The Dermatological Laser Outpatient Clinic has numerous medical laser systems of different wavelengths and pulse structures.
The clinical use of lasers in dermatology can essentially be divided into four different indication groups:

  • Treatment of vascular changes
  • ablative lasers

The following lasers are currently available for this purpose:

  • Long-pulsed dye laser (pulse duration 1.5 to 20 ms)
  • 940 nm diode laser

Congenital and acquired vascular changes to the skin and mucous membrane are treated, such as
port-wine stains, haemangiomas, angiomas (vascular nodules), dilated veins in the facial area and on the legs as well as red scars and some less common skin changes (for example lupus pernio, lichen sclerosus et atrophicus of the skin).

Like the carbon dioxide (CO2) laser , the Erbium:YAG laser is used for tissue ablation. The light from these laser types is absorbed by intracellular and extracellular water. These lasers damage or destroy tissue structures through heating or vaporisation. These lasers are used to ablate numerous benign skin changes and in the field of cosmetic and aesthetic medicine to treat wrinkles and acne scars.

Consultation hours for medical cosmetics and aesthetics

In combination with laser treatment, the uppermost layers of the skin (epidermis) are usually cooled. The intentions of this additional treatment are

  • analgesia, which makes the treatment less uncomfortable for the patient
  • thermal protection of the epidermis, which allows the use of higher therapeutic energy densities and protects against side effects such as blistering or erosion and pigment changes.

As a rule, we use cold air, which can be varied by the patient, as well as cold sprays integrated into the laser technology, which are used in a very targeted manner to match the laser pulse.

Apart from deep ablative laser treatments, which require a local anaesthetic, only superficial methods are used to relieve pain. In most cases, cooling procedures are sufficient during and after laser treatment or anaesthetic creams are also used, which are applied by the patient one to two hours before treatment.
