Redness, reactivity and broken barriers need a gentler toolkit, and this is ours: the ISOV azulene line (cream, mist, oil and emulsion), Corthe's Ice Soothing Gel and Dermo Essential Cleansing Powder, and barrier-repair creams for the longer rebuild.

Work in this category is slow by nature. These products support gradual strengthening rather than quick correction, and they suit clients who have reacted badly to actives elsewhere.
