Detailed answer

Prescription medications can be used to treat melasma, a common skin condition characterized by dark patches on the face. These medications often contain active ingredients such as hydroquinone, tretinoin, corticosteroids, or a combination of these. Hydroquinone is a skin-lightening agent that reduces the production of melanin, while tretinoin helps to exfoliate and enhance skin cell turnover. Corticosteroids can help reduce inflammation and pigmentation. It's important to note that these medications should be used under the guidance of a healthcare professional, as they may have potential side effects and require monitoring.
