The erbium:yttrium-aluminium-garnet (Er:YAG) laser has recently been used in the fractional resurfacing of photo-aged skin. Our study evaluated the results after one single session of fractional resurfacing with Er:YAG. Thirty women participated in the study, with an average age of 46 years, skin types from II to IV, and wrinkle grades I to III. The 2,940(More)
BACKGROUND Becker's naevus (BN) may represent a distressing cosmetic handicap and a challenging issue regarding treatment. OBJECTIVES To compare clinical and histopathological findings of patients with BN treated with two different lasers: an erbium:yttrium-aluminium-garnet (Er:YAG) system vs. a neodymium:YAG (Nd:YAG) laser. PATIENTS AND METHODS In this(More)
The laser treatment of port-wine stains (PWS) has as a main aim the irreversible damage of ectatic vessels. Blood content of the subcutaneous venous plexus in PWS can be increased by a factor of seven or more, compared to that of the normal skin. The venous blood velocity ranges from 0.1-1 mm/s in capillaries to approximately 22 mm/s in larger vessels of(More)
BACKGROUND Melasma is a difficult entity to treat. Topical creams or chemical peels offer some success, and the newer fractional lasers have also been proposed to be useful. This three-armed study compares topical creams, CO2 ablative fractional resurfacing and the combination of both modalities. PATIENTS AND METHODS Thirty females with melasma, mean age(More)
Rhytides represent an aesthetic problem for a large percentage of the population. Many methods, both noninvasive and invasive, have been used for the treatment of wrinkles. Recently, the long-pulsed 1064-nm Nd:YAG laser has been shown to enhance dermal collagen synthesis without damaging the epidermis. The purpose of this preliminary study is to evaluate(More)
BACKGROUND AND OBJECTIVES Ablative fractional resurfacing shows promise for skin resurfacing and tightening and also to improve treatment of epidermal and dermal pigmentary disorders. This study aimed at determining any correlation between epidermal ablation and effects on the dermis when using an Er:YAG laser in ablative fractional resurfacing mode. (More)
BACKGROUND The recent adaptation of laser technology in plastic and dermatologic surgery has provided a means to reduce efficiently the irregularities of the surface of the skin. Previous studies have analyzed the short- and medium-term clinical and histologic results of two laser systems: the Sharplan 40C SilkTouch and the 5000C Coherent Ultrapulse with(More)
To date there is no information that evaluates, from the patient's point of view, the experience of undergoing CO(2) laser skin resurfacing. This article investigates the outcome of laser resurfacing for various cutaneous problems with respect to the patient's expectations and experiences and the surgeon's opinions. Patients were entered into the study(More)
Studies have reported short-term and long-term (1-year) findings for laser skin resurfacing. Two of the most popular systems used for this procedure, the continuous-wave Sharplan 40C SilkTouch system and the pulsed Coherent 5000C UltraPulse system with a computer pattern generator, were previously compared for a range of follow-up times up to 1 year, using(More)
BACKGROUND Intense pulsed light (IPL) sources have been reported in non-ablative photorejuvenation, but the excellent histological findings do not always coincide with the clinical results and patient satisfaction index (SI). METHODS Ten female patients (two forehead, four periocular and four perioral), ages ranging from 28 to 46 years, skin types II-IV,(More)
