Intense pulsed light in the treatment of non-aesthetic facial and neck vascular lesions: report of 85 cases.

BACKGROUND: Intense pulsed light (IPL) treatment is one of the most effective procedures for patients with non-aesthetic vascular lesions in addition to signs of skin photoageing, and it has been reported as very successful in the treatment of telangiectasias, spider nevi, erythrosis, and above all, rosacea and poikiloderma. Its use is based on the principle of selective photothermolysis, which exploits the haemoglobin absorption peak among its range of wavelengths.

OBJECTIVE: The aim of this study is to assess the efficacy and safety of intense pulsed light in treating non-aesthetic vascular skin lesions, especially with regard to poikiloderma of Civatte and rosacea.

METHODS: A total of eighty-five patients, 64 women and 21 men, with 63 non-aesthetic vascular lesions (28 Poikiloderma of Civatte and 35 rosacea), 22 pigmented lesions (UV-related hyperpigmentation of solar lentigo-type) and four precancerous lesions (actinic keratosis, AKs), were treated repeatedly with IPL for 2 years. The patients received a mean of five treatments (range 4-6) at 3-weekly intervals. They were evaluated via clinical observations and professional photographs were taken before each treatment and after 2 weeks, 4 weeks, 3 months, 6 months and 12 months. The outcome of the IPL treatments was evaluated by four independent dermatologists, who were not informed about the study protocol, and who assessed the performance of IPL by dividing the results into four categories: no results, slight improvement, moderate improvement and marked improvement.

RESULTS: All the patients showed improvements in their overall lesions: 72 lesions (80.9%) achieved a marked improvement, 14 lesions (15.7%) achieved a moderate improvement and three lesions (3.4%) achieved a slight improvement. The results of the 63 non-aesthetic vascular lesions in Rosacea and Poikiloderma of Civatte were: 51 with a marked improvement, 10 with moderate improvement, whereas only two lesions achieved a slight improvement. The improvement of all four actinic keratoses was marked whereas the 22 pigmented lesions obtained a marked improvement in 17 cases, a moderate improvement in four cases and a slight improvement in one case. No undesirable effects were observed.

CONCLUSIONS: Our study confirms how by minimizing side-effects, time and costs, IPL can be effective and safe for the treatment of non-aesthetic facial and neck vascular lesions.
