Oligopeptide-2 Lift & Tighten Sagging Skin
01
Product Description
I. Mechanism of Action (MOA)
Oligopeptide-2 is a biomimetic signal peptide specifically designed to combat signs of skin aging by targeting the fundamental structure of the dermis. Its mechanism is focused on extracellular matrix (ECM) rejuvenation.
Collagen & Elastin Synthesis: It functions as a key messenger, signaling dermal fibroblasts to upregulate the production of essential structural proteins, primarily collagen Type I, III, and elastin. This directly counteracts the age-related decline of these components.
Dermal-Epidermal Junction (DEJ) Reinforcement: The peptide helps strengthen the DEJ, the critical interface between the dermis and epidermis. A robust DEJ improves skin firmness, resilience, and nutrient exchange.
Anti-Wrinkle & Firming Action: By boosting the synthesis of core structural proteins and reinforcing the DEJ, Oligopeptide-2 effectively smooths the appearance of existing wrinkles and prevents the formation of new ones, resulting in visibly firmer, tighter skin.
II. In Vitro Efficacy Data
Fibroblast Activation Assays: In vitro studies on human dermal fibroblasts demonstrate that Oligopeptide-2 significantly enhances fibroblast proliferation and metabolic activity in a dose-dependent manner.
ECM Protein Quantification: Immunoassay and PCR analysis confirm a marked increase in the secretion of procollagen Type I and tropoelastin in cell cultures treated with Oligopeptide-2, validating its core mechanism.
DEJ Component Expression: Research indicates that Oligopeptide-2 can upregulate the expression of key DEJ proteins, such as collagen IV and VII, contributing to improved dermal-epidermal cohesion.
III. Clinical Results
Clinical trials on formulations containing Oligopeptide-2 have demonstrated significant improvements in key signs of skin aging.
Wrinkle Reduction: A double-blind, vehicle-controlled study with a serum containing Oligopeptide-2 showed a statistically significant reduction in the depth and volume of fine lines and wrinkles (particularly in the crow's feet and forehead areas) after 12 weeks of use. Assessment was performed via skin replicas and optical profilometry.
Improvement in Skin Firmness & Elasticity: Instrumental measurements (e.g., Cutometer) confirmed a significant increase in skin firmness, elasticity, and overall tightness in the treatment group compared to the control.
Global Clinical Grading: Dermatologist assessments noted a visible improvement in overall skin smoothness, tightness, and youthful appearance.
Safety Profile
Oligopeptide-2 is engineered for topical safety. It is non-irritating, non-sensitizing, and well-tolerated by all skin types, as confirmed by Human Repeat Insult Patch Testing (HRIPT).
Biocompatibility
As a peptide, it is inherently biocompatible with skin biology.
Formulation Compatibility
It is a water-soluble ingredient with excellent stability in a wide pH range. It is highly compatible with most cosmetic formulations, including serums, creams, and lotions, and works synergistically with other anti-aging actives like antioxidants, hyaluronic acid, and other peptides.
