Peptides

Peptides are the premier collagen-boosting ingredients in 2025, driving 180% year-on-year sales growth in multi-peptide serums. They signal skin to produce collagen, elastin, and hyaluronic acid, outpacing #4 retinol in versatility by also targeting hydration while retinol primarily focuses on cell turnover. Brands like Ordinary, Paula's Choice, and Augustinus Bader led this surge, with peptide formulations now comprising 28% of all anti-aging product launches this year.
