This $10 Skin Care Staple Has A Surprising Second Use — And Reviewers Swear By It

Glycolic acid helps exfoliate, lighten dark spots and clear up the skin...

The hero ingredient in this Ordinary serum is 7% glycolic acid, an alpha hydroxy acid (AHA) with a long history in skin care. San Diego-based board-certified dermatologist Dr. Azadeh Shirazi previously told HuffPost that old skin cells become lazy as we age and pile up, thus preventing fresh, new healthy skin cells from surfacing.“AHAs are water-soluble acids [good] for fading pigmentation, improving texture and tone, softening fine lines, and minimizing pores,” Shirazi said.

And many reviewers seem to agree with this exact Ordinary serum.

“I’ve been using The Ordinary Glycolic Acid 7% Exfoliating Toner about three times a week,” says one user, “and I’m genuinely impressed with how well it handles stubborn, tiny, headless bumps on my face. It leaves my skin feeling smooth, refreshed, and visibly brighter without being harsh or irritating.”

“The best thing I have included in my skincare routine,” says another reviewer. “Makes my skin clean, clear and bright. All my hyperpigmentation is gone. My skin loves this product, and it’s definitely worth the cost.”
