Glycolic, lactic, citric, and malic acids
Loosen the bonds between the dead cells in skin's uppermost layer so they can be shed, improving texture and adding radiance.
Clockwise starting top left:
A night lotion with glycolic acid and powerful moisture-retaining humectants, like
Olay Regenerist Night Resurfacing Elixir ($32; drugstores), is a gentle option
when your skin is dry.
To smooth away little bumps on your arms and legs, try
AmLactin Moisturizing Body Lotion ($16; drugstores). Lactic acid sloughs off dead skin cells that may be causing the bumps, and helps skin retain moisture.
The pads in
Dr. Dennis Gross Skincare Alpha Beta Face Peel ($78 for 30 applications;
dgskincare.com) are packed with AHAs, plus anti-inflammatory ingredients to combat irritation.
