About PDO Mono Threads

PDO (Polydioxanone) offers complete biocompatibility with no known allergens, backed by decades of use in surgical sutures. Mono threads stimulate collagen production and improve skin texture, tone, and elasticity. They are naturally absorbed by the body within 6 to 9 months.

PCL threads, milky white in color, use higher-quality Polycaprolactone material with greater hydrolysis resistance. Effects last 16–24 months, with significant results for skin firming and wrinkle reduction.

Mono threads are the easiest to operate — an excellent choice for practitioners of all experience levels.
