Selling homemade skincare might sound simple; you make a cream in your kitchen, design a cute label, and post it on Instagram.
But in the eyes of the law, your product is still a cosmetic and cosmetics are regulated. Whether you’re just starting a small skincare brand or want to sell handmade face creams at your local market, you need to follow certain safety and legal steps. Skipping them could get your product banned, recalled, or worse: could harm someone.
This guide breaks down five essential things you must do before legally and safely selling water-based skincare products.

1. Know the Laws Before You Sell
Who Regulates Cosmetics in Your Country?
Every country has its own authority that governs cosmetics.
In the United States, regulation is overseen by the Food and Drug Administration (FDA). The regulatory landscape was significantly expanded by the new Modernization of Cosmetics Regulation Act (MoCRA), representing the first major federal update in over 80 years.
In the EU, it’s the European Commission under Regulation (EC) No. 1223/2009.
Australia, New Zealand, China, and Japan all have their own rules too.
Before selling, you must find out who regulates skincare in your region and what they require from small-scale makers.
Do You Need a License to Sell Homemade Skincare?
In most countries, you don’t need a specific cosmetic manufacturing license to sell skincare, but you are legally responsible for product safety and compliance. That means your products must meet all cosmetic regulations, even if you make them at home or in small batches.
Some countries (like Japan, India, Brazil, and parts of the EU such as Spain or Lithuania) don’t allow home-based cosmetic manufacturing at all. In these regions, production must happen in a licensed or GMP-certified facility under the supervision of a qualified professional. Others, like the U.S., UK, Canada, Australia, and most EU countries, do allow small-scale or home production; as long as you follow Good Manufacturing Practices (GMP) and maintain hygiene standards that prevent contamination.
Keep in mind that “working from home” doesn’t mean using your family kitchen. Your workspace must be clean, organized, and separate from food areas, pets, or any source of cross-contamination. You’ll need to sanitize all tools, surfaces, and containers before and after each production run.
Even if your country doesn’t require a formal manufacturing license, you may still need a general business license for tax and registration purposes. Always check your local regulations; some U.S. states (like Florida) or Asian markets have extra rules for cosmetic makers.
Ultimately, it’s not about having a license; it’s about proving that your product is made safely, under proper conditions, and in compliance with cosmetic law. Whether you produce 10 jars a week or 10,000, the same principles apply.
Countries Where Homemade Cosmetics Are Restricted
Some regions have strict regulations that make selling home-produced cosmetics difficult or even impossible. For instance, in the European Union, all cosmetics must have a Cosmetic Product Safety Report (CPSR) and a Responsible Person registered under Regulation (EC) No. 1223/2009. These requirements mean that home-made creams can’t be placed on the market unless a professional safety assessor has reviewed the formula and verified stability and preservative test results.
Countries such as Japan, India, and Brazil also restrict or prohibit home manufacturing entirely. In these markets, cosmetics must be made in licensed facilities that comply with Good Manufacturing Practice (GMP) and are supervised by qualified technical staff.
Even in regions that allow small-batch or home production (like the U.S., U.K., Australia, or Canada), selling untested or unverified products is still illegal. You must be able to prove product safety, hygiene compliance, and accurate labeling before going to market.
The safest approach (regardless of where you live) is to consult your local cosmetic authority or a qualified regulatory professional before selling. Rules vary widely, but one thing is universal: if your product is unsafe, unstable, or untested, it’s not legally fit for sale anywhere.
2. Water-Based Products Require Safety Testing
What Is a Preservative Challenge Test?
Any skincare product that contains water (like a lotion, cream, or serum) can grow bacteria, mold, or yeast if it’s not properly preserved. A preservative challenge test checks whether your chosen preservative system can actually protect the product over time. In this test, the formula is intentionally contaminated with microbes and observed to see if it can kill them within a set period. This is a legal requirement in many countries and essential for customer safety.
Why Stability Testing Isn’t Optional
Even if your product is safe when fresh, how do you know it will stay that way after three or six months? Stability testing exposes your formula to heat, cold, light, and time to see if it separates, changes color, grows mold, or loses effectiveness.
It helps you set an accurate shelf life and avoid surprises like leaky packaging or a watery texture later on. Without stability data, regulators may see your product as risky and customers might lose trust.
Do You Need Lab Reports?
In most countries, you’re not legally required to send your product to a professional lab before selling it, but you do need solid evidence that it’s safe and stable. This evidence can come from your own in-house tests, but third-party lab reports carry far more credibility and are often expected during audits or safety reviews.
Every cosmetic (whether water-based or anhydrous) should undergo stability testing to ensure it remains consistent in texture, scent, and performance over time. However, once water is introduced into the formula, preservative efficacy (challenge) testing becomes a critical additional requirement. This test verifies that your preservative system can control microbial growth when the product is intentionally inoculated with bacteria and fungi.
In many regions, particularly within the EU, UK, and China, accredited laboratory testing is the accepted standard for these evaluations. Certified labs use validated protocols (such as ISO 11930 or USP <51>) to provide official documentation of microbial safety and shelf stability. While not every small brand is legally bound to use a lab, doing so is the safest and most professional route; it protects your customers, your reputation, and your brand’s compliance record.
3. You’re Legally Responsible for Product Safety
What Does “Adulterated Product” Mean?
Even if your cream looks smooth and smells amazing, it can still be considered adulterated under cosmetic law.
