Multi-Peptide + HA Serum

DESCRIPTION

What It Does: Inhibits neuromuscular acetylcholine release for reduced facial muscle contraction and expression line formation.

Why It's Used: Enhanced argireline analog with improved stability for formulations requiring optimized neuro-inhibiting anti-wrinkle performance.

How It Works: Competes with snap-25 protein for binding to the snare complex, reducing vesicular acetylcholine release at neuromuscular junctions. reduced acetylcholine binding decreases muscle contraction amplitude, reducing expression line depth with repeated use.

Typically Found In: Anti-wrinkle creams,expression line treatments,forehead/eye area products

DESCRIPTION

What It Does: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.

Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.

How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.

Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners

DESCRIPTION

What It Does: Provides simultaneous stimulation of 6 major skin matrix proteins for comprehensive anti-aging matrix restoration.

Why It's Used: The most comprehensive matrix-stimulating peptide — matrixyl synthe'6's simultaneous upregulation of all six major skin matrix proteins provides more complete extracellular matrix restoration than any single-target peptide.

How It Works: Activates multiple fibroblast receptor pathways simultaneously. upregulates collagen i, iii, iv synthesis. stimulates fibronectin, laminin-5, and ha synthase (has2) expression. comprehensive matrix restoration reduces wrinkle depth from all collagen and ha-dependent skin architecture components.

Typically Found In: Premium anti-aging serums,comprehensive anti-aging products

SCIENTIFIC NOTE

Matrixyl synthe'6's six-protein stimulation was characterised by sederma's research demonstrating simultaneous mrna upregulation for all six matrix proteins in human skin explants. the breadth of matrix stimulation from a single tripeptide reflects the convergent gene regulation of extracellular matrix proteins — many share common transcription factor binding sites (ap-1, sp1) allowing coordinated upregulation from a single signalling peptide.

DESCRIPTION

What It Does: Provides hyaluronic acid hydration in the most formulation-stable and compatible form.

Why It's Used: The standard form of ha used in cosmetics – more stable than free ha, better solubility, and equivalent skin hydration benefits.

How It Works: Sodium salt reduces the polyelectrolyte repulsion of ha chains, allowing better packing in formulations. on skin, sodium ions dissociate and the ha chain unfolds to its full water-binding conformation. provides full ha humectant and barrier benefits equivalent to free ha.

Typically Found In: Hydrating serums,toners,moisturizers,sheet masks,anti-aging products
