Clinical Trial Summary

The goal of this clinical trial is to compare the 2 different prototype of cytoselectivecryotherapy 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 2 prototypes of cyto-selective cryotherapy treatments - the performance of 2 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.

Intervention

Device:
CRYONOVE (EC14_4osc)
The prototype is a variant version from that of a CE marked MD already commercialized (Cryobeauty mains, Cryobeauty Pharma SAS, France) which produces a cryogenic spray sequence (EC14). The prototype is intended to treat pigmented spots of the face (PIH spots and senile and solar lentigos).
CRYONOVE (EC05osc)

Outcome

Type Measure Description Time frame Safety issue
Primary Tolerance Evaluate the evolution of the scores given by the dermatologist or the participant on the following items :
Hyperpigmentation (IGA scale)* Hypopigmentation Erythema, oedema, micro-bruise, hematoma, dryness, desquamation, fissures / cracks, roughness, crust Skin sensation (tightness, stinging, itching, warm and burning sensations) Day 0: Pain after each treatment (5 min. rest between two treatments) Other unexpected events
*: IGA Scale : Investigator's Global Assessment - Scale in 6 points (0 to 5) 0 = clear of hyperpigmentation
= almost clear of hyperpigmentation
= mild, but noticeable hyperpigmentation
= moderate hyperpigmentation (medium brown in quality)
= severe hyperpigmentation (dark brown in quality)
= very severe hyperpigmentation (very dark brown, almost black in quality)
[Time Frame: Day 7, Day 14, Day 21, Day 28, Day 35, Day 42, Day 56, Day 70]
Secondary Performance (Acquisitions C-cube) --> Performance assesment :
• Standardized photographs will be taken before the treatment at each visit (C-Cube acquisition without analysis) - illustration only
[Time Frame: Day 7, Day 14, Day 21, Day 28, Day 35, Day 42, Day 56, Day 70]
