PCL is commonly used in petit procedures, especially in collagen-stimulating fillers known as Ellanse. It induces stronger skin fibrous tissue formation than PDO, which is commonly used in thread lifting. And PCL threads are also commonly used in embedding lifting.
But I heard cog threads made with it had come out, so I tried the procedure.
I’ll organize and write only the points I personally felt. 1. Because it was thicker than PDO cog threads, it hurt a bit when first inserted. (It’s a one-time pain, so it’s okay.) 2. Due to the nature of the material, it has elasticity, so the strong lifting effect is limited. 3. Due to the nature of the material, it has elasticity, so the foreign-body sensation is not very noticeable. 4. They say it lasts for 2 years. The downside is that when the threads get old, the skin inevitably sags, and toward the end, it may not help much with lifting. 5. In reality, the areas where the threads were densely placed gained volume, and the skin texture is also soft and moist. (A lot of skin tissue was generated.)
I had a design that pulls along an axis from the scalp to the anterior cheek, so many threads were inserted. As the anterior cheek volume filled in, my dry-looking impression improved, the nasojugal groove/Indian wrinkle improved by about 60%, and there was also an effect of the skin being pulled slightly upward.
I’ve also heard that adding a few threads every 2 months helps with maintenance.
Anyway, rather than a lifting effect, I saw good results as a volume-enhancing effect, and next time I’m thinking of trying cog threads made with PLLA.
