lAight is an innovative, non-invasive therapy for acute abscesses including hidradenitis suppurativa/ acne inversa.






For lAight®, we use a combination of various electromagnetic waves, including fractions of the visible light spectrum. Potentially harmful wavelengths of UV-A and UV-B are not utilized. A wide range of studies can be found for the efficiency and safety of the single components of the lAight® therapy, which have been researched individually. The NICE study – conducted at the University Medical Center of the University of Mainz – investigated the effect of a purpose-built combination therapy, called lAight® therapy, as a treatment for hidradenitis suppurativa*.


The NICE study found that a regular treatment regime of the inflamed lesions utilizing lAight® therapy reduces the number of lesions and significantly improves the quality of life for the majority of patients (measured by the DLQI scale). Patients also describe an instant, noticeable pain reduction following the treatment, as well as an accelerated healing process and an improved scar texture.


Minor side-effects occur rarely, in some cases a temporary skin irritation can appear on the treated skin areas*. There are only a few known contraindications, for example, skin cancer. Therefore, lAight® is a suitable long-term therapy for hidradenitis suppurativa. Whether lAight® is an adequate treatment for an individual patient, will be determined by the attending physician.


With the consent of the patient, the progress of all therapy utilized, as well as photographic documentation, can be recorded and reviewed. The individual patient can access our lAight® Portal and look into his course of treatment, as well as find useful information about hidradenitis suppurativa.

What physicians say about lAight®

  1. “The lAight® therapy is a promising alternative for the treatment of hidradenitis suppurativa and I am delighted to be able to provide it for my patients. We can treat the disease now without surgical interventions, long-term and non-invasive. The results of the lAight® therapy are very positive and my patients are relieved to have found a working treatment.”

    Dr. Zeynep Potente, Aestetic and plastic surgeon.

  2. “It is my goal to give HS patients a normal life. I offer a special consultation hour for patients with chronic abscesses and hidradenitis suppurativa. After only 7 months I already witnessed so many distinct and visible successes that I am very happy to have included this gently new form of therapy into my practice. The overwhelmingly positive feedback is a great encouragement for me.”

    Dr. med. Uwe Kirschner, Dermatologist and venereologist

  3. “We are familiar with the ordeal of the HS patients. We are happy to be able to provide a treatment that is a good supplementation to a surgical intervention.”

    Gerhard Rothenaicher, Surgeon

  4. “The combination of the lAight® therapy with a special treatment of wounds in our WundZentrum offers a good possibility and great therapeutic option for patients with HS.”

    Dr. Peter Kandzorra, Surgeon

The lAight® therapy is an innovative, alternative treatment method that is currently not a part of medical services compensated by statutory health insurance (in Germany). The treatment is carried out by a physician. The mechanism of action and tolerance of the therapy have not yet been sufficiently scientifically researched with regard to conventional medicine. The statements about the effect and tolerance of the therapy, are based on previous experience of the therapy usage and preceding results of the trial carried out by the University Medical Center of the University Mainz. Due to the fact that every individual is different and medical success by definition cannot be guaranteed, before beginning treatment, patients are informed by the attending physician, about possible risks and contraindications, as well as costs, so they have ample time to decide if what we offer is the best course to take towards recovery.
