A single-blinded randomised controlled study to determine the efficacy of Omnilux Revive facial treatment in skin rejuvenation.

To determine the efficacy of Omnilux Revive facial treatment in skin rejuvenation, twenty-three volunteers received randomised 20 min treatments three times a week for three weeks to one half of their face, with the untreated side acting as control. Regular assessments were carried out, focusing on parameters of subject satisfaction, photographic assessments, skin elasticity (Cutometer) and skin hydration (Corneometer CM825). Ninety-one percent of the volunteers reported visible changes to their skin. Blinded photographic evaluation reported a clinical response in 59% of the subjects. Objective analysis failed to show statistically significant changes in skin hydration or elasticity. The Omnilux Revive LED lamp is a safe alternative non-ablative skin rejuvenation treatment.

Incidence of side effects after laser hair removal.

BACKGROUND: Despite the widespread use of lasers for hair removal there are few data published on the incidence of side effects from this treatment. OBJECTIVE: The aim of this study was to generate data on a large number of patients receiving laser hair removal to obtain an accurate assessment of the incidence and type of side effects resulting from treatment. METHODS: A multicenter prospective study of patients presenting for laser hair removal was conducted to determine incidence of side effects in relation to skin type and laser or lasers used. RESULTS: Laser hair removal is associated with a low incidence of side effects that are self-limiting in the majority of cases. The highest incidence of side effects was seen in patients with darker skin treated with the long-pulsed ruby laser. CONCLUSIONS: Laser hair removal is inherently safe. For darker Fitzpatrick skin types the long-pulsed neodymium:yttrium-aluminum-garnet laser is preferred to the ruby laser.

Treatment of resistant port wine stains with the V Beam pulsed dye laser.

BACKGROUND AND OBJECTIVES: Pulsed dye lasers (PDL; 585 nm, 0.45 millisecond) are the treatment of choice for port wine stains (PWS). However, clearance rates vary widely and are in many patients incomplete. The objective of this prospective pilot study was to investigate the effects of a long pulse-duration 595 nm PDL (V Beam, Candela Laser Corporation, Wayland, MA) on previously treated PWS to ascertain whether further lightening can be obtained. Treatment response was assessed subjectively (photographs) and objectively with noninvasive techniques (reflectance spectrophotometer and spectrophotometric intracutaneous analysis scope (SIAscope)). STUDY DESIGN/MATERIALS AND METHODS: Twelve adult patients with congenital PWS each had four test patches with different spot sizes, fluences, and pulse widths carried out. The test area with the best response was selected and two laser treatments were performed at weeks 8 and 16. Photographs and measurements with a reflectance spectrophotometer and SIAscope (Astron Clinica, Cambridge, UK) were performed at baseline, before each treatment and at final review at week 24. RESULTS: Of the nine patients who completed the study three patients showed a good response (51-75% lightening), which was supported by measurements with the reflectance spectrophotometer and the SIAscope. A further three patients had fair improvement (26-50% lightening) and three patients had a minor or no response (0-25% lightening). In two patients a discrepancy between the degree of clinical response and some of the objective measurements was noticed. CONCLUSIONS: The 595 nm V Beam PDL appears to achieve further lightening of therapy-resistant PWS in the majority of patients (67%). Both reflectance spectrophotometer and SIAscope appear to permit assessment of objective treatment responses. Results require confirmation in larger studies.
