2. Key Cosmetic Benefits

Helps Improve the Appearance of Under-Eye Puffiness

Acetyl Tetrapeptide-5 has been investigated for its activity related to ACE inhibition and vascular permeability. These pathways are relevant to the appearance of fluid-retention-related puffiness around the eyes.

It is suitable for cosmetic formulations targeting a smoother, fresher-looking eye contour.

Supports Dark Circle Care

Acetyl Tetrapeptide-5 is used in targeted eye-care formulations designed to improve the appearance of dark circles and dull-looking skin around the eyes.

Supports Antioxidant Defense

Experimental testing indicates that Acetyl Tetrapeptide-5 can increase SOD (Superoxide Dismutase) activity under tested conditions.

SOD is an important antioxidant enzyme associated with the skin's defense against oxidative stress.

Helps Maintain Skin Firmness

Acetyl Tetrapeptide-5 can be incorporated into eye-care and anti-aging formulations targeting the appearance of fine lines, loss of elasticity and visible signs of skin aging.

3. Experimental Performance Data

CongenPharma's product evaluation includes the following experimental directions:

SOD activity enhancement under different tested concentrations.

ACE activity inhibition under different tested concentrations.

Evaluation of skin brightness and dark-circle appearance after 14 days.

These experimental results provide formulation-development reference information for cosmetic ingredient customers.

Actual cosmetic performance depends on the active concentration, finished formulation, application conditions and overall product design.
