Peeling con TCA – Nitrogen


The word means peeling peeling action, move or technically ecdisis. A peel is a dermatological act intended to remove some skin thickness to obtain, first, a dermal regeneration and subsequently epidermal.

The peeling is practiced since ancient times. Egyptian skin rubbed with powdered alabaster; Turks skin became scorched with fire; Indians and urine applied to the skin.

The agent used for peeling should not be toxic to the body.

Any cream or acidified solution may have a peeling effect. It is then a sputtering effect of removing the horny layer, or a simple granular layer exfoliation.

Superficial peeling limit their main action on the surface of the epidermis. Deep peeling reach the dermis and must be performed by specialized physicians. Their action results in a new formation of collagen and elastic fibers, histological support clinical visible skin improvement.

Depending on the item or product used are classified Physical and Chemical Peeling:

1. Criopeeling:
– Criopeeling carbon dioxide (CO2) or anhydrous dry ice. The gas is contained in a shell provided with valve whose opening causes the output of a white powder spray, carbon dioxide, which is contained in a porous bag, and alone or mixed with acetone in a gauze applied to the skin rubbing.

– Criopeeling with nitrogen (N2) fluid. Liquid nitrogen is provided in thermal bottles and extracted in a special vessel. A strip of cotton which is then applied to the skin is embedded.

Liquid nitrogen can also be introduced into containers which are used as a pistol.

– Criopeeling to criofluorano. Criofluorano sprayers have replaced jet ethyl chloride. They are handled very simply pressing the cap.

2. Fotopeeling:
– Fotopeeling monochromatic light. A monochromatic light source, the type of Xenon lamp, filtered through a plate that lets one single wavelength, previously selected based on the level of dermal penetration desired.

– Fotopeeling coherent light. They are the laser peeling. Each operator uses the device to which it is most accustomed. The goal is to perform a set of contiguous points of impact for a desepidermización. There are important oedematous reactions.

3. Peeling microsurgical
In 1990, a new surgical technique was presented for treating nevus of OTA by desiccated skin.

Under an increase of ten, and a shallow incision perpendicular to the skin using a No 11 scalpel blade so that binding of the papillary dermis to the reticular dermis is reached is performed.

An identical second incision, parallel thereto, at a distance of 0.7 mm to 1 mm is made. The tip of this thin strip of skin is taken with forceps and cut at its base with a pair of scissors.
