Custom Skincare Formulation: Write the Brief Before Requesting Samples
A useful custom skincare formulation brief tells a manufacturer what the finished product must do, how it should feel, where it will be sold and how it will be packaged. An ingredient wish list is only part of that brief. Before paying for development, establish whether you need a new formula, an adjustment to an existing one or a private label product with different packaging.
This guide turns themes from the 2023 Guangzhou Cosmetics Industry White Paper into practical questions for international buyers. Its discussion of skincare segmentation, formulation research and manufacturing development provides industry context. The specification sheets and purchasing checks below are YIFA PLAZA’s editorial recommendations, not a supplier approval or a test result from the report.
Define the difference your buyer should notice
“An innovative serum” leaves a development team guessing. Describe the intended user, product format and use experience before choosing an ingredient story.
For a serum, that might mean a lightweight product used before a moisturiser, a particular absorption feel, a fragrance preference and a dispenser that delivers a controllable amount. These are example brief fields, not a proposed formula or performance promise.
A reference product can help explain texture, finish or dispensing. State which characteristics matter and which should differ. Ask the manufacturer to develop against the written brief rather than to copy another brand’s formula, identity or packaging.
The white paper describes increasing differentiation within skincare and attention to ingredients and product effects in its 2023 discussion, particularly on printed pages 67–70. Use that observation to sharpen a product brief. It does not establish present-day demand for your target country or prove that a particular ingredient will sell.
Match the brief to the product format
The serum example above focuses on texture and dispensing. Other skincare formats need different information in the same development brief.
Creams and lotions: make the texture reference specific
Texture descriptions such as rich and lightweight can be interpreted differently. Describe spread, absorption feel and the finish after application. Then ask the supplier to explain the proposed jar, tube or pump choice for that texture. Compare samples using the same agreed observations before selecting packaging by appearance.
Cleansers: begin with the way the product will be used
Tell the supplier whether you are considering a gel, cream, oil or foam format, and describe the intended cleansing routine. Ask how samples should be evaluated for dispensing, rinsing and after-use feel. A high-foam appearance or an ingredient name alone is not a complete description of the product you want.
Sheet masks: specify the sheet as well as the liquid
Request the sheet material, dimensions, cut pattern, liquid fill quantity and individual sachet specification together. Compare fit, unfolding and handling using the proposed combination. Ask the supplier to identify the checks used for fill consistency and sachet sealing; a liquid sample on its own leaves those purchasing decisions unresolved.
For a private label skin care line, ask for quantities and component requirements for each product separately. Do not assume that a cleanser, serum and cream can share one MOQ simply because they use the same branding. The selected manufacturer must confirm the formula, packaging, documentation and production scope for each item.
Decide what actually needs to change
The labels OEM, ODM and private label do not tell you the complete development scope. Request a written description of the work included in the quotation.
| Your starting point | What to ask the supplier | What to confirm before proceeding |
|---|---|---|
| An existing formula already fits the brief | Can we evaluate the current formula in our intended pack? | Formula identification, available documentation, permitted branding changes and the tests required for the chosen pack. |
| The base formula is close, but texture, fragrance or another feature must change | Which changes are feasible, and what development work will they trigger? | A new revision identifier, responsibility for evaluation, sample-round costs and which previous results remain applicable. |
| The product needs a substantially different formula | Who will develop it, and what are the proposed development stages? | Deliverables, sample iterations, evaluation responsibilities, commercial terms and access to the agreed documentation. |
If the difference you need is limited to artwork and presentation, custom formula development may add work without solving a buyer problem. If the product’s intended characteristics cannot be achieved with an available formula, identify that gap explicitly before discussing costs.
Compare the broader OEM, ODM and private label sourcing routes. For available product categories and supplier matching, use the skincare sourcing page.
Send a brief that produces comparable quotations
Give every shortlisted supplier the same document. Separate a firm requirement from a preference, and mark anything still undecided.
| Brief field | Information to provide |
|---|---|
| Product and intended user | Product type, intended use and the customer group you plan to serve. |
| Sales destination | Target countries and sales channels; identify who will coordinate the relevant market review. |
| Sensory reference | Texture, spread, absorption feel, finish and fragrance preference. Describe any reference sample precisely. |
| Ingredient requirements | Requested ingredients, restrictions and the reason for each requirement. Ask the supplier to assess feasibility. |
| Proposed claims | The exact draft wording, with a separate record of the evidence needed to support it. |
| Packaging | Fill size, container, dispensing method, decoration and any components you have already selected. |
| Commercial assumptions | Estimated first order, target cost basis, preferred launch window and expected repeat demand. |
| Development deliverables | Sample identification, revision records, evaluation plan, documentation and approval responsibilities. |
Include the cost basis when stating a target price: bulk formula, filled product, decorated primary pack or a finished retail unit are different requests. Ask for development, samples, testing, components and production to be itemised where applicable. MOQ and lead time must be confirmed for the actual formula and pack.
Keep ingredient evidence separate from product evidence
A document about an ingredient does not, by itself, demonstrate the performance of the finished product you intend to sell. Ask what was evaluated, which sample or formula revision was used, what the evaluation covered and who issued the result.
The white paper’s quality-comparison discussion on printed pages 90–91 considers raw materials, formulation, processes and finished products. Its findings concern the work described in that report. They do not verify every Guangzhou supplier or replace evidence for your order.
For each document received, record:
- The product, formula revision or sample identifier to which it refers.
- The purpose, method and scope of the evaluation.
- The date, issuing organisation and relevant limitations.
- Whether the material provided supports the specific wording or decision under review.
If the supplier changes the formula, ask which results must be reviewed again. Keep this question open until the responsible technical reviewer has assessed the change. For company identity and broader documentation checks, use the cosmetic manufacturer verification guide.
Choose the pack before treating the sample as final
An approved texture in a sample pot does not settle the dispensing and packaging decisions for the retail product. Tell the developer which container and dispensing system you intend to use, and agree on the checks needed for that combination.
Ask the supplier to identify the pack used for evaluation, component specifications, fill quantity, observations and acceptance criteria. Record changes to either formula or packaging. A new pump, closure or material should not disappear into an informal message thread.
Our airless pump and lotion bottle comparison covers packaging choices and the evidence to request. Use it for the pack decision; keep the formula brief focused on the product being developed.
Set responsibilities before the first revision
The white paper discusses formulation research, OEM/ODM development and the relationship between manufacturers and brands on printed pages 115–117. Its examples show why manufacturing access and development capability need separate consideration.
For your own project, identify who owns each next action: drafting the brief, proposing the formula, arranging evaluation, choosing components, checking documentation and approving changes. Request written commercial terms covering development fees, included revision rounds, confidentiality and any requested exclusivity. The availability and scope of those terms must be agreed with the supplier; they should not be assumed from a service label.
Maintain a short revision record. For each sample, note its code, date, requested change, observations and the decision: reject, revise or advance to the next evaluation. Do not reuse one “approved sample” label for several different versions.
What to send YIFA PLAZA
Send the product type, intended market, estimated quantity, formula or sensory reference, packaging direction and the decisions you still need help making. Include any ingredient restrictions and proposed claims as items for review.
YIFA PLAZA can use that brief to discuss supplier-matching options in Guangzhou. The selected supplier must confirm development scope, feasibility, documentation, MOQ and lead time for the project.
Send your skincare project requirements.
