"Peach and Lily makes a super nice, relatively affordable Lactic Acid Serum, and it also has a ton of peptides in it. So if you're looking for something to gently exfoliate, but also give you a peptide step in your routine, maybe you're trying to streamline a little bit, highly recommend."

"Another one I have talked about before is from Peach and Lily. This one contains a blend of lactic acid and plant extracts and antioxidants that's very lovely. I use that throughout my pregnancy as my substitute for my topical retinoid. I didn't get irritation. I felt it was very elegant serum that was well tolerated."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Alpha hydroxy acids

Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.

Ceramides

Ceramides are part of the skin's own barrier, and moisturisers built around them have evidence for holding water in and settling the tightness and flaking that come with a damaged barrier.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
