Science
Mechanism of Action
It functions by sequestering reactive alpha-dicarbonyl compounds, acting as a 'trap' for glycation precursors like methylglyoxal. This prevents harmful cross-linking of dermal proteins such as collagen and elastin, preserving skin structure.

Key findings
- 01 In vitro studies demonstrate 0.1-1% Aminoguanidine HCL inhibits AGE formation by 67-85% by trapping reactive alpha-dicarbonyl intermediates.
- 02 A 2023 study found 0.004% Aminoguanidine HCL achieved 88.11% inhibition of protein glycation in human dermal fibroblasts without causing cytotoxicity.

Formulation
Stability
Stable as a crystalline solid in dark, dry conditions; aqueous solutions are less stable and should be used promptly after preparation.
Conflicts
- Strong oxidizing agents
- Air (prolonged)
- High heat (boiling solutions)
Safety
Safety Profile
Not formally reviewed by CIR for cosmetics, yet widely used in research. GHS classifies the pure form with potential for skin irritation and allergic reactions (H315, H317), though INCIDecoder rates cosmetic irritancy as low.
