Description

Inclusion Criteria:

• Caucasian subjects with Fitzpatrick skin type II or III.
• Subject agreeing to complete all study required procedures.
• Subject having given freely and expressly her informed consent.

Exclusion Criteria:

• Pregnant or nursing woman or planning a pregnancy during the study.
• Subject who had been deprived of their freedom by administrative or legal decision or who is under guardianship.
• Subject in a social or sanitary establishment.
• Subject participating to another research on human beings or being in an exclusion period for a previous study.
• Subject who underwent tissue augmentation with dermal fillers including HA, calcium hydroxylapatite, autologous fat, mesotherapy, or other cosmetic procedures (eg, face-lift, laser, photomodulation, intense pulsed light, radiofrequency, dermabrasion, chemical peel, liposuction of the thigh, or other ablative procedures) in the face or thigh within 12 months before study entry or was planning to undergo any such treatment during the study.
• Subject who underwent treatment with botulinum toxins in the face or neck within 6 months of study entry or was planning to undergo such treatment during the study.
• Subject who ever received semi-permanent fillers or permanent facial implants (eg, poly-L-lactic acid, polymethylmethacrylate, silicone, expanded polytetrafluoroethylene) anywhere in the face or thigh, or was planning to be implanted with any of these products at any time during the study.
• Subject with current cutaneous inflammatory or infectious processes (eg, acne, herpes), abscess, an unhealed wound, or a cancerous or precancerous lesion on the face or thigh that could interfere with measurements.
• Subject having changed, started or stopped any hormonal treatment or any treatment likely to have an impact on skin condition (over-the-counter or prescription, oral or topical, or anti-wrinkle products on the face), within 30 days prior to enrollment or is planning to begin using such products during the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Age-related changes in fine lines on the cheek	Measured using a 5 point photonumeric scale (Allergan Fine Lines scale) The scale range is 0 to 4, with 0 indicating no fine lines and 4 being the most severe fine lines (greater than 5 superficial lines with crosshatching).	4 Months
Age-related changes in skin hydration on the cheek	Tissue dielectric constant measurement using MoistureMeter D (Delfin Technologies). Tissue dielectric constant is expressed as a unitless value that is directly proportional to the amount of water in the tissue.	4 Months
Age-related changes in skin hydration on the cheek	Tissue dielectric constant measurement using a Corneometer (Courage & Khazaka). Tissue dielectric constant is expressed as a unitless value that is directly proportional to the amount of water in the tissue.	4 Months
Age-related changes in skin barrier function on the cheek	Transepidermal water loss measurement using an AquaFlux AF100 (Biox Systems Ltd)	4 Months
Age-related changes in skin radiance on the cheek	Measurement of light reflection using a Skin-Glossymeter GL200 (Courage & Khazaka)	4 Months
Age-related changes in skin color on the cheek	Skin colorimetric measurement using a Spectrophotometer (Konica Minolta)	4 Months
Age-related changes in skin melanin on the cheek	Colorimetric measurement of skin melanin using a Mexameter MX18 (Courage & Khazaka)	4 Months
Age-related changes in skin elasticity on the cheek and thigh	Skin elasticity measurement using a Cutometer (Courage & Khazaka), ElastiMeter (Delfin Technologies), and Dermal Torque Meter (Dia-Stron Limited)	4 Months
Age-related changes in skin thickness on the cheek and thigh	Ultrasound imaging using a Dermascan Ultrasound (Cortex Technology)	4 Months
Age-related changes in skin topography on the cheek and thigh	Skin topography imaged using a PRIMOS (Canfield Scientific) fringe projection imaging system. Output measurements from the images will include Ra (average roughness), Rz (average height of roughness), and Rt (maximum height of the roughness profile).	4 Months
Age-related changes in skin topography on the cheek and thigh	Skin topography imaged using a DermaTOP (EOTECH) fringe projection imaging system. Output measurements from the images will include Ra (average roughness), Rz (average height of roughness), and Rt (maximum height of the roughness profile).	4 Months
Age-related changes in skin density on the cheek and thigh	Ultrasound imaging using a Dermascan Ultrasound (Cortex Technology)	4 Months
