What Is Erythritol?

Erythritol is a sugar alcohol that functions as a humectant in skincare products. Humectants are a category of ingredients that attract water to the skin, helping to keep the skin's water levels balanced and delivering a dewy, plump, and smooth appearance. Erythritol is often used in combination with other humectants like glycerin and hyaluronic acid to draw and bind moisture to the skin, and then help evenly distribute it within the skin's water channels. This action helps to minimize water loss and keep the skin soft and comfortable.
