A top derm-recommended skincare ingredient, you've most likely seen glycolic acid listed on the label of all types of products including toners, serums and creams. "A chemical exfoliant and type of alpha hydroxy acid (AHA), glycolic acid is derived from sugarcane and typically used to improve skin texture and appearance," explains Ellen Marmur, M.D., board-certified dermatologist in New York City and founder of MMSkincare.
While trendy skincare ingredients come and go, this one has withstood the test of time in skincare for good reason: "It works by dissolving dead skin cells and oils without any excess scrubbing," says Dr. Marmur. Plus, "it's antibacterial and helps to reduce hyperpigmentation," adds Azadeh Shirazi, M.D., founder of La Jolla Laser Derm.
Keep scrolling for the best glycolic acid products, which include Good Housekeeping Institute Beauty Lab-tested picks, along with dermatologist and other expert favorites. Plus, how to shop for this top-notch ingredient, the ideal percentages and more.

Pros
- Exfoliates deeply and gently
- Nourishes skin
- Won't irritate
Cons
- Small bottle size
Another Beauty Award winner and GH Seal holder, Mary Kay's gentle serum users both glycolic and polyhydroxy acids to help slough off dead cells within different layers of the skin, leaving skin more radiant. Beauty Lab data evaluation confirmed that while the formula exfoliates, it also helps condition and nourish skin with glycerin. Plus, a study with 104 people found that the product didn’t irritate. It is a small bottle so use sparingly.
Pros
- Brightens and tightens skin
- No irritation
- Reduces the look of fine lines
Cons
- Pricey
Beloved by multiple GH Beauty editors and Lab scientists, Skinbetter's cream combines three top anti-aging ingredients: a retinoid, glycolic acid and lactic acid. The GH Beauty Award winner does what many retinoid products cannot: it reduces the appearance of wrinkles and fine lines with minimal dryness, redness or flaking. "The cream improved my skin texture and added bounce back into my cheeks," says Sabina Wizemann, GH Institute's Beauty Lab Director. "My skin looks brighter and tighter, and I could apply this cream without additional moisturizers (or rich creams) and experience no irritation the next day or after continuous use." While it is a pricey pick, we feel that it's a worthy splurge especially for those that struggle with retinol usage.

The ultimate acid blend, Drunk Elephant's serum "uses glycolic, tartaric, citric and salicylic acid to remove dead skin cells, boost cell turnover, brighten discoloration and unclog pores without causing irritation," says Dr. Shirazi. She recommends it for oily skin "as it helps regulate sebum production," and recommends using it overnight one to two times weekly. You may want to skip if you have dry or sensitive skin as the formula could be too harsh.

AZIMD Skincare's potent pads can be used on the face or body to reduce breakouts and help with discoloration and uneven texture.

"I definitely noticed an improvement with my skin," one reviewer from the brand's site shared. "No blackheads or acne and my skin is more even-toned since I’ve been using this product." Start slowly with usage (one to two times per week) and build up when your skin adjusts, as using too often too quickly could cause a negative skin reaction.

How we choose the best glycolic acid products
Over the years, the Good Housekeeping Institute Beauty Lab has tested thousands of skincare products, including facial peels and exfoliators, both of which often contain glycolic acid. In these two tests, our scientists evaluated a combined total of over 11,000 data points to find the best on the market.
For these tests, the Beauty Lab recruited testers, who evaluated the products on attributes such as ease of use, irritation and perceived results, and used digital imaging to track their changes in skin before and after use. For this story, we chose top-performing products from those tests, as well as top picks from dermatologists and our own Beauty Lab experts and editors.

What to look for when shopping for the best glycolic acid products
There are a couple of factors you should keep in mind for when choosing a product with glycolic acid:
✔️ pH level: "The ideal level is between three and four," says Dr. Marmur. "The lower the level the more active the ingredients are in penetrating your skin."
✔️ Concentration of glycolic acid: "A lower concentration is better for beginners," advises Dr. Marmur.
✔️ Your skin type: "If you’re unsure of how your skin will tolerate glycolic acid, start with a cleanser formulated with it rather than a leave-on product that will be stronger," says Dr. Shirazi. "If you have very sensitive skin, glycolic acid toners or pads that have a blend of ingredients tend to have a lower concentration."
Don't forget to be sun safe when using glycolic acid. "This ingredient can increase skin’s sun sensitivity so limiting sun exposure and applying sunscreen when using glycolic acid is imperative," says GH Beauty Lab's Senior Chemist Danusia Wnek.
What is the best percentage of glycolic acid to use?
"Start low and go slow," says Dr. Shirazi. "Start by applying a lower concentration (5 to 7%) every other day, especially those with sensitive skin, and slowly increase it daily." A cream formulation may be better tolerated at first than a gel or liquid toner, and a cleanser is typically the safest starting point as it is a wash-off product. Dr. Marmur notes that those with more resilient skin may tolerate a concentration of 10% glycolic acid.
"Some also may tolerate twice daily applications at lower glycolic concentrations (2 to 5%)," Dr. Shirazi adds. "An alternative method for using glycolic acid is short contact therapy where the acid is applied to the skin like a mask." You would apply the formula, leave it on for three to five minutes and then rinse it off.
In terms of efficacy, "glycolic acid has been shown to be effective at improving discoloration and skin texture at a 5% concentration," says Danusia Wnek. "However, consumer products can typically contain up to 10% glycolic acid."

What does glycolic acid do?
"Glycolic acid essentially removes the top layers of dead skin cells," says Dr. Marmur. "It does so by breaking the bonds between the outer layer of skin cells (including the dead skin cells) and exfoliating them off, which boosts cell renewal," adds Dr. Shirazi.
"It has been shown to minimize the appearance of photo-aged skin at concentrations found in skincare," says Wnek. In a clinical study, an 8% glycolic acid formula showed significant improvement in overall photo-damaged skin, and tester feedback echoed those results: according to a questionnaire completed after the study, testers noted that the formula significantly improved fine lines, amongst other skin attributes, after 22 weeks. Another study showed that glycolic acid can significantly improve discoloration and skin texture at 5% when compared to a placebo.
How often should you use glycolic acid?
"Frequency of usage really depends on the concentration in the product you are using," says Dr. Marmur. "A higher concentration acid should typically be used once or twice a week, but a very low percentage exfoliant can be used daily. It really depends on your skin type and sensitivity."
