Does Vitamin C Exfoliate

[Product Question] Does Vitamin C have the same exfoliant abilities as AHA?

I read that the L-AA form of Vitamin C has a low enough pH that it is also considered an exfoliant in its own right.

My question is does L-AA as an exfoliant act in the same or similar manner as an AHA exfoliant? If not, how do they differ in their mechanisms of action?

I've also heard and read the L-AA is the only form of Vitamin C that exfoliates skin. I don't know what the mechanism is, but I've definitely read this several times.

level 2

yes, this is what I read as well.

Nope, vitamin C is an antioxidant and AHA is an exfoliant. Being an acid doesn't make an ingredient an exfoliant.

Lots of ingredients have multiple properties, it is not as simple as pigeonholing. If a product is more acidic than skin pH it will exfoliate to a greater or lesser extent. I have overexfoliated with L-AA.

No. If you use a very large amount (like a dropper full) twice a day at a high percentage, yes, you'll notice exfoliation- but that's way too much L-AA and undesirable.

It doesn't need to exfoliate for it to be effective.

Any true acid can exfoliate if the finished product is a low pH, ie. it is not buffered. L-ascorbic acid doesn't have all the same properties as AHAs tho and vice versa. I couldn't tell you the specific mechanism of action, but not really sure why you would need that anyway.
