What the gurus are saying

Dermatologists found this a straightforward glycolic exfoliant that works well and lasts a long time, though at 33 dollars for glycolic acid alone, the price feels steep. Those with dry skin may want to ease off to once or twice monthly, while others can manage once weekly. One expert notes that anyone prone to cold sores should patch-test first, as the acid can trigger an outbreak, and suggests switching the dropper to a pump for easier use.

"A good drugstore Glycolic Acid Serum by L'Oreal, at 10% glycolic acid. I like that one more specifically for acne-prone skin."

"L'Oreal Glycolic Acid Serum is a gentle exfoliant that can be used depending upon your budget and availability. Exfoliation can be done maximum once in a week if you have dry skin then you can do it once or twice in a month not more than that."

"I use this one by L'Oreal. I always switch the dropper with a pump. If you have cold sores beware it can make your cold sores come out with a vengeance so I would approach very cautiously, but I like to exfoliate my lips with an exfoliating acid and not a physical scrub because I've always found it causes more layers of dead skin that I end up wanting to pick with my mouth and ends up being a bigger disaster."

Glycolic Acid vs. Salicylic Acid: Is it for Your Skin Type & Concern? | Dr. Shereene Idriss

"L'Oreal has their Glycolic Acid Serum at 10 percent. It has a long play time. It is honestly kind of expensive for 33 bucks for just glycolic acid, but it is a beautiful basic Glycolic Acid Serum. I do like it because it goes a long way. I like the texture and it gives your skin a nice sheen. It also has aloe extracts in it which helps a little bit for soothing benefits. I hate the dropper."
