Outcomes where both Argireline and Vitamin C (topical) have evidence — compare verdict strength side-by-side.
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.
any
Leave-on topical cosmetic (serum, cream, or gel) at 5-10%
Topical cosmetic only. L-ascorbic acid serums are typically 10-20% (often near pH 3 for absorption); stable derivatives are used at varying percentages. Apply a few drops to clean, dry skin, usually in the morning under sunscreen (its antioxidant action complements SPF). There is no oral, injectable, or systemic dose in this cosmetic context. This library does not provide an ingestion protocol.
