There are two types of active ingredients that block UV rays: chemical and physical. Chemical ingredients undergo a chemical reaction to convert UV rays into heat to prevent sun damage. Physical ingredients physically absorb UV rays to keep them from the skin and prevent sun damage. They are considered almost perfect sunscreens as they are chemically inert, safe, and protect against the full UV spectrum.

Chemical sunscreen

  • Avobenzone – Avobenzone is a dibenzoylmethane derivative. It degrades quickly on its own when exposed to sunlight so it is often combined with photostabilizing ingredients that give it staying power in sunscreen. It does not protect against UVB rays.

  • Octinoxate – Octinoxate is a cinnamate ester and absorbs UVB rays from the sun. It is often combined with nanoparticles and water-resistant ingredients to keep it localized to the skin and to prevent absorption.

  • Oxybenzone – Oxybenzone is a benzophenone derivative and absorbs UVB and UVA II rays from the sun to protect your skin.

Physical sunscreen

  • Zinc oxide – Zinc oxide is a physical sunscreen that absorbs up to 360 nm of UV radiation and protects against both UVB and UVA rays.

  • Titanium dioxide – Titanium dioxide is a physical sunscreen that absorbs up to 400 nm of UV radiation and protects against both UVB and UVA rays.
