The Art of Restoring Youth: A Tale of PDO Smooth Threads
Imagine the gradual, quiet rebellion of time—how the skin beneath the chin begins to soften, losing its once-firm embrace, and how those delicate lines across the neck—often called "necklace lines"—deepen into etched grooves. This is the story of one such patient, whose persistent laxity under the chin remained even after a successful lifting thread treatment. The answer lay not in another lift, but in a subtler, more regenerative approach: the use of PDO smooth threads.
PDO, short for polydioxanone, is a remarkable dissolvable suture. Loaded onto a fine needle, it is placed under the skin. Once positioned correctly, the needle is removed, leaving the thread behind. Over the next four weeks, this thread begins to dissolve, and in doing so, it triggers a profound biological response: neocollagenesis. This is the birth of new collagen, the very protein that gives our skin its tight, supple, and youthful appearance. As we age, our natural collagen stores decline, leading to thinner, less supported skin that inevitably sags. PDO threads reignite that production.
For this patient, the plan was clear. After a 15-minute application of a BLT topical anesthetic, she was ready. The procedure itself is surprisingly swift and gentle. Once the threads are placed in the correct plane—beneath the skin but above the deeper tissues—they glide into position. Most patients feel little more than a mild sensation. The key is to lay these threads like a scaffolding, or perhaps imagine a mesh beneath the surface. Every thread placed marks a zone where new collagen will soon flourish. In the submental area, we placed a dense concentration of threads to maximize the regenerative effect. The more coverage, the more collagen production.
The treatment is not a one-time event. Instead, it is a rhythmic process: repeated every four weeks for three months. The peak of collagen production from PDO threads occurs between three to six months. So, we treat monthly for three months, then allow the body time to build and solidify that new collagen. After a break, we reassess whether a second series is needed or if the results are already satisfying.
After completing the submental area, we turned to the necklace lines—those creases that can be stubborn and deeply etched. The same principle applied: place the threads directly into the crease to stimulate collagen filling. The neck’s contours require careful handling. It is essential to pull the skin taut, creating a smooth surface for precise placement. Patients may find the threads a bit uncomfortable in the neck, so we adjust in real-time. For this patient, one thread was uncomfortable, so we removed it immediately. The motto is adaptability: if a thread causes discomfort, twist and remove it on the spot.
This technique, while appearing simple, demands expertise. PDO smooth threads are incredibly versatile—beyond the chin and neck, they work wonders for acne scars, surgical scars, areas of volume loss, eyebrow lifts, and even the deep static wrinkles of the glabella (those "11" lines between the brows where fillers are not safe). But the ease of placement is deceiving. It is vital that patients seek certified, experienced healthcare professionals who have a thorough understanding of facial anatomy. A trained injector ensures both safety and optimal results.
In this story, we witnessed the power of regeneration through PDO smooth threads. The patient tolerated the procedure beautifully, and the threads were left to work their quiet magic, stimulating collagen from within. Over the coming months, the laxity under her chin and the crevices of her necklace lines would soften and fill, restoring a more youthful, refreshed appearance—not by stretching skin, but by rebuilding its very foundation.
