Presentation Croma PDO Barb II 4D 20G 60 mm threads are an innovative aesthetic medicine solution to combat skin sagging. Manufactured by Croma laboratories, these absorbable threads feature a multidirectional barb system acting like tiny hooks. They firmly anchor the tissues for optimal repositioning. Each box contains 12 ready-to-use threads, ideal for reshaping contours without major surgery.
Composition
& rheology Material: Polydioxanone (PDO), a biocompatible and fully absorbable polymer. Specifications: 20G needle, 60 mm thread length. Technology: Multidirectional barbs (4D) for maximum tissue grip. Packaging: Box containing 12 lifting threads.
Indications
This device is designed for the treatment of tissue sagging. It is particularly recommended for restoring volume in the middle and lower thirds of the face, redefining the jawline, lifting eyebrows or cheekbones, and smoothing the submental area. It can also be used on certain body areas requiring a tightening effect, often in combination with other aesthetic techniques.
Posology Implantation must be performed by a qualified practitioner. After local anesthesia of the targeted area, the threads are inserted into the deep dermis or subcutaneous tissue. The procedure generally takes between 15 and 40 minutes. The number of threads used depends on the clinical assessment and the patient's specific needs.
Results are visible immediately and improve over the months thanks to fibroblast stimulation, before the complete absorption of the thread.
Conservation

Check the expiration date before any intervention. Contraindications Known allergy to polydioxanone (PDO). Active skin infections or inflammations on the area to be treated.

FAQ
How long do the effects last? Although the thread is absorbed in a few months, the induced neocollagenesis prolongs the lifting and firming effect well beyond the disappearance of the material. Is the treatment painful? The procedure is considered minimally invasive.
Performed under local anesthesia, it causes minimal discomfort and allows for rapid recovery with no visible scars.
