Chemical Sunscreen

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

Chemical Sunscreen — a sunscreen that uses organic (carbon-based) UV filters, such as avobenzone or octocrylene, that absorb ultraviolet radiation and convert it into a small amount of heat. These formulas tend to be lightweight and blend easily without leaving a white cast.

Key points

  • Chemical sunscreens use organic filters like avobenzone, octinoxate, octocrylene, and homosalate to absorb UV light.
  • They typically feel lightweight, spread easily, and rub in clear, making them popular for daily and under-makeup use.
  • Some traditional chemical filters are advised to be applied about 15 to 20 minutes before sun exposure, per the product label.
  • Availability of specific filters varies by country because sunscreen ingredients are regulated differently around the world.

Frequently asked

How is chemical sunscreen different from mineral sunscreen?

Chemical sunscreens use organic filters that absorb UV radiation, while mineral sunscreens use zinc oxide or titanium dioxide that sit largely on the surface. Both can offer effective broad-spectrum protection when properly formulated and applied.

Do I need to wait after applying chemical sunscreen?

Many chemical formulas are labeled to be applied roughly 15 to 20 minutes before sun exposure so they can settle. Always follow the specific directions on your product.
