What is Caprooyl Tetrapeptide-3 Powder?
Xi'an Faithful BioTech Co., Ltd. is situated in Xi'an, the birthplace of the ancient Silk Road. Leveraging the city's mature logistics network and abundant fine chemical industrial resources, our enterprise has grown into an integrated fine chemical provider that delivers products to global partners. As the acetate salt form, Caprooyl Tetrapeptide-3 Powder carries CAS No.1012317‑71‑3. It is a popular biomimetic lipophilic signal peptide for skincare, with the sequence hexanoyl‑lysine‑glycine‑histidine‑lysine‑amide. The raw material occurs as white to off‑white crystalline powder, whose HPLC purity generally falls between 95% and 98%. Thanks to its excellent water solubility, it can be blended with numerous skincare actives. Working on the dermal‑epidermal junction zone, it facilitates the generation of essential structural substances: type VII collagen, laminin‑5 and fibronectin. It reinforces skin interlayer bonding, eases skin sagging, boosts skin firmness and softness, fades fine lines, and calms skin pressure from outside surroundings. It is also regularly incorporated into skincare products focusing on texture improvement.
What are the applicable research scenarios for Caprooyl Tetrapeptide-3 Powder?
Serving as a biomimetic signal‑peptide skin‑care raw material, Caprooyl Tetrapeptide-3 Powder (CAS 1012317‑71‑3) finds broad application in multiple external skin‑care formulas including serums, creams and lotions. Formulators are advised to adopt a dosage of 100‑500 ppm. It mixes well with most skin‑care components. By reinforcing the dermal‑epidermal junction, it enhances skin elasticity and firmness and diminishes fine lines. Additionally, it alleviates skin pressure brought on by outside environmental conditions and fits well within formulas dedicated to skin texture improvement.

Caprooyl Tetrapeptide-3 Powder (CAS 1012317-71-3) is a synthetic biomimetic peptide skincare ingredient. At the recommended concentration in the formula, it exhibits good skin tolerance with a low risk of irritation and sensitization. It is minimally absorbed through the skin and is suitable for various skin types, including sensitive skin. It can be safely used in leave-on skincare products. The ingredient itself is non-comedogenic and can be combined with most skincare active ingredients. Only a very small number of people with extremely poor skin tolerance may experience mild discomfort. It is only suitable for external skincare applications.
What is the mechanism of action of Caprooyl Tetrapeptide-3 Powder?
Functioning as a skin‑signaling peptide, Caprooyl Tetrapeptide-3 Powder imitates endogenous skin messenger molecules and delivers modulatory signals to cells located within the dermal‑epidermal junction.
This bioactive component stimulates elevated synthesis of type VII collagen, which reinforces the dermal‑epidermal junction and mitigates structural loosening between skin layers.
It boosts the biosynthesis of laminin‑5 as well as fibronectin, optimizing the protein profile of the basement membrane and stabilizing the basal skin framework.
Reinforced inter‑layer skin connections help alleviate skin laxity, smooth fine surface lines, and contribute to firmer, more supple skin texture.
Its efficacy relies on cellular signal transduction rather than deep skin penetration; functional performance takes place at the skin surface and dermal‑epidermal junction zones.
