Custom Cosmetic Formulation & Private Label Product Development

R&D Capabilities

Our Research & Development capabilities are at the core of our custom formulation services

We maintain a state-of-the-art formulation lab equipped with modern mixers, stability testing chambers, and analytical instruments to ensure each product’s quality and longevity. Our R&D team consists of experienced cosmetic chemists and formulation engineers with deep expertise across skincare, haircare, and personal care categories. Led by senior chemists with 20+ years of experience, the team stays ahead of industry trends through continuous innovation and education. We can develop a wide range of formulas – from organic and natural products to clinical-grade cosmeceuticals with active ingredients, as well as on-trend formulations featuring the latest innovations (e.g. probiotics, CBD, K-beauty inspired ingredients).

One of our standout capabilities is the ability to reverse-engineer and replicate market-leading products upon request. Using competitive product analysis and ingredient benchmarking, our chemists can create “dupe” formulas with up to 99% similarity in performance and texture to popular products. This means if you have a reference product you admire, we can rapidly develop a closely matching formula while avoiding any infringing issues. We also excel at bespoke formulation, crafting original recipes from scratch that embody your brand’s concept and desired benefits. Every formulation undergoes rigorous stability and microbe testing in-house to ensure it remains effective and safe throughout its shelf life.

His involvement ensures that even small and medium-sized brands receive world-class formulation quality previously reserved for major global players.

Dr. Jiang – Pioneer in Collagen Skincare Innovation

Creator Proprietary Collagen Skincare Line Recognized by Leading Global Brands

Another cornerstone formulation strength is Dr. Jiang, a distinguished cosmetic chemist and pioneer in collagen-based skincare. With a PhD in cosmetic science and over 15 years of experience in biomolecular research, Dr. Jiang has developed a proprietary collagen skincare line that has earned recognition from international luxury beauty brands across Europe and the U.S.

Her innovative approach focuses on hydrolyzed marine collagen, encapsulation technology, and anti-aging peptide complexes, allowing custom formulas to deliver visibly firmer, more radiant skin. Thanks to her expertise, Zerun is able to offer high-performance collagen products that meet the standards of clinical skincare, while still allowing private-label customization for emerging brands.

Whether you’re developing a premium face cream, serum, or firming mask, Dr. Jiang’s lab brings science, innovation, and global trend insights into every formulation.

At Zerun Cosmetic, offer end-to-end custom cosmetic formulation and private label product development services to turn your product concepts into reality. As a bespoke skincare manufacturer, our team of skilled cosmetic chemists can develop skincare, haircare, and personal care formulas tailored to your brand’s vision. Whether you have an original product idea or want to adapt a trending market product, we provide flexible OEM/ODM solutions from formulation through production. Our expertise ensures that each formula is unique to your brand, giving you a competitive edge with proprietary products. We pride ourselves on being a one-stop private label product development partner – from initial concept through R&D, testing, and final manufacturing – delivering high-quality, market-ready cosmetics that align with your target audience and brand ethos.

Co-Development Process

Our co-development process is collaborative and streamlined, designed to bring your product from concept to reality efficiently. We typically follow four key steps:

1. Concept & Consultation

We begin with a detailed discussion of your product concept, target market, and requirements. Our team can advise on ideal ingredients, textures, and claim ideas based on your vision. (Example: If you want a moisturizing anti-aging serum for sensitive skin, we’ll propose suitable actives and formulation strategies.)

2. Sample Formulation

Next, our chemists develop an initial prototype formula using your concept as a blueprint. We blend and adjust ingredients to create a sample, which is sent to you for evaluation. With a fast turnaround, samples are typically ready in 7–10 days so you can begin testing the product quickly.

3. Sample Revise

After you test the sample, we gather feedback on scent, texture, performance, and more. Our R&D team flexibly adjusts the formula—enhancing richness, modifying fragrance, or adding preferred ingredients. We support multiple revisions to ensure the formula meets your expectations. The process is fast, transparent, and keeps you involved.

