Detailed answer

Hyperpigmentation is usually caused by factors such as sun exposure, hormonal changes, inflammation, or skin injuries. Constant use of facial cleansers or soaps is unlikely to directly cause hyperpigmentation. However, using harsh cleansers or soaps can potentially irritate the skin, leading to inflammation and post-inflammatory hyperpigmentation in some individuals. It is important to choose gentle facial cleansers or soaps suitable for your skin type and to avoid excessive scrubbing or rubbing. If you are concerned about hyperpigmentation, it is advisable to consult with a skincare professional for a proper diagnosis and personalized treatment plan.
