PLLA vs. HA vs. CaHA: Choosing the Right Material Category
Last reviewed: · Published by FRIDERM Pro (Jinan Xilemei Import and Export Co., Ltd.)
For buyers new to this product space
Direct answer: PLLA, HA and CaHA are three different material classes with different general mechanisms — this page explains the category-level distinction to help you decide which product category to explore, in general industry terms, not as a FRIDERM-specific clinical claim.
Three material classes, general framing
| Material | General class | FRIDERM product lines |
|---|---|---|
| PLLA | Collagen-stimulating biostimulator — generally understood in the industry as working by stimulating the body's own collagen production over time, rather than providing immediate volume. | Fri Hydro, Fri Volume, Fri S, Fri X |
| HA (cross-linked) | Volumizing filler — generally understood as providing more immediate volume/structure through the gel itself. | FRIGGEL Petit/Classic/Grand, Friderm B Body, Friderm Contour |
| CaHA | Mineral-based biostimulator — generally understood as combining some immediate volume with a collagen-stimulating effect over time. | HyaCaHAP, Innoshe |
The descriptions above are general, widely-referenced industry framing of each material class — not a clinical claim about any specific FRIDERM SKU's duration, onset or outcome. We do not publish FRIDERM-specific clinical study data on this site; request documentation per SKU via Quality & Documentation.

Once you know which material category fits your sourcing need, use the category page itself (PLLA, HA, CaHA) to see the actual SKUs, and How to Compare Product Specifications once you're comparing specific SKUs by unit, volume or pack count.
FAQ
Which material is "better"?
This page does not make that claim — they serve different general purposes (immediate volume vs. collagen stimulation vs. a mix of both) and the right choice depends on your own market's demand, not a universal ranking.
Can I compare a PLLA SKU directly against an HA SKU by price or volume?
Not directly — they're different material classes with different units and mechanisms. Compare SKUs within the same material category using How to Compare Product Specifications.
Does FRIDERM Pro have clinical data showing how long each material lasts?
We do not publish SKU-specific clinical duration data on this site. Request documentation per SKU rather than relying on general industry duration claims.
