Topical cosmetic only. Argireline is typically formulated at 5-10% in leave-on serums, creams, or gels and applied to the target area (e.g., crow's-feet, forehead) twice daily. There is no oral, injectable, or systemic dose — it is not ingested. Concentration and formulation drive how much actually penetrates the skin. This library does not provide an ingestion protocol.

Leave-on topical cosmetic (serum, cream, or gel) at 5-10%
Topical cosmetic only. Matrixyl (palmitoyl pentapeptide-4 / pal-KTTKS, or the Matrixyl 3000 blend of palmitoyl tripeptide-1 + palmitoyl tetrapeptide-7) is used at very low concentrations in leave-on serums and creams — clinical benefit was shown at as little as 3 ppm pal-KTTKS, and consumer products commonly list 3-10% of the branded blend. Applied to the target area once or twice daily. There is no oral, injectable, or systemic dose — it is not ingested.
