PDO Cog 4D Thread
4D Cog Threads with 18G / 19G needle, thread length of 100mm.
Oldream PDO 4D Cog is a barbed Polydioxanone thread with anchoring edges, spiralling 360° or in multi-directions with 1.5cm in between barbed tip. The thread are designed to maximize tensile and anchoring strength, lifting the soft issues, to achieve an effective and long-lasting result.
PDO Cog 4D uses a blunt cannula to carefully insert to a deep, subcutaneous layer of skin for a stronger anchoring effect of the skin than the regular slice cutting barbed threads. The threads are made of biodegradable polymers that degrade over a period of 9 months while inducing activity for 18-24 months.
4D Cog Thread lift can effectively enhance the soft tissue of facial droop and shape body lines. The W/L-type needle can correct errors and effectively reduce pain during operation.

PDO Cog 4D threads make it possible to reduce:
- wrinkles
- remove nasolabial folds