In simple terms, an adulterated cosmetic is one that has become unsafe for use; either because it contains a harmful or impure substance, or because it was produced or stored in unsanitary conditions.
Under U.S. law (FDA), a cosmetic is considered adulterated if:
- it contains any poisonous or deleterious substance that could make it harmful when used as intended,
- it was prepared, packed, or held under insanitary conditions that may cause contamination,
- or if its container itself could make the product unsafe due to toxic materials.
This doesn’t automatically mean every home-made product is illegal; but if you make skincare in a space that isn’t sanitary or you skip microbial testing, your product could easily fall under this definition. Once a product is classified as adulterated, it’s unlawful to sell or distribute it.
The same core idea applies globally: regulators in the EU, UK, and other regions expect every product on the market to be safe for human use under normal conditions. That means it’s your responsibility as the maker to ensure that every jar leaving your hands is clean, stable, and free from contamination.
GMP for Small-Batch Makers (Even Home Labs!)
Good Manufacturing Practice (GMP) isn’t just for factories. It’s the basic hygiene and consistency standard you must follow, even when you’re making small batches. That means working in a clean, organized environment, sanitizing your tools, wearing gloves, and recording every batch you make. You should also log your ingredient suppliers, batch numbers, and lot codes. Keeping a clean, traceable system not only helps in case of audits; it also protects your reputation if a customer ever reports an issue.
How to Document Your Manufacturing Process
Every cosmetic maker should have a system for documenting production. Note the date, batch size, formula version, and any process notes (temperatures, mixing times, etc.). Keep copies of ingredient Safety Data Sheets (SDS) and Certificates of Analysis (COA) from suppliers. These records form the foundation of your Product Information File (PIF) in the EU or your safety substantiation file in the U.S. If you ever face a safety complaint, these files will prove that your product was made responsibly and in compliance with cosmetic laws.
4. Labels Matter More Than You Think
Why Labeling Rules Exist
Your label isn’t just design; it’s part of legal compliance. Cosmetic laws in every major market require labels to inform and protect consumers. A proper label helps customers use your product safely, trace it back to you if needed, and proves to regulators that you’re transparent about what’s inside. Incorrect or misleading labels are one of the most common reasons small brands face recalls or fines.
What Must Be on a Cosmetic Label
While details vary by region, the basics are nearly universal. Every cosmetic label should include:
- Product name and intended use (e.g., “Face Cream” or “Moisturizing Lotion”)
- Ingredients list in descending order by weight, using INCI (International Nomenclature of Cosmetic Ingredients) names
- Net content (e.g., 50 mL / 1.7 oz)
- Manufacturer or distributor name and address
- Batch number or lot code for traceability
- Warnings or directions for safe use, if relevant (for example, “Avoid contact with eyes”)
- Expiration date or Period After Opening (PAO) symbol, especially for water-based creams
Each region may have its own twist. For example, EU labels must include the country of origin for imported products, while the U.S. focuses on ingredient transparency and net quantity on the principal display panel. New Zealand and Australia also require English-language labeling and ingredient lists.
Common Labeling Mistakes to Avoid
Even small errors can make your product “misbranded” in the eyes of regulators. Avoid these common traps:
- Using non-INCI names like “Coconut Oil” instead of “Cocos Nucifera (Coconut) Oil”
- Omitting your business name or address, making the product untraceable
- Making medical or drug-like claims (e.g., “heals eczema” or “treats acne”): these instantly reclassify your cream as a drug
- Forgetting batch numbers or expiry details, which are critical for recalls or shelf-life tracking
- Using ambiguous or misleading terms like “chemical-free,” which authorities may flag as deceptive
Can You Use Terms Like “Natural” or “Anti-Aging”?
These claims are tricky. While words like “natural” aren’t strictly defined in most countries, you must be able to prove that your product matches what you claim. “Anti-aging,” “brightening,” or “healing” are even riskier; they imply a physiological effect, pushing your product into the “drug” category in some regions. Keep claims cosmetic: say “hydrates,” “softens,” or “improves skin feel” instead. Always be ready to back up your claims with ingredient data or performance testing if questioned.
5. Keep Safety Files and Be Ready for Inspection
What’s a Product Information File (PIF)?
If you plan to sell in the EU or UK, you’ll need to prepare a Product Information File for each cosmetic you sell. This document contains all the technical and safety information about your product; including ingredient lists, manufacturing details, test results, and the safety assessment report. Even if your country doesn’t require a formal PIF, keeping a similar safety file is smart. It proves you’ve done your due diligence and can protect you if your product is ever questioned by regulators or customers.
Do You Need to Report Adverse Reactions?
Yes, in most regions, you have a legal and ethical duty to record and report any adverse reactions linked to your products. In the U.S., under the Modernization of Cosmetics Regulation Act (MoCRA), brands must report any serious adverse events to the FDA within 15 business days. In the EU, this responsibility lies with the Responsible Person, who must notify authorities immediately. Keeping accurate customer feedback logs and batch records ensures you can trace any problem back to its source.
How Long Should You Keep Your Test Results and Safety Records?
Store all your safety documents; stability reports, challenge test results, raw material data sheets, and manufacturing logs, for at least 10 years after your last batch was sold (this is the EU standard). These records should be easily accessible to regulators if they ever audit your brand. It’s also good practice to back up digital copies securely in cloud storage.
Remember: your paperwork is part of your product’s credibility. No documentation means no proof that your product is safe.
