I was wondering what the equivalency is of MAP and L-Ascorbic Acid?

I was looking at a MAP serum online that contains 3% MAP. I was told by the company, that the studies done for MAP, say that 3% MAP is equivalent to 10% L-AA.

Is this an accurate equivalence?

So, instead of using 20% L-AA, one can use 6% MAP, instead, and they are equal in efficacy?

I am confused on this.

Thank you.

There is no firm rule for such equivalency, as it depends on individual biochemistry, including the rate of conversion of MAP to ascorbic acid, etc.
Some people respond to ascorbic acid better than to MAP at concentrations that wold cause equivalent response in others.

And I used to believe in the tooth fairy. If this is true, why does 10 mg of "synthetic" ascorbic acid daily prevent frank scurvy?
