Arm && Interventions

Group	Intervention	Description
Juvéderm® VOLITE	Juvederm® VOLITE	Participants received Juvéderm® VOLITE, intradermal injection on a zone of 8 centimeter (cm) x 4 cm (32 cm\^2) of the volar left forearm on Day 0. The dose to be injected was decided by the investigator as per the Directions for Use. A maximum of 1 milliliter (mL) was injected on the zone treated.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Skin Hydration as Measured by MoistureMeterD® 0.5 mm	Baseline [Day 0 (D0)] to Days 28 (D28) and 84 (D84)	Skin hydration was measured using MoistureMeterD® XS (for epidermis and dermis), a non-invasive probe which measures the dielectric constant of the skin at a depth of 0.5 mm. 5 measurements were done on the same zone and the average value was calculated, expressed as tissue dielectric constant (TDC). The TDC is directly proportional to the amount of water in the tissue. A positive change from Baseline indicates better skin hydration. Values were obtained from a mixed analysis of variance (ANOVA) model. The data is presented for area treated with Juvéderm® VOLITE and non-treated area in the same participants.

The TDC is directly proportional to the amount of water in the tissue. A positive change from Baseline indicates better skin hydration. Values were obtained from a mixed ANOVA model. The data is presented for area treated with Juvéderm® VOLITE and non-treated area in the same participants.
Change From Baseline in Relative Parameters of Skin Elasticity: Q1, Q2, Q3 as Measured by Cutometer ®	Baseline (D0) to D28 and D84	The parameters evaluated were: Elastic Recovery (Q1)=elastic recovery area (QE)/maximum recovery area (QO), Viscous Recovery (Q2)=viscous recovery area (QR)/maximum recovery area (QO) and Viscoelastic Recovery (Q3)= (QE+QR)/QO. 2 measurements were done on the same zone and the average value was calculated. Values were obtained from a mixed ANOVA model. A negative change from Baseline in Q1 and Q2 indicates decreased skin elasticity. A positive change from Baseline in Q3 indicates decreased skin elasticity. The data is presented for area treated with Juvéderm® VOLITE and non-treated area in the same participants.
Number of Participants With at Least One Treatment-emergent Adverse Event (AE)	First dose of study treatment to end of the study (Up to 9 months)	An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A treatment-emergent AE is an AE that occurs or worsens after a participant receives study drug.
Change From Baseline in Skin Elasticity Parameters: Uf: Final Deformation (Firmness), Ue: Immediate Extensibility, Ur: Immediate Retraction (Tonicity), Ua: Total Recovery of the Initial State as Measured by Cutometer ®	Baseline (D0) to D28 and D84	Skin elasticity was measured by a Cutometer ® which uses an in vivo non-invasive method to evaluate biological extensibility and elasticity variations. The various parameters analysed were Uf: final deformation (firmness), Ue: immediate extensibility, Ur: immediate retraction (tonicity), Ua: total recovery of the initial state. 2 measurements were done on the same zone and the average value was calculated. Values were obtained from a mixed ANOVA model. A Negative change from Baseline indicates firmer skin. The data is presented for area treated with Juvéderm® VOLITE and non-treated area in the same participants.
Change From Baseline in Skin Hydration as Measured by Corneometer®	Baseline (D0) to D28 and D84	Corneometer® measures the hydration level of the superficial skin surface (epidermis). The measurement is based on capacitance measurement of a dielectric medium in this case skin. It uses fringing field capacitance sensors to measure the dielectric constant of the skin. The dielectric constant of skin will change with water content. This allows for any changes in skin hydration to be measured by the precision measuring capacitor. These changes in water content of the stratum corneum are converted into arbitrary units of hydration. 5 measurements were done on the same zone and average value was calculated. Values were obtained from a mixed ANOVA model and expressed in arbitrary units. A positive change from Baseline indicates better skin hydration rate. The data is presented for area treated with Juvéderm® VOLITE and non-treated area in the same participants.
