[REVIEW] The Ordinary Magnesium Ascorbyl Phosphate 10%

The Ordinary Magnesium Ascorbyl Phosphate 10% MAP Review:

Just as any typical Asian girl, I’ve always tried to brighten up my skin tone and keep the hyperpigmentations stay away as fast as possible. To meet the demand, vitamin C serum is produced. Vitamin C has been proven to offer numerous benefits, not only does it help improve your skin tone but it also do well in enhancing your skin natural barrier.

My first ever vitamin C serum is the L-Ascorbic Acid derivative, which is known for its quick effect on your skin and many requirements in terms of keeping it because of the unstability to the normal environment. After using it for a while, I realized that no matter how well I keep it in the fridge and try to use it up as fast as possible, it always oxidized when there was plenty left in the bottle and I had to throw it all away. What I need now is some kind of vitamin C derivatives that is stable in structure, easy to store and yet proves good efficacy. The Ordinary comes up and offers this baby, which completes all my requirements.


Help in improve visibly targets:

– Dullness, Uneven tone, Sign of Age

– 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.

The Ordinary Magnesium Ascorbyl Phosphate 10% Review:

A quick refresh on the main ingredient of this goody: 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 10% is a high concentration.

Hence, The Ordinary believes that it is best to offer the product in cream form. In this product, you will be treated under a light cream that contains 10% pure MAP (very high solubilized concentration).

I have used this guy for 3 weeks from now. I have to tell you that this guy works. Having recovered from my quite severe breakout (due to the changing weather), I’ve tons of pigmentations and scars to deal with. This product has accompanied with me throughout the journey and has done me wonders. Below is my experience based on 3 main points:

The Ordinary Magnesium Ascorbyl Phosphate 10% Review

First impression: I will deliberate my opinion on 2 main aspects: product texture and scent.

Product texture: You might step back a bit when realizing that this product contains silicone. However, in my own experience, that would not be a big problem. As mentioned above, it would brings greater efficacy in the form of cream. It will not cause any breakouts on our skin. The proof is that my skin is both oily and acne-prone, yet my skin is loving it! The texture is light, easy to blend and well-absorbed into the skin.

Scent: The Ordinary has sweared by only adding what you need in their products and leave out all the unnecessary additives. That’s why this product has no comfort scent. Having been familiar with scented products, which are known for their lovable scent thanks to the “fragrance” term in the ingredient list, I was a little bit uncomfortable of the “silicony” scent in the first couple of times applying this product. Now I am used to its true scent and actually I like it now!  

Usage/ how I combine this product into my routine: Since it is the cream-based, I apply it last in my night routine. My daily routine would go like this: Micellar water – Cleanser – Toner – Lotion – Serum – Aloe gel – The Ordinary Magnesium Ascorbyl Phosphate 10%.

The same routine goes on for the morning, but without the micellar water and add sunscreen as the last stage. The product leaves a silky touch at first glance. Approximately 2-3 minutes later, it will be absorbed fully into your skin and leaves no greasy feeling. However, you may expect product piling up and this is discussed more thoroughly in the last point.

Its efficacy: Since it is vitamin C derivative. I did not expect much, however, I notice some changes in my skin look. The most notable change is that the fine lines, especially at the intersection of the cheeks and the lips, have slightly disappeared. Moreover, as I’ve mentioned before, I am having some pigmentations and they are fading away ever since I used this product. I would say that The Ordinary Magnesium Ascorbyl Phosphate 10% did nothing to my scars, or just because I have not been able to notice yet.

The Ordinary Magnesium Ascorbyl Phosphate 10% Review

Tips upon application: This product may pills or balls up on your face! Once in a while I notice that everything is flaking off. This is not what I want. It proves that all of the products I’ve been applying is now falling out. Why is this happening? After some researches, I realized that, “ OH! This comes in silicone-based. This is the reason.” Here are a few tricks that I’ve applied to myself and they work.

  • First:  wait for the previous skincare layer to absorb before applying The Ordinary Magnesium Ascorbyl Phosphate 10%.
  • Second: if the first trick does not work, it may suggest that the products cannot come together. Hence, you have no choice but to switch the products so that they will be compatible to one another.

I used the first trick and it works, a hugeee relief since I do not have to do more researches and get another new product. *phew*

  1. Remember the notice “not to use vitamin C together with niacinamide”? The reason behind this is that the vitamin C might turn to brownish texture, which does not look good at all. The MAP 10% is different. It can be safely combined with Niacinamide. Yey! I’ve tried MAP 10% and  Niacinamide 10%. They go perfectly well with each other.
  2. How much is enough? Just like ordinary cream-based products, I follow applying a pea-sized for my whole face, twice a day. Therefore, 2 pea-sized of product to give you an even skin tone.

I would totally repurchase this, with all the good benefits and pros that it offers.
