Science
Mechanism of Action
This peptide operates at the cellular level as a sophisticated signaling molecule, initiating regenerative processes that support overall skin well-being. It mimics β-endorphin, a natural soothing agent, to alleviate discomfort and simultaneously inhibits the release of CGRP (Calcitonin Gene-Related Peptide), thereby reducing inflammation and burning sensations. By stimulating skin nerve cells to release met-enkephalin, an opioid messenger, it delivers relaxing and pain-relieving effects, rapidly decreasing irritations caused by heat, chemicals, or mechanical stress. Furthermore, it inhibits the release of Substance P from nerve endings, moderating exaggerated skin responses such as redness, stinging, and swelling. It also reduces the expression of pro-inflammatory cytokines (IL-1, IL-6, TNF-α), contributing to its anti-inflammatory properties and strengthening the skin barrier by increasing proteins like AQP3, FLG, caspase-14, and cytokeratin 10. Activating fibroblasts, it boosts the synthesis of elastin and tropoelastin, crucial for enhancing skin tone, elasticity, and firmness. Additionally, studies suggest antioxidant, antiglycation, and autophagy-activating effects, all contributing to its comprehensive anti-senescence profile.

Key findings
- 01 Demonstrated efficacy in reducing redness, itching, and general skin irritation, particularly when induced by capsaicin.
- 02 When incorporated into a cream and applied twice daily for two months, 80% of panelists observed reduced visible effects of gravity, decreased cutaneous sagging, and significantly firmer skin.
- 03 Promotes the synthesis of elastin and tropoelastin, with studies showing up to a 90% increase in elastin fiber synthesis compared to control samples.
- 04 Commonly applied in finished products, with lower concentrations often used for sensitive skin and the eye region, while higher concentrations are favored in anti-aging formulations for enhanced tone and elasticity.

Stability
Optimal effectiveness is observed within a pH range of 5.0 to 7.0; extreme acidic or alkaline conditions may impair its efficacy. For optimal stability, it should be incorporated into formulations during the final processing phase once temperatures have dropped below 40 °C. The ingredient exhibits high stability and is suitable for integration into various formats, including emulsions, gels, and serums.

Safety
Safety Profile
Acetyl Dipeptide-1 Cetyl Ester is considered safe for cosmetic use, demonstrating general tolerability even for sensitive or irritation-prone skin. Significant adverse reactions are infrequent, with mild irritation being a rare possibility for highly sensitive individuals. While extensively evaluated for cosmetic safety by general regulatory authorities, specific assessments by bodies like CIR, SCCS, or FDA were not identified in the available research.
