Stand Out Vitamin C Serum

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

    Superior vitamin c product!

    What else needs to be said about a vitamin c product that doesn’t sting, smell bad or turn sensative skin red, absorbs into the skin never pilling under makeup, and most importantly lightening brown spots in a matter of weeks, so effectively that your aesthetician asks what have you changed or added to your routine …

    Now that’s proof of the Amazing Trifecta results!

    Quench for your skin

    I've been using Quench for awhile now, and it's become the one product I genuinely panic about running out of. When I first started, I was skeptical about the "three forms of Vitamin C" claim - felt like marketing speak. But after about six weeks, I noticed my stubborn sunspots were actually fading, and my overall complexion looked brighter and more even.

    What keeps me coming back is how gentle it is. I have sensitive skin and every other Vitamin C serum I've tried has either irritated me or oxidized within weeks. Quench doesn't sting, doesn't smell weird, and a little truly goes a long way - two drops covers my entire face and neck. The texture is perfect - not sticky or greasy, absorbs quickly.

    After two years of consistent use (twice daily), my skin texture is noticeably smoother, my pores look smaller, and I get compliments on my "glow" regularly. The results didn't plateau either - my skin kept improving over time. Yes, it's pricey, but honestly the bottle lasts me 3-4 months, so the cost per use isn't bad.

    If you're on the fence, I'd say give it a solid 8-12 weeks. The results are subtle at first but compound beautifully over time.
