...The magnesium salt of ascorbyl-2-phosphate was found to be equivalent to ascorbic acid in stimulating collagen synthesis in these assays,...

MAP is quite effective depending on what your goals are. Lightning my skin is of no interest. Collagen...more interesting to me.

So how watery your cream liquifed with the MAP? anyone?

Depends how you bind it. And what all you have in the mix....mine is rather a lovely white serum/ lotion.
I bring the pH down to about 6.85 or so as I find it irritating over that. It of course will reduce the shelf life moderately.
At higher concentrations, MAP will recrystalize, but you can get around that with citric acid and then you are back to your pH.
MAP is hydrolyzed in the skin to produce LAA. Skin pH is something like 4.9 to 5.4 , everyone is a bit different.
If you keep the pH 7.0 less problems for shelf life.
MAP is very nice and has been shown to improve hydration in the skin. |
