This winter has left my skin dry and dull...I added this serum to my routine and it has helped SO much! It has hydrated my skin, yet it doesn't feel greasy and it sinks right in! I will continue to use it even after winter is over!

Best you can buy
I used to work for Kate Somerville and i have tried most of the products with my girlfriend. The Quench Serum was by far one of our favorites, just a little dab goes a looong way. Kate Somerville is the best!!!

This left my skin feeling hydrated but not oily as other products have in the past. My skin felt so soft afterwards. This product had lasting effects as my skin cleared up and my makeup went on easier.

Great Serum
This was my first KS product! I used it with Age Arrest. This serum is so addicting because it feels like a drink of water to the skin. I have very dry skin so I would apply a layer of this and then add some to my cream. This is also good to add to makeup for a glow

Hydrating and Healing
I used the sample of this product and went back for more! It is amazing. I can't believe how quickly it replenishes the skin. I would absolutely recommend it and it is really moisturizing but not in an oily way. Great product that I will definitely be buying again!
