Product description
This bioactive cosmetic peptide ingredient activates the skin's innate defense system by stimulating the endogenous production of human β-defensins (hBD-2 and hBD-3), enhancing natural skin immunity through a biomimetic mechanism. Rather than directly killing bacteria, it helps regulate the skin microbiome by strengthening the skin's own antimicrobial defense, effectively inhibiting the proliferation of acne-associated bacteria without promoting bacterial resistance. Long-term use helps reduce recurrent breakouts and restore microbial balance in oily, acne-prone skin.
The ingredient regulates sebaceous gland activity, reducing excessive sebum production and minimizing pore blockage caused by excess oil. By maintaining a healthy balance between beneficial and pathogenic microorganisms, it helps improve persistent oiliness, comedones, and acne-prone conditions.
Its broad-spectrum anti-inflammatory activity downregulates pro-inflammatory cytokines, including IL-6 and TNF-α, rapidly relieving redness, swelling, burning, and discomfort associated with acne. It also helps minimize post-inflammatory hyperpigmentation (PIH) by reducing inflammation-induced melanogenesis, making it an ideal soothing component for formulations containing high-concentration acids, retinoids, or skin-brightening ingredients.
The ingredient further strengthens the epidermal barrier by upregulating filaggrin and tight junction proteins, reducing transepidermal water loss (TEWL) and improving dehydration-related roughness and flaking. Mild stimulation of fibroblast activity promotes type I and type III collagen synthesis while helping inhibit matrix metalloproteinases (MMPs), improving fine dehydration lines and supporting the recovery of superficial skin damage following minimally invasive cosmetic procedures.
Designed for sensitive skin, the ingredient is acid-free, hormone-free, and non-photosensitizing, with excellent skin compatibility demonstrated through patch testing. It is suitable for long-term use on acne-prone, sensitive, post-procedure, and delicate skin, including the periorbital area. It does not cause muscle paralysis, dependency, or rebound redness and breakouts after discontinuation.
Manufactured under standardized GMP-compliant cleanroom conditions, the ingredient is supplied with complete quality control and regulatory documentation. It is suitable for the development of cosmetic formulations targeting oil control, acne care, sensitive skin maintenance, post-procedure recovery, and early anti-aging applications.
This product is intended solely as a cosmetic ingredient for external use. It is not intended for oral administration or subcutaneous injection.
