Weitai can provide OEM/ODM Contract Manufacturing for Cosmetic products (Lyophilized Powder, Mask, Essence, etc.), Class II Medical Device (Medical Dressing, gel, etc.), and Class III Medical Device Injectable Filler products (Sodium Hyaluronate, PLLA, PCL, Hydroxyapatite, etc.).

Weitai's freeze-dried platform covers ten formats: lyophilized powder, emulsion, floc, microspheres, spheres, crystal ice gel, tablets, eye masks, face masks and oil-gel. Active systems from PDRN, copper peptide and astaxanthin to recombinant collagen and peptides can all be customized under cosmetic OEM/ODM private label.

Freeze-drying uses low-temperature vacuum drying to lock actives into a dry, sterile matrix. Products stay stable with little or no preservative and retain more activity; they are reconstituted and applied fresh at point of use, which cuts oxidation and deactivation in water-based systems-ideal for peptides, PDRN, collagen and other high-potency actives.

The solvent is the matching reconstitution liquid, usually a sodium hyaluronate essence water or a dedicated buffer that restores the powder into a serum at point of use. The consumer injects it into the powder vial, gently shakes and applies directly or with an infusion device-fresh mixing preserves activity.

Lyophilized masks freeze-dry active essence directly onto a dry sheet with no preservative soak. Soaking in solvent or pure water instantly turns it into a fresh essence mask. Activity is better preserved and the mask is gentler-suited to sensitive skin and high-efficacy care-while being easier to ship and store.

Standard lyophilized powder and emulsion sets usually start at around 1,000-5,000 PCS; masks, eye masks and tablets vary slightly with packaging and process. The exact MOQ depends on formula, specification and packaging. We support small-batch sampling up to mass production-contact us for a tailored quote and sampling.

You can customize active ingredients and levels, powder-plus-solvent set specifications, vial/blister/box packaging, scent and skin feel, as well as a brand-exclusive formula. We work from a sample, a brief or an idea, and provide cosmetic filing and registration support with compliance documents.

The dry, sterile freeze-dried matrix makes it hard for microbes to grow, so formulas can use little or no preservative. Activity is sealed in by low-temperature vacuum freeze-drying and restored at point of use through powder/liquid separation or single-dose vial and sachet packaging, keeping actives as fresh as possible.

Powder is the classic high-activity vial format; emulsion self-emulsifies into a nourishing milk suited to dry/sensitive skin; microspheres wrap actives in micron beads that burst and release on contact for extra stability; spheres are concentrated single-dose beads for precise intensive care; floc carries high-load peptides with fast penetration; crystal ice melts to water for hydration and soothing; tablets are portable and precise; eye masks, face masks and oil-gel cover eye contour care, intensive sheet treatment and oil-based anti-aging. Our formulators can help you choose by target benefit, skin type and usage scenario.
