OBJECTIVE We evaluated synergistic efficacy and safety of combined topical application of Botulinum Toxin Type A (BTX-A) with fractional CO2 laser for facial rejuvenation. METHODS Twenty female subjects were included for this split-face comparative study. One side of each subject's cheek was treated with fractional CO2 plus saline solution, and the other side was treated with fractional CO2 l...

BACKGROUND Fractional CO2 laser is an effective treatment for scars, but most patients complain about sharp burning pain, even after the application of lidocaine ointment. This study analyzed the impact of a vibrating device to nonpharmacologically reduce the acute pain of laser treatment, in accordance with the gate control theory of pain management. METHODS This is a prospective study perfo...

OBJECTIVE To evaluate the efficacy and feasibility of thermo-ablative fractional CO2 laser for the treatment of symptoms related to vulvo-vaginal atrophy (VVA) in post-menopausal women. METHODS From April 2013 to December 2013, post-menopausal patients who complained of one or more VVA-related symptoms and who underwent vaginal treatment with fractional CO2 laser were enrolled in the study. A...

OBJECTIVE Microablative fractional CO2 laser has been proven to determine tissue remodeling with neoformation of collagen and elastic fibers on atrophic skin. The aim of our study is to evaluate the effects of microablative fractional CO2 laser on postmenopausal women with vulvovaginal atrophy using an ex vivo model. METHODS This is a prospective ex vivo cohort trial. Consecutive postmenopaus...

BACKGROUND AND OBJECTIVE Q-switched laser treatments are considered the standard method for removing both regular and traumatic tattoos. Recently, the removal of tattoo ink using ablative fractional lasers has been reported. Ablative fractional CO2 laser and q-switched ruby laser treatments were used in a split-face mode to compare the safety and efficacy of the two types of laser in removing a...

Ablative fractional carbon dioxide (CO2) lasers have been widely used for several types of cosmetic dermatosis. A number of previous studies have evaluated this technique in animals or human beings by observing morphologic changes using an invasive modality such as skin biopsy. In this study, we assessed in vivo skin changes after CO2 ablative fractional laser treatment in a mouse model using n...

BACKGROUND Keloids are abnormal wound responses characterised by excessive deposition of collagen and glycoprotein. They are both aesthetically and symptomatically distressing for most of the patients. There are reports of keloid management with pulsed dye laser (PDL), fractional carbon dioxide (CO2) laser and neodymium-doped yttrium aluminium garnet (Nd:YAG) laser individually and also in comb...

INTRODUCTION Chronic vulvar pain and burning remains one of the most perplexing problems faced by practicing gynecologists. AIM To evaluate the effectiveness and safety of the application of micro-ablative fractional CO2 laser to the vulvar vestibule in the management of patients with vulvar pain from vestibulodynia or genitourinary syndrome of menopause. METHODS Patients (N = 70) underwent...

BACKGROUND Recently, photodynamic therapy (PDT) has been shown to be an effective first-line treatment for actinic keratosis (AK). However, a major limitation of PDT is the long incubation time required to allow penetration of the photosensitizer. OBJECTIVE The aim of this study was to assess if pretreatment with an ablative carbon dioxide (CO2) fractional laser can reduce the incubation time...

Treatment of vitiligo is challenging and requires a multidisciplinary approach. Fractional carbon dioxide (CO2) laser as an add-on to conventional treatment has been reported to be effective, but there is no consensus on its use. A systematic review was performed by searching major databases for relevant publications to February 2017. Six studies with 85 participants were included. For those wi...
