Product description
This cosmetic peptide ingredient eliminates acne-causing bacteria through a physical membrane-disruption mechanism, providing effective antimicrobial activity without promoting bacterial resistance. The positively charged peptide selectively binds to negatively charged components on the surfaces of Cutibacterium acnes and Staphylococcus aureus, disrupting bacterial cell membranes and causing rapid cell lysis through osmotic imbalance. Unlike antibiotics that inhibit intracellular enzymes, this membrane-targeting mechanism greatly reduces the risk of resistance development during long-term use. With a low minimum inhibitory concentration (MIC), it efficiently removes acne-causing bacteria within pores, helping improve inflammatory papules, pustules, recurrent breakouts, and comedones. When combined with 0.5% salicylic acid, clinical studies have demonstrated a 40% greater improvement in inflammatory acne and comedones after 28 days compared with benzoyl peroxide alone, while providing superior skin tolerance.
The ingredient also exhibits potent anti-inflammatory activity by suppressing bacteria-induced inflammatory cytokines, including IL-6 and TNF-α, rapidly reducing acne-associated redness, swelling, tenderness, and discomfort. It helps repair barrier irritation caused by acne treatments such as exfoliating acids, retinoids, and benzoyl peroxide, making it particularly suitable for long-term care of oily, acne-prone, and sensitive skin while reducing persistent post-acne erythema.
In addition, the peptide supports dermal repair by activating the TGF-β signaling pathway in fibroblasts, promoting the synthesis of type I and type III collagen, elastin, and glycosaminoglycans while inhibiting matrix metalloproteinase-1 (MMP-1). This helps improve superficial acne scars, uneven skin texture, and dehydration-related fine lines while supporting overall dermal regeneration.
The ingredient further strengthens the epidermal barrier by promoting filaggrin synthesis, reinforcing corneocyte cohesion, and reducing transepidermal water loss (TEWL). It also helps maintain a balanced skin microbiome by suppressing excessive proliferation of harmful bacteria while preserving beneficial microorganisms, improving oily yet dehydrated skin and reducing the recurrence of acne associated with barrier dysfunction.
Beyond facial skincare, the peptide offers deodorizing benefits through metal ion chelation. By binding iron and copper ions involved in sweat oxidation, it helps inhibit the formation of malodorous fatty acid oxidation products, making it suitable for deodorants, antiperspirants, and body acne care formulations with a mild, non-irritating odor-control effect.
With its small molecular size and excellent skin compatibility, the ingredient is suitable for acne-prone skin, sensitive skin, and post-procedure skin without causing muscle paralysis, dependency, or rebound breakouts after discontinuation. Manufactured under standardized GMP-compliant cleanroom conditions, it is supplied with complete quality control and regulatory documentation. It is ideal for cosmetic formulations targeting acne control, sebum regulation, skin repair, and body deodorizing applications.
