Detailed answer

Hyperpigmentation is primarily caused by an overproduction of melanin in certain areas of the skin, usually due to sun exposure, hormonal changes, or skin inflammation. Electric appliances do not directly contribute to hyperpigmentation. However, certain appliances may emit heat or radiation that can potentially worsen existing hyperpigmentation or cause skin sensitivity, leading to increased pigmentation. It is important to remember that everyone's skin reacts differently, so it is essential to take appropriate precautions such as using sunscreen, protective clothing, and limiting direct exposure to heat or radiation from appliances. If you experience any concerns or notice changes in your hyperpigmentation, it is recommended to consult with a dermatologist for a personalized assessment and advice.
