Of course we all know that we need protection from the sun, but what does all the jargon on a bottle of sunscreen really mean and how do you know you’ve chosen the right one?
First, we need to understand the nature of sunlight and
how the sun’s rays affect the skin. The
ultraviolet rays are the ones most people know – the UVA is associated with
ageing and UVB with burning. UVB rays
are the tanning rays, that reach the top layer of skin only and can cause
burning and ageing. UVA rays penetrate
much deeper into the skin and may add to the burning effect of the UVB rays as
well as the ageing.
