Enhancing results: The role of peptides in aesthetic procedures

In the evolving world of aesthetics, peptides are quickly gaining attention for their powerful role in skin regeneration and repair. Once primarily associated with topical skincare, bioactive peptides are now being integrated into clinical treatments designed to enhance outcomes at a cellular level. These short chains of amino acids act as biological messengers, signaling to the skin to produce collagen, improve elasticity, reduce inflammation and accelerate healing, making them an increasingly valuable tool in modern aesthetic practices.

What truly sets peptides apart is their ability to work intelligently with the body's natural processes. Different peptides are designed to target specific concerns, from strengthening the skin barrier to improving pigmentation to reducing fine lines. Today, peptides are being used alongside injectables, laser treatments, microneedling and post-procedural care to support recovery and optimize results. And as research advances, more applications will continue to emerge within skin rejuvenation and overall wellness.

But what are peptides, and what do they do? What are the most used peptides within the aesthetics field? What continued advancements are on the horizon for this exciting innovation? To learn more about peptides and the exciting role that they can play in the world of aesthetics, we reached out to ASPS Member Surgeon Johnny Franco, MD.

The booming popularity of peptides

While many innovations are driving the growing popularity of peptides among patients and surgeons alike, one area has truly reigned supreme – the success of GLP-1 medication.

"The GLP-1 era brought millions of patients into 'metabolic medicine,' and peptides got pulled into the same conversation," said Dr. Franco. "At the same time, the regulatory framework for compounding peptides is complicated."

Growing popularity supports further integration of peptides into aesthetics, but a few roadblocks remain, primarily related to availability and use.

"A prescriber briefing from the Alliance for Pharmacy Compounding explains the core issue," said Dr. Franco. "Many peptides were reclassified in March 2020 by federal law as biologics, and traditional 503A compounding pharmacies cannot compound substances classified as biologics."

The basics of peptides within aesthetics

Before diving into how peptides are being implemented within aesthetics, it's important to understand how they work.

"Cosmetic peptides are classified into four main functional categories based on their mechanisms of action," said Dr. Franco. "Signal peptides (stimulating collagen and extracellular matrix synthesis), carrier peptides (delivering trace minerals like copper), neurotransmitter inhibitor peptides (reducing muscle contraction for wrinkle reduction) and enzyme inhibitor peptides (blocking collagenase, elastase and tyrosinase to prevent aging and pigmentation)."

While it may feel like there is an abundance of peptides available to plastic surgeons, it's important to remember that each serves a different purpose in the body.

"These peptides demonstrate diverse claimed activities, including increasing collagen and hyaluronic acid production, modulating pigmentation, maintaining skin microbiome health, providing antioxidant effects and delivering anti-inflammatory benefits," said Dr. Franco.

A growing list of benefits reflects the broader momentum peptides are gaining across medicine and research.

"Over 60 peptide drugs are currently approved in major markets, with more than 150 in active clinical development," said Dr. Franco. "The most frequent medical indications include oncology, metabolism and endocrinology."

 Specific examples include:

• Metabolic diseases: Liraglutide and semaglutide for type 2 diabetes and obesity, linaclotide for irritable bowel syndrome
• Oncology: Goserelin for prostate and breast cancer, sipuleucel-T as the first peptide-derived vaccine against prostate cancer
• Endocrine disorders: Lanreotide and octreotide (somatostatin analogues) for acromegaly
• Antimicrobial applications: Antimicrobial peptides (AMPs) showing promise against multidrug-resistant organisms

One area of particular excitement around peptides in this industry is regenerative aesthetics.

"Regenerative peptides are gaining attention for enhancing surgical recovery and tissue regeneration in plastic surgery, but rigorous clinical trials are lacking," said Dr. Franco. "While preclinical studies show promise and safety profiles appear favorable, the paucity of human studies highlights an urgent need for high-quality research. Plastic surgeons are well-positioned to lead investigations integrating regenerative peptides into perioperative care and evaluating their ability to optimize outcomes in aesthetic procedures."

Future applications of peptides within aesthetics

Looking towards innovations in peptides within aesthetics, the future is bright.

"We're seeing a wellness wave and a focus on how we can maximize recovery post-procedure," said Dr. Franco. "With this, we're going to start seeing some actual studies and how peptides can help with the recovery process."

This increased focus on peptides and how they can better support patients in aesthetics also extends to future applications, particularly how peptides are delivered into the body.

"Emerging nanocarrier delivery systems aim to improve peptide stability, absorption, and half-life," said Dr. Franco.

Additionally, there is potential for integrating artificial intelligence (AI) to improve research and peptide optimization in aesthetics.

"The integration of artificial intelligence has accelerated peptide discovery, enabling rapid identification of bioactive sequences and structural optimization to enhance stability, efficacy and target specificity," said Dr. Franco.

As aesthetic medicine continues to move towards more biologically driven solutions, peptides are playing an increasingly important role in enhancing treatment outcomes and overall well-being. By supporting collagen production, cellular repair and skin resilience, peptides offer a powerful way to amplify both in-office procedures and long-term skin health. With ongoing innovation and expanding applications, these bio-active compounds are poised to become a cornerstone of next-generation aesthetic treatments, helping patients achieve stronger, healthier and more radiant skin.
