Detailed answer

Chemical exfoliants work by removing dead skin cells from the surface of the skin, revealing a fresh layer underneath. However, using certain exfoliants too frequently or applying them too aggressively can lead to over-exfoliation and irritation. This can result in your skin looking dull and lackluster. Over-exfoliation disrupts the skin's natural barrier, causing dryness and inflammation, which can make your complexion appear dull. It is important to follow the instructions for product usage and avoid using chemical exfoliants too frequently or in excessive amounts to prevent dullness and irritation.
