Glycerin - we've all heard of it, but what does it actually do? Glycerin is great for the skin because it acts as a humectant, which is a substance that allows the skin to retain moisture. It can increase skin hydration, relieve dryness, and refresh the skin's surface (which is why we included it in our Skinshot Serum, Supercharged Mix Mask and Micro Exfolistick!) 🧽
