Vitamin C comes in different derivatives and Sodium Ascorbyl Phosphate is one of them. 


For the fact that L-ascorbic acid (which is the purest form of vitamin C) is unstable and may not be suitable for all skin types, led to the invention of other forms of vitamin C. 

Vitamin C derivatives are formulated with two things in mind. — stability and non-irritant-purpose.

L-ascorbic acid form of vitamin C is notorious for being unstable (can easily oxidize) and increases skin sensitivity due to its acidic nature, which offers skin exfoliating  potentials and this effect may not be suitable for all skin types, especially for people with senstive skin. 

The invention of vitamin C derivatives is to tackle the issue of instability and lessen possible irritation occurrence as vitamin C derivatives are non-exfoliant. This is to make the new generation vitamin C’s pretty stable and used by all skin types without complications. Keep reading to learn more about Sodium ascorbyl phosphate form of vitamin C. 

What Is Sodium Ascorbyl Phosphate?

Sodium ascorbyl phosphate is a very stable and water-soluble form of vitamin C, which is very gentle and mild on the skin, causes no skin irritations, and converts to ascorbic acid when it’s absorbed into the skin. 

Sodium ascorbyl phosphate is produced by direct phosphorylation of ascorbic acid sodium salt where l-ascorbic acid is suspended in an oxygenated, non-hydroxylic solvent together with sodium and then treated with a phosphorylating agent.

Sodium ascorbyl phosphate ultimately converts into ascorbic acid once it gets absorbed in the skin, [1]

this conversion process is what makes it less active and, yes, also less effective than L-ascorbic acid (this process also applies to all forms of vitamin C derivatives). But hey, this form of vitamin C is very effective and very potent in combating age spots, fine lines, free radicals. It also brightens the skin, making it glow, shine and youthful.

The skin benefits of Sodium ascorbyl phosphate will be further explained below. 

Skin Benefits Of Sodium Ascorbyl Phosphate.

Just like all forms of vitamin C, Sodium ascorbyl phosphate offers same potentials to the skin, except for the fact that it isn’t as potent as pure form of vitamin C (L-ascorbic acid). 

Just like all forms of vitamin C, Sodium Ascorbyl Phosphate:

Fights Free Radicals.

Sodium ascorbyl phosphate works to combat the effects of UV damage by scavenging the free radicals that cause DNA changes and lead to signs of photoaging [2]. Exposure to sun and pollution creates free radicals in the skin, which ultimately can cause things such as spots, wrinkles, and sagging. But that doesn’t mean it should replace your sunscreen, always wear your sunscreen before exploring your outdoor activities. And also note that vitamin C helps potentiates the effect of your sunscreen.

Helps Fight Acne. 

Sodium ascorbyl phosphate possesses anti-inflammatory potentials which makes it effective in getting rid of acne. As proven in a research study, sodium ascorbyl phosphate shows in vitro and in vivo efficacy in the prevention and treatment of acne vulgaris. Coupled with the fact that it’s less irritating than other forms of the vitamin C, makes it a good pick for those prone to breakouts.

Enhances Collagen Production.

Collagen gives your skin its firm structure and texture, when collagen production level depletes, it becomes a problem — which gives room for skin aging-signs like wrinkles, fine lines and saggy skin. Sodium ascorbyl phosphate form of vitamin C helps promotes collagen production by enhancing fibroblast (the cell that creates collagen) to produce more collagen which in turn promotes skin elasticity and firmness [3].

Brightens Discoloration.

Sodium ascorbyl phosphate not only enhances your skin’s appearance by brightening your complexion but also target and fades off hyperpigmentation such as brown spots, dark spots, sun spots and even acne scars by blocking the pathway of pigment synthesis.

How To Use Sodium Ascorbyl Phosphate.

Sodium ascorbyl phosphate can be found in over-the-counter water-based products such as serums, toners and moisturizers, but mostly found in serums. To get the most of sodium ascorbyl phosphate, ensure to go for products in serums with higher concentration (15-20%) considering the fact it’s a non-acidic, which makes it have no skin exfoliating or sensitization potentials — making it suitable for people with senstive skin. It’s also safe to use in conjunction with skin care actives, such as alpha and beta hydroxy acids, retinols, and SPF.

Apply both morning (AM) and Evening (PM) for more effective results. Vitamin C helps fights environmental aggressors, fend-off free radicals and keeps the skin protected, it also potentiates the efficacy of your sunscreen to further protect your skin from UVA and UVB rays of the sun. 

Side Effects Of Sodium Ascorbyl Phosphate.

While L-ascorbic acid form of vitamin C notoriously irritates the skin, sodium ascorbyl phosphate is a great option for those who can’t tolerate it, but still, it is an active ingredient, so there is some potential for irritation, particularly for those whose skin is on the super sensitive side. Therefore endeavor to do a patch test prior to commencing product application and don’t forget to always wear your sunscreen.
