Detailed answer

Melasma and post-inflammatory erythema can have similar appearance, making it possible for mistaken identity. However, there are some distinguishing factors between the two. Melasma is a hyperpigmentation condition that commonly affects sun-exposed areas of the face, whereas post-inflammatory erythema is a redness or flushing of the skin caused by inflammation or trauma. Melasma tends to have a more distinct and uniform pattern, often appearing as brown patches with well-defined borders. On the other hand, post-inflammatory erythema is characterized by red or pink patches that may be accompanied by swelling or tenderness. It is important to consult with a skincare professional for accurate diagnosis and appropriate treatment for these conditions.
