After years of testing every cult-favorite peptide serum, New York Post commerce journalist Victoria McDonnell shares her top picks for the best peptide serums that actually deliver results, from budget-friendly options to luxury splurges.

Why it matters

Peptide science isn't just beauty buzz; studies show that peptides can stimulate collagen synthesis, enhance skin cell activity and even reduce inflammation, making them one of the most exciting classes of ingredients in skincare today. Consumers are opting for these affordable, multi-targeted therapies as traditional office-based treatments can be significantly more expensive.

The details

McDonnell tested a wide range of peptide serums on different skin types and concerns, evaluating factors like efficacy on skin hydration, absorption rate, sensitivity and irritation, texture and consistency, and visible results on skin firmness. She found that the best peptide serums don't work overnight miracles, but they do help coax skin into looking firmer, smoother and more resilient over time.
