1.MECHANISM OF ACTION

Acetyl Tetrapeptide-2 works through a dual-action circulatory and drainage mechanism:

Microcirculation Enhancement: It helps to stimulate and improve blood microcirculation in the capillaries beneath the eyes. This action can help disperse pooled blood and reduce the bluish or purplish hue associated with vascular dark circles.
Lymphatic Drainage Promotion: The peptide aids in activating the lymphatic system around the eyes. This promotes the removal of excess fluid, metabolic waste, and proteins that accumulate in the interstitial tissue, thereby reducing puffiness and under-eye bags.

By addressing both color (through circulation) and volume (through drainage), it targets the primary causes of a tired-looking eye area.

2.PRODUCT INDICATIONS

This product is indicated for cosmetic science and the formulation of targeted eye care and brightening products. Key applications include:

As a primary active ingredient in serums, gels, creams, and patches specifically formulated for the under-eye area.
In products designed to reduce the appearance of dark circles, puffiness, and under-eye bags.
For formulations aimed at providing a brightened, refreshed, and well-rested look to the eye contour.
As part of comprehensive treatments for periorbital hyperpigmentation and fluid retention.

3.CLINICAL EFFICACY OF PRODUCT

Acetyl Tetrapeptide-2 is supported by clinical cosmetic studies. Evaluations of formulations containing this peptide typically demonstrate:

A visible reduction in the intensity and surface area of under-eye dark circles.
A measurable decrease in under-eye puffiness and swelling.
An overall brightening and smoothing effect on the eye contour area.
Subjective improvements in the appearance of fatigue and a more alert look.

These results validate its efficacy as a specialized bioactive for improving the aesthetic concerns of the periocular region.
