Check the back of your favorite lotion and you’ll likely find glycerin hiding on the ingredient label. That’s often a good thing. When naturally derived from vegetables, glycerin is a hero skincare ingredient that will seriously hydrate your skin. Studies show that glycerin effectively treats chronic dry skin, and it’s good for anyone hoping to add suppleness.
Where Does Glycerin Come From?
Glycerin is a colorless and odorless liquid that can be used on its own or as an added ingredient. Not all glycerin is the same. It can be derived naturally from animal or plant lipids, or synthetically from petroleum. The non-vegetable varieties of glycerin (animal or petroleum derived) can have significant amounts of residual methanol, which is potentially toxic. So it’s best to go for vegetable glycerin, which can also replace other potentially-dangerous ingredients like dimethicone, cyclomethicone, or mineral oil.
What Makes Glycerin Good For Your Skin
Different moisturizers work differently. Occlusive moisturizers create a barrier to keep moisture in, while emollients smooth your skin by filling the dry and cracked areas. Glycerin is in yet another category: it’s a humectant, meaning it actually attracts water. (Honey and hyaluronic acid are other examples of humectants.) “Glycerin is a highly effective skincare ingredient,” Karen Behnke, founder and CEO of Juice Beauty, told me. With glycerin, you’re not just preserving the moisture that exists on your skin, but getting more. “In conjugation with other oils and emollients on the skin, it can provide long lasting hydration,” Behnke said. In their line, Juice Beauty only uses plant lipid glycerin sustainably sourced generally from coconuts.
The Best Ways to Use Glycerin
Because of its powerful properties, many cosmetics contain glycerin. You also can buy pure vegetable glycerin on Amazon and incorporate it into your existing routine. Apply it on its own directly after a shower while your skin is still wet, or to your wet hair as a leave-in conditioner. You can also add the raw stuff to your shampoo, bath products, or moisturizers to get extra hydration, since glycerin naturally draws in moisture. I like to add it to my sweet almond oil and apply it all over before bed.

Behnke told me that Juice Beauty uses glycerin in their serums and moisturizers. Below are some high-performing skin care products from them and others that contain glycerin and also get a safe rating from the Environmental Working Group (EWG).
