Existing Formula / Private Label
Start with an existing formula and evaluate whether its texture, appearance, fragrance, and performance fit your brand.

Skincare Sampling and Formula Approval
Rixin helps skincare brands review samples, give clear feedback, and approve the formula direction before production planning.
Formula approval confirms the agreed formula direction. Packaging, testing, artwork, target-market requirements, and production readiness are reviewed separately.
Share your product goals, current formula status, target market, packaging direction, and the feedback you need from the next sample.
Before Sampling: Confirm the Brief and Inputs
Start sampling once you know the product you want to create and the type of formula development it needs: an existing formula, an adjustment to an existing formula, or custom development.
You do not need every detail before you contact Rixin. Share the information you have, including:
- Product type, target customer, and intended use
- Target market
- Desired texture, finish, and fragrance preference
- Ingredients to include or avoid
- A reference product, if available
- Packaging direction and expected quantity
- Current formula status and decisions still open
Choose the Formula Development Route
The sampling process depends on whether you are starting with an existing formula, requesting adjustments, or developing a custom formula.
Formula Adjustment
Make limited changes to an existing formula, such as texture, fragrance, appearance, skin feel, or selected ingredients. Larger changes may need custom development.
Custom Formulation
Develop a new formula or make changes that go beyond the private-label route.
Explore Custom Formulation and OEM or review Formula Development .
Evaluate the Sample
Evaluate the sensory direction—how the product feels, spreads, and smells—against the goals agreed in the product brief.
- Appearance and color
- Fragrance
- Texture and thickness
- How it spreads and applies
- Absorption and finish
- Tack, slip, residue, or pilling, where relevant
- How it dispenses
- How it fits into the intended routine
- Overall fit with the product goals
Use consistent evaluation conditions where practical and compare the sample with the agreed product goals.
Give Clear Feedback and Manage Revisions
Send one clear feedback response for each sample. Identify the sample version, what meets the brief, and the requested change in observable language.
- What you accept
- What should change
- How important each requested change is
- Whether the change concerns texture, fragrance, appearance, application, finish, or another agreed goal
- Photos or reference comparisons, where useful
- What should remain unchanged
Current observation → Desired direction → Priority → Reason or reference
A normal revision addresses agreed feedback within the original product goal. A scope change means the new request changes the original product goal, formula route, ingredient direction, packaging requirement, or another major project condition.
We’ll confirm whether the request is a normal revision or changes the project scope. Major changes may affect development work, cost, and timing; revision count and commercial terms depend on the project.
What Formula Approval Confirms
Formula approval confirms that the agreed formula direction has been accepted for the current project stage.
Formula approval confirms:
- The agreed formula direction
- The agreed texture, fragrance, appearance, application, and finish
- The accepted sample reference
- The agreed revision outcome for the current stage
Still reviewed separately:
- Whether the formula works with the final package and dispensing system
- Required testing and documentation
- Artwork, order details, target-market requirements, and production readiness
The approved sample is the reference for the next agreed steps.
Packaging, Testing, and Production Readiness
After the sample direction is approved, Rixin reviews the remaining packaging, testing, artwork, quantity, and production requirements before manufacturing can begin.
Confirm whether the formula works properly with the final container and dispensing system, then confirm packaging components, artwork, required testing, target-market requirements, and documentation.
Typical production is about 40 days after the required formula, packaging, artwork, quantity, and other production details are approved. It does not include formula development, sample revisions, packaging sourcing, design confirmation, international shipping, or customs clearance. Materials, packaging, and project complexity can affect timing.

Frequently Asked Questions
When should sampling begin?
Start when you have a product direction and enough information for Rixin to identify the suitable formula route. You can still contact us while some decisions are open.
Can I request samples before every detail is decided?
Yes. Early samples may use neutral containers, but discuss the intended package because it can affect dispensing and how the formula performs in use.
How should I provide feedback?
Send one clear response for each sample. State what you accept, what should change, how important it is, and any useful photos or references.
What is a normal revision?
A normal revision addresses agreed feedback within the original product goal. A change to the formula route, ingredient direction, packaging requirement, or another major condition may change the project scope.
What does formula approval confirm?
It confirms the agreed formula direction and accepted sample reference for the current project stage. Packaging, testing, artwork, and production requirements are reviewed separately.
Does formula approval mean production can begin?
Not by itself. Rixin still reviews the remaining packaging, testing, artwork, quantity, and production requirements before manufacturing can begin.
Discuss Your Formula and Sampling Plan
Share your product goals, current formula status, target market, packaging direction, and the feedback you need from the next sample. Rixin can review the suitable route and identify what should be confirmed before sampling begins.