4. Final Formula Approval

Once you’re fully satisfied with the sample, we finalize the formula and prepare it for production. A final approved sample is created for your sign-off, and the formula is documented for manufacturing. With your approval, the product enters production and filling in our facilities. The result is a custom, launch-ready formula developed in weeks without compromising quality.

Throughout this co-development process, we emphasize speed without sacrificing quality. Our agile approach and in-house lab capabilities allow for rapid prototyping and adjustments. We also offer sample provision at each stage – you’ll physically experience the product before any commitment to full production. This reduces risk and ensures you love the product formula before scaling up. Our goal is to make product development fast, flexible, and worry-free for you.

What Benefits to our OEM ODM Client

Partnering with us for custom formulation offers significant benefits for your brand: Your success is our priority, and we strive to be not just a manufacturer but a strategic partner in your brand’s growth.

Unique, Tailored Products

You receive formulations crafted specifically for your brand story and target customers. This exclusivity helps differentiate your brand in the market with one-of-a-kind skincare or personal care products, rather than generic stock formulas.

Reduced R&D Investment

You gain an expert R&D department without the overhead. Our in-house chemists handle complex formulation work, saving you the cost of setting up a lab, sourcing ingredients, and hiring scientists—lowering development cost while maintaining high quality.

Faster Time-to-Market

With our efficient process and ready infrastructure, you launch products faster. We compress timelines—delivering samples in days and final formulas in weeks—so you capitalize on trends and start generating sales sooner.

Quality & Efficacy

Every formula is professionally developed and tested to ensure it meets high standards of efficacy and safety. This leads to effective products that win customer loyalty. You can be confident in claims like “clinically proven” or “dermatologist tested” because of the rigorous development behind each item.

Regulatory Peace of Mind

Our support with compliance and documentation means you avoid the pitfalls of regulatory issues. Enter any international market knowing your product’s formula and labeling are compliant. This reduces risk and streamlines the process of selling in multiple regions (North America, EU, Asia, etc.).

Access to Innovation

You tap into the latest cosmetic innovations through us. We research emerging ingredients, textures, and trends. As our client, you access this innovation pipeline – with new product ideas or upgrades that keep your line fresh and competitive.

Compliance & Safety

We understand that regulatory compliance and product safety are non-negotiable in the cosmetics industry. All our custom formulations are developed to meet the regulations of your target markets, including the EU, USA, Australia, Japan, Korea, and other major regions. Our regulatory team stays up-to-date with international cosmetic laws – from the EU’s Cosmetic Regulation (EC No. 1223/2009) to FDA guidelines in the U.S. – ensuring every ingredient and finished formula is compliant. We also design products to be cruelty-free (no animal testing) and can accommodate vegan, halal, or other specific standards on request.

Every formula is assessed for safety. We provide comprehensive documentation and support for product registration and safety review, including Material Safety Data Sheets (MSDS), full ingredient lists, and assistance with any required safety assessments. For example, we can assist with preparing the Cosmetic Product Safety Report (CPSR) for EU markets and guide you through product notification (CPNP). We adhere to Good Manufacturing Practice (GMP, ISO 22716) standards in our production, which means traceability and quality control are built into our process. Stability testing is performed to guarantee that the product maintains its integrity under various conditions, and we conduct microbial and allergen testing as needed to ensure the product’s safety for consumers.

Additionally, we support certification needs: if your brand requires organic certification (e.g., COSMOS/Ecocert), dermatologically tested claims, or specific market approvals, our team will help navigate those processes. We also provide compliance label support – making sure that your product’s packaging and labeling meet the legal requirements (ingredient listings, warnings, etc.) in each region. With our focus on compliance and safety, you can confidently launch your private label products worldwide, knowing they meet all regulatory standards and won’t run into compliance issues.
