Our practice in Vienna is the Austrian reference center for Asclepion Lasers. We are therefore working with the latest and most powerful lasers on the market. We also train medical colleagues in the field of laser technology.






What is a laser and how does it work?

Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. Laser beams are electromagnetic waves or amplified light. Although most laser beams are not visible, some can be seen depending on the wavelength. The wavelength also determines which skin changes the laser affects. Depending on the laser, the beam can be red (small vessels), dark (tattoo removal) or water (scars). When removing skin alterations, the target is the water contained in the tissue. The laser beam penetrates the top layer of skin and is absorbed by the water in the human skin. The water evaporates immediately, releasing energy and pulling tissue particles with it at supersonic speed. A slight pop can be heard.


In our practice we offer various laser procedures for a wide variety of results:

  • Erbium Dermablate (MCL31) ablative
  • Erbium Dermablate (MCL31) fractionated
  • QuadroStarPROYELLOW
  • ThunderMT von Quanta Systems


 We would be happy to advise you on the right laser for your requirements.

Erbium Dermablate (MCL31):

The laser beam is aimed at the skin area to be treated. It penetrates the top layer of the skin and is absorbed by the water in the human skin. The water instantly evaporates, releasing energy, dragging tissue particles with it at supersonic speed. A slight pop can be heard. The tissue is removed delicately and precisely in layers. The advantage over electrocautery, for example, is that the adjacent skin remains intact. With fractional ablation, the laser light is split into several light beams by special optics. A grid is created, which means that a large part of the skin between the MicroSpots remains untreated. The treatment regenerates the tissue very quickly from the healthy skin islands in the grid. The skin is firmed, and the formation of new collagen is stimulated. The result is a healthy and fresh appearance.



The laser beam is directed onto a visible vessel. The target for the laser is the red blood pigment haemoglobin. The effect of the laser beam causes the vessel to heat up and damages the vessel wall. This leads to sealing and degradation of the vessel. Most vessels are no longer visible after one treatment.

ThunderMT from Quanta Systems:

The Thunder Laser works with wavelengths that are considered the gold standard for many treatments in dermatology and aesthetic medicine. A state-of-the-art device with two laser wavelengths, 755 nm and 1064 nm. The special case is that the laser can be used as a single or combined laser with patented combination technology. This combination is currently the gold standard for hair removal, dermatological vascular lesions and skin rejuvenation treatments. Nail fungus can also be treated with this laser. The treatment can be individualized thanks to the two wavelengths and the ability to adjust each one individually.


What can the Erbium Dermablate (MCL31) do?

The erbium laser (MCL31 Dermabalate) treats wrinkles, acne scars, crow's feet, cholesterol deposits (xanthelasma) and other unsightly skin alterations. With the laser, precise work is guaranteed during skin ablation and rejuvenation. An elegant alternative to conventional dermabrasion, which mechanically scrapes tissue; or electrocautery, which burns tissue.



How does it work: The type and size of the affected skin area is key for defining the correct course of treatment. For small wrinkles, scars, or small moles, only a few minutes is required. For a facial fractional ablation (skin rejuvenation), about half an hour is necessary. One session is usually enough. For the treatment of scars or problems that are located deeper in the skin, several treatments are usually necessary. However, this will be discussed in advance in each individual case.

What advantages does the DERMABLATE MCL 31 offer over other methods?

When ablating or removing birthmarks, the advantage over the otherwise common electrocautery is that the adjacent skin remains intact and very precise work is possible. A lot of heat is generated during electrocautery and the surrounding healthy tissue is also destroyed. The risk of unsightly scars is higher, and the healing process often takes longer.

With fractional ablation, the laser light is split into several light beams by special optics. A grid is created, which means that a large part of the skin between the MicroSpots remains untreated. In this way, regeneration from the healthy skin islands can take place more quickly compared to a procedure in which the entire epidermis is removed.


What can the QuadroStarPROYELLOW do?

Thanks to its yellow wavelength of 577 nm, the QuadroStarPROYELLOW is the gold standard for vascular treatments such as rosacea, couperose, telangiectasia, spider naevi, cherry angiomas, port-wine stains and spider veins. It enables fast, effective, and safe treatment with reduced side effects. Compared to conventional KTP (532 nm) this laser offers a more targeted effect on the vessels and thus fewer side effects.


What advantages does the QuadroStarPROYellow offer compared to other procedures?

Thanks to the lower melanin absorption (compared to 532 nm) it is also possible to treat darker skin types. In addition to the standard handpiece, the QuadroStarPROYELLOW offers a scanner with an integrated skin cooling for treating larger areas. As a result, the patient feels less warmth and the treatment is overall a more pleasant experience.


