Lactic acid is an ingredient that's in many prescription and over-the-counter topical skin products. It's an alpha hydroxy acid (AHA), which works by getting rid of dead skin cell buildup. Because lactic acid products made by different manufacturers have different age cutoffs, concentrations, and directions, it's important to follow the instructions on the package. Generally, you can apply lactic acid to the affected skin(s) two times daily. Lactic acid is typically used to relieve dry, scaly skin. Common side effects of this medication are temporary burning and stinging.

Pharmacist tips for Lactic acid
- Different formulations of lactic acid products have different directions. Always read the package labels for instructions and age limits before using lactic acid products.
- Lactic acid can make your skin more sensitive to the sun, which means you might sunburn more easily. This can happen even during the winter and on overcast days. Make sure to avoid sun exposure to the areas where you applied the medication. Wear protective clothing and a wide-brimmed hat, and use a moisturizing sunscreen while you're using lactic acid.
- To help with dry skin while using lactic acid, make sure to stay hydrated and avoid hot water and harsh skin products (e.g., soaps, hand sanitizers). Ask your dermatologist or pharmacist for recommendations on non-irritating, mild cleansers to use.
- You might experience mild stinging, burning, or peeling after applying lactic acid to your skin. This is temporary and should go away after a while. Be careful applying this medication to your face since your skin is more sensitive there. Talk to your dermatologist if side effects don't go away.
- Lactic acid should only be used on the outside of your body (i.e., intact skin). Don't use this medication on cuts, wounds, or burns. Avoid getting lactic acid near or in your eyes, lips, mouth, or nose.
- Store lactic acid up and away and out of children's reach and sight. This prevents them from accidentally swallowing medicine that was left out. If you think that your child might’ve accidentally swallowed lactic acid, call your Poison Control Center at 1-800-222-1222 right away even if you aren't completely sure.
