Evy sunscreen mousse SPF10 is recommended for those who rarely or never burn. It is also suitable for more robust areas that have already got some colour or as an alternative if you are in weaker sunlight or not going to be out for so long. SPF 10 means that 1/10 of UVB rays through. Protection blocks 90% of UV rays, provided you use the amount recommended. Just like all our products it has the highest UVA protection, over 90%.
