A split-face comparison study of pulsed 532-nm KTP laser and 595-nm pulsed dye laser in the treatment of facial telangiectasias and diffuse telangiectatic facial erythema.

Background And Objectives: Pulsed 595 nm and 532 nm lasers can effectively diminish or eliminate facial telangiectasia. We performed a split-face, single-blind, controlled, comparison study in an effort to determine their individual and comparative efficacy.

Study Design/materials And Methods: Fifteen patients were treated using a 595-nm PDL on one side of the face and a pulsed 532-nm potassium-titanyl-phosphate (KTP) laser on the other.

Patient satisfaction and reported long-term therapeutic efficacy associated with 1,320 nm Nd:YAG laser treatment of acne scarring and photoaging.

Background And Objective: Nonablative laser treatments have become increasingly used for the treatment of acne scarring and photoaging. While nonablative laser treatments are more convenient and relatively safer than ablative laser resurfacing, efficacy and patient satisfaction with the level of improvement of textural abnormalities in acne scarring and rhytids associated with photoaging needs further study. DESIGN/MATERIALS AND METHODS: Structured interviews were performed with 34 patients from a referral-based academic practice who each previously received a series of 6 monthly treatments with a 1,320 nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser for treatment of acne scarring or photoaging.

Topical 5-aminolevulinic acid combined with intense pulsed light in the treatment of photoaging.

Background: The adjunctive use of 5-aminolevulinic acid (5-ALA) with intense pulsed-light (IPL) treatments has been suggested to increase the benefit of IPL for photoaging; however, to our knowledge, no controlled trials have been performed.

Design: A prospective, randomized, controlled, split-face study was designed. Twenty subjects participated in a series of 3 split-face treatments 3 weeks apart in which half of the face was pretreated with 5-ALA followed by IPL treatment while the other half was treated with IPL alone.

Clinical evaluation of enhanced nonablative skin rejuvenation using a combination of a 532 and a 1,064 nm laser.

Background And Objectives: Improvements in the physical signs of photoaging can be achieved by non-invasive laser resurfacing procedures. To evaluate the effectiveness and safety of the Nd:YAG 1,064 nm and KTP 532 nm lasers for non-invasive skin rejuvenation.

Study Design/patients And Methods: Subjects requesting non-invasive skin rejuvenation underwent two treatments with the 532 nm laser to one side of the face and with both lasers to the other side, followed by three treatments with the 1,064 nm laser to both sides.

Reduction in injection pain with botulinum toxin type B further diluted using saline with preservative: a double-blind, randomized controlled trial.

Background: Injection with botulinum A exotoxin reconstituted with preserved saline has been shown to be less uncomfortable than injection with the same toxin reconstituted with preservative-free saline.

Objective: We sought to determine whether injection with botulinum toxin type B is similarly less painful when preservative-containing saline is used to further dilute the product.

Methods: We conducted a double-blind, randomized controlled trial.
