Dr. Sturm's THE ULTIMATE STINKY PIMPLE TREATMENT is intended to minimize the appearance of blemishes and begins working from the first application.The formula combines the anti-microbial and sebum-regulating properties of the odour-intensive Shale Oil (hence the name THE ULTIMATE ‘STINKY’ PIMPLE TREATMENT)with an active complex of Tiger Grass, as well as pre- and probiotics, which help soothe and support the skin's own defence mechanisms and rebalance the skin flora.Panthenol and Allantoin reduce irritation and the appearance of redness and Rice Starch has a mattifying effect.
