👉 Hyperpigmentation is a condition in which the skin appears to be pigmented on parts of the body, such as the face, hands, and legs. This can occur due to changes in melanin levels or exposure to certain chemicals. Hyperpigmentation can appear either as patches of color that do not show up well under the light, or as a full-blown discoloration of the skin. The cause of hyperpigmentation is often multifactorial, including environmental factors such as sun exposure
