Detailed answer

Heat exposure can have a negative impact on melasma by triggering pigment-producing cells in the skin, known as melanocytes. Increased heat can stimulate the production of melanin, leading to heightened pigmentation and a worsening of melasma symptoms. This is particularly true in individuals with a predisposition to melasma or those already experiencing hyperpigmentation issues. Heat from prolonged sun exposure, hot weather, saunas, or hot showers can all contribute to the worsening of melasma. To minimize the impact of heat on melasma, it is crucial to protect the skin from excessive heat and sun exposure by wearing broad-spectrum sunscreen, seeking shade, wearing wide-brimmed hats, and using protective clothing. It is also advisable to avoid excessive heat sources and to maintain a cool and calm environment for the skin. Additionally, incorporating skincare products containing ingredients like hydroquinone, retinoids, vitamin C, or niacinamide into a skincare routine can help manage melasma and prevent the exacerbation caused by heat exposure. Consulting a dermatologist or skincare professional for personalized advice and treatment options is recommended for individuals with melasma.
