Please doublecheck my concoction:
-120 ml cerave cream
-3-5 gr Skinactives MAP
Will result in 3-5% strength. I asked Hannah Sivak that her website suggests 10 gr=10%. I sensed she doesnt have any idea or just doesnt want to share.
So how watery your cream liquifed with the MAP? anyone?
Also
Anybody uses NOW Ascorbic acid. Despite my bottle being 2 years past the due date, this stuff is stronger than any other LAA i used so far. I used:
-Smidgeon spoon
-1.4 ml water = 0.25 tsp |

| If you read the literature about MAP studies most of them were done with MAP used 10-15% concentration. MAP does not exfoliate and does not help with pigmentation in low concentrations. MAP is also a salt and will liquify a cream, which is why its most often found in serums. I use it in a serum in 10% concentration and have not seen any dramatic improvements with its use. Its very expensive and I do question its efficacy. |

...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.

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. |

| I agree. MAP is wonderful and my skin really really loves it. After it absorbs it leaves an amazing glow on my skin. It's a great alternative to LAA if your skin is sensitive to that (like mine is). |
