Scientists at Northwestern University in the US have developed a UV protective cream that can treat sunburn. Research results published In the journal Nature.
The cream contains synthetic melanin, a pigment substance found in skin cells (melanocytes) that protects the body against ultraviolet rays. In humans and animals, melanin provides pigmentation (shade) to the skin, eyes, and hair. This substance protects cells from damage by stimulating increased skin pigmentation in response to sunlight; the skin darkens and tans.
The product can be used to treat sun and chemical burns. The technology works by eliminating free radicals and reactive oxygen molecules formed as a result of biochemical reactions. Free radicals attack healthy cells, triggering the oxidation process. Their formation occurs during various damage to skin cells, for example, during burns. When applied to damaged skin, the synthetic melanin in the cream absorbs free radicals, reduces inflammation and stimulates regeneration.
The researchers also noted that eliminating free radicals also stops the destruction of collagen under the influence of ultraviolet light. Collagen is a protein that forms the basis of the body’s connective tissue and provides its strength and elasticity. Thus, the use of an innovative cream will prolong the youth of the skin.
