Discourse around glycerin in sexual lubricants has been clouded by misinformation, with various unqualified sources inaccurately labeling it as a harmful substance. In reality, glycerin is a humectant designed to retain moisture, making it a prevalent ingredient in many lubricants, including flavored or warming varieties.
Concerns regarding glycerin's link to yeast or bacterial infections lack substantial scientific backing, as existing studies, primarily animal-based, do not provide conclusive evidence for humans. Glycerin is one of many potential risk factors for infections, but its presence in lubricants does not guarantee the development of such conditions.
Those at higher risk for candida infections, like individuals with uncontrolled diabetes, may consider avoiding glycerin-based products. However, not all glycerin is the same, with variations in source and purity affecting its quality. Medical-grade, ultra-pure glycerin is preferred for water-based lubricants due to its natural properties and clean application.
While poor-quality ingredients in lubricants can tarnish glycerin's reputation, it is critical to note that lubricant regulations in the US are lacking. Additionally, conflicting study results further complicate the narrative, underscoring the need for more rigorous scientific research.
Ultimately, individuals should educate themselves on lubricant ingredients and choose products that align with their comfort and health, while also enhancing their sexual experiences.
