Can Glycerin Dry Out Skin?

Yes, glycerin can dry out the skin in low humidity conditions. “Since glycerin is a humectant, it draws water from its environment,” Dr. Green says. “In low humidity conditions, there is little water in the air, and the nearest source of water is from the deeper layers of the skin. This will cause your skin to become dehydrated and can cause irritation.”
