Science & Benefits

Trehalose is a disaccharide (sugar) found in 'resurrection plants' and fungi. It acts as a glass-forming stabilizer: during extreme dryness, it replaces water around the skin's cell membranes to prevent them from collapsing or dehydrating. It is 100% non-comedogenic. It is a 'gold standard' for acne sufferers who experience 'rebound oiliness' due to surface dehydration, as it preserves cellular integrity and maintains a resilient moisture barrier.
