1.MECHANISM OF ACTION
- Stimulation of Fibroblast Activity: The peptide is recognized by specific receptors on the surface of fibroblasts, triggering intracellular signaling cascades.
- Enhanced Synthesis of ECM Components: This signaling leads to the upregulated production of collagen types I, III, and IV, elastin, and fibronectin. These proteins are fundamental for skin strength, elasticity, and resilience.
- Reinforcement of the Dermal-Epidermal Junction (DEJ): By promoting the synthesis of collagen IV (a primary component of the DEJ) and other anchoring proteins, it helps strengthen the critical connection between the dermis and epidermis. This can improve skin firmness and counteract sagging.
- Improvement of Skin Micro-architecture: The overall increase in dermal matrix density contributes to thicker, more toned-looking skin.
2.PRODUCT INDICATIONS
- As a primary active in firming serums, lifting creams, and neck treatments targeting loss of skin elasticity and sagging.
- In products designed to improve skin density, tonicity, and overall facial contour.
- For formulations aimed at strengthening the dermal-epidermal junction and improving skin's structural integrity.
- As a key component in comprehensive anti-aging regimens that address both wrinkles and loss of firmness.
- In products for preventative aging care to help maintain skin's youthful support structure.
3.CLINICAL EFFICACY OF PRODUCT
- Significant Improvement in Skin Firmness and Elasticity: Objective measurements (e.g., cutometry) show enhanced skin viscoelastic properties.
- Visible Reduction in Signs of Sagging: Subjective assessments and photographic analysis indicate a more lifted and toned appearance, particularly in areas like the jawline and cheeks.
- Improved Skin Density and Smoothness: The skin appears plumper and more refined due to the enhanced dermal matrix.
- Results that Contribute to a More Youthful Facial Contour: Regular use helps counteract the effects of gravity and volume loss associated with aging.
