Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Glycerin (also spelled glycerol) is used in the management of abrasions primarily due to its properties as a humectant and its role in maintaining moisture in the wound environment. Scientific evidence suggests that maintaining a moist wound environment promotes faster re-epithelialization and reduces scab formation, which can ultimately lead to better healing outcomes. Glycerin's ability to attract and retain water helps keep the wound surface hydrated, thereby supporting the healing process. Several studies have explored the use of glycerin-containing dressings and ointments in wound care, including for abrasions. Glycerin is often included in hydrogel dressings, which have been shown to facilitate wound healing by providing moisture and, in some cases, a mildly antimicrobial environment. However, while glycerin's role as a humectant is well-established, direct high-quality clinical trials specifically examining glycerin as a sole agent for abrasions are limited. Most evidence comes from broader studies on moist wound healing and the use of hydrogels or combination ointments. Overall, the use of glycerin in abrasions is scientifically justifiable based on its physical properties and indirect evidence from wound care literature, but the direct clinical evidence specifically for abrasions is not robust. Therefore, the evidence rating is moderate (2/5), reflecting its utility as part of wound care regimens rather than as a primary or sole therapeutic agent.
