Science & Benefits

Sodium Stearoyl Lactylate is a highly hydrophilic, food-grade emulsifier that significantly enhances the skin's moisture levels by promoting the penetration of other actives. It has a unique ability to bind with the skin's natural proteins to improve barrier function. However, because it is an ester of stearic acid, it is a primary fuel source for the Malassezia yeast associated with fungal acne. While it is non-clogging (rating 1) and safe for standard acne, it should be flagged as a 'Yellow Flag' for individuals with fungal-based skin congestion.
