Laser rays act by using controlled photovaporization to remove the top layer of the skin, i.e. the epidermis and depending on the aim sought, may reach down as far as the superficial dermis: it is a form of controlled burning.
The different types of laser used in facial resurfacing are essentially UltraPulse or scanning CO2 lasers and Erbium lasers.
Computer control of the depth of vaporization is achieved through: the number of passes of the laser ray, the energy emitted and its density. Control depends on the significance of the blemish to be corrected, the size of the area to be treated and the outcome sought.
The surface layer that is removed restores itself as a result of the natural effects of healing.
This means there is a healing period during which the skin remains fragile and is in need of dedicated care.
It is this restoration of the surface layer of the skin that creates a smoother look: this smoothing has the advantage of more or less erasing the blemishes that we want to treat.
Moreover, the dermo-epidermal healing process will entail a degree of tightening of the cutaneous skin, a real skin “stretching” effect which is variable and more or less significant depending on the individual concerned.
