NCT06288607
This trial is a single-center, prospective study. The study proposes to recruit 20 patients with solar lentigo on both sides of the face. Patients are to be treated with high-intensity focused ultrasound (MFUS One, Hunan Peninsula Medical Technology Co., Ltd., China). oth sides of the face received treatment with identical parameters. The facial images are collected with dermoscope (DermLite DL4,3 Gen Inc., San Juan Capistrano, CA, USA), VISIA® (Canfield Company, USA) and a two-photon microscope (Transcend Vivoscope, China). For dermoscopy images, ImageJ software was then utilized to perform Lab\* conversion on both the lesional area and the surrounding non-lesional areas. Measurements of transepidermal water loss (TEWL) values, skin elasticity and related images at the same location, along with adverse events, physician and subjective global aesthetic improvement scale scores are recorded before and at week2, week 4, week6 and week8.

Broadband light treatment for Solar Lentigines
NCT06305897
The goal of this clinical trial is to compare the 3 different prototype of cyto-selective cryotherapy devices (name of the devices : CRYONOVE) use in brown spots on the face of subject from different ethnicities. The main questions it aims to answer are: * the tolerance of 3 prototypes of cyto-selective cryotherapy treatments * the performance of 3 prototypes of cyto-selective cryotherapy treatments Participants will be treated for each spots with a definied prototype during 6 treatment visits. Researchers will compare the tolerance and performance of the 3 prototypes.
NCT05625815
CS5\_3 aims to evaluate the tolerance and to adjust the mode of administration of 4 different conditions of cryotherapy treatments applied on the brown spots of the face and hands with 3 prototypes. A brown spot is defined as solar or senile lentigo and post-inflammatory hyperpigmentation (PIH). Each treatment corresponds to a combination of a specific sequence of a cryogenic spray and of a frequency of application. The study will evaluate 3 prototypes : * Prototype 1 : SN from (816-v1 001) to (816-v1 100) * Prototype 2 : SN from (816-v1 101) to (816-v1 150) * Prototype 3 : SN from (816-v1 151) to (816-v1 200) Prototypes will be applied on the face and hands according to specific frequencies of application.
NCT05886010
CS5\_4 study aim to evaluate the performance and the tolerance of 3 prototypes of cyto-selective cryotherapy treatments applied on the brown spots on the face and hands of asian ethnicity skins (chinese). A brown spot is defined as solar or senile lentigo (SSL) and post-inflammatory hyperpigmentation (PIH). Each treatment corresponds to a combination of a specific sequence of cryogenic spray and of a frequency of application. Each spot will be treated by a defined prototype (always the same device on the same spot all along the study). The study will evaluate the following prototype : * Prototypes 1 * Prototypes 2 * Prototypes 3
NCT05883657
CS5\_7 study aim to evaluate the tolerance and to adjust the mode of administration of two conditions of cryotherapy treatment applied on the brown spots of the face and hands with 1 prototype (816-v1). A brown spot is defined as solar or senile lentigo and post-inflammatory hyperpigmentation (PIH). The study will evaluate the following prototype : • Prototypes from (816-v1 201) to (816-v1 290)
NCT05322668
Cryotherapy is more and more used to improve skin appearance. Devices using difluoroethane, manufactured by CRYONOVE PHARMA, are already available on the local and international markets, e.g. CRYOBEAUTY MAINS and CRYOBEAUTY CORPS. However, the cryogenic gas (conventional cryotherapy - liquid nitrogen) creates a dermabrasion of the skin surface and person receiving this kind of treatment presents an impaired skin during a few days following the treatment as temporary damage of stratum corneum, erythema, scars, burns. Following the side effects occurring after conventional cryotherapy application, it seems interesting for the sponsor to select other sequences of a cryogenic spray (4 prototypes of devices) which could be used for lentigo treatment with a same benefit for the consumers without any safety outcomes. This study will assess the use of different prototypes with a sequence of application of cryogenic gas which reaches a higher temperature than those which used with the reference device, in order to increase the acceptability of the device. (CS4\_3) proof of concept, interventional, monocentric, aims to evaluate the tolerance of cryotherapy treatments applied on healthy skin on the back of the hands. The main objective of the study is to evaluate on phototype V and VI, the tolerance of 4 different conditions of cryotherapy treatments (4 prototypes) applied on healthy skin on the back of the hands.
NCT03225729
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.
NCT03157427
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).
