A humectant is a substance that promotes the retention of moisture on the skin. This increased moisture can increase an active ingredient’s solubility, which can then in turn increase the skin penetration. These ingredients deliver light, satiny after-feel to skin formulations and are effective at reducing the tack of glycerin. There are several creams on the market containing these IID-listed humectants and formulated with a variety of APIs. Typical usage level of 1-5%.
