Medik8Super C Ferulic - 30 Percent Ethylated L-Ascorbic Acid Vitamin C Serum - With Vitamin E and Ferulic Acid - Targets Signs of Aging - 1.0 oz

I use Skin Ceuticals Vitamin C serum, but it is SO expensive. I tried this and it is pretty close to Skin Ceuticals, but much much less expensive! And very good too

Update: I tried my best to put up with this serum for 1 month. Unfortunately it burned my skin every time I used it and my skin got red and blotchy. I didn’t have that nice vitamin c glow from this serum. This serum smelled like a combination of motor oil and alcohol overtime, I think it’s the smell of the solvent which was the first ingredient,called Methoxymethylbutanol. I looked up this solvent and it can be used as a “paint” solvent. I’m not sure if it’s toxic, but I stopped using it bc I was tired of feeling the burning sensations. I haven’t tried their C Terra one which was also a popular serum. That’s too bad. Because it’s so hard to find a waterless vitamin c serum that does not use propanediol as the main solvent which tends to give that horrible sticky texture. This serum was one of the few that does not use propanediol. So I had to take down 2 more star. I do see great reviews for this product, so if you don’t have ultra sensitive skin, I would say go for it.This vitamin c is one of the potent option that’s not an L-ascorbic acid vitamin serum. The vitamin c serums with L ascorbic acid either oxidizes too fast or irritates my skin due to the low pH formulation.I do have very sensitive skin and had tingling sensations the first few times I applied, then my skin got used to it. It’s a waterless serum but it doesn’t have that horrible silicon or weird sticky feel to it. It does take a while to completely absorb so when you first apply to your skin, it can still have that mild weird sticky sensation then goes away after 15-30 minutes. I don’t have the patience to wait bc I’m a busy mom, so I just layer my Olay sensitive sunscreens SPF 30 and. Mizon BB cream on top of it and just let it absorb on its own with other products I put on the top. I’m not sure if this product would layer well with sunscreens that are 100 % mineral.It smells like motor oil because of the waterless solvent they use, so the motor oil smell might be kinda off putting for some.My other complaint is the dropper makes it hard to apply. If you have the dropper too far away from your face, the minute you take the dropper out of the bottle, the serum will drip all over the place, so you will loose the precious product. So I make sure I bring the bottle next to my face then take the dropper out and it will be on top of my face. So the serum will drop on my face instead of dripping all over my bathroom counter and wasting product.I prefer the Peter Thomas Roth’s vitamin C serum with THD ascorbate bc it’s a lotion consistency with a pump. But the absorption is questionable for the THD ascorbate and may be lower than the 3-o-ethyl ascorbic acid which is what his serum contains. Also the PTR is pricier than this serum. But I’m still going back to the PTR since I like the lotion consistency better than the thick liquid formulation of this vitamin c. I’m still giving it a 4 star (took 1 star off bc the dropper package was a bit inconvenient for me and takes a while to absorb). I would still recommend this vitamin c if you don’t wanna spend a fortune buying the gold standard Skin ceuticals or other less effective vitamin c. This is a great option to try if you can’t tolerate L-ascorbic acid.

Top ingredient is Methoxymethylbutanol which is an industrial cleaning agent. Please do your own research on this ingredient and use this at your own risk. This serum gave me severe irritation. Reached out to the company for safety information on Methoxymethylbutanol and never received a response.

Hi, am using the vitamin C serum on my face and hands to lighten dark spots and very pleased with the results so far

Was expensive but I works great

Product is ok - dropper does not work and could not get a response out of manufacturer.

I did not see the effect on my skin. I’ve used other vitamin c serum like Obagi 20% w immediate results. I thought a 30% vitamin c would be even better but it proved itself wrong. Do not use

The dropper it's defective.I have better and less expensive products that work better for me.I don't see the hype on this product.
