Advanced Peptide Complex:
Tripeptide-1 operates through a biomimetic signaling mechanism. As a synthetic fragment corresponding to the N-terminal sequence of type I collagen, it functions as a collagen messenger peptide. By interacting with fibroblast cell surface receptors, tripeptide-1 activates intracellular signaling pathways, specifically upregulating transforming growth factor-beta (TGF-β) transcription. This cascade stimulates the synthesis and deposition of both type I and type III collagen, as well as fibronectin and laminin, thereby enhancing the structural integrity of the extracellular matrix and supporting the appearance of improved skin firmness and elasticity.
Palmitoyl Tetrapeptide-7 exerts its primary effect by modulating the inflammatory response within the skin. This lipopeptide inhibits the production of interleukin-6 (IL-6), a key pro-inflammatory cytokine that activates matrix metalloproteinases (MMPs) responsible for the proteolytic degradation of collagen and elastin. By suppressing IL-6-mediated inflammatory signaling, palmitoyl tetrapeptide-7 helps preserve the structural proteins of the dermal matrix, reducing the catabolic processes that contribute to loss of skin firmness and the appearance of fine lines.
Palmitoyl Pentapeptide-4, a primary component of the Matrixyl complex, functions as a matrikine—a peptide fragment generated during extracellular matrix remodeling. This peptide mimics the natural degradation products of collagen and activates repair mechanisms within fibroblasts. By upregulating gene expression of collagen types I, III, and IV, as well as glycosaminoglycans, palmitoyl pentapeptide-4 stimulates the synthesis of multiple components of the dermal matrix, supporting the restoration of skin thickness, elasticity, and overall structural integrity.
Acetyl Hexapeptide-8 inhibits the formation of expression lines through a targeted neuromodulatory mechanism. This synthetic hexapeptide competitively inhibits the formation of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex, which is essential for the vesicular release of catecholamines and acetylcholine from presynaptic vesicles. By interfering with SNARE complex assembly, acetyl hexapeptide-8 reduces neurotransmitter release at the neuromuscular junction, thereby decreasing the intensity and frequency of facial muscle contractions that contribute to the development and persistence of dynamic wrinkles.
Tripeptide-29 acts as a synthetic collagen precursor peptide that specifically targets collagen type I synthesis. Through direct interaction with collagen-synthesizing machinery in dermal fibroblasts, this tripeptide significantly increases the transcriptional activity and protein expression of procollagen type I. Laboratory investigations demonstrate that tripeptide-29 can achieve substantial increases in collagen type I production, thereby supporting the deposition of new collagen fibers and contributing to improvements in skin volume, plumpness, and wrinkle depth reduction.
Hexapeptide-11 promotes skin matrix remodeling through multiple complementary pathways. This peptide activates the epidermal growth factor receptor and associated signaling cascades, resulting in enhanced transcription of collagen genes and increased fibroblast proliferative capacity. Additionally, hexapeptide-11 upregulates keratinocyte differentiation and corneocyte cohesion, which collectively contribute to improved skin barrier function, increased water retention, and enhanced dermal-epidermal junction integrity.
Glutathione serves as a primary intracellular antioxidant that maintains cellular redox homeostasis. As a tripeptide composed of cysteine, glycine, and glutamic acid, glutathione functions through both direct free radical scavenging and enzymatic recycling via glutathione peroxidase and reductase systems. This dual mechanism protects cellular components—including proteins, lipids, and DNA—from oxidative damage, preserving the functional integrity of skin cells and supporting the efficacy of other active ingredients by maintaining a favorable redox environment conducive to repair and synthetic processes.
Hydration & Conditioning Complex
Super low molecular weight hyaluronic acid facilitates enhanced cutaneous hydration through its capacity for deep stratum corneum and viable epidermal penetration. Unlike high molecular weight hyaluronic acid, which primarily exerts its hydrating effects in the superficial stratum corneum, low molecular weight forms can penetrate to deeper cutaneous layers where they interact with CD44 receptors on keratinocytes. This receptor-mediated interaction promotes sustained water retention within the viable epidermis, enhances cellular water homeostasis, and supports the structural integrity of the extracellular matrix.
