What is Cauterizing moles.
Adrian Rios, director of Unilaser Medical
‘Mole cauterization’ is a term used to describe several methods of mole removal, including chemical techniques, electrosurgery and the use of lasers.
Electrosurgery in the cauterization of moles causes the sudden release of electrons at the tip of an electrode, ionizing free atoms in the air and transforming the space between the tip of the electrode and the tissue into an electrical conductor.
The energy released during electrosurgical cauterization of moles is converted into heat, light (in the form of sparks) and sound.
In the case of lasers, ‘evaporation’ would be a more appropriate term to describe their effect, which is similar to cauterization of moles.
Depending on the type of laser, a selective increase in the temperature of the mole’s pigments can be achieved. Lasers, which can be visible or invisible to the human eye, have the ability to concentrate energy more selectively, absorbed by pigments such as hemoglobin or melanin.
A blue light laser would be predominantly absorbed by the red pigment, while a red light laser interacts with other colors in the visible spectrum but not with water or similarly colored tissue.
Visible lasers, like our vision, do not ‘see’ or absorb water.
Infrared lasers, depending on their proximity to the visible spectrum, may absorb pigments to a lesser extent. Infrared lasers farther from the visible spectrum work similarly to a microwave, agitating water molecules.
An advantage of laser over electrosurgery for “mole cauterization” is its ability to concentrate greater amounts of energy in shorter periods of time, allowing for effects not achievable with cauterization or cryosurgery, because a shorter exposure time reduces heat expansion.
Precise exposure time adjustments allow evaporation without reaching carbonization levels, like electrosurgery mole cauterization.
In addition, the laser offers greater control over the procedure, allowing for precise removal of small residual areas, a significant advantage over cauterization of moles with electrosurgery and cryosurgery.
The ability to adjust power provides more consistent and reliable results between different cases.
In short, while electrosurgery involves the manipulation of electrons, laser treatment focuses on photons, which tend to be more directional and carry higher energy.
This underscores the physical reason why the laser is often preferred over other methods of mole cauterization: energy, defined as the ability to do work, when applied selectively, can achieve superior results.
We will explain a little more about the electric current part:
Radiofrequency cauterization is a medical process where electric current is used to destroy tissue, such as a mole.
This process begins when the electric current comes into contact with the tissue and then travels through the human body to the point of lowest voltage, being redirected to ground through a conductive plate.
There are two methods of cauterization: bipolar, which releases electrons between two terminals, and monopolar.
When an electrosurgical device is connected to a power source, it receives a voltage that flows through the electrical network.
The electrical outlets involved have one input with the voltage supplied by the network and another with zero voltage.
The difference between these two voltages is what generates the current.
In terms of frequency, alternating current operates in cycles, oscillating between two directions, creating waves measured in Hertz (Hz).
While a typical household appliance operates at 60 Hz, which generates a faradic effect on nerves and muscles, the frequencies used in electrosurgery range between 300,000 and 400,000 Hz, generating greater resistance when in contact with tissue and avoiding deep ionizing effects.
This high frequency level produces a primarily ‘electrolytic’ effect: the incoming electron current accelerates tissue ions without completely separating them, allowing them, in the presence of a high voltage, to interact with the electrons in the cells, generating heat and preventing excessive damage.
The circuit created by the electrosurgery concentrates the destruction at the tip of the instrument, while the rest of the body presents less resistance, as long as the circuit is closed correctly and completed to ground.
This is ensured by the use of a conductive plate attached to the patient’s skin, which directs the electrons towards the ground.
If the plate shifts, the flow of electrons can be abruptly interrupted, burning the tissues where the current is concentrated.
In summary, an electrosurgery device consists of a generator that converts low-frequency alternating current to high-frequency alternating current, an electrode or pencil that focuses the energy, and a conductive plate that completes the circuit through the body.”

The importance of recognizing moles.
It is essential to understand what moles actually are.
Moles
We can assume that moles are pigmented tissues according to their constitution.
Melanocytic moles are composed of clusters or nests of pigment cells that are increased in number.(1)
In childhood, they are mostly flat and as the years go by, the face tends to become raised and less colored.
The smallest moles are usually between one and 7 millimeters.
Nasal dorsum: Closure is usually difficult. Laser shaving can prevent flaps.
Nostrils: Difficult flaps and primary closure are avoided
Center of the cheek: It is possible to vaporize them if they are superficial and less than 7 millimeters in diameter.
Ear pavilions: Respond well to laser vaporization, laser shaving is only possible in sessile lesions
Eyelids: Cutting is avoided with the consequent area of hair loss
Scalp, eyebrows: Laser shaving is generally used. Alopecia areas are avoided.
