I am using the 20% vitamin c and I do notice it plumps and smooths my skin. I have a few acne spots and it’s been about a month, no improvement yet. It feels a little sticky at first but sinks in and feels fine. I am 55 with oily and dry spots on my face, occasionally breakout.
I’m on my second bottle of Obagi professional strength vitamin C 15%. I’ve used many in the past years and this one is by far my favorite 😻 I can’t wait to step up to the 20% after I finish my current 15% Obagi professional vitamin c serum!
My shipment arrived quickly and with some bonus goodies inside (like crazy big samples of expensive products.) Serum was in perfect condition. Will purchase from this company again!!
I have oily and dull skin, I purchased serum C 20% from SkincareEssentials and they sent OMG so much samples for other products how great services they have.. thank you for such a great deals and products and wonderful services. I honestly recommend obagi serum C 20%.
I have very sensitive skin and have used Obagi products in the past. I decided I wanted to try the Vitamin C serum again and purchased the Vitamin C 20. Sadly after one application, it appeared to dry my skin (several dry patches). Perhaps I should have started with a lower concentration (10) and worked my way up to achieve the results all of the other reviewers have received. Because of the price, I am unable to purchase the 10 concentrate at this time.
Other than that, I love all Obagi products and ZO Skin Health products.
