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

“Best Vitamin C Serum I’ve tried. I have tried many, and either didn’t live the texture or smell, or both. A small amount goes a long way, and glides on easily, while still being well-absorbed.” - Susan C. 

This Vitamin C Works

“I really like this Vitamin C. It feels good on my skin is easy to apply, and it works. After using it for several months, it helped tighten the skin of my neck so it does not look wrinkled.” - Judy T.

    Trifecta - GAME CHANGER!

    Quench by Karman MD has been an absolute game changer for my skin. From the first few uses, I noticed a real improvement in my skin’s texture—it feels smoother, softer, and so much more refined. What really blew me away is the radiance. My skin looks healthier, brighter, and genuinely lit from within in a way I hadn’t experienced before. It gives me that fresh, well-rested glow even on days when I’m anything but. Quench doesn’t just hydrate; it transforms how my skin looks and feels. I’ve gotten so many compliments since using it, and it’s officially become a non-negotiable in my routine along with the Trifecta routine!

    gentle strength

    My skin is quite sensitive and doesn't tolerate any harsh products. Therefore other vitamin C serums were often too strong and would leave a redness on my skin. Quench is different. Its formula is mild enough for my skin to tolerate it yet very powerful in the results it produces. Fantastic product!
