Go slowly if
Skin is sensitive or already irritated; SPF is a must because AHAs can make skin more sun-sensitive
How I'd use it
Use a few evenings a week or, with gentle formulas, in the morning with SPF. Do not stack with other strong exfoliants on the same night.
From my shelf
Lactic acid is the AHA in my Medicube pads (4.5%). It fits what I notice most: smoother skin and a more radiant look.
