Detailed answer

Melasma is a common skin condition characterized by the appearance of dark patches on the skin, typically on the face. It is believed to be primarily caused by a combination of genetic factors, hormonal changes, and sun exposure. Melasma does not have a direct impact on skin pH levels. Skin pH is influenced by various factors, such as age, environmental factors, skincare products, and skin disorders. However, melasma can make the skin more sensitive and prone to irritation, which may indirectly affect the skin's pH balance if products that disrupt the pH are used. It is important to choose skincare products that are gentle and formulated to maintain skin's natural pH level, especially for individuals with melasma or sensitive skin.
