A founder built a beautiful SPF 50 sunscreen and prepared to launch — only to discover their target market regulated it as a drug, not a cosmetic, with an entirely different set of testing and registration rules. The formula was fine; the market homework was not. At ubitglow, our belief is unchanged — a good product shouldn't need to build its own factory, and it shouldn't launch blind into a market's rules either. Here's how sunscreen formulation and regulation actually work.
Cosmetic or Drug? The Regulatory Split
Sunscreen's regulatory class is the single most consequential decision — and it varies by market.
Table: Sunscreen Regulation by Market
| Market | Classification | Key Framework |
|---|---|---|
| United States | OTC drug | FDA sunscreen monograph |
| European Union | Cosmetic | Regulation (EC) 1223/2009 |
| ASEAN | Cosmetic | ASEAN Cosmetic Directive |
| Japan | Quasi-drug | MHLW |
Data: The U.S. FDA regulates sunscreen as an over-the-counter drug under its monograph system, while the EU regulates sunscreen as a cosmetic under Regulation (EC) No 1223/2009 — two different frameworks with different testing, claims, and registration obligations.
Insight: The regulatory class determines everything downstream — testing, claims language, and manufacturing — so classify the market before you formulate, not after.

Mineral vs. Chemical UV Filters
The filter choice shapes the feel, the cast, and the safety story.
| Type | Filters | Behavior | Trade-off |
|---|---|---|---|
| Mineral | Zinc oxide, titanium dioxide | Reflect UV | Possible white cast |
| Chemical | Avobenzone, etc. | Absorb UV | Lighter feel |
Data: Mineral UV filters — zinc oxide and titanium dioxide — sit on the skin and reflect UV rays, and are generally gentler but can leave a white cast; chemical filters absorb UV and offer a lighter, more elegant feel.
Insight: Mineral filters carry a "clean" halo but demand formulation work to avoid the white cast, while chemical filters win on cosmetics elegance — the choice is a positioning and feel decision, not just an efficacy one.

SPF Testing and Claims
SPF is a measured number, not a marketing guess — and the claims must match the data. For how this fits into a broader product launch, see our skincare export regulatory guide and co-manufacturing guide.
| Element | Guidance |
|---|---|
| SPF number | Matches standardized testing |
| Broad spectrum | UVA + UVB protection |
| Water resistance | Tested and labeled |
| Claims | Restricted by market rules |
Data: SPF is measured by standardized testing that compares the UV dose required to cause redness on protected versus unprotected skin; the FDA requires specific testing and labeling for OTC sunscreen, including broad-spectrum and water-resistance claims.
Insight: SPF claims are legally constrained in the U.S. — the number on the bottle must be backed by testing, and unsupported claims are a compliance and liability risk, not just a marketing choice.

The OEM Manufacturing Path
Sunscreen manufacturing carries heavier testing and documentation than typical skincare.
- Classify the market — drug (US) or cosmetic (EU/ASEAN).
- Choose filters — mineral, chemical, or a hybrid.
- Run SPF testing — SPF, broad-spectrum, water resistance.
- Register and label — per the market's framework.
The Bottom Line
Sunscreen is where formulation meets regulation: classify the market first (OTC drug in the U.S., cosmetic in the EU), choose your filters for feel and positioning, and back every SPF claim with testing. Get the regulatory class right and the rest follows.
A good product shouldn't need to build its own factory — and it shouldn't launch blind into a market's rules either.
