This product is life changing. I use twice daily (1 tube for 2 weeks) and my skin looks better than it did 20 years ago. It's brighter and more luminous and my acne is completely gone. (so unfair to have both acne and fine lines) I don't need foundation at all when I am using this. I get a ton of compliments both on my tiktok (no filter!) and out and about from random strangers wanting to know wha JMSmith · clinique.com.my

I have used Obagi Vitamin C 20% for fifteen years and I wouldn’t miss one morning I am 71 years old. And as you can see, no wrinkles. I owe this to Dr John Mallen plastic surgeon who I introduced me to Obagi years ago Thank you Janet L. · obagi.com
