Grandpas soap has been manufactured since the 1800’s so there’s good reason these products are still around. One of them, Thylox soap, is the best topical treatment for acne that we’ve seen our customers use. Many report dramatic improvement in just a few days of use. Thylox contains sulfur which has been traditionally used for skin conditions. This is a great, natural product for various skin conditions and especially acne, where infection is involved.
