Detailed answer

Corticosteroids have anti-inflammatory properties which can help reduce the inflammation and hyperpigmentation associated with melasma. They can be used topically as creams or ointments, or in some cases, orally. However, it is important to note that long-term use of corticosteroids may have side effects, such as skin thinning and increased sun sensitivity. Therefore, it is crucial to use corticosteroids under the supervision of a healthcare professional, and to follow their instructions and recommendations closely.
