HISTOFREEZER – PORTABLE CRYOSURGICAL UNIT – for removing benign skin lesions
The HISTOFREEZER kit – contains a spray filled with a gas mix – dimethyl ether, propane and isobutane, of different dimensions.
The evaporation of the gas produces a temperature of -55 °C.
The action mechanism is based on the fact that different types of skin cells vary in sensitivity when frozen.
The epidermal keratinocytes are often more sensitive when frozen than the collagen and fibroblasts network from the subjacent dermis. The keratinocytes necrosis leads to the appearance of a blister, vesicle.
The complete healing will take place in 10-14 days, with spontaneous re-epithelialization, without leaving any scars on the skin.
