With new skincare trends constantly hitting the shelves, it’s hard to know what’s truly effective and what’s just a passing fad. One ingredient that’s been making waves is peptides—but what exactly are they, and do they live up to the buzz? In this installment of our Dermatologist’s Take series, we asked Dr. Fricke to weigh in on the science behind peptides in skincare, how they work, and whether they’re a must-have in your daily routine.
What are peptides, and how do they work in skincare?
Dr. Fricke: Peptides are short chains of amino acids—the building blocks of proteins like collagen, elastin, and keratin, which are all crucial for maintaining the skin’s structure, strength, and firmness. In skincare, peptides act as messengers, signaling your skin to perform specific functions like producing more collagen or repairing damage. Think of them as gentle nudges to your skin cells, encouraging them to behave like their younger, more resilient selves.
What skin concerns can peptides help improve?
Dr. Fricke: Peptides are multitaskers. Here’s what they can help with:

When should I start using peptides in my skincare routine? Can I use peptides with other active ingredients like vitamin C or AHAs?
Dr. Fricke: You can start using them in your mid-20s to early 30s as a preventative measure, or later to help restore firmness and reduce signs of aging.
And yes—peptides play well with others. You can use them with:
