简要总结
This single-center, split-body, double-blind, randomized, controlled clinical trial was conducted to assess the efficacy and tolerance of a topical firming body moisturizer when used over the course of 12 weeks by women with mild to moderate sagging, crepey skin, and overall photodamage on the upper arms. A total of 40 subjects completed study participation which included 10 subjects in the biopsy subgroup.
详细描述
This single-center, split-body, double-blind, randomized, controlled clinical trial is being conducted to assess the efficacy and tolerance of the topical firming body moisturizer when used over the course of 12 weeks by women with mild to moderate sagging, crepey skin, and overall photodamage on the upper arms.
Efficacy and tolerance will be assessed through clinical grading at baseline and weeks 4, 8, and 12. Efficacy will also be assessed through Corneometer and upper arm circumference measurements at baseline and weeks 4, 8, and 12, and Cutometer and Ultrasound measurements at baseline and weeks 8 and 12. Self-assessment questionnaires will be completed at baseline and week 12. Digital images will be taken at baseline and weeks 4, 8, and 12. Vectra H2 3D images will be taken at baseline and weeks 8 and 12. BMI will be measured at baseline and weeks 8 and 12. Biopsies will be collected from a subgroup of at least 10 subjects at baseline and week 12 (two biopsies on each arm at each time point; total of 8 per biopsy subject).
A total of 40 subjects completed study participation which included 10 subjects in the biopsy subgroup.

盲法说明
Prior to the start of the study, Stephens will generate 2 randomization lists (1 for biopsy subjects and 1 for non-biopsy subjects) to establish treatment assignment to 1 arm (left or right) with the other arm untreated (receiving a placebo). Each list will first be created by concatenating blocks of size of 4 subjects, 2 with left arm treated/right arm untreated and 2 with right arm treated/left arm untreated. The lists will then be randomized by variables from 2 independent uniform distributions: 1 to randomize subjects within block and 1 to randomize blocks. After the randomization lists are created, treatment arm will be assigned to each subject number accordingly.

结局指标
主要结局
Change from Baseline in Skin Crepiness Score
时间窗: 12 weeks
Investigator assessed the participants' skin crepiness using a 10-point scale where none 0 = skin appears smooth with no crinkling to severe 9 = prominent, extensive crinkly texture at baseline, week 4, 8, and 12. A decrease in score indicates improvement.
Change from Baseline in Evenness of Skin Tone Score
时间窗: 12 weeks
Investigator assessed the participants' evenness of skin tone using a 10-point scale where none 0 = even skin color, no observable hyperpigmentation to severe 9 = significant detectable hyperpigmentation appearance at baseline, week 8 and 12. A decrease in score indicates improvement.
Change from Baseline in Objective Erythema Parameters
时间窗: 12 weeks
Investigator assessed the participants' signs of erythema using a 4-point scale where none 0 = no erythema to severe 4 = marked redness at baseline and week 12. A decrease in score indicates improvement.
Change from Baseline in Objective Dryness Parameters
时间窗: 12 weeks
Investigator assessed the participants' signs of dryness using a 4-point scale where none 0 = no dryness to severe 4 = marked dryness at baseline and week 12. A decrease in score indicates improvement.
Change from Baseline in Skin Roughness (Tactile) Score
时间窗: 12 weeks
Investigator assessed the participants' skin roughness (tactile) using a 10-point scale where none 0 = no palpable skin roughness, drag or surface bumps to severe 9 = significantly palpable skin roughness, drag, and surface bumps at baseline, week 4, 8 and 12. A decrease in score indicates improvement.
Change from Baseline in Objective Peeling Parameters
时间窗: 12 weeks
Investigator assessed the participants' signs of peeling using a 4-point scale where none 0 = no peeling to severe 4 = marked peeling at baseline and week 12. A decrease in score indicates improvement.
Change from Baseline in Subjective Burning Parameters
时间窗: 12 weeks
Participants assessed signs of burning using a 4-point scale where none 0 = no burning to severe 4 = hot burning sensation at baseline and week 12. A decrease in score indicates improvement.
Change from Baseline in Skin Elasticity Score
时间窗: 12 weeks
Investigator assessed the participants' skin elasticity using a 10-point scale where none 0 = skin feels toned, dense and resilient to severe 9 = skin feels pliable, thin and nonresilient at baseline, week 8 and 12. A decrease in score indicates improvement.
