How to avoid pigmentation in summer?

06/29/2018

Blackening is the skin’s self-protection

The skin can self-synthesize melanin, and if this ability to synthesize decreases, the skin becomes sensitive. The incidence of skin cancer in many European countries is higher than African blacks, which is the reason that melanin can actually protect our cells from harm.

UV Stimulation Leads to Melanin Production

Each person has pigmented cells in the epidermis of the skin that secrete melanin pigment. When ultraviolet light shines on the skin, the skin will be in a state of “self-protection.” Because the ultraviolet ray stimulates the melanin pigment and activates tyrosinase activity, it protects our skin from damage. Tyrosinase reacts with tyrosine in the melanin pigment to produce a substance called “Dopa”. Dopa is accelerated by tyrosinase to become dopa quinones. Toba is actually the precursor of melanin, which is oxidized by tyrosine and releases melanin.

Melanin precipitation forms sunburn

Under normal circumstances, the melanin produced will not affect the skin color if it is normally degraded during the metabolism. Once the metabolic disorder occurs in the body, the sun exposure or endocrine changes, these melanin can not be metabolized in time, it will precipitate in the bottom layer of the epidermis, make the skin color black; if only a partial precipitation, it will form spots or deepen the original spot color, drying Spot it!
