To have a brighter face may use the cryotherapy dermatological that uses the cold to aim treating. Cryotherapy creates a thermal minishock on the skin surface that accelerates the diffusion of the active ingredients associated with exfoliating and rejuvenating purposes.
What is cryotherapy for skin?
For cryotherapy dermatology it means the treatment of skin lesions, or for toning facial blemishes, and mucous membranes through the freezing of tissues of the dermis. It is based on the effect on the skin tissue caused by low temperatures through the formation of extra- and intracellular ice crystals and which consist essentially in the destruction of keratinocytes in -30 ° and melanocytes to -3 °.
The cryotherapy can be very useful in the treatment of multiple seborrheic keratoses mediogrande of entities that develop after thirty. In this case, avoiding general anesthesia, cryotherapy can serve to reduce the thickness of keratosis preparing them to the next curettage, Or, through multiple sittings, causing the progressive detachment.
How does cryotherapy: The cold causes cell necrosis through a sequence of mechanisms that can be summarized:
- Formation of intracellular ice crystals which cause the mechanical lysis of the cell
- Abnormal cellular concentration of electrolytes with consequent irreversible changes in the skin ph
- Formation of ice crystals in extracellular spaces, with an increase of the osmotic gradient and recall of water from the cell, that ends collapsed:
- Thermal Shock with alterations of cellular lipoproteins.
Local circulatory changes complement the district necrosis. Indeed, when the local temperature drops to -50 ° C are carried out phenomena of stasis, venous thrombosis and capillary tissue.
The dermatologist then thanks to’ liquid nitrogen action will burn your imperfections that will soon become necrotic forming a crust which soon will fall. And well not get the sun on the exposed part for at least a month.
