TATTOO OR SCAR REMOVAL TECHNIQUE Russian patent published in 2009 - IPC A61N1/32 A61B18/12 

FIELD: medicine.

SUBSTANCE: for removal of skin defects including tattoos and scars, skin is exposed to variable electric field with high-frequency discharges between epidermal layer and a needle electrode. The epidermal layer is burned out in sectors 2 cm² and less as distributed along the defect region without processing a skin area between removed sectors. After healing, the remained defect regions are burnt out in the specified way. Said operations are performed until the defect is burnt out completely in the entire area. Herewith the electrode and the epidermal layer are spaced 0.01 to 20 mm. The discharge voltage is 20 to 10000 V, and frequency is 1 to 1000000 discharges per a second. Prior to exposure, the epidermal layer is pre-cooled to 5-50°C.