What can the ThunderMT do?

The Thunder laser is a very powerful device, which is equipped with two wavelengths Alexandrite 755 nm and Nd: YAG 1064 nm. This innovative laser is the ideal solution for extremely fast and painless hair removal. Thanks to the technology, hair removal can be done all year round and is not limited to the seasons with little sunshine. Furthermore, the laser can be used for an efficient treatment of dermatological vascular lesions, treatment of nail fungus and skin rejuvenation. The Thunder laser can be used particularly for deeper and larger vessels (e.g. spider veins) or hemangiomas. The Nd: Yag 1064 nm is also the optimal wavelength for nail fungus treatment. Laser treatment is an important treatment option for nail fungus.


What advantages does the ThunderMT offer compared to other methods?

The special feature of the Thunder laser is that it is actually two lasers in one. This innovative technology makes the Thunder MT laser unique. The first shot already damages the blood vessel / hair root and changes its color. In this way, the vessel / hair is recognized even better by the second laser and a significantly better result is achieved. Significantly better than if only one of the two wavelengths were used.

Thus, most hair removal applications can be performed without any problems and with good success. The advantage is that the dose and combination of both lasers in the laser can be individually adapted to the skin type. This can also be used in summer and for darker skin types. The risk of side effects is significantly lower. The laser also has an integrated cooling system. Qool-air is an exclusive skin cooling system for the Quanta System Thunder laser. The powerful system brings maximum treatment comfort through the pleasantly perceived cooling.


What other treatments can be done with the available lasers?

Blemishes and small wrinkles are very annoying for many patients. Problem areas can be covered with make-up. One way to fix the cause is with a chemical peel. In addition to chemical peelings, a great alternative for blemished skin or small wrinkles is laser peeling with the erbium laser. Pharmaceutical ingredients can also penetrate better after the peeling. I use this method in the cosmetic field for the introduction of active ingredients to tighten and reduce hyperpigmentation. The treatment on the face takes around 20 minutes. One session is recommended initially, then more as required. The skin is slightly red after the treatment but after a few hours the face shines with a new, fresh glow.

The QuadroStarPROYELLOW is used for small vessels in the face (rosacea). The laser can also be used to treat warts. Some people develop haemangiomas or small strawberry angiomas on their bodies during their lives, which are perceived as bothersome. These can also be removed very easily using a laser.


What should you pay attention to when treating with a laser?

Before any laser treatment procedure - in addition to cleaning the skin - a medical diagnosis must be made. Skin type is assessed in the diagnosis and the likelihood of treatment success is discussed with you and contraindications are excluded. As a rule, individual moles can be removed in the same way. How severe the pain is during the treatment depends largely on the extent of the treatment. Local anaesthesia is possible for moles, but not required for peelings or scar treatments. As a rule, an anaesthetic ointment is sufficient beforehand for sensitive patients, and then supplemented with a soothing care cream (e.g., aloe vera). Anaesthesia is not necessary for treatment with the QuadroStarPROYELLOW. Subsequent, constant sun protection for four to six weeks is important.


Which side effects can occur?

Mild side effects such as redness disappear within a few days. It should be noted that a slight crust is part of the healing process in some treatments. Post-inflammatory hyperpigmentation (PIH) can occur with dark skin types and especially when exposed to the sun. Therefore, constant light protection must always be ensured. The cold season is particularly suitable for laser treatments.


How much does this type of treatment cost?

For the treatment of a single wrinkle or a nail-sized mole, around 150-175 euros (including practice fee) should be budgeted - around 60 euros for each additional mole. A fractional treatment of the face costs up to 450 euros. For the treatment of vessels in the face (cheeks and nose), the cost is around 350 euros. When treating strawberry angioma (haemangiomas), an individual price will be charged depending on the amount. The stated values ​​are for guidance only. You are welcome to make an appointment at our practice for a consultation.

Hair removal with the ThunderMT laser costs between EUR 70 (upper lip or chin) and EUR 530 (entire legs) per session, depending on the zone. Further details on treatment can also be found here.

  • I traveled from London to see Dr. Johannes Bisschof for wrinkle treatment. I was extremely impressed with my wrinkle treatments. He has a very 'natural look' approach and after everyone asked me why I look younger and more relaxed I will definitely have it done again. I have also asked him advice on my skin texture and he suggested 2 creams and my skin has never looked this good. I feel 10 years younger. I can highly recommend him!
