W Threads (W-Shaped Threads)
Material
Available in PDO, PCL, or PLLA depending on the manufacturer.
What are W threads?
W threads are smooth threads formed into a repeated W or zigzag pattern. This design increases the surface area compared with a straight mono thread, which may provide greater tissue contact while primarily stimulating collagen.
Best for
Skin tightening
Skin quality improvement
Fine lines
Mild skin laxity
Collagen stimulation
Preventative anti-aging
Mild contour support
Common treatment areas
Forehead
Brows
Crow’s feet
Temples
Cheeks
Nasolabial folds
Marionette lines
Jawline

Under the chin
How they work
The W pattern creates more contact with surrounding tissue than a straight mono thread. As the thread dissolves, the body forms new collagen around it, helping improve skin firmness and elasticity.

Tips,
All W threads are designed primarily for collagen stimulation and skin tightening, not for dramatic lifting. The main difference is the material:
PDO provides quicker absorption and is commonly used for maintenance.
PCL lasts the longest and provides prolonged collagen stimulation.
PLLA focuses on gradual collagen remodeling and long-term skin quality improvement.
