Application of zinc oxide in physical sunscreen cosmetics:

Sunscreen is a skin care product that protects the skin from ultraviolet rays. Sunscreens have different defense index SPF (Sun Protection Factor), which means that it can extend the time to avoid sunburn under certain circumstances. The sunscreen is safe and effective, and one kind of sunscreen without irritation is physical sunscreen, that is zinc oxide powder for sunscreen.

1、Physical sunscreen: use the physical principles of sunscreen. The atomic particles of this sunscreen are flaky. When applied on the face, it acts like a mirror and reflects the sun to achieve the purpose of sun protection. TiO2 and Zno are both physical sunscreen ingredients. They can form a protective film on the skin so that ultraviolet rays cannot penetrate the skin surface, and both can fully protect against UVB, but the blocking of UVA is mainly based on zinc oxide powder for sunscreen.

2、Compared with TiO2, zinc oxide has better transparency. It is used in sunscreen cosmetics and will not block the pores of the skin, which can effectively reduce the burden on the skin.

3、Zinc oxide powder for sunscreen also has a certain calming and anti-inflammatory effect. It is a very good ingredient for sensitive skin and acne skin. Pure physical sunscreen products generally have a certain touch-up effect.

Zinc oxide powder for sunscreen provides more broad-spectrum protection than other sunscreens and can cover the wavelength range of 290~380nm. Zinc oxide has been used in care products for more than 300 years and can be applied to baby diaper cream and hot diaper water .
