Sunscreen Science: The Essential Shield Against UV Rays!

Regions near the equator or at high altitudes have strong ultraviolet radiation. Long term exposure to ultraviolet rays can lead to problems such as sunburn and skin aging, so sun protection is very important. The current sunscreen is mainly achieved through the mechanism of physical coverage or chemical absorption.

The following are several common effective ingredients currently used in sunscreen.

Sunscreen Ingredient	Absorption Range	Safety Index①
BP-3 (131-57-7)	UVB, UVA shortwave	8
UV-S (187393-00-6)	UVB, UVA	1
Etocrylene (5232-99-5)	UVB, UVA shortwave	1
Octocrylene (6197-30-4)	UVB, UVA shortwave	2-3
2-ETHYLHEXYL4-METHOXYCINNAMATE(5466-77-3)	UVB	5
Avobenzone (70356-09-1)	UVA	1-2
Diethylaminohydroxybenzoyl hexyl benzoate (302776-68-7)	UVA	2
Ethylhexyl Triazone (88122-99-0)	UVB, UVA	1
Bisoctrizole (103597-45-1)	UVB, UVA	1
TRIS-BIPHENYL TRIAZINE (31274-51-8)	UVB, UVA	No Data
Phenylbenzimidazole Sulfonic Acid(27503-81-7)	UVB	2-3
Homosalate (118-56-9)	UVB	2-4
ZnO (1314-13-2)	UVB, UVA	2-6
TiO2 (13463-67-7)	UVB, UVA	6
Benzotriazolyl Dodecyl p-Cresol (125304-04-3)	UVB, UVA	1

① The lower number means this ingredient is more safe.

The mechanism of chemical sunscreen is absorption and conversion. The organic compounds in chemical sunscreens can absorb the energy of ultraviolet radiation and convert it into thermal energy or harmless forms of light. This mechanism of action requires a chemical reaction with the skin, so some chemical sunscreen ingredients may cause certain irritation or allergic reactions to the skin. However, chemical sunscreens typically have better stability and permeability, forming a uniform and dense protective film on the skin surface, providing better sun protection effects.
