"Glycolic acid has the smallest molecular size of all AHAs. This means it doesn't just exfoliate, it rushes into the skin. In darker skin tones, this rapid penetration causes a shock response. The nerve endings detect a threat, inflammation spikes, and melanocytes drop pigment. I've seen countless patients darken their melasma because they were over exfoliating with glycolic acid. The fix is to switch to lactic acid or mandelic acid or even phytic acid. These are larger molecules, they exfoliate slowly and politely without waking up your pigment cells."

"Avoid glycolic acid if you have skin of color. Glycolic acid has a tiny molecular weight and it can fly through the skin, burn the skin, lead to hot spots."

"I'm getting collagen stimulating from my retinol, I'm also getting it from the glycolic acid, I'm also getting it from the peptide serums that I'm using on a consistent basis that are targeted towards firming the skin and stimulating collagen."

"Alpha hydroxy acids like glycolic acid may be effective at softening and flattening keratosis. Don't expect these creams however to take them away, but they can help in softening and flattening them out and perhaps making them more amenable to treatments."

"If your skin is either a combination or oily or you suffer from hyperpigmentation glycolic acid is going to be your jam. Exfoliating acids in my opinion are best used at bedtime because your exfoliating acid is going to take off that top layer of the skin, and the new layer skin that's underneath is very prone to sunburn and sensitivity so making sure that it's properly protected especially with your sunscreen in morning it's going to be extremely important."

"You absolutely want to avoid other acids. Something like glycolic acid or salicylic acid you absolutely want to avoid because even though this says AHA BHA, AHAs are things like glycolic acid and BHA is salicylic acid, so you don't want to be using this and then use a salicylic acid cream or use a salicylic acid moisturizer and totally double up. This is potent and unless you've tested it, unless your skin is really resilient, or unless a professional has recommended it directly to you, you don't want to do more than you have to. If you don't know that BHA is the same as salicylic acid or that tartaric acid or mandelic acid is an AHA, you might use this and think oh I'm going to use a salicylic acid moisturizer, I'm going to use a glycolic acid toner, no no no, we don't want to double up on acids. This is a lot and we don't want to burn our skin off more than intended."
