Lu Lan Ji Na Sunscreen is good. Sun protection can be divided into physical sun protection and chemical sun protection. However, chemical sunscreen is better in skin feeling and visual effect, while people with sensitive or extremely dry skin are more suitable for physical sunscreen.

Physical sunscreen

Use sunscreen particles to form a protective layer on the skin surface, reflecting light waves that may harm the skin in ultraviolet rays, thus protecting the skin. Physical sunscreen particles generally stay on the skin surface and will not be absorbed by the skin, so the burden on the skin is relatively small and it is not easy to cause skin sensitivity.

Chemical sunscreen

Through the combination of some chemicals and cells, before the cells are damaged, the parts of ultraviolet rays that may harm the skin are absorbed first, so as to achieve the purpose of sun protection.
