COSRX Pure 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

Non-Sticky Pure Vitamin C
This is a pure Vitamin C and, as a result, it has a smell to it when first applied (as mentioned/complained by many). However, this smell dissipates completely and very quickly. Most brands aren’t pure, thus they don’t have a smell to them. I have used this brand for a couple of years and I like that I get a high percentage of pure vitamin C at a great price, plus it doesn’t leave me sticky like many Vitamin C’s.

Good product, strong smell, some stickiness
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.

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 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!

Good stuff with a good price!
This stuff is so good! It has a slightly woetd smell but my dermatologist said that if your vitamin c serum doesn’t smell like bologna, it isn’t good vitamin c. The smell goes away pretty fast after applying. I just I’ll my breath for a for seconds while I put it on and then it’s gone.My skin looks so healthy and glowing since k started. I am shocked with such good results at su h a good price. You HAVE to keep it refrigerated after opening though!!
