great vitamin C serum for the price! Gone through 2 bottles now (each bottle lasts about 6 months for me, typically just do one pump in the morning every day or so). Pump bottles also keep vitamin c serums more stable than dropper bottles too so I'm happy with that. I have fairly sensitive, combination skin with some breakouts too and have never noticed any worsening when I use this serum. (not sp amb9545 · sephora.com

Took the plunge to splurge on this and give a new vitamin C product a try. I generally don't have great luck with them. This one is gentle and super effective and I like the texture a lot more than other ones I've tried - definitely worth the price for me. I've been using this in conjunction with Good Genes since lactic acid and vitamin C are a great pair, and they have brightened my skin tone imm sarasch · sephora.com
