The symptoms of melasma are dark, irregular well demarcated hyperpigmented macules to patches commonly found on the upper cheek, nose, lips, upper lip, and forehead. These dark spots often develop slowly over time.
Rosacea is a chronic condition characterized by facial redness. Pimples are sometimes included as part of the definition. Unless it affects the eyes, it is typically a harmless cosmetic condition.
