One of the most frequent skin problems when the heat arrives and we are exposed to the sun are the dreaded spots. But why do they appear? Because the melanocytes, internal cells that produce melanin, see their functioning altered. Melanin is the brown pigment that we produce naturally and that gives color to our skin, our hair, and the iris of the eye.
When we are exposed to the sun, melanocytes increase pigment production to give us that much-desired tanned skin tone. Prolonged exposure without adequate protection causes an increase in free radicals which in turn further stimulate the production of melanin. During this process, various enzymes and hormones are involved: tyrosine and melanogenesis-stimulating hormone (called MSH: Melanin Stimulating Hormon) are the most prominent.
With aging, free radicals also stimulate the production of melanin and cell regeneration slows down, giving rise to the appearance of dark pigmentary spots. As the concentration of melanin increases, it ceases to be distributed evenly, thus causing the appearance of dark spots.
People with a light skin phototype are more likely to develop skin spots, so they should take extra protection during sun exposure. The most frequent areas of appearance are those most exposed to sun exposure: face, neckline and hands.
How to avoid the appearance of spots
- There are specific anti-stain assets that are based on blocking the production of melanin. A very novel asset is the melanin regulator: MSH-INHIB that acts directly on the melanocyte, regulating the production of this pigment. The skin recovers a uniform tone and the spots diminish.
- An interesting plant to avoid the appearance of spots is soy: with its regenerating and redensifying action it helps fight against skin ageing. Soy is flavones act on the fibroblast, stimulating the production of collagen and elastin, thus improving elasticity. In addition, they stimulate skin regeneration and redensify it. If you are looking for a drugstore product, we recommend theHomogene range from Plante System, since it offers a selection of creams adapted for skin prone to blemishes.
