Laser in dermoaesthetics

"The laser is a good therapeutic option in benign, superficial and non-malignant dermatological pathologies".


The laser is a light source in which the radiant energy is in the form of photons and waves capable of producing special biological effects. 

In the field of Dermatology, they are increasingly used, constituting a good treatment alternative as well as the only option in some pathologies. 

The most recent machines are so precise that they generate millimetric lesions that selectively damage the tissue of interest without affecting other skin structures. 

Thus, they can correct pigmentation disorders, vascular alterations or eliminate the traces of aging without causing major damage, or hardly any pain.

When is dermo-aesthetic laser indicated?

Laser therapy is not valid for everyone. Tolerance to this form of energy is individual and depends on each individual's skin type.

The indication of the type of laser to be used on a given patient will depend on professional judgment. The patient should be informed of the benefits and risks of the treatment.

Most frequent indications:

  • Spider veins
  • Cuperosis
  • Superficial varicose veins
  • Scars

Do you have any of these problems?

How is the laser treatment performed?

There are three components that have a specific capacity to absorb the laser: hemoglobin (blood element that transports oxygen), water and melanin (substance that pigments the skin). They are called chromophores.

These targets capture light to a greater extent and this is transformed into heat. When a temperature of about 100 degrees Celsius is reached, the target is vaporized.

This phenomenon is known as photothermolysis and is the mechanism of action of this form of energy. To reach the different therapeutic objectives, the laser points at one chromophore or another.

To coagulate and eliminate epidermal vascular lesions, such as angiomas (red, blue or purple birthmarks) or spider veins, couperose or even some varicose veins and scars, the target is hemoglobin.

The target is melanin when it comes to treating pigmentation disorders: sun spots, age spots (lentigines), tattoos (colored inks also capture laser light) and hair, since hair follicles also produce this coloring substance.

Vaporizing water is the goal when you want to rejuvenate your face. In this case, the superficial layer of the skin (the epidermis) is burned and the formation of new skin tissue is promoted (ablative remodeling).

It is also possible to use a laser that penetrates deeper and stimulates the production of collagen without eliminating the epidermis (non-ablative remodeling), although the results of this less aggressive technique are not perceptible until after more than a year.

In theory, aiming at these targets seems simple. But in practice, it is not so simple. To prevent thermal damage from injuring other areas and producing burns, scars or alterations in skin color, the wavelength, duration and surface area of the emission must be modulated. In this way, the tissue is more or less penetrated and the objective is reached while respecting other structures.

The Clinic's Dermatology Department has incorporated a Candela Ibérica GentleLASE laser, which is a long pulse Alexandrite laser used for photoepilation.

Laser hair removal produces a heating of the hair matrix (responsible for hair production) which causes the inactivity of the follicle in the production of hair. The number of sessions depends on the area treated, the density of the hair and the cycle of the hair itself. For maximum results four to six sessions are usually needed.

This procedure is performed to remove unwanted hair, although it is not only used for aesthetic purposes, but also as a solution to very prevalent medical problems such as hirsutism from different endocrine pathologies, hirsutism from medications, pseudofolliculitis, etc.

This treatment is performed by dermatologists and nurses with great experience in the field of Dermatology, with seriousness, rigor and always from the deep knowledge we have of the skin, the fundamentals of laser and the prevention and treatment of potential adverse effects.
