A mild chemical exfoliant such as lactic acid or polyhydroxy acid (PHA), used twice weekly, accelerates the clearance of surface pigment. The objective is gentle support, not aggressive resurfacing. Over-exfoliation — daily acid use, mechanical scrubbing, or strong peels at home — causes inflammation, which is itself a trigger for further pigmentation. In skin of color, the risk of worsening hyperpigmentation through aggressive treatment is well-documented and should not be underestimated.
