Vegetable Glycerin May Moisturize Skin
Vegetable glycerin is a popular skincare treatment because of its moisturizing power. Studies show that adding glycerin to your skin may make your skin smoother and improve its suppleness. Studies also show that applying creams that contain glycerin may improve skin hydration in 10 days. Creams produced from glycerin are more effective than those made from hyaluronic acid [2] or silicone oil at keeping the skin hydrated and preventing loss of moisture.
Studies show that adding glycerin to a warm water bath is more effective at boosting skin moisture levels and protecting against skin irritation than a warm water bath alone.
