Product Description & Mechanism of Action

Dipeptide-2 Mechanism

Dipeptide-2 is a bioactive dipeptide that functions through a sophisticated, neuro-physiological pathway targeted at improving skin health and appearance.

Enkephalinase Inhibition: Its primary mechanism is the inhibition of the enzyme enkephalinase, which is responsible for the degradation of endogenous enkephalins.

Enkephalin Potentiation: By inhibiting this enzyme, Dipeptide-2 increases the local concentration and prolongs the activity of neuropeptides with opioid-like activity.

The Pathway to Results:

  • Stimulation of Lymphatic Contractility: Enkephalins bind to delta-opioid receptors on lymphatic endothelial cells, triggering a calcium-dependent signaling cascade.
  • Enhanced Drainage: Increased contractility accelerates the removal of stagnant lymph fluid, metabolic waste, and accumulated proteins.
  • Visible Improvement: This process reduces edema and improves microcirculation, specifically in the periorbital area.
Summary: Dipeptide-2 ➔ Inhibits Enkephalinase ➔ Increases Enkephalins ➔ Stimulates Lymphatic Contraction ➔ Boosts Drainage ➔ Reduces Puffiness & Dark Circles.

Frequently Asked Questions

What is the primary function of Dipeptide-2 in skincare?
Dipeptide-2 is primarily used to reduce under-eye puffiness and dark circles by stimulating lymphatic drainage through enkephalinase inhibition.
How effective is Dipeptide-2 according to clinical studies?
Clinical evaluations have shown up to a 70% reduction in under-eye puffiness volume when using a formula containing 0.05% Dipeptide-2 over 28 days.
Is this ingredient safe for the sensitive eye area?
Yes, it is non-irritating, non-cytotoxic, and specifically designed to be well-tolerated by the delicate skin around the eye contour.
What is the recommended usage level in formulations?
The recommended concentration is between 0.05% and 0.5% in the final cosmetic product.
Are there any specific formulation requirements?
It is water-soluble, stable within a pH of 4.0 - 8.0, and should be added to formulations at temperatures below 45°C to protect its bioactivity.
Is Dipeptide-2 suitable for vegan products?
Yes, it does not contain animal-derived components and is not tested on animals.
