Detailed answer

Hyperpigmentation occurs when the skin produces excess melanin, usually as a response to sun damage, hormonal changes, or inflammation. Constant use of computer keyboards or mice does not directly cause hyperpigmentation. The main causes of hyperpigmentation are prolonged sun exposure without protection, hormonal imbalances like melasma, post-inflammatory hyperpigmentation from acne or skin injuries, and certain skin conditions. Computer use can contribute to other skin issues like dryness, sensitivity, or redness due to lack of moisture, poor posture, or blue light exposure, but it does not directly cause hyperpigmentation. To prevent or treat hyperpigmentation, it is important to use sunscreen with proper SPF, avoid excessive sun exposure, and consult with a skincare professional for suitable treatments such as topical creams, chemical peels, or laser therapies.
