Hypopigmentation refers to patches of skin that are lighter than your overall skin tone. Your skin’s pigmentation, or color, is based on the production of a substance called melanin.
If your skin cells don’t produce enough melanin, the skin can lighten. These effects can occur in spots or may cover your entire body.
Genetic and severe environmental conditions can cause melanin disruption. It’s important to identify the root cause before undergoing treatment.
Hyperpigmentation is a common, usually harmless condition in which patches of skin become darker in color than the normal surrounding skin. This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin. Hyperpigmentation can affect the skin color of people of any race.
