Perfect for troublesome acne
It definitely does smell like spam LOL. But thatâs ok because I find once you shake the bottle and apply it at night, you canât smell it anymore. It also helped to take most of my big acne away! I use it on top of a rice toner at night with some moisturizer and it has helped more than my medication for acne. Highly recommend!! But def wear sunscreen every morning after using it. I have acne prone skin thatâs super oily and sometimes dry. It worked well to reduce oil as well. I still need something else to completely get rid of the small bumps and white heads but Iâll be rebuying this too.

real and natural
Yes the color, smell is a little weird but this is the real stuff that actually works not some processed junk.

Could cause acne
I’ve been a huge fan of Cosrx products. I originally had used the lower strength of vitamin c and upgraded to this one a few months back. I feel that it does work in terms of discoloration, but for some reason this one makes me break out more than other vitamin c products I’ve used. I’m going to finish up what I have left of this bottle but I think I’ll go back to the lower strength. My only complaint with the Cosrx vitamin c is how small the bottles are. It could be because vitamin c doesn’t last long in terms of potency once opened, but it’s a bit pricey for such a small bottle. You definitely have to keep it in the fridge and the smell is strange and not very pleasant but goes away shortly after application. I have not noticed any stinging or irritation from this higher strength vitamin c, but like I said, I have noticed acne break outs happening a bit more than before. My recommendation…give it a shot if you’ve already used the lower strength and feel you need more potency, but beware of potential break outs.

Happy with it, very good formula
First time with this brand, but using Vit C serum for years.So far one of my favorites in the range of price. Smells uncomfortable fishy but that is the Vit C normal smell, after some seconds over the skin the smell is gone, and personally prefer this than any extra essence. The oil is pretty thin and absorbs immediately. Haven’t had any reactions but I have quite of time with this VitC concentration. I like how my skin looks, give me a glossy renewed look every morning. Any result with dark spots or fine lines, but I realized that is normal aging and nothing to do with it lol, anyway my skin looks healthy and younger for my age. Totally happy with this brand in my second week of use.Update: one month of use and still love it!

Did this make me sick?
After showering on a Friday evening, I applied the serum to my face. The smell was absolutely disgusting, but I was prepared for that having read the reviews. I had no negative skin reactions. A couple of hours later I started to get a headache. I took some ibuprofen, put the heating pad on my head, and went to sleep. I woke up at 3am with a terrible headache and I felt nauseous. I want to note that I get frequent migraines and that this was not a migraine headache. It was a painful tightness all around the top of my head. Also, I realized that the heat from the heating pad was reactivating the smell of the serum on my face, which was really gross. When I finally tried to get up and move around at 7am it was awful. I felt like I had the stomach flu. Sweating, shaking, nauseous. And then I threw up. I really did think I was sick and didnât even consider the serum until a few hours later. I talked to my sister and mentioned my thoughts about the serum. She suggested that I take a long hot shower to try and get it all off of me and to change my bedding. So I did, and by the end of Saturday I was feeling not 100% but so much better. I havenât seen any other reviews that mention this type of reaction. I tried googling it too and found nothing, so obviously this could be some kind of weird coincidence that I got sick for a short time while trying to use this product. Either way, Iâm too scared to try it again. The smell alone might make me sick anyway. Good luck!

Strong Smell & Poor Packaging
Iâve only been using this serum for a week, so I canât speak to the results yet but the smell is awful. It seriously reminds me of canned dog food (beef kind), and itâs hard to get past.Also, the packaging isnât great.The first bottle arrived completely leaked and had to be returned. The replacement came quickly, but it still had a slight leak. Not sealed well, which is disappointing for a serum that oxidizes easily.

Seeing Results
Iâve seen a lot of improvement in my skins texture and tone over the past 3 months. My skin Is much softer and my freckles and dark spots have become less noticeable. The serum is oily and spreads easily. It does have somewhat of an odor (like bread). I think for the price itâs great product.
Cute i really like it –
its kinda of sticky, but it does good to my skin. I dont rub it but just tap it to my face, every other day.

I have been using the COSRX Pure Vitamin C Serum with Vitamin E for a while now and I really love it. At first, I noticed it has a slightly weird smell. It is not unpleasant but definitely unique compared to other serums I have tried. Once you get used to the smell, it is no longer a problem.What I really like is how it feels on the skin. The texture is very lightweight and it absorbs quickly without leaving any sticky or greasy feeling. It gives my skin a fresh and real sensation as if it is doing something beneficial deep down rather than just sitting on the surface.Since using this serum regularly I have noticed that my skin looks brighter and more even toned. It feels softer and smoother. The added Vitamin E helps with hydration and nourishes my skin. I also appreciate that it does not irritate my skin even though it can be sensitive sometimes so it is gentle yet effective.Overall despite the odd smell at first the performance of this serum makes it totally worth it. It feels like a high quality product that works well and I would definitely recommend it to anyone looking to improve their skincare routine with a Vitamin C serum that actually delivers results.
