Starting a sunscreen business is one of the most rewarding and most demanding ways to enter beauty. Demand is year-round in tropical markets, customers repurchase often, and a good formula earns loyalty that a serum rarely does. But sunscreen is also the one product where the rules are stricter, the testing is non-negotiable and a vague plan gets expensive fast. This guide lays out the decisions a first-time founder has to make, in the order they come, so you can budget honestly and avoid the mistakes that stall most sun care launches.
Why sunscreen is a harder first product than it looks
Founders often pick sunscreen because they use it every day and see the demand. That instinct is right about the market and wrong about the difficulty. Three things make sun care different from a moisturiser or a body wash.
- **It is regulated as more than a cosmetic in many markets**: in some countries sunscreen is treated as an over-the-counter drug or a special-category cosmetic, which means specific approved filters, mandatory efficacy testing and tighter labelling. The rules differ between ASEAN, the EU, the Middle East, Australia and the United States, so your target market decides your formula, not the other way round.
- **Claims must be proven**: an SPF number and a water-resistance claim are not marketing lines; they are test results. If the label says SPF 50, there is a lab report behind it, and the authorities can ask to see it.
- **Formulation is technically demanding**: UV filters are hard to stabilise, mineral filters can leave a white cast, and texture preferences in tropical markets lean toward very light, fast-absorbing products that are difficult to make without sacrificing protection.
None of this means you should avoid sunscreen. It means you should treat it as a project with a longer runway and a bigger compliance line than a simple cosmetic. Founders who go in expecting a quick private label flip usually stop halfway; founders who plan for testing and registration from day one tend to launch a product they can defend. If your budget or timeline cannot absorb that, a sunscreen-adjacent product such as an after-sun gel or a tinted moisturiser without SPF claims can be a sensible first step while you learn the category.
Choose your business model before you choose a formula
There are three practical ways to start your own brand in sun care, and the right one depends on how much control you want versus how much time and money you can commit.
- **Private label on an existing formula**: the manufacturer already has a tested sunscreen base with efficacy data. You choose packaging, branding and maybe a scent or tint. Fastest route, lowest development risk, least differentiation. Ideal if your advantage is brand building and distribution rather than formulation.
- **Custom formulation**: you brief a lab on filters, texture, finish and actives, and they develop a formula for you. It takes several sample rounds and the full set of tests, which you usually pay for, but the product is yours and can be positioned on something competitors cannot copy.
- **Hybrid**: start with an existing base for your launch SKU, learn from customer feedback and fund a custom formula for the second generation. Many successful small brands quietly do this.
Whether you work directly with a factory or through a full-service partner such as 5FINE that manages formulation, packaging, documentation and production across its partner factories, the model decision comes first because it sets your budget shape. The standard MOQ for contract manufacturing is 1,000 units per SKU, so a brand with two textures and two sizes is committing to four SKUs and four times that quantity. Starting with one hero SKU on a proven base, then expanding, is the lowest-risk version of this business.
The product decisions: filters, protection claims, texture, audience
Once the model is set, the product brief needs five concrete decisions. Make them on paper before any sample is requested.
- **Filter system**: chemical (organic) filters give lighter textures and no white cast; mineral filters such as zinc oxide suit sensitive-skin positioning and "clean" marketing but are harder to make elegant; hybrids balance both. Which filters you can use depends on the approved list in your target market, so confirm it with your manufacturer early.
- **Protection claims**: SPF level and, where relevant, a UVA rating such as PA or a broad-spectrum statement. Higher claims need the same testing but often cost more in filters and can affect texture. Choose the claim your customer actually asks for, not the biggest number.
- **Texture and finish**: gel, fluid, lotion, cream, stick or spray; matte or dewy; fragrance-free or lightly scented. In humid markets, lightweight fluids with a natural finish tend to win repeat purchases.
- **Target customer**: daily city wear, outdoor sports, children, acne-prone skin, mature skin. One audience per SKU keeps claims and texture coherent.
- **Extras and positioning**: tint, antioxidants, soothing botanicals, reef-conscious messaging. Each addition must be supported by the formula and must not contradict a regulatory rule.
Write these into a one-page brief with two or three reference products you admire. A good manufacturer will push back on anything that conflicts, for example a very high SPF in an ultra-light mineral-only fluid, and that pushback is worth more than a yes.
Testing and compliance you cannot skip
This is the section founders most want to shorten, and it is the one that protects the business. Requirements vary by market, so verify the current rules with the regulator or a compliance consultant in each country you sell in, but the usual components are these.
- **SPF efficacy testing**: typically an in-vivo test on human volunteers under a recognised method, sometimes preceded by in-vitro screening to choose the final formula. Required for any SPF claim.
- **UVA and broad-spectrum testing**: where you plan to claim PA ratings or broad-spectrum protection.
- **Water or sweat resistance testing**: only if you make the claim; do not claim it without the data.
