COSRXPure Vitamin C 23% Serum with Vitamin E & Hyaluronic Acid, Brightening & Hydrating Facial Serum for Fine Lines, Uneven Skin Tone & Dull Skin, 0.7oz/20g, Korean Skin Care

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!

I’ve 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 it’s great product.

I love their products and use several of them so I figured I'd like this, too. It works well and does what it says but the smell is too much for me. It smells like Vitamin C, woodsy and earthy and it's a very strong smell. Some people may like it. I don't care for it. Also, it is sticky and takes a while to dry down. I used a small amount as some reviewers suggested and gave it plenty of time to dry. It did improve but I still felt stickiness . Some people may not mind but I don't like that feeling on my face. So it's really about personal preferences on the smell and slight stickiness. That's why I gave it four stars. Otherwise, it's a good product and delivers results. I'll finish the bottle and then go back to CerVe vitamin C serum.

My skin feels amazing, used it just a couple of times and I can already see a difference. The only thing I did not like was the smells, smells awful but seems to be working great so far.

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 didn’t 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 haven’t 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, I’m too scared to try it again. The smell alone might make me sick anyway. Good luck!

ANOTHER UPDATED POST: bought my second bottle. Still smells awful, but I was excited given that the first bottle helped my skin. The first time, the box did not have any ingredients, and I could not find the information online. I specifically did not want to use product with tocopherol. Well, this time, the box did have ingredients, and I am delighted to see that the vitamin e is sourced tocotrinels, but my excitement was short lived as I saw tocopherol was on the list as well (see photo). I will still use this since I opened the bottle, but I won’t be buying again. From four stars to three.UPDATED POST: This still smells awful, but I must be getting used to the smell, or ignoring the smell because the product has made my skin smoother and more radiant. I just finished my first bottle and contemplating if I want to buy another. Bumping this product from two stars to four stars.ORIGINAL POST: This is the worst smelling vitamin C serum ever. I dont want one that is strong in fragrance, but this literally smells like gas I feel like I am getting drunk while smelling the scent when I use it on my face. This is awful awful awful. I can’t get past the smell to see the results. The smell does not disappear, despite what other reviewers claim. I can still smell the serum an hour after initial use.

I don’t have any problems besides the smell. A very odd smell I had to come look at reviews to make sure it didn’t spoil…IDK ….. I just didn’t understand it. But the product itself is good and the smell is tolerable.

Friends, be grateful for this high quality Vit C serum. Of the countless Vit C’s I’ve tried, this smells, feels and produces results similar to the coveted Skin Ceuticals C serum, but without the price! Keep it in the fridge and use it daily. You’ll agree.
