Abstract (en)

[origin: WO9516454A1] Papulo-pustules in the skin of patients suffering from various forms of acne, folliculitis and rosacea may be rapidly resolved by a spot therapy which involves topically applying to the exterior surface of the papulo-pustule (pimple) an aqueous solution containing hydrogen peroxide and preferably also at least one fruit acid and/or salicylic acid. A preferred fruit acid is glycolic acid. Both open and closed comedones are also effectively treated by spot therapy with the aqueous solution containing hydrogen peroxide, fruit acid and salicylic acid. The solution preferably contains 3 to 6 weight percent hydrogen peroxide, 2 to 4 weight percent glycolic acid and 2 to 4 weight percent salicylic acid, and is preferably applied 2 to 3 times daily. Treatments continue for 1 to 3 days when directed to papulo-pustules and 7 to 20 days when directed to comedones. The therapy also substantially reduces or avoids hyperpigmentation and scarring after resorption of the papulo-pustules. Application of the hydrogen peroxide solution to the earliest spot (lesion) prevents development of larger papulo-pustules and reduces the possibility of scarring and hyperpigmentation.
