Peptides are one of the skincare world’s most versatile and high-performance ingredients. These tiny chains of amino acids act as messengers that signal your skin to repair, strengthen, and renew itself — helping improve texture, reduce visible blemishes, and support overall skin health.


Medik8 has long been a leader in peptide technology, and their newest launch, Niacinamide Peptides, combines the power of 10% niacinamide with targeted peptides and N‑Acetyl Glucosamine (NAG) to deliver clarity, refinement, and barrier support. Whether you’re new to peptides or already a fan, here’s everything you need to know about this clinically proven formula, and how it compares to other peptide-powered Medik8 products.

What Are Peptides and Why They Matter


Peptides are short chains of amino acids, the building blocks of proteins like collagen and elastin. They help your skin:

  • Support structural integrity

  • Refine texture and minimize pores

  • Reduce visible redness and inflammation

  • Improve overall skin resilience

Using peptides consistently can help your skin look smoother, healthier, and more radiant over time.
