La Cryotherapy Facial
For a brighter face recourse may be had to dermatological cryotherapy using the cold treatment purposes. La cryotherapy creates a heat minishock on the surface of the skin which accelerates the diffusion of active ingredients associated with exfoliating and rejuvenating purposes.
What is cryotherapy for skin?
For dermatological cryotherapy is defined as the treatment of skin lesions, or to lighten facial discolorations, and mucous membranes through the freezing of tissues in the dermis. It is based on the effect on tissues by low temperatures through extra and intracellular ice crystal formation and which consist essentially in the destruction of keratinocytes to -30° e of melanocytes to -3°.
Cryotherapy can be very helpful in treating Seborrheic Keratosis-large sizes multiple entities that develop after thirty years. In this case, avoiding general anesthesia, cryotherapy can be used to reduce the thickness of Actinic by preparing the next curettage, or through multiple sessions, causing progressive detachment.
How does the cryotherapy:
The cold causes cellular necrosis through a sequence of mechanisms that can be summed up:
- Formation of intracellular ice crystals that cause lysis cell mechanics
- Abnormal electrolyte concentration cell phones causing irreversible changes in the ph of the skin
- Ice crystal formation in extracellular spaces, with increased osmotic gradient and recall of water out of the cell, which eventually collapsed:
- Thermal shock with alterations of cellular lipoproteins.
Local circulatory alterations complete district necrosis. In fact, when the local temperature drops to -50° C occur phenomena of stasis, venous thrombosis and tissue capillary.
The dermatologist then thanks to the action of liquid nitrogen will burn your imperfections which will go immediately to necrosis forming a crust which soon will fall. And good not to sunbathe on the exposed portion for at least a month.
