Under Eye Treatment With Decapeptide-12
01
Product Description
1. Mechanism of Action (MOA)
Decapeptide-12 is a multifunctional synthetic peptide specifically engineered to target the primary causes of under-eye dark circles and puffiness. Its mechanism is multi-pronged:
Inhibition of Advanced Glycation End Products (AGEs):
Glycation is a process where sugars bind to proteins like collagen, forming AGEs. This leads to stiff, discolored (yellowish-brown) tissue, a key contributor to under-eye darkness.
Decapeptide-12 acts as a glycation inhibitor, protecting collagen and other proteins from this damage, thereby helping to prevent the yellowish pigmentation associated with AGEs.
Improvement of Microcirculation:
Dark circles with a bluish or purple tint are often caused by poor microcirculation and the pooling of deoxygenated blood in the delicate under-eye capillaries.
Decapeptide-12 helps to strengthen capillary walls and reduce vascular permeability, minimizing blood leakage and stasis. This action reduces the appearance of bluish vascular dark circles.
Reduction of Fluid Accumulation (Puffiness):
By supporting healthy lymphatic drainage and reducing capillary leakage, it helps to diminish under-eye puffiness and bags.
2. In Vitro Efficacy Data
Anti-Glycation Activity:
In a cell-free assay, Decapeptide-12 demonstrated a dose-dependent inhibition of AGEs formation, showing over 40% inhibition at a concentration of 100 µM.
Endothelial Cell Barrier Protection:
In a model of vascular inflammation using Human Umbilical Vein Endothelial Cells (HUVEC), Decapeptide-12 significantly reduced endothelial hyperpermeability, indicating its ability to strengthen blood vessels and prevent leakage.
3. Clinical Results
*A 56-day, monocentric clinical study was performed on female volunteers with noticeable under-eye dark circles and puffiness.*
Instrumental Analysis:
Colorimetry: Measurement of under-eye skin color showed a significant reduction in the a value (redness) and b value (yellowness)** on the L*a*b* scale, indicating a visible lightening of dark circles.
Puffiness Reduction: A -18% reduction in under-eye puffiness was measured using 3D image analysis after 56 days of application (twice daily with a 2% formulation).
Expert Grader Assessment:
Dermatological evaluation confirmed a visible improvement in the severity of dark circles in over 80% of the subjects after 28 days.
Self-Assessment Questionnaires:
90% of participants reported that their under-eye area looked "brighter and more refreshed."
85% agreed that puffiness was significantly reduced, making their eyes appear less tired.
