Acetyl Tetrapeptide-3 Basement Membrane Builder: Reconstructs Dermal-Epidermal Junction via Laminin-5 and Collagen VII Stimulation

Acetyl Tetrapeptide-3 is a bio-mimetic peptide composed of four amino acids that mimics natural peptides in the human body. It stimulates cell proliferation and differentiation, improves hair follicle structure, regulates the hair follicle cycle, and promotes follicular development. Simultaneously, it repairs and strengthens the connection between the epidermis and dermis. It enhances hair anchoring stability, reducing hair loss caused by weak connections.

Acetyl Tetrapeptide-3 accelerates the formation of extracellular matrix (ECM) proteins such as desmoglein, collagen III, and collagen VII, thereby effectively improving hair follicle structure and enhancing hair anchoring stability. As Acetyl Tetrapeptide-3 is a peptide synthesized from amino acids, it poses no side effects with long-term use on humans, making it highly suitable for sustained treatment of hair loss. It also offers dual application value in personal care:

(1) Hair and Eyelash Care: As a core active ingredient, it is widely used in anti-hair loss serums, eyelash growth solutions, and eyebrow care products. It promotes the regeneration of eyelashes and eyebrows, builds a stronger cellular matrix around the dermal papilla, improves hair anchoring, and reduces shedding. When combined with Biotinoyl Tripeptide-1 and plant extracts, it synergistically achieves longer, denser, and more resilient-looking lashes and brows.

(2) Skin Care & Anti-Aging: As a peptide skin conditioner, it is incorporated into anti-wrinkle and anti-aging skincare products. It stimulates the synthesis of key extracellular matrix components in the scalp and skin, enhancing structural support, improving skin texture, and boosting firmness.

• (1) Promoting Hair Growth and Strengthening: Acetyl Tetrapeptide-3 stimulates dermal papilla cells to synthesize extracellular matrix proteins, specifically:

  Type III collagen expression increases by 65%, providing more robust structural support for hair follicles.

  Laminensin expression increases by 285%. This significant boost in the anchoring protein strengthens the ECM network, firmly anchoring hair within the follicle.

  By increasing hydroxyproline, Type III collagen, and laminensin, it effectively improves follicle size and hair retention, reducing age-related hair loss. This results in denser, smoother, and more secure eyebrows and hair.

  (2) Scalp Inflammation Suppression: Beyond promoting growth, this ingredient helps inhibit scalp inflammation, creating a healthy microenvironment for hair development.

  (3) Anti-Wrinkle & Skin Firming: In skincare applications, Acetyl Tetrapeptide-3 stimulates synthesis of key ECM components, reinforcing the dermal-epidermal junction (DEJ) structure to reduce wrinkle formation and enhance skin firmness.

  (4) Clinical Research Support: In a 24-week randomized controlled trial for androgenetic alopecia, a compound containing Acetyl Tetrapeptide-3 (combined with Chickpea Sprout Extract A and Ginseng Extract) demonstrated therapeutic efficacy comparable to 3% minoxidil solution.
