What do you mean by mineral sunscreens reflect rays while chemical sunscreens absorb rays?

Approved sunscreen ingredients come in two forms, mineral and chemical filters. Each works differently to protect your skin from UV rays. The chemical sunscreens like methoxycinnamate, oxybenzone, avobenzone and the like work by absorbing into your skin and absorbing the UV rays. Besides the likelihood of irritating skin and the toxicity that has been associated with many of the chemical sunscreens, we simply don’t like the idea of putting something on your body to absorb something that we don’t want on or in our bodies. Titanium dioxide and zinc oxide sit on top of your skin and work by reflecting and scattering the UV light away from the skin… Make sense?
