We’ve all been through this: which is better for us? Is there even a difference…well, what is the difference?
Well, sunscreen contains chemicals that protect your skin by absorbing and reflecting UV ray and allows a certain range of UV light to be absorbed into the skin. It helps protect against UVA and UVB rays.
On the other hand, sun block contains physical ingredients that reflect and scatter the UVB light and acts as a wall between your skin and the sun. This is a better choice for you if you have sensitive skin.
The bottom line – most lotions are a combination of both sun block and sunscreen, so read the fine print to know what you are putting on your skin. Also, be sure to look for sunscreen or sun block that does not have vitamin A, retinol or retinyl palmitate which might break down in sunlight to photomutagenic compounds.
