What is the difference between Physical and Chemical Sunscreen?


Finding the right sunscreen can be challenging in today’s world. The holy grail of sunscreen is a product that provides protection, won’t clog pores, and is safe for the environment. So what is the difference between Physical and Chemical and which one is right for you?

Physical sunblocks are mineral-based, using zinc and titanium. These minerals reflect the UV rays while sitting on top of the skin. Physical sunblocks do not get absorbed by the skin.

Zinc Oxide is a physical block that had the broadest level of protection. It projects against UVB, UVA ll, and most of the UVA l rays. Micronized zinc oxide is a more transparent alternative than the traditional white paste used by lifeguards.

Titanium oxide is also a physical block that protects against UVB and short UVA ll rays.

Chemical sunscreen contains organic compounds such as oxybenzone, octinoxate, octisalate, and avobenzone. The UV rays dissipate due to a chemical reaction. Topical products can be absorbed through the skin, giving people pause regarding the use of chemical sunscreen. Chemical sunscreens have an increased chance of irritation and stinging, and must be applied 20 minutes before sun exposure.

For the strongest sun protection, we recommend the following products

Zinc Physical Block
ISDIN Eryotona Altinica Lotion 50SPF

Zinc and Titanium Physical Block ISDIN Mineral Brush SPF 50
