- Ferulic Acid
- Antioxidant, often combined with vitamin C and E; 0.5-2%, photolabile
- Phloretin
- Not decoded yet
- Hydrolyzed Collagen
- Hydrolyzed protein for film-forming and moisture; molecular weight limits penetration, check source for shellfish allergies
- Hyaluronic Acid
- High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.
