Stop Spot is directly derived from Guerlain's cult treatment, Crème Camphréa, created in 1870. Concentrated in purifying camphor, sebum-regulating zinc and micro-exfoliating salicylic acid, this treatment effectively targets redness and imperfections. Applied topically, it takes instant action to regulate excess sebum, soothe irritation and reduce redness. Its shade with optimal coverage effectively conceals all imperfections.
