What does a beauty, skincare or supplement brand need from an Amazon agency? Three things most agencies treat as an afterthought: claims that stay inside FDA and Amazon rules, content that earns trust in a category full of lookalikes, and repeat purchase built through Subscribe and Save and reliable stock. Marknology runs all three as one team, with our own Kansas City warehouse for dated products.

Because the rules are stricter and shoppers are more skeptical. The mistakes that cost the most here are rarely about advertising.
The FDA says a product's intended use decides whether it is a cosmetic or a drug. Say a cream treats a condition and the law can treat it as a drug. Supplements follow a different rulebook, where structure and function claims are allowed and disease claims are not.
The Modernization of Cosmetics Regulation Act of 2022 (MoCRA) requires cosmetic facility registration and product listing with FDA, with some small business exemptions, and serious adverse event reporting within 15 business days.
Amazon can ask for approval before you list in parts of Beauty, including recent manufacturer invoices. Supplements must pass testing or verification by an approved Testing, Inspection and Certification (TIC) organization.
Shoppers compare ingredients, textures and reviews across dozens of similar products. Images, video and A+ Content have to show the product honestly and answer the questions reviews keep asking.
Serums, cleansers and daily supplements run out. Subscribe and Save, bundles and never running out of stock matter more than one big launch month.
Many beauty products need an expiration date or a Period After Opening (PAO) symbol, and FBA has rules for expiration-dated products. Old stock at Amazon becomes a removal or a write-off.

The two share shoppers and a lot of tactics, but the rules underneath are different.
| Beauty and skincare | Dietary supplements | How we handle it | |
|---|---|---|---|
| Main US rulebook | FDA cosmetic rules, updated by MoCRA | FDA dietary supplement rules | We work from the rules that apply to your product, not a generic template |
| Claims that get listings removed | Treating or preventing a condition | Diagnosing, treating, curing or preventing a disease | Claims check against Amazon policy, then your sign-off |
| Before you can sell | Approval and documents in some subcategories; hazmat review for some formulas | Testing or verification by an approved TIC organization | We plan these steps into the launch timeline |
| What converts | Texture, shade and application images, ingredient clarity, video | Label clarity, serving and sourcing detail, third-party test proof | Listings, A+ Content and video made in house |
| Repeat purchase | Replenishment and gift sets | Monthly use and bundles | Subscribe and Save, bundles and restock planning |
| Stock handling | Expiration date or PAO symbol where required | Lot numbers and expiration dates | Lot and expiration tracking, earliest-dated stock first |

See the Growth DiagnosticLook for an agency that checks every claim before it goes live, knows the category approval and documentation steps, and can build content that earns trust without overpromising. Ask how they handle expiration dating, Subscribe and Save and counterfeit sellers, because those decide whether a beauty or supplement brand keeps its margin.
Be careful. Under FDA rules a product's intended use decides whether it is a cosmetic or a drug, and claims to treat or prevent a condition can make a cosmetic a drug in the eyes of the law. Amazon also removes listings that make drug claims without the right approvals, so copy should describe what the product does for the look and feel of skin.
Yes. Amazon requires dietary supplements to be tested or verified by an approved Testing, Inspection and Certification organization, in addition to meeting FDA rules for manufacturing and labeling. Build that step into your launch timeline, since it can take weeks.
Many do. Amazon's beauty seller guidance says products should carry expiration dates or a Period After Opening symbol where regulations require it, and FBA has its own rules for expiration-dated products. Our warehouse records lot numbers and expiration dates on receipt and ships the earliest-dated stock first.
Yes, for products stored at room temperature. Our Kansas City warehouse handles FBA prep and shipments, is approved for Seller Fulfilled Prime and ships same day on orders received by noon Central. We do not offer refrigerated, frozen or other cold chain storage.
You do. We write listings and content, run a check against Amazon policy for risky claims, and send the copy to you for approval before anything goes live. For some products Amazon asks for documents first, and we collect those with you.
