How to keep your skin healthy and full of youthful charm?

According to the data, ordinary people can cause skin cancer by 5000 hours of sun exposure, and the sun exposure time refers not only to the exposure of the sun in summer when the sun shines, but also to all daily contact with the sun throughout the year. Therefore, every time you sunburn, you get closer to this 5000 hours, and it is even more dangerous to expose the skin directly to the sun. So sun protection must be done throughout the year.

Sunscreen, the most representative is to apply sunscreen products. Sunscreen products are divided into physical sunscreen products and chemical sunscreen products. Physical sunscreen is like wearing a top hat. When it is applied, a covering film is formed on the skin surface to block UV rays, but the coating is white and sticky and thick, which limits its practicality. Chemical sunscreen is a molecule that passes the effective chemical ingredients in sunscreens and is absorbed through skin epidermis. It interacts with UV rays to transform them into harmless energy, which is generally transparent and refreshing. The sunscreen of chemical products mainly refers to the prevention of ultraviolet (UVB) radiation. Therefore, it is best to choose UVB products, UVB can make the skin not be suntan, sunburn, skin health, youthful charm.

Experts of the Guangdong Pharmaceutical College discovered in the study a new UVB sunscreen chemical, trans-p-methoxycinnamate, with low internal energy, more stable, and higher activity. Can effectively control the UVB (280 ~ 320nm region) sunburned skin, no erythema, blisters and other daylight dermatitis. Ethyl p-methoxycinnamate has a broad and strong absorption in the 280-320 nm region, and its absorption peaks and peaks are excellent. It is non-irritant to the skin and has good safety. It is an ideal sunscreen agent.

Cosmetics made from trans-p-methoxy cinnamate as raw material not only effectively protect the skin from ultraviolet rays, but also can utilize another magical effect of p-methoxy cinnamate - natural broad-spectrum antibacterial effect To prevent the decline of the skin's resistance to disease, prevent the intrusion of bacteria, and prevent the occurrence of skin cancer.
