Cryotherapy/freezing treatment uses liquid nitrogen to freeze the skin cells until they die. The tag tends to shrivel up for a few days before eventually falling off.
The freezing treatment normally involves 5-10 seconds of the liquid spray, applied with a break of 1-2 minutes between treatment cycles. The duration and number of treatment cycles depend on the skin type and the nature of the problem.
For small skin tag removal, cryotherapy or freezing treatment is a quick low priced option.
