Study Description

Brief Summary

STYLAGE® HydroMax is a CE-marketed hyaluronic acid gel intended to improve skin moisturization and elasticity through injection into the dermis of the face, neck, neckline area and back of the hand. In this study, 47 female healthy subjects between the ages of 35 and 65, who have signs of cutaneous dryness and lack of elasticity on the cheek and on the neckline area, who have given her informed consent and met all the eligibility criteria, will be enrolled. One month apart subjects will randomly receive 3 injections of product in one cheek and in one side of the neckline area. Subjects will come to a total of 8 visits over a period of 9 months. Variation of moisturization, elasticity and roughness of treated areas in comparison with non-treated areas will be measured using specific devices by independent evaluators. Global aesthetic improvement, subject satisfaction, pain at injection and safety will also be assessed.

Detailed Description

This is a prospective, single center, randomized, intra-individual study with blinded evaluators assessing the efficacy and safety of STYLAGE® HydroMax on skin moisturization and elasticity on the cheek and neckline area. Forty seven female subjects will be enrolled and will receive 3 injections of product one month apart on the cheek and neckline area in a randomized fashion with the contralateral non-treated cheek and neckline area. Injection will be performed into the mid to deep dermis of the cheek and neckline area (1 mL per session and per area) by micro-papular injection technique. Subjects will be followed up at 1, 2, 3, 4, 6 and 9 months timepoints. Variation of moisturization, elasticity and roughness of treated areas in comparison with non-treated areas will be measured using Corneometer®, Cutometer®, Dermatop® or Primos Lite® respectively. Global aesthetic improvement, subject satisfaction, pain at injection and safety will also be assessed.

Outcome Measures

Primary Outcome Measures

Variation of cheek cutaneous moisturization [Month 3]
Variation from baseline before treatment (D0) to 3 months after treatment initiation of the cutaneous moisturization on the cheek, in comparison with the non-treated cheek, by an independent evaluator using Corneometer®.

Secondary Outcome Measures

Variation of cheek cutaneous moisturization [Month 1, Month 2, Month 4, Month 6, Month 9]
Variation from baseline to 1, 2, 4, 6 and 9 months after treatment initiation of the cutaneous moisturization on the cheek in comparison with the non-treated cheek by a blinded independent evaluator using Corneometer®.
Variation of neckline area cutaneous moisturization [Month 1, Month 2, Month 3, Month 4, Month 6, Month 9]
Variation from baseline to 1, 2, 3, 4, 6 and 9 months after treatment initiation of the cutaneous moisturization on the neckline area in comparison with the non-treated neckline area by a blinded independent evaluator using Corneometer®.
Variation of cheek and neckline area cutaneous elasticity [Month 1, Month 2, Month 3, Month 4, Month 6, Month 9]
Variation from baseline to 1, 2, 3, 4, 6 and 9 months after treatment initiation of the cutaneous elasticity on the cheek and neckline area in comparison with the non-treated cheek and neckline area by a blinded independent evaluator using Cutometer®.
Variation of cheek cutaneous roughness [Month 1, Month 2, Month 3, Month 4, Month 6, Month 9]
Variation from baseline to 1, 2, 3, 4, 6 and 9 months after treatment initiation of the cutaneous roughness on the cheek in comparison with the non-treated cheek by a blinded independent evaluator using Dermatop®.
Variation of neckline area cutaneous roughness [Month 1, Month 2, Month 3, Month 4, Month 6, Month 9]
Variation from baseline to 1, 2, 3, 4, 6 and 9 months after treatment initiation of the cutaneous roughness on the neckline area in comparison with the non-treated neckline area by a blinded independent evaluator using Primos Lite®.
