Lactic Acid: Exfoliation, Moisture, and Choosing a Product

Short Answer

Lactic acid is an alpha hydroxy acid used to smooth rough skin and improve surface texture. Some formulas also support hydration, but the ingredient can still sting and irritate sensitive skin.

Benefits

• Can smooth the appearance and feel of rough skin.
• May help dull-looking skin appear more even.
• Can combine exfoliation with moisturizing ingredients in a finished formula.

How to Use

Follow the directions for the specific format. Rinse-off cleansers and leave-on treatments have different contact times. Begin with one exfoliating product and avoid adding a scrub or peel at the same time. Use a simple moisturizer if needed.
