The Exception to the rule for phototype 6

The majority of pigment spots on black and mixed skin are due to an inflammatory phenomenon. Acne, eczema, injuries, hormonal imbalances … will cause inflammation of the skin leading to stimulation of melanin synthesis, which will give more or less dark spots on the skin. We can correct all these spots – or almost – by a thorough treatment that fights against the problem, case by case, at the origin of these spots.
Tip: pair with local anti-dark spot cosmetic treatments to restore uniform color to the skin. In the sun, sun protection is accentuated with an index of 50, no less
