Cabin air is drier than most deserts. New water confuses your skin before you notice. And sun-stressed skin needs calm, not a scrub. 4 things I find myself saying to friends every summer.

Most serums are 70 to 80% water, held together with alcohol and preservatives your skin can do without. I want to show you why a waterless serum behaves so differently.

Every week, people write to ask whether waterless skincare will calm their skin, how soon they will see a change, why the serum is the colour it is. I have gathered the questions we are asked most, with my founder answers, in one place.
