The Ordinary Ethylated Ascorbic Acid 15% Solution | REVIEW

So I picked up some of the new The Ordinary releases recently, and after using them for the last month I can finally share some full thoughts on them!

First up – the Ethylated Ascorbic Acid 15% Solution.


This was their newest addition to the brand’s line of vitamin C products – bringing their offering up to 8 different Vitamin C formulations! While a few others look interesting to me, I have only ever tried one other – the Ascorbyl Glucoside Solution 12%.

I made the decision not to try their other offerings based on their handy Vitamin C guide.

Based on this guide, there are 3 with High potency and Low stinging. That’s what we want!! (So we know what yo girl is trying next right??)

The active vitamin C in this serum is Ethyl Ascorbic Acid. The molecular structure of EAA helps it to better enter your skin (so that it can actually do the things it claims). Pure ascorbic acid cannot enter into your skin, or dermis, due to its molecular size. It is also much more stable than other derivatives of ascorbic acid.

The main purpose of this ingredient, like MOST vitamin C serums, is to brighten. Which EAA is known to do exceptionally well. In fact, while there is not a lot on the interwebs about this ingredient, the things I can find about it actually call it a “whitening” ingredient.

The only other ingredient in this formulation is Propanediol – which helps with absorption of other ingredients as “has hydrating properties that may leave a smooth, dewy finish.


If you caught my May Likes & Yikes video, you will already know how I feel about this serum. In short – it feels gross on the skin. It’s very oily and sticky, and never really seems to sink in or go away. Considering I like to use my Vitamin C in the morning, this is an awful choice for me in that routine.

I have tried mixing this in with other products during my night time routine. AND – I am seeing a few things on Deciem’s website that EAA is to be used more so at night, or at least their NIOD version. And I don’t mind the feeling as much when used in conjunction with other products.

But unfortunately, it will be a struggle to finish this bottle. And I will not be repurchasing this one from The Ordinary. I have no doubt the ingredients work as promised! I just absolutely hate the texture and oily/stickiness. Now, this may be due to the ingredient Propanediol, as I noted above – it can leave a dewy finish. So I might also look into a serum containing Ethylated Ascorbic Acid – but with a different carrier.

OH, AND DID I MENTION IT IS $18. Yeah – she is up there.


Now I am not in the C-Firma Day Serum club, so I don’t know what it’s like to be truly dedicated to that product.

But I think if you are cool with the sticky gross feeling that product makes the skin feel (at least for me) then I think you would totally love this one! And compared to Drunk Elephant, $18 is a steal.
