Sudden appearance of dark spots on your cheeks could be due to solar lentigines (sun spots), post-inflammatory hyperpigmentation, or pigmented nevi (moles). Because these appeared suddenly, it is crucial to have them evaluated by a dermatologist before applying any medicated creams. Self-treating undiagnosed spots can cause irritation or delay proper diagnosis. In the meantime, protect your skin by applying a broad-spectrum sunscreen (SPF 30 or higher) daily to prevent further darkening. Avoid using harsh scrubs. Once a doctor confirms the diagnosis, they may prescribe targeted treatments like topical retinoids, azelaic acid, or suggest safe in-office procedures.
