3-in-1 Therapy

The TREVIOLUX combines three applications in a single device. At a peak wavelength of 630 nm, the light penetrates deep and effectively into the tissue during irradiation.

Conventional PDT

Conventional photodynamic therapy (PDT) is an established method for the treatment of actinic keratoses and basal cell carcinoma, the two most common forms of non-melanoma skin cancer.

PDT is based on a well-established procedure in which a photosensitizer, typically methyl aminolevulinate (MAL), is applied topically. The drug binds selectively to the malignant cells. A special light is used to destroy the malignant cells without damaging the surrounding healthy tissue.

In addition to proven efficacy, the treatment offers excellent cosmetic results with minimal scarring. The proprietary Soft Start / Pulse modes can reduce the discomfort of the treatment. This can help patients with increased pain sensitivity.

Compact Daylight PDT

The Compact Daylight PDT is a unique, effective, and extremely beneficial approach to treatment. Inspired by the principles of the Daylight PDT. A controlled and virtually pain-free treatment - best suited for superficial actinic keratoses. Photodynamic therapy (PDT) with Methylaminolevulinate has been shown to be useful in the treatment of certain forms of non-melanocytic skin cancer. This modern method can be performed using both cold red light (cPDT) and daylight ("Daylight PDT"; DL-PDT).

We would like to introduce you to our approach: Compact Daylight PDT with the TREVIOLUX (Compact Daylight PDT) or Artificial Daylight PDT (ADL-PDT). In addition to conventional PDT, the TREVIOLUX also lets you perform Compact Daylight PDT all year round, regardless of the weather conditions and with little to no pain.


Skin rejuvenating effects of PDT for photoaged skin have been well-documented in several clinical trials. The rejuvenation mode simplifies the use of PDT for aesthetic applications.

Compact Daylight PDT, also known as Artificial Daylight PDT, is a form of photodynamic therapy that mimics the continuous light exposure of natural daylight.

Unlike conventional PDT, which can be painful, Compact Daylight PDT uses a longer duration of light at a lower intensity. This approach, when combined with a specific photosensitizer application, is designed to reduce the pain of the treatment. The lower-intensity light activates the photosensitizer over a longer period, which can be more tolerable for patients and result in less discomfort during the procedure.
The TREVIOLUX utilizes red light at a wavelength of 630 nm because this spectrum offers an ideal penetration depth for treating certain skin conditions. Red light can penetrate deeper into the skin compared to blue or green light, which makes it more effective for reaching and activating the photosensitizer in the target tissue. This deeper penetration is crucial for the effectiveness of the treatment, as it ensures that the therapeutic effects reach the intended depth within the skin.
The TREVIOLUX skin rejuvenation process uses red light to activate a photosensitizer applied to the skin. This activation leads to a series of photochemical reactions that can help repair and rejuvenate the skin. The treatment stimulates the production of new collagen and elastin, which are essential components for maintaining skin structure and elasticity. As a result, patients may experience a reduction in the appearance of fine lines, wrinkles, and other signs of aging, resulting in a more youthful complexion.
