Firmosa PLLA Mono & Screw Threads — Professional Aesthetic Threads

Firmosa is a premium Korean aesthetic brand offering a full range of PLLA (Poly-L-Lactic Acid) Mono and Screw threads with ultra-sharp needles, designed for professional practitioners seeking precise and minimally invasive skin rejuvenation and contouring treatments.

Mono Thread — Collagen Stimulation & Skin Rejuvenation

Mono threads are smooth, single-strand threads with no barbs or hooks. They do not provide a lifting effect. Their primary function is to stimulate collagen production, improve skin texture, reduce fine lines, and enhance overall skin quality. Ideal for surface-level rejuvenation across the face and body.

Mono Screw Thread — Collagen Stimulation with Mild Tissue Support

Mono Screw threads feature a helical (spiral) structure that allows for better tissue integration and anchoring compared to standard mono threads. They provide mild tissue support and volumizing effect through enhanced collagen stimulation, while still not delivering the same degree of mechanical lifting as barbed cog threads. Best suited for areas requiring added volume and skin firmness.
