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.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Age-related changes in fine lines on the cheek
Periodo de tiempo: 4 Months

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
Periodo de tiempo: 4 Months
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
Periodo de tiempo: 4 Months
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
Periodo de tiempo: 4 Months
Transepidermal water loss measurement using an AquaFlux AF100 (Biox Systems Ltd)
4 Months
Age-related changes in skin radiance on the cheek
Periodo de tiempo: 4 Months
Measurement of light reflection using a Skin-Glossymeter GL200 (Courage & Khazaka)
4 Months
Age-related changes in skin color on the cheek
Periodo de tiempo: 4 Months
Skin colorimetric measurement using a Spectrophotometer (Konica Minolta)
4 Months
Age-related changes in skin melanin on the cheek
Periodo de tiempo: 4 Months
Colorimetric measurement of skin melanin using a Mexameter MX18 (Courage & Khazaka)
4 Months
