Glycerin, or glycerol, is derived from plantbased oils. It is concidered nontoxic and environmentally friendly. Unlike many other soaps, pure glycerin soap is all-natural. This makes it vegan friendly and a great option for people with sensitive skin. Glycerin can help lock in your skin´s natural moisture and prevent over-drying, bearing anti-aging benefits. Glycerin is nongreasy. This means it´s a good choice for anyone with oily skin. Pure ingredients always come with a cost. This is why glycerin soap may be more on the higher end of your personal budget.
