create more surface-level damage. This is why it’s very important that you apply a sunscreen that protects from both UVA and UVB rays.
Did you know? There are around 500 times more UVA rays in sunlight than UVB rays.
