Frequently Asked Questions

Get answers to common questions about PDO Smooth Threads for Collagen.

PDO Smooth Threads are absorbable polydioxanone filaments inserted superficially into the treatment area. They create a scaffold and trigger a controlled wound-healing response, prompting new collagen formation over weeks and months for progressive skin tightening and improved texture.

Discomfort is usually mild. We apply topical numbing and local anesthesia to minimize sensation. Patients commonly feel tugging or pressure during placement and mild soreness afterward, which is typically managed with over-the-counter pain relief and brief rest.

You may notice an immediate subtle lift, but collagen remodeling drives visible improvement over 4–12 weeks. Results often continue to improve up to 3–6 months, with effects lasting around 12–18 months depending on individual factors.

PDO Smooth Threads can be used on cheeks, jawline, brows, nasolabial folds, perioral areas, under-eyes, neck, décolletage, and hands. Treatment plans are customized based on skin laxity and aesthetic goals during your consultation.

Common temporary effects include bruising, swelling, and mild discomfort. Rare complications can include infection, thread visibility, or asymmetry. Choosing an experienced provider and following pre/post-care instructions significantly reduces risk.

Many clients achieve noticeable improvement with a single session, but some benefit from staged treatments. Maintenance or touch-ups are often recommended every 12–18 months; the exact number depends on goals and initial skin condition.
