For your practice, peptide skincare review starts with two questions: what is on the label, and what are you saying about the product? Begin with ingredient names. Then consider the finished product's intended use and the wording your team plans to repeat. This page covers label identification, claims and shelf decisions without making benefit claims for any ingredient.
What is peptide skincare?
Peptide skincare means topical skincare products whose ingredient lists include peptides, identified on labels by ingredient names. Use those names as your starting point when reviewing a line for your shelf. Match a familiar name in promotional materials to the ingredient name on the finished label.
The table below is a name reference. It does not describe what any ingredient does. Keep the full label available when preparing staff materials, so the team can identify the ingredient without attaching an unsupported explanation to it.
What do Matrixyl and palmitoyl pentapeptide-4 mean?
PubChem lists palmitoyl pentapeptide-4 as an INCI name, with Matrixyl identified as a trade mark and Pal-KTTKS as another synonym. These names are connected in the same compound record. Use that connection to answer a naming question, without turning it into a claim about a finished product.
How do Argireline and acetyl hexapeptide-8 relate?
PubChem lists acetyl hexapeptide-8 as an INCI name and Argireline as a synonym. Separately, its copper tripeptide-1 record lists GHK-Cu and prezatide copper. These records establish name relationships. Keep that identification task separate from deciding what your practice can say about a product containing the ingredient.
Is peptide skincare a cosmetic or a drug?
A product's intended use determines whether it is a cosmetic or a drug. Under the FD&C Act, cosmetics are intended for cleansing, beautifying, promoting attractiveness or altering appearance. Drugs include products intended to treat or prevent disease, or to affect the body's structure or function.
Intended use can come from labeling, advertising, internet content and other promotional materials. Claims can cause a product presented as a cosmetic to be considered a drug. Consumer perception, including a product's reputation, can also establish intended use. So can ingredients with a well-known therapeutic use. Gather the label and promotional materials together for this assessment.
The word "cosmeceutical" does not settle the question. The FD&C Act does not recognize it as a category, and the term has no legal meaning. If it appears in materials you receive, ask what intended use and claims sit behind that description.
Cosmetic products and ingredients do not need FDA approval before going on the market, except for color additives. MoCRA requires cosmetic facility registration and product listing, with certain small-business exemptions. Keep approval, registration and listing as separate questions. Ask the brand how it handles registration and listing, including any exemption it relies on.
What can your team say about peptide skincare?
Your team should keep cosmetic product wording within supported appearance claims. FDA distinguishes making lines less noticeable through moisturizing from claims about skin structure or function. It is concerned about drug claims on products presented as cosmetics. The examples below describe FDA's distinctions, not benefits attributed to any ingredient or product on this page.
Advertising has an evidence requirement as well as a claims boundary. Section 12 of the FTC Act prohibits false advertisements, including cosmetic advertisements. Health benefit or safety claims require competent and reliable scientific evidence. Animal or laboratory studies alone are not enough to substantiate those claims. Appearance language still needs to be truthful.
Testimonials and endorsements cannot carry claims that would be deceptive or unsubstantiated if the advertiser made them directly. Before repeating a testimonial, assess its actual message against the same standard you would apply to your own copy. A statement does not escape that review because someone else wrote it.
- Keep staff scripts, shelf cards and social posts within appearance language.
- Request the brand's approved claims and retain a copy as the team's reference.
- Check those claims against FDA's distinctions before adopting them.
- Do not compare a serum to injectable treatments.
Give the team a short set of reviewed sentences for product questions. If a proposed explanation goes beyond those sentences, verify it before adding it to practice materials. Apply this process to spoken explanations as well as written copy.
How do copper peptides relate to GHK-Cu?
PubChem lists copper tripeptide-1, GHK-Cu and prezatide copper in the same compound record. That name relationship does not establish a finished product's regulatory classification.
Assess the finished product's intended use, label and promotional claims. A product can be a cosmetic, a drug or both.
What should you look for when stocking peptide skincare?
Look for a finished, labeled cosmetic with a full ingredient list and appearance claims your team can assess before stocking it. Request the materials for the actual product you plan to carry. Use a finished cosmetic from the brand or its authorized professional channel as the basis for your shelf review.
What should you check on a peptide serum label?
Start with the full ingredient list, then compare the label's claims with the brand's approved wording. Keep copies together so your team has a clear reference when preparing a shelf card or answering a product question. Do not fill gaps with assumptions based on an ingredient name.
- Confirm that the item is a finished cosmetic, not raw peptide powder.
- Check that the label carries a full ingredient list.
- Retain the brand's approved appearance claims with the product label.
- Ask how the brand handles MoCRA facility registration and product listing, including applicable exemptions.
Resolve missing information before making the shelf decision. If you have a label but no claims reference, ask for the wording your team can assess. If the registration explanation relies on an exemption, ask the brand to identify it. Raw peptide powders are not finished skincare and do not belong on your cosmetic shelf.
Where does ZO Peptide Facial Refining Concentrate fit?
ZO Skin Health Peptide Facial Refining Concentrate is a professional skincare product listed in Portrait's Marketplace catalog. Its listing identifies a product your practice can review; this page makes no claim about what it does.
Use ZO's own approved claims as your reference and keep your practice's wording within appearance language. Retain the wording you adopt for staff explanations and shelf cards. The ZO Skin Health buying guide provides a separate guide for your practice's review of the line.
