Peptides for Skin & Wellness: Are They Safe? A Nurse Practitioner Explains

Kasey Bennett, FNP-BC

If you’ve been Googling peptides for skin, NAD+ patches, BPC-157 benefits, or GHK-Cu for collagen, you’re not alone. Peptide therapy is one of the fastest-growing trends in cosmetic dermatology and regenerative wellness. At Hi, Finch Cosmetic Dermatology, it’s one of the most common topics patients ask about.

So let’s talk about it — what peptides are, how peptide therapy works, and how to make sure the peptides you’re using are safe.

What Are Peptides?

Peptides are short chains of amino acids, which are the building blocks of proteins. In the body, peptides act as signaling molecules — essentially sending instructions to cells. Depending on the type, peptides can help stimulate collagen production, support tissue repair, reduce inflammation, and improve cellular energy.

In cosmetic dermatology and aesthetic medicine, peptides are commonly used for:

  • Skin rejuvenation

  • Collagen stimulation

  • Anti-aging treatments

  • Tissue repair support

  • Cellular energy optimization

You’ll find peptides in skincare products, injectables, oral supplements, and increasingly, transdermal peptide patches.

While the science behind peptides is promising, safety and sourcing are critical.

Are Peptides Safe?

The safety of peptide therapy depends heavily on where the peptides are sourced and how they’re compounded.

Many peptides sold online are labeled “for research use only.” These products are not regulated for human consumption and may contain inaccurate dosing, impurities, or inconsistent formulations. Even if the ingredient itself has research behind it, poor manufacturing standards can make it unsafe.

Safe peptide therapy should include:

  • Pharmaceutical-grade ingredients

  • Compounding through a licensed pharmacy

  • Sterile preparation when required

  • Batch testing for purity and potency

  • Medical screening and supervision

Here’s a key tip:

If you are getting peptides from any provider, ask what kind of pharmacy they are coming from.

Are they sourced from a licensed U.S. compounding pharmacy? Are the ingredients tested? Is the provider transparent about their supply chain? A reputable medical practice should always be able to answer these questions clearly.

If they can’t — that’s a red flag.

NAD+ Patch, BPC-157 & GHK-Cu at Hi, Finch Cosmetic Dermatology

At Hi, Finch Cosmetic Dermatology, we offer The Push Patch NAD+ 250mg / BPC-157 2000mcg / GHK-Cu 10mg transdermal patch. These peptide patches are compounded through a licensed pharmacy that follows strict regulatory and quality-control standards.

Here’s why these ingredients are so popular in regenerative and aesthetic medicine:

NAD+ (250mg)

NAD+ (nicotinamide adenine dinucleotide) is essential for mitochondrial function and cellular energy production. NAD+ levels naturally decline with age, which is why NAD+ therapy has become increasingly popular for longevity and wellness support.

BPC-157 (2000mcg)

BPC-157 is a peptide studied for its potential role in tissue repair and inflammation support. While research continues, it has gained attention in regenerative medicine.

GHK-Cu (10mg)

GHK-Cu is a copper peptide widely used in dermatology for collagen production, skin firmness, and overall skin rejuvenation.

Because our NAD+ peptide patches are pharmacy-compounded, patients receive:

  • Verified purity and safety

  • Consistent dosing

  • High-quality ingredient sourcing

  • Medical evaluation before use

  • Ongoing professional supervision

Why Pharmacy-Compounded Peptides Matter

When considering peptide therapy for skin rejuvenation or anti-aging support, quality matters more than marketing. Compounding pharmacies that follow regulatory standards use validated raw materials, sterile processing techniques, and batch testing to ensure safety and consistency.

Purchasing peptides from unverified online sources increases the risk of contamination, under-dosing, overdosing, or exposure to unknown additives.

Peptide therapy should never be guesswork.

The Bottom Line on Peptides for Skin and Wellness

Peptides can be powerful tools in cosmetic dermatology, regenerative medicine, and cellular health — when used responsibly. The key is medical oversight and sourcing from licensed compounding pharmacies.

At Hi, Finch Cosmetic Dermatology, our approach to peptide therapy and NAD+ patches is grounded in safety, transparency, and evidence-based care.

If you’re considering peptides for anti-aging, skin rejuvenation, or overall wellness support, we’re here to help you make informed, safe decisions.

Because when it comes to peptide therapy, it’s not just about what’s trending — it’s about what’s trusted, tested, and professionally guided.
