Its structure enables interaction with key signaling pathways in fibroblasts and keratinocytes, facilitating enhanced extracellular matrix synthesis, improved skin hydration, and anti-aging effects.In vitro research indicates that Ac-KLKKTETQ-NH2 promotes fibroblast proliferation and upregulates genes responsible for collagen types I and III, elastin, and fibronectin production. By improving ECM density, the peptide contributes to skin firmness, elasticity, and wrinkle reduction.The peptide also modulates inflammatory signaling pathways, reducing pro-inflammatory cytokines such as IL-6 and TNF-α in cultured dermal cells. This anti-inflammatory property supports the maintenance of a healthy dermal microenvironment, promoting cellular repair and resilience against oxidative stress.Due to its small size and amphiphilic properties, Ac-KLKKTETQ-NH2 exhibits efficient penetration into the epidermis in experimental topical formulations, making it suitable for laboratory studies on serums, creams, or emulsions.Synergistic research demonstrates enhanced outcomes when combined with other cosmetic peptides, such as palmitoyl tripeptides or acetyl hexapeptides, as well as antioxidants like vitamin C or niacinamide. Such combinations are shown to improve dermal matrix regeneration, wrinkle reduction, and skin hydration in controlled experiments.Overall, Ac-KLKKTETQ-NH2 serves as a versatile research peptide for investigating anti-aging mechanisms, ECM restoration, fibroblast activation, and skin barrier enhancement in cosmetic science and dermatological research.Product SpecificationsParameterDescriptionProduct NameAc-KLKKTETQ-NH2CAS Number934812-87-0SynonymsAc-KLKKTETQ-NH2Molecular FormulaC54H92N18O13Molecular Weight1185.41 g/molPurity≥99%AppearanceWhite to off-white lyophilized powderSolubilitySoluble in water and DMSOpH StabilityStable between pH 4.5–7.5Storage Temperature2–8 °CCategoryCosmetic peptideApplicationsAnti-aging research, skin elasticity improvement, ECM stimulation, fibroblast activationFormulationSuitable for topical serum, cream, lotion, or emulsion research formulationsStabilityStable under recommended storage and light-protected conditionsShelf Life24 monthsSupplier TypeFactory peptide supplier / OEM cosmetic peptide manufacturerIntended UseFor laboratory research use onlyMechanism of ActionAc-KLKKTETQ-NH2 acts through multiple complementary mechanisms to support skin regeneration and anti-aging research.1. Fibroblast ActivationThe peptide stimulates dermal fibroblasts, increasing proliferation and metabolic activity. Activated fibroblasts synthesize structural proteins essential for dermal integrity.2. ECM Gene UpregulationAc-KLKKTETQ-NH2 upregulates genes encoding collagen I, collagen III, elastin, and fibronectin. This leads to enhanced extracellular matrix density, improved skin elasticity, and wrinkle reduction.3. Collagen and Hyaluronic Acid SynthesisThe peptide promotes collagen and hyaluronic acid production, increasing skin hydration and resilience. ECM reinforcement contributes to smoother, firmer skin.4. Anti-Inflammatory ModulationAc-KLKKTETQ-NH2 reduces pro-inflammatory markers (IL-6, TNF-α), minimizing dermal stress and supporting a regenerative microenvironment.5. Anti-Aging and Wrinkle ReductionBy inhibiting matrix metalloproteinases (MMP-1, MMP-9) and enhancing fibroblast function, the peptide reduces ECM degradation, contributing to visible wrinkle reduction in laboratory studies.6. Synergistic EffectsCo-application with other peptides or antioxidants enhances ECM remodeling, dermal hydration, and anti-aging activity, offering valuable insights in cosmetic formulation research.7. Molecular Pathway RegulationAc-KLKKTETQ-NH2 influences TGF-β/SMAD and MAPK/ERK signaling pathways, promoting collagen transcription, cell proliferation, and anti-inflammatory responses.Side EffectsCytotoxicity: Minimal in vitro; safe within recommended research concentrations.Irritation: No significant irritation observed in reconstructed human epidermal models.Phototoxicity: Not phototoxic under standard laboratory light conditions.Stability Considerations: Sensitive to UV light, high temperature, and extreme pH. Store at 2–8 °C, protected from light and moisture.Experimental Guidance: Concentration-dependent cytotoxicity tests are recommended prior to formulation studies.Ac-KLKKTETQ-NH2 is intended strictly for research purposes and is not suitable for ingestion, injection, or clinical use.KeywordsAc-KLKKTETQ-NH2, anti-aging peptide, skin elasticity peptide, dermal fibroblast activator, ECM stimulator, cosmetic peptide research, factory peptide supplier, peptide wholesale China, cosmetic raw material manufacturer, high-purity cosmetic peptides, OEM & bulk peptide production, China peptide manufacturer, lab-grade peptide, high purity.Shipping GuaranteeAll Ac-KLKKTETQ-NH2 shipments are handled using validated cold-chain logistics to preserve peptide integrity.
