L-Ascorbic Acid an exfoliator?

I wanted to try to make my own c-serum using LAA but am hesitant after reading from another skincare forum. It said that LAA is so acidic that it exfoliates. If this is true that would mean if used daily it would be like exfoliating daily which is a no-no. This will accelerate aging in the longterm. I read somewhere on this forum that someone experienced seeing more lines after using LAA and was wondering is she was using it too much. I hear that magnesium ascorbyl phosphate (MAP) appears to have the same potential as vitamin c to boost collagen synthesis but is effective in significantly lower concentrations and appears to be a better choice than l-ascorbic acid for people with sensitive skin and those wishing to avoid any concomitant exfoliating effects.

i wish someone could answer because I'm curious now. I know this ingredient is the main ingredient in the new skinceuticals phloretin, which it's supposed to help with wrinkles. There is a web site called futurederma. You may want to try to ask there. Nicki, the blogger, is a med student, very responsive and nice. good luck!

Think of L-Ascorbic Acid as a treatment first and foremost.. It's a beautiful thing, and proven time after time to be at the top of the list for collagen building and it's powerful antioxidant properties..

Keep it at 10 to 15%, which is all your skin needs (or can absorb), and you will reap the rewards, without the irritation.. It will even be just as beneficial if it's only used 3 times per week, because once it has absorbed in your skin, it remains there doing it's thing for up to 72 hours.. You can actually apply a *good* C serum, allow to penetrate for 30 to 60 minutes, wash your face, and you will not wash it away.. Very Happy

MAP + THDA don't measure up to L-AA in my experience or opinion... But that's just me, I'm sure others use and love it.

One serum I made and used a while ago contained 10% L-AA, 7% THDA, 1% vitamin E and .5% Ferulic Acid.. It was very nice, but not *more* effective than L-AA alone..(more moisturizing though!)

Dr. Todorov from smartskincare says the key thing to avoid is any skin irritation. I would say that if it's not making your skin irritated in any way it should be fine. He discusses quite well about MAP being as good or superior to acsorbic acid in collagen synthesis but with out the irritation and exfoliation.
