PLLA and CaHA fillers are bio-stimulatory injectables that prompt the body's natural collagen production for long-lasting volume restoration and rejuvenation.
As premium regenerative fillers, PLLA excels at progressive collagen renewal, ideal for overall skin tightening and long-term anti-aging with excellent biocompatibility. Cahaderm features dual advantages: immediate physical filling and sustained tissue regeneration. Its CaHA microspheres build stable support and stimulate dermal repair. Added anesthetic ensures comfortable treatment. Both products are fully metabolizable. Cahaderm stands out for instant results, while PLLA is favored for gradual, natural skin rejuvenation.
Bioha’s PLLA outperforms ordinary counterparts with uniformly sized microspheres. It triggers mild, controlled collagen regeneration, cuts granuloma risks and delivers natural, long-lasting lifting effects. Unlike competitors’ products needing on-site dilution, our pre-mixed Cahaderm combines CaHA, cross-linked HA and lidocaine in one formula. It avoids extra mixing steps and effectively reduces post-injection redness and swelling. Both fillers are fully biodegradable, and ensure safer, more comfortable and reliable aesthetic results for diverse clinical demands.
Unlike HA fillers which provide immediate volume, PLLA and CaHA are biostimulators. They work by stimulating your body's own natural collagen production to gradually restore volume and improve skin structure over time, leading to longer-lasting and more natural-looking results.
CaHA fillers offer some immediate volume due to their gel carrier, with collagen stimulation following for results lasting around 12-18 months. PLLA fillers provide more gradual results that appear over a few months as new collagen develops, but these results can last two years or more with a proper treatment plan.
Most patients report only mild discomfort, which is managed with a topical numbing cream; many fillers also contain lidocaine (a local anesthetic). There is minimal to no downtime, and patients can typically return to their normal routines immediately, although some mild swelling or bruising may occur.
The number of sessions varies by product and individual goals. CaHA often requires a single session for immediate lift and ongoing collagen stimulation. PLLA typically involves a series of initial injections, spaced a few months apart, to achieve the desired gradual enhancement.
Yes, both PLLA and CaHA are considered safe and are biocompatible with the body. The most common side effects are mild and temporary, including redness, swelling, bruising, or tenderness at the injection site, which usually resolve within a few days. Your physician will discuss all potential risks during your consultation to ensure they are the right fit for you.
