Glycerin soap is a type of soap that contains glycerin, a natural humectant that attracts moisture to the skin. This makes it an excellent choice for people with dry or sensitive skin, as it helps to keep the skin hydrated. Glycerin soap is often transparent and can be made with various natural ingredients, including essential oils and botanical extracts. In addition to its moisturizing properties, glycerin soap is gentle and usually free from harsh chemicals, making it suitable for all skin types. It is often used in handmade soaps and can be found in many stores, appealing to those looking for a more natural cleansing option.
