Like any procedure, there are risks. Often multiple subcision procedures are needed depending on the type of scars, and severity. Regardless, it is a brilliant procedure in the correct hands for anchored, and tethered scars. Risks are proportional to the type and aggression used .1. If NOKOR subcision 5-10% risk of seroma or haematoma. Early intervention, easily corrected .2. Paradoxical scaring, I have seen this before. Due to more subnormal fibrosis. Rare, but can be corrected .3. Scar at entry point, rare. 4. Infection - rare.5. Bruising, common. More so if aggressive Nokor used, or extensive in certain anatomical areas. 6. Others...etc.. will be discussed by your treating dermatologist. Do not underestimate this treatment. In the correct hands, in the correct setting, it will outperform any laser or energy device as one's skill set is used to manually remove or should I say IMPROVE that scar type. Dr Rapaport is probably one of the most skilled in this procedure on this forum, and I respect his viewpoints, and agree with his comments. Dr Davin Lim, Dermatological surgeon. Acne scar specialist.
