GLYSOLID works as a skin softener, keeping your skin supple and flexible. There are two active ingredients: Glycerin and Allantoin. GLYSOLID is 50 percent glycerin. It contains no mineral oil or petroleum substitutes. Glycerin is a very hygienically restorative material that works to bond with your own body oils. It's a strong moisturizer and not only softens the skin, but promotes better circulation under the skin. It's also a disinfectant and bacteria fighter. Allantoin is GLYSOLID'S other major active ingredient. Allantoin is an extract from the seedlings of many herbs and is a proven pharmaceutical ingredient. It is especially valued for its astringent, emollient nutritive properties, and is able to soothe and soften skin. Research has shown it to be a cell proliferant, causing faster healing of skin cells while allowing a faster regeneration and replacement of old, worn out skin cells.
