Oligopeptide-10 is a short-chain peptide containing 15 amino acids with strong antibacterial properties, especially effective against Propionibacterium acnes and reducing inflammation. When used in combination with salicylic acid, it can dilate pores and enhance the therapeutic effect. Its unique antibacterial mechanism makes it difficult for bacteria to develop drug resistance, making it suitable for treating acne and helping sensitive skin repair and strengthen the skin barrier.
