Sequential treatment with intradermal incision (intracision) and 2,940-nm Er:YAG laser for chicken pox scars

This is a case report on the sequential treatment of chicken pox Scars with intracision and a 2,940nm Er:YAG laser. For three Korean patients, intracision was used to sever abnormal fibrous bands at the Scar base and induce subdermal blood pooling, promoting new collagen synthesis and improvement in Scar depression. This was followed by 2,940nm Er:YAG laser (eccentric aluminum garnet) treatment at one-month intervals. Significant clinical improvement was observed in all three patients. The researchers reported that collagen band severance and subdermal hematoma formation by intracision promoted Scar improvement, and subsequent laser treatment further enhanced the improvement. The research team reported that sequential combination of intracision and 2,940nm Er:YAG laser could be effectively utilized for the treatment of chicken pox Scars.
