How long do the results of PDO Threads last?
As already mentioned above, the PDO Threads are synthetic threads produced by absorbable polydioxanone. The disintegration and absorption time of polydioxanone ranges from 4-6 months. This means that the time that we benefit from the positive effects of edema and skin firmness, is perhaps a little less.
What are the advantages and disadvantages of PDO Threads?
The advantage of PDO thread is that if there are no hypersensitivity or allergy reactions, the process can be repeated quite often and in various areas at a time.
When it comes to the disadvantages, one major disadvantage of this method is that if there is any allergy or hypersensitivity to the thread material or any reaction of a foreign body, then the thread cannot be removed, since it is found longitudinally in the subcutaneous tissue.
Unfortunately, we are not able to know in advance the cause of this allergic reaction or hypersensitivity to PDO Threads This case –when arises- can be treated in a quite difficult and painful manner both for the patient and the doctor.
A second disadvantage is that in contrast to common belief, when 4-6 months elapse and the thread is completely absorbed, then no collagen TYPE I is produced, as a result of the inflammation. Collagen TYPE I is a new collagen (i.e. a structural molecule of tissues that provoke skin rejuvenation and firmness). If the PDO threads could trigger the production of collagen TYPE I, we could then be talking about a long-term skin rejuvenation through collagenoses process.
Simply said, the absence of collagen TYPE I means that the treatment result lasts for a relatively limited period of time without contributing in future skin firmness or texture.
The total absence of collagen TYPE I production after the application of PDO Threads have been results of a study, which was presented for the first time by the Dermatology Professor Alexander Turkevich and the Plastic Surgeon Henry Delmar at the World Congress of Aesthetic Plastic Surgery and Anti-Aging that took place at Paris, on January 2015.
Are the PDO Threads a safe choice of treatment?
The PDO Threads are used as alternative facial skin rejuvenation techniques in several countries. However, they have not been FDA approved in the US, since it is a non-entirely certified product for its safety and effectiveness. Studies are being conducted for this new technique and we are awaiting the results’ announcement.
