Lasers are an effective treatment option for many dermatological conditions. They can be used for deeper penetration of the skin, addressing issues like acne and psoriasis, as well as skin resurfacing.

There are two possible forms of laser treatment here:

Low-level laser therapy with a low dosage and high-level therapy with a higher dosage. “In both procedures, the high-energy, bundled light in the tissue triggers a cellular metabolic reaction in the damaged cells,” says dermatologists in Facebar YYC. “This creates an anti-inflammatory effect. With the higher-dose therapy, the blood circulation in the treated tissue is also stimulated. This ensures improved regeneration of the damaged tissue.”

There are no studies on which laser should be used best depending on the respective clinical picture. In general: “The scientific data does not allow a clear recommendation for laser therapy here,” sums up Marquaß. His conclusion: “It has to be decided individually. It is crucial to choose the most suitable treatment option for the patient from the multitude of treatment options. The development, the duration of the complaints, and possibly already existing structural changes in the tendon attachment play a decisive role here.”

Laser Treatment for Health and Beauty

There has been a veritable laser boom in the field of dermatology in recent years. The group of ablating lasers, which can treat benign skin changes, and senile warts, but also the precursors of white skin cancer, is widespread here. “Liver spots should not be treated with this, however,” warns dermatologist Gauglitz: “Whenever tissue is pigmented, i.e. brownish in color, there is a risk that black skin cancer could be behind it. The laser burns the tissue so that it cannot be histologically examined later.”

Vascular Lasers

A vascular laser is used to treat spider veins, port wine stains, or rosacea. “In the case of rosacea, for example, this produces a greyish discoloration of the red facial vessels that are enlarged here,” explains the expert. “Over the course of the following weeks, the body then breaks them down.” The principle is always the same with port-wine stains or broom rippers: “The target structure is destroyed by heat and then broken down by the body independently.” The advantage of the laser here, too, is the precise focusing of the light wave bundle: Only the affected target structure is really destroyed, in this case, the red vessel.

Because heat is used, however, there is a risk of skin burns and subsequent scarring. Expert Gauglitz, therefore, warns against going to the beauty salon for treatment – even if the treatment is significantly cheaper than at the dermatologist’s: “Good cooling is crucial to protect the skin’s surface. This is precisely what makes a laser, and thus the treatment, expensive.”

Conclusion: Lasers in Dermatology

Lasers – in dermatology, they can not only destroy cells but also act as a kind of stimulus for cell renewal. Example of wrinkle treatment on the face, hands, and décolleté: The laser beams penetrate the top layer of skin and create tiny injury points deep down. Undamaged tissues then produce new cells for fresh collagen. At the same time, the destroyed cells are transported away. The effect: the skin renews itself from within and appears younger. “Realistically, you don’t look a decade or two younger after the treatment,” says expert Gauglitz, “but fresher, more relaxed, and maybe five years younger.” Everything just doesn’t work after all.

The dermatologist has to explain this to his patients more and more often. He also advised the young woman with the pigment spots against laser treatment. As a result of the pregnancy, the young mother suffered from melasma, and hyperpigmentation of the skin. The unsightly brown spots can be removed with the laser. However, because these are hormonal, they would return immediately if there was more exposure to the sun. Even the latest high-tech lasers cannot do magic.
