The Ordinary – Magnesium Ascorbyl Phosphate 10% (avoid – poor formula?)

The Ordinary - Magnesium Ascorbyl Phosphate



The Ordinary’s Magnesium Ascorbyl Phosphate is a bit of an odd product it’s not really a moisturiser, more of a cream and forms part of The Ordinary removing pigmentation regime and being listed in the hyperpigmentation regime I had high hopes for this product.

Magnesium Ascorbyl Phosphate is a water-soluble (with better stability) derivative form vitamin C. The purer forms of vitamin C (ascorbic acid/l-ascorbic acid) are notoriously unstable. They can be rendered useless quickly if not looked after properly.

Full disclosure; I like a number of The Ordinary’s products but I do find them a little hit and miss.

The Ordinary’s Magnesium Ascorbyl Phosphate product claims

The Ordinary’s Magnesium Ascorbyl Phosphate is supposed to help with brightening the complexion, help with hyperpigmentation and is an anti-oxidant which should help with those pesky free radicals (which is such a feature of modern-day life).

After using this for some time, I found this did (to some level) help with the general brightening of my overall complexion. 

However, (and this is a big one) the product had little effect on hyperpigmentation I don’t think I saw any improvement at all. Overall, I found the Magnesium Ascorbyl Phosphate quite a disappointing product.

My final thoughts

I did not like the texture of this product; it felt like it was too heavy in silicone. Silicone is used in cosmetics to give products a ‘slip’ feeling so that it smooths onto the skin nicely. When applied, the product almost felt greasy, without the grease if that makes sense?

Typically with pure forms of vitamin C, you may experience tingling when it is first applied, this is not the case with this product. It felt very neutral like I was applying a regular moisturiser on – I am not sure if it is because I am used to different forms of vitamin c, or just the product doesn’t behave in the same manner.

I also found this product very difficult to use; it tends to pill very easily! Pilling is usually caused by using too many products, layering products too quickly, using ingredients that do not work together or applying too much of the product that likes to pill. I tried a variety of ways to get this to work (I don’t like giving up easily!)

The only way I could get this to work was by using a pea-sized amount and pressing the product into the skin helped to prevent it pilling. In essence, this overall added to the application time, and there are many other products on the market which are not so finicky.

Once on the skin, the product feels slightly occlusive. I found that my moisturiser would sometimes just sit on top and not absorb. I tried this with several different moisturisers and had the same problem. So, by the time I add sunscreen, I looked oily! 

However, on the plus side, the product does leave a subtle glow to the skin.

At the time of writing you can by a 30ml tube for £7.80 ( or from The Ordinary’s website.


0.5 star rating

I was very unimpressed with this item, for the lack of results and the difficulty in using. Given that the market is oversaturated with similar vitamin c products, I would not repurchase this product. 

I honestly cannot think of a skin type that might benefit from this product as it generally feels like a bad formula. I honestly gave it the best shot I could, but I just could not get this product to work correctly.
