What needs to be on a skincare product label?
A compliant US cosmetic label needs five core elements under 21 CFR Part 701: an identity statement, net quantity of contents, an ingredient list in descending order, the manufacturer, packer, or distributor's name and place of business, and warnings where required. MoCRA adds a sixth: an adverse-event contact line, in force since 29 December 2024.
The five elements come from the Federal Food, Drug, and Cosmetic Act and the Fair Packaging and Labeling Act, and they have been the rules for decades. MoCRA — the Modernization of Cosmetics Regulation Act of 2022 — did not rewrite them, but it raised the enforcement behind them: non-compliant products now face stop-distribution orders and mandatory recall authority. The label is also the first thing a retailer, a distributor, or a marketplace checks, so getting it right before printing is cheaper than reprinting it after.
Missing one element is a labeling violation. The five elements are not a menu — every cosmetic sold in the US needs all of them, in the right place, in the right order. The checklist at the end of this guide takes about two minutes per label.
The five core elements
Under 21 CFR Part 701, every cosmetic label sold in the US must contain the following, in the correct placement:
| Element | What it says | Where it goes |
|---|---|---|
| Identity statement | What the product is — "Moisturizing Cream", "Gentle Cleanser" | Principal display panel (front) |
| Net quantity of contents | Weight or volume in US units, with metric in parentheses | Bottom 30% of the principal display panel |
| Ingredient list | All ingredients in descending order, INCI names | Information panel (usually back) |
| Manufacturer identity | Name and place of business of manufacturer, packer, or distributor | Information panel |
| Warnings (as required) | For example "For external use only" where applicable | Information panel |
Two details catch founders most often. First, the identity statement must say what the product is — a pretty product name alone ("Lavender Dreams") is not an identity. Second, the net quantity must be in both US and metric units, in the bottom 30% of the front panel, with a minimum type size scaled to the label area: "Net Wt 4.5 oz (128 g)". Solids declare weight; liquids declare fluid volume. The jar's printed capacity is not your net weight — weigh the filled product.
The MoCRA contact line
MoCRA added one new line that most labels still miss. Under FD&C section 609(a), in force since 29 December 2024, every cosmetic label must carry a US address, US phone number, or website or email address through which the responsible person can receive adverse-event reports. A website or email address is enough — the line does not have to be a street address — but it must be a way for a customer to reach you about a reaction.
The detail that matters for small brands: the $1M small-business exemption covers facility registration and product listing — not this line. A one-person brand with $8,000 of annual sales still needs the contact line on every label. MoCRA also added facility registration and product listing on top of the label rules: new products must be listed with the FDA within 120 days of first marketing, with the product name, category, ingredient list, and the responsible person's contact information. The MoCRA rules guide for spas and the brand-owner duties guide cover registration and listing; the MoCRA checklist tool walks through both.
The ingredient list, in detail
The ingredient list is where most labels fail, and the rule is simple once stated: list every ingredient in descending order of predominance, using INCI (International Nomenclature of Cosmetic Ingredients) names (21 CFR 701.3). Ingredients at 1 percent or below may follow in any order, color additives go last, and fragrance blends may be declared simply as "Fragrance". The single most common failure is listing ingredients in recipe order — the order they were added to the batch — instead of by weight in the finished product.
Get the list from your manufacturer, not from your recipe sheet. The manufacturer holds the finished formula with the final percentages, and they should supply the INCI-ordered list as part of the label artwork package — ask for it in writing before artwork starts, because a label designed around a wrong list is a label that gets reprinted. If the formula changes after the label is printed — a supplier swap, a preservative change — the list changes too, and the label needs a new run. Budget for that possibility in the labels and printing costs guide.
What you say decides which rules apply
Everything depends on one question: what does the label claim the product does? Say "moisturizing", "exfoliating", "soothing", or "deodorizing" and the product is an FDA cosmetic — the full checklist in this guide applies. Say "treats eczema", "treats acne", "antibacterial", or "SPF" and it is a drug, and none of this checklist is enough: drugs need an OTC monograph and a different set of rules entirely. Say nothing about what it does and sell it only as soap — saponified oils, cleaning by the alkali-fatty-acid salts, sold only as soap under 21 CFR 701.20 — and it is true soap, exempt from FDA cosmetic regulation, with an ingredient list that is optional rather than required.
The same logic applies to "natural" and "organic". The FDA does not define or regulate either term for cosmetics, but the label must still be truthful and not misleading — a "natural" claim does not exempt a product from any labeling rule, and it does not make a drug claim into a cosmetic one. Write claims for what the product actually does, in words you can support, and keep the clinical language off the label unless you can support it with testing. When in doubt, use the milder claim: a cosmetic claim that understates the product is safe, while a drug claim that overstates it is a violation. The testing package guide covers what claim-support testing looks like.
The pre-print checklist
Walk down this list with the label artwork in front of you, before it goes to print. Each point cites the rule it comes from.
- Identity, on the front. The product says what it is — "Moisturizing Cream", "Gentle Cleanser" — on the principal display panel (21 CFR 701.11). A pretty name alone is not an identity.
- Net contents, dual units, bottom 30%. "Net Wt 4.5 oz (128 g)" — both US and metric units, in the bottom 30% of the front panel (21 CFR 701.13; FPLA). Solids declare weight; liquids declare fluid volume.
- Ingredient list in the legal order. INCI names, descending order of predominance; ingredients at 1% or below may follow in any order; color additives last; fragrance may be declared as "Fragrance" (21 CFR 701.3).
- Manufacturer or distributor identity. Name and place of business of the manufacturer, packer, or distributor — or "distributed by" with your business name and contact details.
- The MoCRA contact line. A US address, US phone number, or website or email for adverse-event reports (FD&C §609(a)). The small-business exemption does not cover this line.
- Warnings where required. "For external use only" and any warnings tied to specific ingredients or product types (21 CFR 740.10, 740.11).
- Country of origin, if imported. Imported products need country-of-origin marking, such as "Made in India", to satisfy US Customs requirements.
When the checklist passes, the label is ready for print — and the product is ready for the shelf.
