Decapeptide-4: KGF-Mimetic Peptide for Intensive Epidermal Repair Decapeptide-4 is a biomimetic decapeptide engineered to reproduce the signaling activity of keratinocyte growth factor (KGF/FGF-7). With a molecular weight of approximately 1100 g/mol, this custom-synthesis peptide targets the FGFR2-IIIb receptor on basal keratinocytes, triggering proliferation and accelerated epidermal turnover. TCS NEXUS S.L. supplies research-grade and cosmetic-grade Decapeptide-4 […]

Copper peptides have been used in skincare for over 30 years, yet most formulators still think of GHK-Cu (CAS 89030-95-5) as just a “repair peptide.” That sells it short. GHK-Cu simultaneously drives collagen synthesis, suppresses inflammatory cytokines, and reduces oxidative damage — and all three mechanisms have solid in-vitro data behind them. If you are

Carnosine HCl: Anti-Glycation Dipeptide for Advanced Skin Care Formulations If you formulate anti-aging products and have not yet explored carnosine, you are leaving measurable efficacy on the table. Carnosine (beta-alanyl-L-histidine) is a naturally occurring dipeptide with a direct, well-documented mechanism against glycation-driven skin aging. We supply the hydrochloride salt form at TCS NEXUS S.L. because

Biotinoyl Tripeptide-1 is a biotin-peptide conjugate engineered to strengthen hair follicle anchoring and promote lash and brow growth. With a molecular weight of approximately 600 g/mol and CAS number 299157-54-3, this ingredient pairs the follicle-targeting properties of biotin with a tripeptide sequence that stimulates keratinocyte matrix proteins. TCS NEXUS S.L. supplies Biotinoyl Tripeptide-1 from our

Avobenzone (Butyl Methoxydibenzoylmethane) – Broad-Spectrum UVA Filter Avobenzone is the most widely used organic UVA filter in global sun care. With absorption spanning 310-400 nm and a peak at 357 nm, it delivers broad UVA coverage that no other oil-soluble organic filter matches at equivalent use levels. TCS NEXUS S.L. supplies pharmaceutical-grade Avobenzone from EU

Acetyl Tetrapeptide-9 is a lumican-stimulating peptide engineered to improve collagen fibril organization in the dermis. With a molecular weight of approximately 530 g/mol and CAS number 928006-50-2, this tetrapeptide targets a specific proteoglycan pathway that most collagen-boosting actives miss entirely. TCS NEXUS S.L. supplies Acetyl Tetrapeptide-9 from our warehouse in Valencia, Spain at purity levels

Acetyl Dipeptide-1 Cetyl Ester for Sensitive Skin and Comfort Formulations When formulating for reactive, post-procedure, or discomfort-prone skin, ingredient selection matters more than layering actives. Acetyl Dipeptide-1 Cetyl Ester, known commercially as Calmosensine, is a lipophilic dipeptide designed to mimic endorphin receptor activation at the skin level. The cetyl ester modification gives this peptide oil-phase

Acetyl Decapeptide-3 is a biomimetic growth factor peptide designed to replicate endogenous signaling cascades that drive dermal repair. With a molecular weight of approximately 1200 g/mol and CAS number 935288-50-9, this decapeptide triggers fibroblast activation without relying on recombinant growth factors. TCS NEXUS S.L. supplies Acetyl Decapeptide-3 from our warehouse in Valencia, Spain at purity
