Detailed answer

Hyperpigmentation is a condition characterized by dark patches on the skin. It is primarily caused by an excess production of melanin, the pigment that gives color to our skin. The development and severity of hyperpigmentation are influenced by various factors such as sun exposure, hormonal changes, and skin inflammation. However, cold temperatures or wind alone do not directly worsen hyperpigmentation. These environmental factors may cause temporary redness or dryness, but they do not have a direct impact on melanin production or the darkening of hyperpigmentation. It is important to protect the skin from sun exposure and use a broad-spectrum sunscreen to prevent further darkening of existing hyperpigmentation.
