Filter by:Pierre Fabre Dermo-Cosmétique has commercialized a cosmetic product (D-pigment rich texture) for treatment of hyperpigmentation. The aim of this study is to evaluate the efficacy of D-pigment after laser therapy, through its action on peri-lesional areas, in obtaining better cosmetic effect.
This study evaluates the performance of new technology "CRYOTHERAPY MAINS ET DECOLLETE" against a classic cryotherapy "Nitrogen Liquid " to treat solar lentigines. The hands and the neckline will be randomised, either left or right side and treated by two cryotherapy devices: 1. CRYOTHERAPY MAINS ET DECOLLETE is the device under evaluation. 2. Liquid nitrogen is a comparator device.
This study evaluates the performance of "CRYOBEAUTY MAINS", a Cyto-selective Cryotherapy based on Difluoroethane as a treatment of Solar Lentigines in 30 volunteers. Only one application of "CRYOBEAUTY MAINS" in one hand (right or left hand according to the randomization code).
The purpose of this study is to evaluate the effectiveness and safety of two laser systems for improvement of lentigines on the hands.
Non-invasive lentigo maligna (LM) is characterized by an in situ proliferation of melanoma cells, limited to the epidermis. It is found most commonly on the head and neck of elderly persons, with a peak incidence in the seventh or eighth decade. If untreated, it may develop into invasive melanoma. The gold standard treatment for LM is surgery using a 5-10 mm margin. However, the lesions can be large, and conventional surgery can be difficult, particularly on the face. Then, there is a need for a topical non-surgical treatment of LM. Ingenol mebutate (IM)/Picato® is able to induce cell apoptosis and an inflammatory reaction in the epidermis and superficial dermis. Thus, the investigators hypothesize that the topical use of Picato® could induce the cure or a prolonged remission of non-invasive LM. Because of the exploratory phase of this study (no case report and no clinical trial at the early phase of designing this study, only one case report at the time of submission of this form) the investigators will conduct an open label study limited to patients who are not eligible to, or who refuse surgical treatment of their LM. The main objective of this study is to determine the proportion of patients with complete response (CR) obtained 2 months after one or two cycles (for patients who did not respond to the first cycle) of topical treatment by IM 150 µg/g for non-invasive LM of the face (head and neck).
This study investigates the efficacy of photodynamic therapy (PDT) in the treatment of lentigo maligna (LM). Hyperspectral imaging system (HIS) will be used to determine the margins of LM and to rule out possible invasion. Participants will receive photodynamic therapy three times consecutively with intervals of two weeks using 5-aminolevulinic acid nanoemulsion (BF-200 ALA, Ameluz®) as a light sensitizing cream. Four weeks after last photodynamic therapy the lentigo maligna lesion will be excised surgically from the skin. Result of the treatment is assessed with histopathological examination and immunohistochemical staining of removed tissue specimen.
To investigate the benefit of the application of topical high potency steroid on the incidence of post inflammatory hyperpigmentation after laser treatment.
The purpose of this investigation is to evaluate safety and efficacy of the Cutera enlighten dual-pulse duration, dual-wavelength 532nm KTP/1064nm Nd:YAG laser for the treatment of melasma and lentigines on the face in Asian skin.
Benign pigmented lesions as solar lentigines are a common finding in Caucasian individuals. Their removal may be requested for aesthetic reasons. The goal of the study is comparing the efficacy and tolerance of two different therapy modalities established for treating solar lentigines. The right back of the hand side will be treated with the Q-switched SINON Rubin 694nm Laser, the left back of the hand side with a hydrochinon containing bleaching cream (Pigmanorm® cream). The investigators estimate that a physical therapy with a Q-switched Rubin laser system is more effective in the removal of solar lentigines than a topical chemical therapy with a hydrochinon containing bleaching cream.
The purpose of this study is to evaluate the effects of the Revlite Laser System for treatment of facial solar lentigines
