Cryotherapy is a non-invasive treatment that uses extreme cold to freeze and destroy unwanted tissue. It’s been used for decades in dermatology, and with innovations like the FreezPen, it’s now more comfortable and accurate than ever before.

The treatment works by applying a fine, targeted jet of nitrous oxide directly to the lesion - freezing the cells from the inside out. Over the next few weeks, the frozen lesion dries up, darkens, and eventually falls off naturally.
