# Dullness

## Quick Summary

Dullness is the visible appearance of skin that looks lackluster, rough-textured, or lacking glow. It often stems from accumulated dead-skin cells on the surface, slowed cell turnover, dehydration, or a combination. Controlled exfoliation is one approach; cadence matters more than aggressiveness.

## Causes

Dullness can come from thick surface buildup, slower visible turnover with age, dehydration that flattens light reflection, excess sebum oxidation, and rough texture after irritation. These patterns can overlap, which is why exfoliation helps some dull-looking skin but is not the whole glow routine.

When dullness is mostly surface buildup, AHAs and BHAs can help. When the skin is dry or irritated, hydration and recovery may matter more than adding another acid.
