PLLA (Poly-L-lactic Acid) is a biodegradable polymer material. Injectable products centered on PLLA microspheres differ from traditional Hyaluronic Acid (HA) "immediate physical filling" — they lean more toward "collagen stimulation": after injection, the microspheres are gradually absorbed by tissue, guiding the skin's own collagen fibers to rebuild over time, bringing more natural, gradual volume and texture improvement.

From a market perspective, regenerative filler materials have been one of the fastest-growing directions in the medical aesthetics industry over the past two years, and PLLA is a representative ingredient among them. In mainland China, PLLA belongs to Class III Medical Devices, and multiple products have been legally launched after obtaining registration certificates. For overseas brand owners and channel partners, choosing a compliant, large-scale OEM/ODM Contract Manufacturing factory is key to entering this track.

WEITAI Group was founded in 2001 and has been deeply engaged in OEM/ODM Contract Manufacturing of medical aesthetics and repair products for about 25 years. It can provide OEM/ODM customization of PLLA microsphere-based collagen-stimulating products: formula and process customization, microsphere particle size and dispersion system design, packaging design, regulatory documentation assistance, and support for export-required documents such as COA and CFS.

The factory holds ISO 13485 and ISO 22716/GMPC, with more than 110 Class II Medical Device registrations/filings, 72 invention patents, and more than 30 international patents; six bases totaling about 150,000 square meters, 65 automated production lines, Class 100,000 (including Class 10,000) GMP Cleanroom, and has served more than 1,000 brands worldwide.
