mophore gel (Kleresca SKR-treatment) on the patient’s face and subsequently treated with a blue light-emitting multi LEDlamp (447 nm) for nine minutes (Kleresca , Balerup, Denmark). The treatment was repeated four times once weekly. No other medication was applied during and after treatment. The patient developed a mild erythema immediately after the first treatment, that regressed 1 week after the final session. After 5 weeks, the patient showed a marked reduction of the inflammatory reaction and an overall improvement of the large-pored skin type (Fig. 1b). Rosacea is a very common, often underdiagnosed, chronic inflammatory skin disease, which usually manifests in middle-aged women. Long-term treatment with a combination of both topical and systemic therapeutics is often necessary to control the disease, but not all patients do tolerate or do accept systemic treatment. The PALT-system has the CE mark for the treatment of acne and skin rejuvenation. A “biophotonic” mode of action via the induction of photomodulation to the skin by the transfer of energy has been described, but the exact underlying mechanism is still not fully understood. Our observations suggest that PALT may also function as a new topical, nonsystemic option for the treatment of papulopustular rosacea.
