Yay
"It has PHA, which is a gentle exfoliating acid to dissolve the dead skin cells on your face. [...] This one uses lactobionic acid, which is extremely rare when it comes to PHAs, but really, really beneficial for the skin. I think I've only found like maybe one or two other products that have lactobionic acid in them. Really, really good formula. Super gentle on the skin. Definitely great if you're wanting overnight skin hydration with that exfoliation benefit. [...] I've really always loved this serum over the past 3 or 4 years that I've used it. I went through another bottle and will be repurchasing."

"This product is the Oat Milk PHA Serum from Equal Rxn. I love this serum because it's a gentle exfoliating serum utilizing PHA, but unlike a lot of other PHA products on the market, this one has a lactobionic acid, which is a lot more difficult to find. This product is my favorite one from them, if you're looking for an exfoliating experience but also want the hydration as well."
The BEST Serums of 2021!
"The Equal Rxn Oat Milk PHA Serum has a different PHA than mandelic acid, lactobionic acid, which has a bunch of benefits, alongside oat milk for skin soothing benefits. It's a nice consistency, it doesn't feel too heavy on the skin at all, and I'd say definitely good if you lean more towards combination oily skin. It's a simple formula, good for sensitive skin."
Yay
"This is probably the closest dupe you're going to find uh that's still cruelty-free fragrance free things like that"
