Daily Glamming Essential!
I can't say enough about this dreamy, skin plumping fluid. I love mixing it with my moisturizer for an extra dewy look or using on its own as a fabulous serum. It is not greasy at all but had terrific "slip" which makes applying makeup or additional products a breeze. I seriously won't go without this dream product.

Must have!
Is there anything kate somerville can't do right ? When I first tried this serum it knocked my socks off. I was so impressed as to how my skin looked after putting this on. Love love love
My face was so luminous and hydrated.

Perfect serum I've used!!
I love Kate's product so much, this one fits me perfectly with the oil free moisturizer! It's not oily, only a small amount can cover the whole face. I have this one, my face is not oily anymore after the whole day in summer, nor dry on the 10+ hours international airplane! Love it!!
