I have used Vitamin C serum before but never this brand. I had a severe reaction to it. My entire face was swollen and red. I ended up at the doctor for a steroid shot. The swelling lasted for 2 days even after receiving the shot. Once the swelling and redness finally went away, I was left with scaly dry skin for another week or so. It took forever to get my skin back to normal. Be careful with this product.

I’m was so unhappy with this product.  Very sticky, dries like an egg wash on your face.  I wish I had kept the packaging so I could return it.  An expensive mistake.

This serum is amazing! Better than any high end serum I have tried. It visibly has made my skin more even and glowy. Lays down a bit tacky which I love under make up! Will definitely repurchase (again and again !)

Tried this and ended up at my doctor's with an RX for steroid for red blotchy skin and swollen eyes. Will not buy again. I had tried before but bought in UK and was fine. This time bought in USA and ingredients must be different.

I truly love the feel of No7 Vitamin C serum , it just sinks into your skin with no greasy or oily feeling at all . Leaves my skin feeling amazing with a subtle glow . Highly recommended.

I really enjoyed using this serum. I mixed it with both my day and night moisturizers, and I think it may have brightened my complexion a little bit.

I was looking for a great vitamin c serum for daily use with my rose quartz face roller and this is it. My skin is brighter and more moisturized

I LOVE this serum- it makes my skin so glowy and sets in quickly. It's been such a nice part of my morning and evening skincare routines.

I'm no stranger to Vitamin C serums. This has a great price point, a pleasant citrus smell, contains 15% vitamin C, and comes in an easy to use dropper form. It should be exactly what I'm looking for, but it fell short in many ways. The instructions say to use 3-4 drops per application, which is much more product than I use with my typical serums. Upon application, the product dries very sticky, but this was easily fixed by applying moisturizer over it to smooth out the stickiness. It reacted well with my moisturizer and my makeup until the end of the day when it started to bead up in sticky glue-like beads. Upon further inspection I found the main active ingredient is 3-O-ethyl ascorbic acid. While this form of Vitamin C has more shelf stability than L-ascorbic acid, I much prefer L-ascorbic acid because it is more efficacious. Overall, I felt that this serum left much to be desired.

Wow my skin is so blotchy and dry. Mostly itchy. I just want to scrub my face. I have a little bit of sensitive skin but never a reaction like this. Be cautious when using.
