Sastid Soap is a combination of precipitated sulphur and salicylic acid in a richly lathering base. Sulfur is anti-bacterial and anti-fungal all excellent for the treatment of various skin disorders such as acne, dermatitis, fungus, psoriasis and oily skin. Sulfur and salicylic acid soaps are effective in initially clearing tinea versicolor but the relapse rates are quite high. Better results may be achieved if the application regimen is modified, if these soaps are used as maintenance or combination therapy or if these soaps alone are used on a regular basis instead of other soaps. Direction for use: For best results use warm water and allow 60 seconds before rinse, this allows the micronized sulfur to penetrate deep into the pores killing all bacteria and fungus on contact while at the same time it will shed dead skin cells, reduce inflammation and redness. Use under medical supervision.
