Fractional Non Ablative Photorejuvenation

Description

Physiological ageing (chronoaging) linked to the passing of time is a natural and inevitable aspect of life that affects all the functions, organs and tissues of the human body, including the skin.
This natural process is accelerated by external environmental factors (ultraviolet rays, smoke, alcohol, pollution, etc.), which make up what is known as photoaging.

The clinical effects include thinning, transparency and sagging of the skin, wrinkles, uneven colouring, pigmentary and vascular marks and irregularities in the skin surface.

Recently, there has been much talk about the need to develop new technologies for use in the cosmetic field for treating wrinkles, post-acne scars and pigmentary alterations, improving skin texture and achieving facial firming. This ongoing research into technological innovation derives from an increasing demand for improvements in appearance and quality of life.

The advantages of non-ablative photorejuvenation

A modern approach that employs minimally invasive procedures to treat the signs of skin ageing is now available.
Non-ablative photorejuvenation is a beneficial, non-invasive solution for improving the appearance, colour and texture of the skin without lengthy post-op recovery periods, and without compromising work and social activities.

Numerous laser and light sources are used for non-ablative photorejuvenation. Each different wavelength selectively reaches a preferential target within the skin structure acting at a specific depth in the skin. The aim is to achieve vascular and pigmentary normalisation, and the stimulation of neocollagenasis. The correct laser or light source must be selected to adapt the treatment to the needs of each patient. The methods to be used may be fractional or otherwise. In this section we shall address the “non-ablative fractional” methods. To find out more about the non-fractional methods, consult the respective section.

Non-ablative fractional photorejuvenation uses laser sources that penetrate the skin in depth without vaporising part of it. The advantage of such sources is that they do not produce any partial or total removal of the epidermis, thus eliminating the problems associated with this practice, namely having to wait for the reepithalisation of the epidermis. In fractional treatment the laser generates targeted and controlled denaturation of the tissue on deep columns, separate and above all surrounded by intact tissue. This latter aspect is the main novelty of the fractional treatment over the traditional one. As soon as the denaturation of the tissue columns is produced, the repair process begins, leading to the formation of new collagen and the removal of the dyschromic components. This process is enhanced and accelerated by the presence of resources that arrive rapidly from the parts of healthy tissue surrounding the areas denatured by the laser.

The advantages of this method are its non-invasiveness and rapid recovery times, without having to wait for the (albeit limited) reepithalisation times. The drawbacks are that it is less effective than more invasive methods (such as “Ablative Fractional Photorejuvenation”) and poor results on deeper wrinkles.

This is the context in which we can place the DOT1540 platform, since it can be equipped with two fractional light sources (Er:Glass at 1540 nm and Nd:YAP at 1340 nm), a pulsed light handpiece (5 interchangeable filters with emission at 500-1200 nm, 520-1200 nm, 550-1200 nm, 600-1200 nm, and 650-1200 nm), and a source with infrared emission (IR 750-1800 nm).
