Vitamin C

INCI:

Magnesium Ascorbyl Phosphate

Function in our formulas:

Active

Where does it come from?

Magnesium Ascorbyl Phosphate is synthetically derived from L-Ascorbic Acid which is derived from corn or wheat starch.

What is it?

Magnesium Ascorbyl Phosphate (MAP) is a more stable derivative of Vitamin C than L-Ascorbic Acid (the naturally occuring form of Vitamin C).

How do we use it?

We use MAP as Vitamin C in our formulas as it provides far more stability at more neutral pH levels. L-Ascorbic Acid is effective in a highly acidic environment (pH 3.5) - far too acidic for most other actives - and far too acidic a daily custom cream. MAP allows us to add Vitamin C as an active alongside other beneficial actives at more skin-friendly pH levels (4.5 - 6.0). This also means MAP is suitable for more sensitive skin types as it is much gentler on the skin. We use MAP from 5-15% depending on your skin type, and skin goals.
