- For mild to moderate active acne, topical peptide serums containing GHK-Cu, Matrixyl, Oligo Peptide-10, and Palmitoyl Tetrapeptide-7 provide meaningful benefits with minimal complexity. For moderate to severe acne with significant scarring, a combined approach using daily topical peptides plus periodic injectable peptides (BPC-157, TB-500) addresses both surface and deep-tissue healing. For antibiotic-resistant acne, emerging antimicrobial peptides and KPV offer alternatives that work through mechanisms resistant to bacterial adaptation. The choice is not either/or. Many people start with topical formulations, see partial improvement, and add targeted injectable peptides to address what topical delivery alone cannot resolve. Getting started with peptides provides a comprehensive overview for anyone new to peptide use, regardless of the delivery method chosen.