The Aquaxyl complex, comprising xylitylglucoside, anhydroxylitol, and xylitol, operates through a multi-dimensional hydrating mechanism that optimizes water reserves and circulation within the stratum corneum. Xylitylglucoside functions as a water-gluco reservoir by forming aquaporin-controlled water zones that facilitate intracellular water transfer. Anhydroxylitol and xylitol complement this activity as polyols that enhance water-binding capacity and support the synthesis of intercellular lipids, thereby maintaining optimal hydration gradients and improving the barrier properties of the stratum corneum.
Green tea extract, primarily through its polyphenolic constituents such as epigallocatechin gallate (EGCG), provides comprehensive antioxidant protection via multiple mechanisms. These catechins exhibit potent free radical scavenging activity, inhibit lipid peroxidation, and suppress the activation of pro-inflammatory transcription factors such as nuclear factor-kappa B. Additionally, EGCG modulates matrix metalloproteinase activity and supports collagen synthesis, providing both protective and reparative benefits that help preserve dermal matrix integrity against environmental stressors.
Caffeine contributes to skin conditioning through its vasoconstrictive and metabolic effects. As a methylxanthine, caffeine inhibits phosphodiesterase, resulting in increased intracellular cyclic adenosine monophosphate levels and subsequent enhancement of lipolysis and microcirculatory function. This mechanism improves cutaneous blood flow and facilitates the removal of metabolic waste products, while its ability to temporarily constrict microvascular permeability helps reduce interstitial fluid accumulation, thereby supporting improved skin firmness and the reduction of localized puffiness.
Dimethyl Isosorbide (DMI), a key functional component of this formulation, serves as an advanced penetration enhancer that significantly increases the transdermal delivery of the active ingredients. DMI is a water-miscible solvent that maintains the peptide complex, hyaluronic acid, and other biologically active components in molecularly dispersed solution throughout the application phase. Unlike traditional volatile solvents that rapidly evaporate and allow active ingredients to precipitate upon contact with the skin, DMI demonstrates low volatility and remains in prolonged contact with the stratum corneum. This sustained solubilization prevents the crystallization of peptides and other active molecules that would otherwise limit their ability to partition from the vehicle into the intercellular lipid domains of the skin barrier.
The penetration-enhancing properties of DMI are mediated through a combination of solvent drag and selective disruption of the stratum corneum lipid structure. As DMI partitions preferentially into the tightly packed, orthorhombic lipid lamellae between corneocytes, it increases the fluidity and disorder of these intercellular lipid domains without causing substantial damage to the barrier’s overall integrity. This transient lipid fluidization expands the effective size of the primary diffusion pathways, enabling the delivery of larger molecules—including peptides and low molecular weight hyaluronic acid—that are typically restricted by the stratum corneum’s size and solubility limitations. The result is substantially enhanced permeation of the active ingredients into the viable epidermis and upper dermis, where they can interact with their cellular targets and exert their biological effects.
The incorporation of DMI into this pre-treatment formulation is particularly significant for achieving optimal synergy with red light therapy. By facilitating the deeper and more efficient delivery of signal peptides, antioxidants, and hydrating agents prior to light exposure, DMI ensures that therapeutic concentrations of these biologically active compounds are present within the target tissues when photobiomodulation occurs. The enhanced penetration achieved through DMI creates a more receptive dermal microenvironment, allowing fibroblasts, keratinocytes, and other responsive cell populations to receive both the exogenous signaling molecules provided by the formulation and the endogenous cellular stimulation generated by red light absorption. This combined approach maximizes the potential for enhanced collagen synthesis, matrix remodeling, and cellular repair processes that characterize the therapeutic benefits of red light therapy.
This enhanced delivery mechanism provided by DMI addresses one of the primary limitations of topical skincare formulations: the inability of many active ingredients to overcome the formidable barrier properties of the stratum corneum. Without effective penetration enhancement, a significant proportion of applied peptides, antioxidants, and other functional ingredients remain sequestered in the superficial layers of the skin, unable to reach the viable cells where they exert their biological effects. By maintaining active ingredients in solution and facilitating their transport through the primary intercellular diffusion pathway, DMI substantially improves the bioavailability and functional efficacy of the formulation’s active components, creating the conditions necessary for these molecules to effectively prepare the skin for subsequent red light therapy and support the cellular processes that are activated by photobiomodulation.
