A cosmetic peptide that stimulates lumican production to strengthen skin structure and reduce fine lines.
Acetyl Tetrapeptide-9 (marketed as Dermican by Lipotec) is a synthetic tetrapeptide designed to increase production of lumican — a small leucine-rich proteoglycan in the dermis that organizes collagen fibers into optimal structural arrangements. Without proper lumican levels, collagen fibers are disorganized, leading to reduced skin firmness and increased fine lines.
As skin ages, lumican production decreases, causing collagen fiber disorganization even when collagen quantity is maintained. Acetyl Tetrapeptide-9 addresses this by signaling dermal fibroblasts to produce more lumican, effectively improving the structural organization of existing and new collagen.
This mechanism is complementary to collagen-stimulating peptides like Matrixyl — while Matrixyl increases collagen quantity, Acetyl Tetrapeptide-9 improves collagen quality and organization.
In vitro studies demonstrate Acetyl Tetrapeptide-9 increases lumican production in human dermal fibroblasts. Collagen fiber organization was improved in treated skin models. Clinical studies showed reduced fine line depth and improved skin firmness.
The lumican pathway represents a unique mechanism distinct from other cosmetic peptides. Combining Acetyl Tetrapeptide-9 with collagen-stimulating peptides may provide synergistic anti-aging effects.
