When used cosmetically, PDO smooth threads help tighten and smooth the skin by boosting collagen production and making one’s face look more youthful and rejuvenated. PDO smooth threads are dissolvable sutures that are extremely thin (the size of a strand of hair) and made of a neutral substance that’s very inert to our bodies. It’s the same material that has been used for stitching wounds for decades. When doctors noticed the improvement in skin texture, collagen, and firmness after a sutured cut had healed, the novel idea came about to load this suture thread onto a needle to help place it under the skin, specifically for skin improvement. This procedure worked so well that PDO threads are now one of the most popular procedures for skin enhancement.
There are also different shapes of PDO threads that are now available. The most popular types are molded, barbed, smooth, and twist threads. Smooth threads are the original thread utilized and continue to elicit collagen production over the six months of absorption after they’re administered. Twist threads are similar to smooth, except they have a spiral shape that fits more thread into a smaller area, making it more condensed.
