10% Sulfur Paste combines salicylic acid with 10% active sulfur to dry up & medicate spots & acne pimples. The Salicylic acid also has exfoliating properties, allowing dead skin cells to be removed. Balanced with organic camphor to help fight impurities, the product is designed to help prevent the skin from scarring. Malin+ Goetz recommend only using this product on occasion as it is very powerful & over use may dry up the rest of the skin. We are unable to send this product by Airmail.
