TL;DR:
- Small skincare brands often avoid SPF labels due to high testing costs and regulatory hurdles.
- Non-nano zinc oxide provides effective broad-spectrum protection, but SPF claims require clinical testing.
- Transparency, clear zinc percentages, and proper application guidance build trust over SPF labeling.
Most people assume that if a product protects your skin from the sun, it must carry an SPF number. That assumption is understandable, but it misses a lot of what actually happens behind the scenes for small, natural skincare makers. The truth is that many high-zinc balms and tallow-based formulas offer real, meaningful UV protection without ever printing an SPF rating on the label. The reasons behind that choice are rooted in cost, regulation, and a commitment to staying honest about what a small-batch brand can realistically do.
Key Takeaways
| Point | Details |
|---|---|
| SPF testing is costly | Clinical SPF testing requires thousands of dollars and long approval times, which most small brands cannot afford. |
| Regulations limit claims | Handcrafted brands risk stricter drug regulations if they list SPF, leading many to stay in the cosmetic category. |
| Non-nano zinc is effective | High-zinc, non-nano formulas provide significant sun protection, even if they can’t officially claim an SPF number. |
| Brands focus on transparency | Small natural brands prioritize clear ingredient lists and consumer education instead of labeled SPF protection. |
The real cost of SPF testing for small brands
SPF testing is not a simple lab check. It requires clinical trials conducted on human volunteers, following strict protocols set by regulatory bodies. The process involves applying a measured amount of product to participants, exposing them to UV light, and measuring the time it takes for skin to redden compared to unprotected skin. That process takes weeks to months, and SPF clinical testing costs thousands before you even account for repeat testing, reformulation, or regulatory submissions.
For a large brand producing millions of units, that investment spreads thin. For a small-batch maker producing a few hundred jars at a time, it can be a budget-breaking commitment. Here is a rough comparison:
| Brand size | Estimated SPF testing cost | Units to recoup cost |
|---|---|---|
| Large brand | $10,000 to $50,000+ | Spread across millions of units |
| Small brand | $5,000 to $20,000+ | Must recoup across hundreds |
| Indie maker | Same cost, no discount | Often not financially viable |
Most small-batch makers do not pursue market validation and SPF costs until they have proven consistent demand. It is a practical business decision, not a reflection of product quality.
Pro Tip: If you are evaluating a small-brand sun product, look at the zinc oxide percentage listed in the ingredients rather than waiting for an SPF number. A 25 to 30 percent zinc oxide concentration is a meaningful indicator of broad-spectrum coverage.
Regulatory barriers: When sunscreen becomes a ‘drug’
Cost is only part of the picture. Regulations present another daunting challenge for small makers who want to list SPF.
In the United States, any product that claims to protect against sunburn or reduce UV exposure is legally classified as an over-the-counter drug by the FDA. That classification triggers a completely different set of manufacturing requirements. Specifically, brands must produce in facilities that meet Good Manufacturing Practice standards designed for pharmaceutical products. Handcrafted brands often cannot meet these drug GMP requirements because their facilities are built for cosmetics, not drugs.
Here is what that means in practice:
- SPF claims legally make a product an OTC drug, not a cosmetic
- Drug GMP facilities require specialized equipment, documentation, and audits
- Small kitchens and artisan studios simply do not qualify
- Brands that manufacture overseas can sometimes access certified facilities, but that often compromises sourcing values and transparency
The comparison between cosmetic and drug status matters a lot:
| Category | Regulatory burden | SPF claim allowed? |
|---|---|---|
| Cosmetic | Lower, manageable for small brands | No |
| OTC drug | High, requires GMP drug facility | Yes |
Many brands that care deeply about what counts as natural skincare choose to stay in the cosmetic category intentionally. It keeps them honest, keeps their sourcing clean, and keeps their formulas free from the compromises that come with scaling up to meet GMP and ingredient restrictions.
Why non-nano zinc and high-zinc balms skip SPF
Along with regulatory and cost pressures, ingredient choice shapes small brands’ decisions around SPF labeling.
Non-nano zinc oxide is the preferred UV-blocking ingredient in most natural and clean skincare formulas. It sits on top of the skin and physically deflects both UVA and UVB rays without being absorbed into the bloodstream. The EWG and FDA affirm zinc safety broadly, but raise concerns about nano-sized zinc particles, which are small enough to potentially penetrate skin. Non-nano zinc avoids that concern entirely.
Here is what you should know about zinc in natural sun products:
- Non-nano zinc oxide provides broad-spectrum UV coverage
- Higher zinc percentages generally mean stronger protection
- Zinc must be evenly dispersed to work correctly, which is why ingredients like lecithin matter
- Beeswax helps the formula stay on skin longer, improving durability during outdoor use
- Without clinical testing, a brand cannot legally claim an SPF number, even with 30 percent zinc
Our mineral sunscreen ingredients post goes deeper on how zinc compares to chemical filters. And if you want to know what to avoid, our guide on ingredients to avoid covers the most common offenders in conventional sunscreens.
Pro Tip: When you apply a high-zinc balm, use enough to fully coat the exposed area. A thin swipe is not enough. Reapply every 90 minutes during outdoor activity, just as you would with any sun product.
How indie brands adapt: Workarounds and transparency
Given these hurdles, how do small brands earn trust and inform their customers? Here is how the best ones do it:
- List the zinc oxide percentage clearly so consumers can evaluate protection potential on their own terms.
- Explain the formulation including supporting ingredients like lecithin for dispersion and beeswax for staying power.
- Educate on proper application because even the best formula fails if it is applied too thinly or not reapplied.
- Be transparent about limitations and encourage layering with other protective habits like hats and shade.
- Avoid vague claims that could mislead consumers into thinking a product offers more than it does.
Indie brands sometimes manufacture abroad to access certified facilities, but many choose to stay small and skip SPF claims rather than compromise their values. That choice deserves more credit than it typically gets.
“A zinc percentage you can see and verify is more honest than an SPF number generated in a lab you’ll never visit.”
Transparency around small batch manufacturing is one of the clearest signals that a brand is operating with integrity.
A closer look: Why SPF isn’t always the best measure for natural brands
Here is an opinion worth sitting with: the fixation on SPF numbers may actually work against informed consumer choices.
SPF measures one thing, redness from UVB rays, under controlled lab conditions. It says nothing about UVA protection, ingredient safety, or how a formula actually behaves on real skin throughout a real day. A product with 30 percent non-nano zinc oxide, lecithin for even coverage, and beeswax for durability may offer more practical protection than a chemical sunscreen with an SPF 50 label and a list of ingredients that raise legitimate health questions.
We believe consumer education and ingredient transparency are more valuable than a number on a label. You deserve to understand safe natural skincare tips and make choices based on what is actually in the formula, not just what the marketing says.

Frequently asked questions
Why can’t small brands afford SPF testing?
SPF testing costs thousands in clinical trials and specialized labs, making it financially out of reach for most indie brands producing small batch volumes.
Is high-zinc balm as protective as labeled SPF products?
Non-nano zinc offers effective broad-spectrum UV protection, but without clinical testing, an exact SPF number cannot legally be claimed or printed on the label.
What keeps a balm a ‘cosmetic’ instead of an ‘OTC drug’?
A skincare product stays in the cosmetic category by avoiding SPF claims and drug-related promises, which sidesteps FDA drug GMP requirements that small-batch facilities cannot meet.
Can small brands label SPF if they manufacture overseas?
Some brands manufacture abroad to access certified drug GMP facilities, but this approach often raises questions about sourcing values, cost, and ingredient transparency.
