Optical treatments for acne

Light-based treatments for acne are becoming increasingly commonplace in dermatology. This article reviews various light approaches in acne therapy. Methods are discussed from an anatomical and a functional perspective. The emphasis is on the practicality of treatment as well as the pros and cons of various devices. Also, a review of the recent literature is presented. The article is intended to give the reader a panoramic view of this still-young and developing area. Most likely, light-based acne treatment will receive more popularity as dermatologists learn how to integrate this type of therapy within the context of more established drug agents.

Photodynamic Therapy in the Treatment of Rosacea

BACKGROUND

Rosacea is a common disease, with an estimated prevalence of 5-10%. Established systemic and topical treatment is often effective but requires continuous medication.

AIM

We report the outcome of photodynamic therapy (PDT) in 4 patients with rosacea.

METHODS

Prior treatment consisted of standard treatment with tetracycline and metronidazole. The treatment was however either ineffective or the patients were dissatisfied with the need for continuous treatment. The patients all received standard treatment with PDT.

RESULTS

The treated skin cleared in 3 of the 4 patients. Treatment with light alone did not appear to have any effect. In one of the patients there has been no relapse during a 9-month follow-up. In 2 patients, remissions lasted 3 months, during which time no additional or supplementary treatment was used.

CONCLUSION

Our observation suggests that PDT may play a role in the future treatment of selected cases of rosacea.
