Vitamin C Serum

Hands down this is the best Vitamin C serum I have used. I have used the product for over 3 months now and my skin tones are more even and brighter.” - Sari R.

Active & Potent

“Everyone knows Vitamin C is powerful but not all serums are created equal. From first use of this Vitamin C my skin soaked this serum up and I noticed a difference in my skin. ” - Michelle L

Stand Out Vitamin C Serum

“I have tried many different C serums over the years and this is above and beyond the best I have used. I have been using consistently for nearly a year now and notice how smooth and dewy my complexion has become.” Annabel P.

Quench Immediate Results

 “I am truly in love with Quench. I am 69 years old and have never used vitamin C serums. Sunspots have already started to reverse my skin is much clearer and smoother, and just overall healthier looking and feeling.” - Vickie B. 

Best Vitamin C Serum I’ve Tried

This Vitamin C Works

    Vitamin C at it's best!

    So happy to find a vitamin C that is not watery and not LAA! Really like the way it feels. Hope with continued use it will also help with firmness.

    Quench feels so amazing!

    First off, Quench is the perfect name for this product since it immediately feels like it's getting absorbed by my skin as it glides on so smoothly for even distribution. Secondly, I love that it dispenses with a pump so you get just the right amount. Loved this product right from the start.

    Elegant Product

    Previous experience with vitamin C has left my skin irritated. Through research, I discovered KaramMD Quench and was excited to try it. My sensitive skin is loving it, and I will continue to use this in my skin care routine.
