While many provide protection against the UVB rays – responsible for sunburns and skin cancer
define – many do not shield against the UVA rays that penetrate deeper into the skin, causing it to age prematurely and also contributes towards skin cancer, the study conducted by Mintel Global New Products Database (GNPD) found.
Highlighting the importance of overall skin protection, Alexandra Richmond, senior beauty analyst at Mintel stated, “For a sunscreen to be as effective as possible, it should really protect against both UVB and UVA rays.”
“What many people may not realize is that if they just have UVB protection, they are less likely to burn but they have no protection against the harmful and ageing effects of UVA rays," she emphasized.
Looking at over 750 sun creams launched across Europe last year, Mintel, the market research firm, found that fewer than half offered complete protection against both UVA and UVB rays.
Importantly, the SPF factor numbered on the product label displays the products’ level of protection against UVB rays. However, this "factor" does not shield against dangerous UVA rays, researchers cautioned.
"Many people look for an SPF in their sunscreen, thinking that this offers them full protection against UV damage," Nina Goad, member of the British Association of Dermatologists said.
Urging consumers to carefully consider the type of sun cream they buy, Goad, laid stress on picking up products with specific UVA filters, indicated in the UK by stars or a circular UVA symbol.
One should buy a cream with at least 4 UVA stars or a UVA circle, signifying a high level of protection, Goad highlighted.
Furthermore, people should wear a minimum SPF of 15 at all times. However, this should be raised to an SPF of 30, if stepping out in extremely sunny weather, experts recommend.
