What is Erythritol?

Erythritol is a naturally occurring four-carbon sugar alcohol found in fruits like melons and pears, as well as in fermented foods such as wine and soy sauce. It is also commercially produced via yeast fermentation of glucose from corn or wheat. In skincare products, it functions mainly as a humectant within moisturizers, serums, toners, and cleansers. Its hydrophilic nature enables it to draw atmospheric moisture and bind water within the skin's outer layers, promoting hydration without a heavy residue. This mechanism enhances skin suppleness and resilience by aiding the stratum corneum's water retention. Erythritol's low molecular weight facilitates better absorption compared to larger polyols, and its neutral taste and texture make it suitable for diverse formulations, including sensitive skin care and oral-hygiene hybrids.
