Peptide

Dipeptide-2

targeted peptide that helps reduce the appearance of under-eye puffiness, support skin firmness, and promote a smoother, fresher, more revitalized-looking eye area.

Key Benefits

  • Helps reduce the look of puffiness
  • Supports a refreshed eye contour
  • Complements firming peptide blends
  • Helps smooth dehydration lines
  • Targets visible signs of fatigue

How It Works

Dipeptide-2 is commonly described as a valine-tryptophan peptide with angiotensin-converting-enzyme inhibitory activity in laboratory testing. The proposed cosmetic rationale is support for fluid balance around the eye contour.

A 28-day clinical study of a multi-peptide eye serum that included Dipeptide-2 reported improvements in wrinkles, hydration, elasticity, firmness, and fatigue-related appearance. The study design evaluates the complete serum and does not establish Dipeptide-2 as the sole cause.

Real-world results depend on formula composition and the underlying reason for puffiness. Structural eye bags, allergies, and medical edema are outside the scope of a cosmetic peptide.

What It Is

A synthetic valine-tryptophan dipeptide used in cosmetic eye care. It is a topical appearance-support ingredient rather than a drug for edema or a replacement for medical evaluation.

What It Does

Helps the eye contour look less puffy, smoother, and more refreshed when used in a targeted multi-ingredient formula. Claims should remain conservative because isolated clinical evidence is limited.

Dipeptide-2 FAQs

Common questions about this ingredient in skincare.

What is Dipeptide-2?
It is a two-amino-acid cosmetic peptide, commonly identified as valine-tryptophan, used mainly in formulas for puffy-looking eyes.
How does it help under-eye puffiness?
It is proposed to influence ACE-related pathways associated with local fluid balance, but direct clinical proof for the peptide alone remains limited.
Does it remove permanent eye bags?
No. Topicals cannot reliably remove structural fat pads or genetically determined eye bags. They may improve temporary puffiness and overall appearance.
Can it reduce wrinkles?
It may support a smoother look within a multi-ingredient eye formula, especially when dehydration is involved, but it is not a stand-alone wrinkle treatment.
Can it be combined with other peptides or caffeine?
Yes. Dipeptide-2 is commonly used in blends with other peptides, humectants, and caffeine to address multiple causes of a tired-looking eye area.
What does the clinical evidence show?
A human study reported benefits from a multi-peptide serum containing Dipeptide-2, but the design cannot separate its individual contribution from the other peptides and formula base.
