Here's why you should use You Go Girl's Glycerin soap instead of commercial soaps. Glycerin is a humectant, meaning it attracts moisture to your skin. Glycerin is a natural by-product of the soap-making process and while commercial manufacturers remove the glycerin for use in their more profitable lotions and creams. Glycerin is clear, and a lot more moisturizing. People who have dry skin, or even eczema can benefit from using Glycerin soaps.