- **Stability testing**: accelerated and real-time, in the final packaging, to confirm the product and its protection hold up over shelf life.
- **Safety and compatibility**: microbiological challenge testing, and often a patch or irritation test for sensitive-skin positioning.
- **Product registration or notification**: in Thailand, cosmetics are notified with the Thai FDA; your destination market will have its own process, which may be a cosmetic notification or a stricter approval for sun care. Check with the authority in each market before printing labels.
- **Labelling**: mandatory warnings, directions, ingredient list and claim wording follow market-specific rules.
Ask the manufacturer, up front, which tests are included in their quotation, which are extra, which laboratory performs them and who owns the reports. Owning the reports matters if you ever change manufacturer. Budget time as well as money: testing runs in sequence, and a formula change after SPF testing means testing again.
Budget lines and the realistic first production run
A sunscreen budget has more lines than most founders expect. Figures depend on the formula, packaging and market, so instead of numbers, here is the full list of lines so nothing surprises you later.
- **Development**: sample rounds and, for custom work, a development fee.
- **Testing**: SPF, UVA, water resistance, stability, safety, as applicable.
- **Regulatory**: notification or registration fees, documentation, consultant time, label review.
- **Packaging**: primary pack such as a tube or airless bottle, secondary carton, printing plates, minimum order quantities from the packaging supplier, which are separate from the product MOQ.
- **Production**: the first run at the standard 1,000 units per SKU, plus any surcharges for small runs or special filling.
- **Brand and content**: logo, design, photography, website, product copy and the legal review of claims.
- **Logistics and duties**: freight, insurance, customs and local delivery.
- **Working capital**: you pay most of the above before the first sale, and sunscreen stock has a shelf life, so plan to sell through within it.
A realistic first run is one SKU, one size, in packaging that the manufacturer has already used with that formula, because packaging compatibility problems are a common cause of failed stability tests. Keep a reserve for a second sample round and a re-test; founders who budget exactly to the plan run out at the moment a small change is needed. Pricing from the manufacturer will depend on product and quantity, and the team will advise once the specification is fixed, so treat early numbers as directional.
Brand building and the launch plan
The formula earns trust; the brand earns the first purchase. Sunscreen is a crowded category, so your positioning has to be sharp enough to explain in one sentence: who it is for, what it feels like and why they should believe you.
- **Positioning**: pick one wedge. Examples: a fluid for oily, acne-prone skin in humid cities; a mineral option for sensitive skin and children; a tinted daily SPF for people who skip makeup. Trying to be for everyone makes you invisible.
- **Claims discipline**: every claim on the pack and in your content must trace to a test or an ingredient fact. Build a claims sheet before writing a single caption, and have it reviewed against your market's rules. Avoid medical language and absolute promises.
- **Content that educates**: sunscreen customers respond to demonstrations: texture on skin, white-cast comparisons, reapplication routines, how to layer under makeup. Honest education outperforms hype.
- **Channel**: start where your audience already buys sunscreen. A single marketplace or your own site plus a few trusted resellers is easier to manage than six channels at once.
- **Launch sequence**: samples to a small group for real feedback, then a soft launch to an email or chat list, then the public push. Keep some stock aside for creators and press rather than selling out on day one.
- **Repeat purchase**: sunscreen is a replenishment product. A reminder email, a refill or bundle offer and a loyalty mechanic are worth more than a larger launch budget.
Treat the first year as learning what your customer values. Brand building is cumulative; the second SKU, informed by real reviews and sell-through data, is where most sun care brands actually find their identity.

FAQ
Frequently asked questions
Can I start a sunscreen business with a private label formula?
Yes, and for most first-time founders it is the sensible route. A private label sunscreen uses a base formula the manufacturer has already tested, so development risk is low and launch is faster. You still need the efficacy and stability data to apply to your product and packaging, and your own registration in the market where you sell, so confirm what the manufacturer provides and what you must arrange.
What is the minimum order for a sunscreen production run?
The standard MOQ in contract manufacturing is 1,000 units per SKU. Each texture, size or tint counts as its own SKU, so a line with several variants multiplies that quantity. Packaging suppliers set their own minimums, which may be higher than the product MOQ, so check both before you finalise the range.
Do I really need SPF testing if the manufacturer already tested the base formula?
Ask the manufacturer and the regulator in your market. Existing test reports may cover your product if the formula and packaging are unchanged and the reports can be assigned to your brand, but any change in filters, actives or packaging can require new testing. Confirm who owns the reports and whether they can be used for your registration before relying on them.
Which markets are easiest for a new sunscreen brand?
There is no universally easy market, but markets where sunscreen is regulated as a cosmetic with a notification process are generally simpler than those that treat it as a drug requiring pre-approval. Many Thailand-made brands start in ASEAN markets for that reason. Always check the current rules with the authority in each country, because requirements change and vary by filter and claim.
