Transdermal Peptide

Transdermal peptides, also commonly referred to as skin-penetrating peptides, are a class of functional peptides synthesized with artificially designed sequences. A typical representative sequence is ACSSSPSKHCG, consisting of 11 amino acid residues. These peptides rely on disulfide bonds formed by internal cysteine residues to construct a stable amphiphilic three-dimensional conformation. Unlike active peptides that directly provide anti-wrinkle, skin-brightening, and repairing benefits, it do not primarily function to directly improve wrinkles or lighten pigmentation; Instead, its core function is as a bio-permeation carrier ingredient.

temporarily disrupting the ordered arrangement of stratum corneum lipids to create reversible molecular transport channels. This helps active ingredients in the formulation cross the stratum corneum. This process does not damage the cellular structure of the stratum corneum; once the ingredient is removed, the skin barrier's lipid structure can spontaneously return to its original state; Second, certain transdermal peptides can bind to charged sites on the cell membrane surface and, through endocytosis, transport active cargo into living epidermal cells, enabling delivery at the cellular level and reducing the problem of large-molecule active ingredients remaining on the skin's surface without being absorbed.

these data are based on in vitro models and do not guarantee that skin will achieve the same level of enhancement.As a manufacturer specializing in the R&D and production of peptide ingredients, Bloomtechz has achieved large-scale synthesis and multi-stage purification of it and is able to provide the raw materials in various purity grades, accompanied by comprehensive batch quality reports. Leveraging an excellent sales team and a one-on-one service model, we provide skincare manufacturers and formulation R&D institutions with a full range of support-including raw material selection, formulation pre-evaluation, and compliance documentation-to help clients avoid pitfalls when incorporating penetration-enhancing ingredients into their formulations.

and cupric blue peptide-have relatively high molecular weights. Due to the 500-dalton threshold for passive skin permeation, a significant amount of the active ingredient remains on the surface of the stratum corneum when applied topically alone, making it difficult for it to reach the deeper layers of the epidermis and dermis to exert its effects. Formulating the product with the aforementioned functional peptides can enhance the skin delivery efficiency of the functional peptides and maximize the overall utilization efficiency of the formulation system. This approach is widely used in serums designed to combat early signs of aging, brighten skin tone, and repair the skin barrier.Second, formulations containing high-molecular-weight bioactive ingredients.

Sprays and lightweight liquid formulations lack an oil phase to act as a delivery medium, causing active ingredients to remain on the skin's surface where they quickly evaporate and are lost. The addition of transdermal peptides can address the delivery limitations of these lightweight formulations by aiding the penetration of active ingredients in oil-free formulations, thereby expanding the efficacy potential of spray products.Fourth, scientific in vitro transdermal models. Cosmetic ingredient manufacturers and university research institutions frequently use it in in vitro Franz cell diffusion tests to evaluate the transdermal potential of various active ingredients, aiding in early-stage ingredient screening and preliminary formulation testing.
