Face serum label requirements
A plain face serum is a cosmetic, so it follows the standard FDA and FPLA cosmetic-label rules. The catch is specific to serums: the marketing claims that sell them — anti-aging, firming, collagen-boosting — are exactly the claims that can turn a cosmetic into an unapproved drug.
What a face serum label needs
| Element | Governing standard |
|---|---|
| Statement of identity ("Face Serum") | 21 CFR 701.11 |
| Net quantity of contents | 21 CFR 701.13 / FPLA |
| Name & place of business | 21 CFR 701.12 / FPLA section 4(a) |
| Ingredient declaration (INCI) | 21 CFR 701.3 |
| MoCRA adverse-event contact | FD&C Act section 609 |
| Warnings / safe use (as needed) | 21 CFR 740 |
| Prop 65 (California only) | 27 CCR 25603 |
Net quantity: serums are usually a fluid measure
Most serums are pourable liquids, so the FPLA declares them by fluid measure, not weight, for example 1 fl oz (30 mL). A thick, non-pourable serum or oil-gel may be declared by weight instead. Either way, give US customary and metric units (US first) in the bottom 30% of the principal display panel. Full cosmetic checklist →

The serum trap: when a claim makes it a drug
Under the FD&C Act, what a product is intended to do determines how it is regulated. A cosmetic (FD&C Act section 201(i)) is intended to cleanse or beautify. A product intended to affect the structure or function of the body, or to treat a condition, is a drug (FD&C Act section 201(g)). Serum claims slide across that line easily:
- Cosmetic-safe — "hydrates," "improves the look of skin," "smooths the appearance of fine lines," "adds radiance."
- Drug territory — "stimulates collagen production," "repairs the skin barrier," "treats acne," "reverses sun damage," or any SPF claim.
A drug claim makes the serum an unapproved new drug unless it follows the applicable drug requirements, and an SPF serum needs a Drug Facts panel under the sunscreen monograph. The safest approach is to describe appearance, not biological change.
Ingredients, in INCI / descending order
List every ingredient by its INCI (common or usual) name in descending order of predominance, with the relaxation for ingredients at 1% or less and color additives (21 CFR 701.3). A water-based serum usually begins with Aqua/Water; an oil serum begins with its carrier oils. How INCI order works →
Tiny dropper bottles: small-package placement
Serum bottles are small, so FDA-recognized accommodations apply: required information may go on the bottle, the carton, or an attached tag, and the ingredient list in particular may appear off-pack (a card, or a website for online and mail order) as long as the consumer can find it at purchase. Keep the statement of identity and net quantity on the package wherever possible. The MoCRA contact requirement →

Is a face serum a cosmetic or a drug?
A serum that only cleanses or beautifies is a cosmetic (FD&C Act 201(i)). If it claims to affect the structure or function of the body or to treat a condition, for example boosting collagen or repairing the skin barrier, it is a drug (FD&C Act 201(g)) and must meet drug requirements. The claim, not the formula, decides it.
Is face serum net quantity given by weight or volume?
Most serums are pourable liquids, so the FPLA declares them by fluid measure, such as 1 fl oz (30 mL). A thick, non-pourable serum may be declared by weight. Give US customary and metric units in the bottom 30 percent of the front panel.
What ingredient list does a face serum need?
A full ingredient declaration in INCI names, in descending order of predominance, with the relaxation for ingredients at 1 percent or less and color additives (21 CFR 701.3). A water-based serum usually starts with Aqua; an oil serum starts with its carrier oils.
How do I fit the label on a small serum bottle?
FDA allows practical placement: information can go on the bottle, the carton, or an attached tag, and the ingredient list may appear off-pack on a card or, for online and mail order, a website. Keep the statement of identity and net quantity on the package where possible.
