It is a silky serum, a little goes a long way - normally I would use 2 or 3 pumps with a serum (not a Kate Sommerville product as this is the first serum I have used in this range), but this one really does only require one pump as they say. So I am expecting it will last for a long time. Makes my skin look very hydrated, and it feels incredibly smooth and soft. It has been almost 2 weeks, and I love it. Highly recommend this product. I have combination skin so I was worried that maybe it would be too heavy and I should have gone with the oil free version, but I have not had any problems, it is quite light. If you skin is more oily that combination I would think the oil free serum would be best. But this is great if you do have dry areas - I certainly don't any more!
When I purchased the Quench, I assumed it would be like most other products advertised and is never as good as said. But not the case with Quench...I've re-ordered it many times as I can't be with out it or the Exfolikate. Huge fan of both. They have made such a difference in my skin.
