Science & Benefits
Propylene Glycol is a small-molecule humectant and solvent that improves the skin's ability to absorb other active ingredients. It is 100% non-comedogenic. While it is highly effective, it carries a low irritancy rating of 1 for those with extremely sensitive or compromised barriers. In acne formulations, it is the primary vehicle for ensuring that medications (like Salicylic Acid or Clindamycin) reach the deeper parts of the pore where they are most effective.
