Acetyl Hexapeptide-38: Volumizing Peptide for Lip and Facial Contouring Acetyl Hexapeptide-38 (CAS 1400634-44-7) is a bioactive hexapeptide engineered for non-invasive lip volumization and facial soft-tissue contouring. This peptide targets adipogenesis pathways, making it one of the few cosmetic actives capable of stimulating localized volume enhancement without dermal fillers. TCS NEXUS S.L. supplies Acetyl Hexapeptide-38 from […]

Dipeptide-2: Anti-Puffiness Eye Contour Peptide for Professional Formulations If you develop eye contour products, Dipeptide-2 is one of the few peptides with a specific, measurable mechanism for reducing periorbital puffiness. This Val-Trp dipeptide (CAS 24587-37-9, MW 202.21 g/mol) promotes lymphatic drainage in the under-eye area and strengthens capillary walls, addressing the two primary causes of

Myristoyl Tetrapeptide-12: Conditioning Lipopeptide for Hair and Skin Keratin Quality Myristoyl Tetrapeptide-12 (CAS 959610-24-3) is a conditioning lipopeptide designed to improve keratin protein quality in both skin and hair applications. The tetrapeptide sequence is conjugated to myristic acid (C14 chain), providing lipophilic character for effective integration with the keratin-rich structures of the stratum corneum and

Myristoyl Hexapeptide-16: Scalp-Care Peptide for Hair Follicle Anchoring Myristoyl Hexapeptide-16 (CAS 959610-54-9) is a lipopeptide designed for scalp and hair care applications, specifically targeting the structural proteins responsible for hair follicle anchoring within the dermal papilla. By strengthening the attachment between the hair fiber root sheath and surrounding connective tissue, this peptide reduces hair breakage

Myristoyl Pentapeptide-17: Eyelash and Eyebrow Enhancing Peptide Myristoyl Pentapeptide-17 (CAS 959610-30-1) is a lipopeptide specifically developed for eyelash and eyebrow enhancement through keratin gene expression stimulation. The myristoyl fatty acid chain provides targeted delivery to hair follicle keratinocytes, while the pentapeptide sequence activates keratin biosynthesis pathways critical for lash fiber growth and thickness. TCS NEXUS

Myristoyl Pentapeptide-4: C14 Lipopeptide for Collagen I and III Stimulation Myristoyl Pentapeptide-4 is a lipopeptide consisting of a five-amino-acid sequence conjugated to myristic acid (C14 fatty acid chain). This structural design follows the same lipopeptide engineering principle used in palmitoyl-conjugated peptides but employs the shorter C14 chain, which alters the compound partition coefficient and stratum

Acetyl Tetrapeptide-3: Hair Follicle Support Peptide for Density and Anti-Hair Loss Acetyl Tetrapeptide-3 (INCI: Acetyl Tetrapeptide-3, CAS 827306-88-7) is a four-amino-acid acetylated peptide with a molecular weight of 487.55 g/mol. Its sequence – Ac-Lys-Gly-His-Lys-NH2 – was developed to support hair follicle anchoring and reduce the factors that contribute to follicular miniaturization. This peptide forms the

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

Palmitoyl Tetrapeptide-10: Smoothing Lipopeptide for Type IV Collagen at the DEJ Palmitoyl Tetrapeptide-10 (CAS 887140-79-6, MW ~620 g/mol) is a smoothing lipopeptide that stimulates type IV collagen production specifically at the dermal-epidermal junction (DEJ). The DEJ is the specialized basement membrane zone where the epidermis anchors to the dermis through a network of type IV

L-Anserine: Methylated Anti-Glycation Dipeptide for Advanced Skin Protection L-Anserine (CAS 584-85-0, MW 240.26 g/mol) is beta-alanyl-1-methylhistidine, a naturally occurring dipeptide found at high concentrations in avian and fish skeletal muscle. Structurally, it is a methylated analog of carnosine — the methyl group on the N1 position of the imidazole ring confers superior anti-glycation activity and
