Know the basics

What is lactic acid used for?

Lactic acid is keratolytic. Lactic acid increases moisture in the skin by softening/dissolving the horny substance (keratin) holding the top layer of skin cells together. This helps the dead skin cells fall off and helps the skin keep more water in.

How should I take lactic acid?

Some products need to be shaken before use. Check the label to see if you should shake the bottle well before using. Apply to the affected areas of the skin, usually 1-3 times a day or as directed by your doctor. Rub in well until absorbed. How often you apply the Lactic acid will depend on the product and your skin condition.

Apply to the skin/nails only. Avoid sensitive areas such as your eyes, lips, inside your mouth/nose, and the vaginal/groin area, unless your doctor directs you otherwise. Ask your doctor or check the label for directions about any areas or types of skin where you should not apply the product (e.g., on the face, any areas of broken/chapped/cut/irritated/scraped skin, or on a recently shaved area of the skin). Consult your doctor or pharmacist for more details.

Use Lactic acid regularly to get the most benefit from it. Most moisturizers need water to work well. Apply the product after bathing/showering/shampooing while the skin is still damp. For very dry skin, your doctor may instruct you to soak the area before using the product. Long, hot, or frequent bathing/washing can worsen dry skin.

Inform your doctor if your condition persists or worsens.

How do I store lactic acid?

Lactic acid is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store Lactic acid in the bathroom or the freezer. There may be different brands of Lactic acid that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush Lactic acid down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
