Detailed answer

Hyperpigmentation is a condition characterized by the darkening of patches of skin due to excessive melanin production. While constant use of tight-fitting shoes or footwear can cause skin issues like blisters, corns, or calluses, it does not directly lead to hyperpigmentation. Hyperpigmentation is typically caused by factors such as sun damage, hormonal changes, post-inflammatory response, or certain medical conditions. However, if tight shoes cause irritation or friction on the skin, it could potentially worsen pre-existing hyperpigmentation on affected areas. It is always advised to wear properly fitted shoes and take necessary precautions to avoid any discomfort or skin problems.
