Answer 1

1.Sunblocks blocks the ultra violet rays from reaching the skin by creating a layer of protection on the surface of the skin.Sunblocks uses zinc and titanium oxide. The ingredients contained in the sunscreen are formulated to absorb the majority of UV rays before they can reach the skin.It contains benzophenone and avobenzone which works to absorb the UV rays.

2.SPF is sun protection factor which is a number to indicate the level of protection from UVB rays and states whether or not it has passed a broad spectrum test against the UVA radiation.A product with higher SPF number will offer greater protection.

3.SPF 50+ is better.SPF 30+ gives high protection and SPF50+ gives very high protection.SPF 30+ filters 97%While SPF 50+ is an almost complete UVB block ,at 98%.
