- Magnesium Ascorbyl Phosphate: a stable, water-soluble form of vitamin C with noticeable brightening effects
Vitamin C is an effective antioxidant, brightens the skin tone and reduces signs of ageing. In its pure form, Vitamin C is unstable in water. Magnesium Ascorbyl Phosphate (MAP) is a water-soluble derivative of Vitamin C. It is more stable in water but it is less potent than direct L-Ascorbic Acid. It is compatible with water but higher concentrations cannot be offered in a low-viscosity serum format and requires emulsification to form a cream. This formula is a light cream that offers 10% pure MAP (very high solubilized concentration). Aside from the general benefits of pure Vitamin C, MAP has been shown to offer specific skin brightening benefits, more so than other derivatives of Vitamin C. (Note: some brands offer "powder" formulations that offer up to 15% MAP. Such powders would offer less direct availability of MAP as compared to an emulsion such as this formula which has solubilized the complete 10% concentration of MAP. It is extremely difficult to solubilize higher concentrations of MAP in non-powder formulations.)
The Ordinary's portfolio of Vitamin C includes the following formulations:
Vitamin C Suspension 30% in Silicone
Vitamin C Suspension 23% + HA Spheres 2%
Ascorbyl Glucoside Solution 12%
Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F
Topical Vitamin C offers a wide array of benefits to the skin. However, many forms of Vitamin C and many more formulations of Vitamin C are available commercially with a potential to confuse the audience. We have developed a guide that offers guidance on the formulations of Vitamin C offered under The Ordinary range. It also offers education on Vitamin C itself and on the differences between formulations of Vitamin C at large. Please click here for this guide.
Apply a pea-sized amount to your face in the morning and at night after toners and water-based products.

Yes, we are writing about Vitamin C while our top-selling Vitamin C formula has been (and is) out of stock for over a month. If that doesn't make sense, please refer to our name... but it's coming back really soon. The Ordinary currently offers four Vitamin C formulations: Vitamin C Suspension 23% + HA (C23), Ascorbyl Glucoside Solution 12% (AG12), Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F (ATS20) and Magnesium Ascorbyl Phosphate 10% (MAP10). We are about to introduce two additional Vitamin C formulations to make things worse: Vitamin C 30% Suspension in Silicone (C30) and 100% L-Ascorbic Acid Powder (C100), both really affordable and both coming in July. Pure L-Ascorbic Acid (LAA) formulas (C23/C30/C100) are strongest but they sting as they are super potent. They are suspensions (since LAA is only soluble in water but it’s unstable in water) which means you must use tiny amounts per application to avoid balling up and product waste. C23 avoids silicones to maximize skin utilization of LAA and, as such, can feel a bit gritty despite the very fine mesh of LAA that we use. It can be mixed with hydrators to avoid this grittiness. C30 will include silicones to sting less and feel super smooth with no grittiness, but it will have slightly less skin utilization of LAA (which is why we included more LAA at 30%). C100 can be mixed with other formulas to incorporate LAA as you prefer. What does this all mean? If you want easy, use AG12 (water base) or ATS20 (light oil base). They are less potent but user-friendly to fit any regimen. If you want maximum LAA exposure, use C23 (can mix with other formulas) or C30. If you are an expert, use C100 (mix the powder with other products in your regimen). If skin brightening is your key goal with Vitamin C, use MAP10. Ideally, don’t use LAA formulas at the same time as retinoids or peeling acids; alternate between AM and PM. (PS LAA is soluble only in water but oxidizes quickly in water which is why water formulations of LAA are simply never a good idea regardless of how they are packaged. They turn orange due to oxidation and some products mask this change in colour with added ingredients that are orange.)
