Skin measurement solutions Firmness

Skin measurement solutions: FirmnessThe Dynaskin is an add-on to thedermaTOP system to provide firmessevaluation with a complete non contactmethod. It produce a deformation close tothe clinical approach by blowing airperpendicular to he area of interest orwith a dedicated angle of 45°. The systemcan measure in any position. The 3Dsensor using fringe projection techniquecapture before deformation the shape ofthe local surface, then when thedeformation is applied, and just after it.Performances:Equipement: Blowing head with controlsystem for non contact deformationSoftware: Acquisition/Processing of raw data/extration and calculation of parametersAcquisition: In Vivo / Automatic / 3sec.Measurement locations: face and bodyRepetitivity Reproducibility (R&R): 2.40%(time/location effect - no user effect)Validation: Product effect/correlation with age2:Dynaskin in situation1:Dynaskin mounted onthe dermaTOP sensorand control unitDevelopped incollaboration withOrion-ConceptA dedicated software module computeautomatically the difference betweenbefore and during the deformationproviding the absolute deformation of theskin and sub-jacent tissues. Using theperpendicular air beam, the purecompression contribution of the skin andtissue are measured (firmness) while usingthe 45° angle introduce the slidingcontribution effect on the tissues as well(mobility laxity). The air pressure can beset accordingly to obtain the desiredeformation on different part of the body3: dynaskin principle with90° and 45° anglewww.eotech.fr

Applications:The Dynaskin is suitable to measure firmnesschange before and after treatment under veryreproducable conditions. These conditions arepressure, area of interesta nd sensor oriantationto have an air beam perpendicualr to thesurface.Because of the dermaTOP coupling, the systemcan measure anywhere on the body using theViso-3D for the face and cellulite, tripods forany other part.In its principal, this technique gives visual andquantitative, approach similar to real tactileperception of firmness and laxity of the skin andits sag. This system has been validated andcompared to other reference techniques forboth product efficacy evaluationand for studying skin typologies changes versusage.Young subjectAlignment andpositionningdeformation and acquisistion3D results of the deformationSPECIFICATIONS:Dimensions:Weigthangles: 90°, -45°, 45°Air pressure range: 0.05 to 0.5NAir pressure requirements: 4 bars minComputed values:- Max heigth, mean heigth, volume, area andcircumference of the deformation- Deformation anisotropySections trougth the deformationExpected parameters :- Tension, Firmness, Laxity / Plasticity-Isotropy of skin mechanical characteristics(Forthcoming)Measured zones :- Face : sides, eye bags, front, chin, neck- Body: all locations (Leg, knee, belly, abdomen,haunch, back, arm…etc.Product claims :- Firmness, Restructuring (Anti-ageing, body care,fitness, draining, tonic, oval of face, lifting…)- Tension effect (Anti-ageing, anti-wrinkles,lightening…)Old subjectdeformation analysis:volume, depth, areaEOTECH SAissue 2009
