Forty-five minutes in four stages: cleansing, gentle exfoliation, a ghassoul mask, the clay of the Middle Atlas, then argan oil and Damask rose water.
Ghassoul absorbs sebum without stripping, which makes it bearable even on sensitive skin. The argan oil is applied pure: it is the one step where nothing is diluted.
The complexion is brighter on leaving, but the real effect settles over two or three days. Avoid make-up for a few hours afterwards.
