Auro PCL Bidirectional Cog 4D Absorbable Thread Lip Cheek Face Remove Wrinkles

Cog threads are essentially mono threads, but with barbs deigned to hook to the underside of the skin. These barbs are usually either cut or molded as part of the thread and purposed as a support structure to lift sagging tissues. Unlike smooth mono threads, cog threads do not require anchoring points. In the case of cog threads, collagen formation will occur around both the threads and their barbs; making it most effective for jawline lifting and slimming.

Polucaprolactone (PCL) threads is one that can last up to more than 2 years. This is because, the chemical bonds and structure in PCL are stronger and more complex, hence it takes a much longer time to be dissolved completely. The slower rate of degradation of the PCL threads also makes it ideal to be inserted to the surrounding tissues over an extended time; achieving a longer lasting result. PCL is also known to be very potent at stimulating collagen production as compared to PDO or PLLA. Once dissolved, the material breaks down into ordinary substances and even after the thread has dissolved, collagen production can last for up to one year.
