Clinical Evidence

Acne Management

A systematic review highlights the role of propanediol in acne treatment, particularly when combined with other sweeteners like xylitol. These combinations may help regulate acne pathogenesis and exhibit antibacterial properties against Cutibacterium acnes Effects of nutritive and non-nutritive sweeteners on acne vulgaris: A systematic review.

Psoriasis Treatment

In an observational study, a formulation containing propanediol demonstrated significant improvements in patients with palmoplantar psoriasis. The study reported a 40% reduction in lesion extent and a 50% improvement in inflammation after 8 days of treatment Efficacy of a topical polyphenol-based formulation in palmoplantar psoriasis: an observational study.

Microbiome Interactions

Research indicates that propanediol may play a role in the gut-oral-skin-heart microbiota axis, potentially influencing systemic inflammation and oxidative stress, which are critical in various dermatological and cardiovascular conditions The Gut-Oral-Skin-Heart Microbiota Axis and Oxidative Stress: Where Have We Been and Where Are We Going.

Conclusion

Propanediol is a valuable ingredient in skincare, offering hydration and potential therapeutic benefits in managing acne and psoriasis, while also interacting with the microbiome to support skin health.
