I have been using a different C serum for years and have was hesitant to change, but I am happy that I did. Quench makes my skin smooth and glowing, and I am not experiencing any dryness at all. So far I have had a great experience with KaramMD products!

Fine Lines & Wrinkles, Environmental Damage, Loss of Elasticity , Skin Texture , General AgingRated 4 out of 5 starsLove the product, not the container!
I love using these products, this is now going on my 3rd year of trying the trifecta! I am super happy with my results. The one minor tiff I have is the package they use for Quench. It can be difficult to clean due to becoming crusty, by use over time. It is not a great design for what the product is. But other than that, I love it. -Age 48
