What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

Glycolic Acid: Uses, Safety & Side Effects

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Reviewed July 2026 ·

The bottom line

Glycolic acid is a topical alpha-hydroxy acid (AHA) used mainly to exfoliate the skin, smooth texture, and improve appearance. It is not a dietary supplement you swallow—it is applied to the skin and is generally well tolerated, though it can cause irritation and sun sensitivity. Always follow product directions and use sunscreen, and talk to a pharmacist or dermatologist if you have sensitive skin.

Part used: Not applicable (a chemically produced or naturally sourced acid)
Common forms: Topical creams, gels, serums, cleansers, chemical peels, and lotions

People commonly use it for

Acne
Anti-aging and fine lines
Uneven skin tone and dark spots
Skin exfoliation
Rough or dry skin texture

Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.

Overview

Glycolic acid is a type of alpha-hydroxy acid (AHA). It is the smallest AHA molecule, which allows it to pass easily into the upper layers of the skin. It is naturally found in small amounts in sugarcane and some fruits, but most glycolic acid used in skincare products is made in a lab to ensure a consistent strength.

Unlike many items on this site, glycolic acid is not an oral dietary supplement. It is used on the skin in products such as cleansers, lotions, serums, and professional chemical peels. People use it to exfoliate dead skin cells and to help the skin look smoother and brighter.

How it works

Glycolic acid works mainly by loosening the bonds that hold dead skin cells together on the surface of the skin. This helps old cells shed more easily, revealing fresher skin underneath and giving a smoother, brighter look.

Over time, regular use may also encourage the skin to make more collagen and improve moisture retention, which is why it is studied for fine lines and texture. Because it is a very small molecule, it penetrates the skin more readily than some other acids, which is part of why it can be both effective and irritating.
