The skin can self-synthesize melanin, if this synthesis ability is reduced, the skin will become sensitive. The incidence of skin cancer in many European countries is higher than that of African blacks. For this reason, melanin can actually protect our cells from damage.

Ultraviolet stimulation leads to the production of melanin

There are pigment mother cells in the skin epidermis of everyone, which can secrete melanin pigment. When ultraviolet rays irradiate the skin, the skin will be in a state of "self-protection", because the ultraviolet rays stimulate the melanin pigment and activate the activity of tyrosinase to protect our skin from damage. Tyrosinase reacts with tyrosine in melanin pigment to produce a substance called "dopa". Dopa is accelerated into dopaquinone under the action of tyrosinase. Dopa is actually the precursor of melanin, which is formed by oxidation of tyrosine and releases melanin.

Melanin precipitation forms sunburn

Under normal circumstances, if the produced melanin decomposes and peels off normally during the metabolic process, it will not affect the skin color. Once the metabolism in the body is disordered, when the sun is exposed or the endocrine changes, the melanin cannot be metabolized in time, and it will precipitate in the bottom layer of the epidermis, making the skin color dark; if it is only partially precipitated, it will form spots or deepen the original spots. Spots are born!

What does sunburn look like?

Shape: oval, protruding or smooth, with indistinct and regular boundaries.

Color: mainly dark brown, but also light brown.
