Zinc oxide is a mineral substance that has long been utilized by health product brands in all its forms – think diaper rash ointments, for example – and can also act as an effective sun filter.
Unlike a chemical-based sunscreen, zinc oxide sunscreen does not penetrate the skin. Instead, it remains on the surface, creating a robust physical barrier to UV rays.
When some people think of zinc oxide, they imagine a thick, white coat that resembles garage door paint, but fortunately, you can find zinc oxide sunscreen that doesn’t leave any residue and glides onto the skin very easily.
