How to Choose a Freeze-Dried Skincare Spheres Manufacturer

Choosing a freeze-dried skincare spheres manufacturer starts long before the first quote arrives. The clearer your specification, the more accurate the quotes, the fewer the surprises during development and the faster you can reach a product ready for launch.

This guide gives you the practical tools to do that: a specification sheet, an RFQ template, a framework for comparing quotes and a protocol for evaluating samples. Examples from our EVIK™ LyoPearl range show what real skincare sphere specifications look like.

Before You Send an RFQ: Test a Standard Sphere First

Freeze-dried skincare spheres, often called beads or lyobeads, are dry spheres designed to hold a measured amount of active ingredients and dissolve in water or a suitable activator. If you have never worked with this format, handling a real sample is a practical first step toward developing a meaningful specification.

Our five standard EVIK™ LyoPearl beads are available as research and evaluation samples. Each demonstrates a different way to specify an active ingredient.

Test the samples in your intended base or activator and record their dissolution, appearance, texture and compatibility. Use those observations to complete the specification sheet below.

The Specification Sheet: What to Tell a Manufacturer

A useful specification defines the formulation, physical characteristics, performance expectations, packaging and production volumes. The following table provides a starting point for your project brief.

If molecular weight matters for your formulation, read our guide to hyaluronic acid in skincare to understand why it can influence product performance.

The RFQ Template: Ten Sections to Include

A complete request for quotation helps you obtain comparable responses from different manufacturers. Include the following ten sections in your RFQ.

How to Compare Quotes From Manufacturers

The lowest unit price does not necessarily represent the best overall value. Compare each quote against the same formulation, quality, packaging and delivery requirements.

The Sample Evaluation Protocol

When samples arrive, evaluate them consistently. Use the same conditions for every manufacturer so your results provide a fair basis for comparison.

1. Inspect on arrival. Check the seal, packaging integrity and presence of desiccant where applicable. Confirm that the spheres are intact, uniform and the expected color.
2. Test dissolution. Use the liquid and quantity intended for your product. Record the time required to dissolve each sphere under consistent conditions.
3. Assess feel and finish. For suitable cosmetic evaluation samples, assess texture, residue, spreadability and absorption according to the intended use.
4. Check compatibility. Combine the sphere with the intended serum or activator and observe any separation, color changes, clumping or other unexpected behavior.
5. Run a storage check. Store sealed samples under the proposed storage conditions and evaluate them at predefined intervals. Use a validated stability protocol for formal product decisions.
6. Record and share results. Document the lot, test conditions, observations and deviations. Send clear feedback to the manufacturer to guide the next sample round.

Consistent handling helps keep your evaluation results meaningful. Our guide to lyophilized bead handling covers storage, transfer and practical handling considerations.

What to Expect After You Choose a Manufacturer

Once you select a manufacturing partner, the project typically progresses through several stages. The exact sequence depends on formulation complexity, testing requirements and production volumes.

1. Evaluation samples. Use standard beads to establish a benchmark for appearance, dissolution and handling.
2. Proof-of-concept batches. Develop small batches around your active ingredient and target dose to establish initial feasibility.
3. Compatibility assessment. Evaluate the formulation, protective excipients, intended activator and relevant performance requirements.
4. Pilot production. Produce a representative batch to evaluate process consistency, packaging and market-testing requirements.
5. Commercial-scale manufacturing. Move to the agreed production scale with documented quality controls and batch testing.

How EVIK Responds to Your RFQ

EVIK manufactures and supplies EVIK™ LyoPearl skincare beads. Our process is designed to turn a liquid formulation into a dry, single-dose sphere while protecting the active ingredients through formulation, freeze-drying and packaging.

In our process, each active is formulated with suitable protective excipients. Droplets are frozen in liquid nitrogen at −196°C to form spheres, after which ice is removed under vacuum. The resulting beads are counted into vials under controlled humidity and sealed with desiccant.

Learn more about the process on our technology page.

Our experience includes 15 years of lyophilized reagent bead production, an ISO 13485-certified facility for diagnostic contract manufacturing and processes designed to meet applicable Good Manufacturing Practice standards. Quality and regulatory requirements for a specific cosmetic project should be confirmed during project scoping.
