Acetyl Tetrapeptide-3 Injection

structural restoration, pathway unclogging and functional activation, far exceeding the short-term temporary de-puffing effect of conventional moisturizing ingredients: It specifically acts on periorbital lymphatic endothelial cells to stimulate their proliferation and repair activity, restores damaged lymphatic vessel wall architecture, enhances wall integrity and elasticity, and corrects permeability disorders caused by inflammation and external irritants to mitigate abnormal lymphatic leakage.

It also modulates the contraction rhythm of lymphatic smooth muscle, boosts the pumping efficiency of superficial lymphatic vessels, accelerates drainage of stagnant interstitial fluid and metabolic waste around the eyes, and rapidly alleviates acute edema.
It modulates signaling pathways governing lymphatic microcirculation to promote moderate expression of Granulocyte Chemotactic Protein-2 (GCP-2).

It precisely recruits immune scavenger cells to damaged periorbital areas to clear accumulated metabolic debris and mild inflammatory deposits within lymphatic lumens, unclog micro-occlusions and fully relieve lymphatic stasis.

2. Block Inflammation-Mediated Edema Cascade Reactions
Acetyl tetrapeptide-3 injection Inflammatory responses are the primary driver of persistent periorbital edema and a critical aggravator of microcirculatory dysfunction, which this peptide effectively intervenes in:

It markedly suppresses IL-6 secretion in cutaneous keratinocytes and downregulates UVB and external irritant-triggered inflammatory skin responses, reducing sustained damage to periorbital microvessels and lymphatic ducts from inflammatory factors.
By blocking inflammatory signal transduction, it lowers abnormal microvascular permeability, curbs excessive interstitial fluid generation and eliminates the root substrate for edema formation.

but they should be interpreted as ingredient-specific supplier data unless the underlying methods and full datasets are publicly available. The most appropriate cosmetic claim is consequently supportive rather than therapeutic:

the ingredient may help optimize the appearance of skin texture, suppleness, and surface regularity when used in a well-designed formulation. It should not be described as treating wounds, reversing fibrosis, or regenerating damaged tissue in the medical sense. It also suppresses infiltration and aggregation of dermal inflammatory cells to mitigate inflammatory swelling of periorbital tissues and relieve inflammatory compression on lymphatic vessels, creating unobstructed tissue conditions for lymphatic drainage.
Acetyl tetrapeptide-3 injection It repairs the dermoepidermal junction and strengthens the skin barrier to reduce repeated periorbital tissue damage from external irritants and lower edema recurrence risk, achieving synergistic anti-inflammatory and de-puffing benefits.

Abundant matrix proteins densify the periorbital dermis, tighten loose subcutaneous connective tissue, boost skin support and firmness, and narrow interstitial gaps to physically limit abnormal fluid accumulation and recurrent swelling. Ordered matrix protein synthesis precisely modulates colloid osmotic pressure in periorbital tissues, balancing fluid exchange dynamics among blood vessels, interstitial spaces and lymphatic ducts to prevent abnormal fluid pooling from isolated osmotic imbalances and sustain microcirculatory homeostasis.
