Skin pigmentation is like a double-edged sword, both beneficial to health and a factor that affects the aesthetics of the skin. Skin pigmentation can be disrupted by conditions such as genetics, disease, endocrine metabolism, nutrition... and cause diseases due to pigmentation disorders: Melasma, freckles, dark skin, albinism, vitiligo.

Hyperpigmentation causes dark spots or patches to appear on the face, arms, and other areas of the body that are directly exposed to sunlight. This condition is usually harmless, but it affects the aesthetics as well as the quality of life of people with this skin.

Melanin is considered the main cause of spots and dark spots on the skin. When the amount of melanin produced increases excessively due to factors such as direct exposure to sunlight, hormonal changes or aging, it will cause a number of conditions related to skin pigmentation such as: Hyperpigmentation, hypopigmentation and loss of pigmentation.

Hyperpigmentation is a common and usually harmless condition in which patches of skin become darker than the surrounding normal skin. This darkening occurs when excess melanin, the brown pigment that gives normal skin its color, forms deposits on the skin. Hyperpigmentation can affect people of all races.
