DERMARIS dermatological photodynamic therapy (PDT) lighting system
DERMARIS is a dermatological lighting system dedicated to photodynamic therapy (PDT). Designed to meet the requirements of PDT protocols, it supports dermatologists in delivering their treatments, both in private practices and specialized medical centers.
DERMARIS a lighting system designed for photodynamic therapy (PDT)
Dynamic phototherapy relies on precise protocols that require specially adapted lighting. Control over light characteristics, uniformity of light emission, and light stability are essential factors in supporting dermatological treatments using PDT. The DERMARIS was specifically designed to treat actinic keratosis (AK) using dynamic phototherapy (PDT).
Photodynamic therapy (PDT) is a medical technique used to destroy pre-cancerous tissues through the combination of photosensitizing substances and a dedicated light source. Designed to integrate seamlessly into the clinical environment, DERMARIS provides dermatologists with a reliable solution tailored to the implementation of photodynamic therapy treatments, while addressing the clinical and organizational constraints of dermatology practice. This PDT lighting system delivers a constant intensity of 20,000 lux and provides a wide, uniform treatment area (20 cm in diameter). The irradiance spectrum of DERMARIS covers all absorption peaks of the photosensitizing molecule used to eliminate pre-cancerous cells.

Key advantages of the DERMARIS PDT lighting system
- Ease of use: the light is compact and space-saving, making it easy to set up for the patient(less than 2 minutes). The dome is easy to turn off, as you simply tilt it upwards to switch it off.
- Unmatched patient comfort: The treatment operates silently, ensuring a calm and comfortable experience.
- Long-term use: more than30,000 treatments possiblewith a treatment time of treatment time of 2 hours
- Sustainable lighting: DERMARIS offers a service life of60,000 hours and can be used as examination lighting. Furthermore, no consumables are required during illumination.
Note that some recent studies now show results achieved in just one hour of treatment; learn more in our dedicated article.
Clinical studies
DERMARIS has been evaluated in clinical studies, with results demonstrating the following outcomes (study conducted on 38 patients):
Effectiveness:
- 58%of patients had no more KA lesions 3 months after treatment.
- 32% ofpatients required a second AWL-PDT treatment.
- 10% ofpatients had one to four KA lesions after 2 treatments.
Clinical studies
Pain:
- 33 of the 38 patients(87%) experienced no pain during treatment.
- Five patients(13%) rated their pain level as 1 on a scale of 1 to 10.
Post-processing:
The discomfort experienced during the six days following treatment was rated:
- Nonexistent(34% of patients)
- Mild(63% of patients)

As a private dermatologist, I use dynamic phototherapy to treat actinic keratoses.
Daylight therapy is an effective treatment, but using the DERMARIS lamp from SURGIRIS allows you to perform an equivalent treatment in your office with the same results. This treatment can be performed regardless of weather conditions. This technique can be comfortably performed in your office, both in summer and winter, without being dependent on rainy periods or extreme heat.
I personally own two Dermaris lamps for better treatment of two "keratosis fields" in a small dedicated room. Given the frequency of this condition, this equipment is very cost-effective and useful for patients.
