Outcomes
Primary outcome [1] 320584 0
Standardized cellulite photographs and scoring
The participant will put on a thong supplied for the measurement process. The participant will then stand with feet placed on a marked position on the floor. A standardised series of photographs will be taken using a digital SLR camera and light source placed on a tripod at a predetermined height and distance from the treatment site. Images will be coded and stored for later data analysis. Images will be analysed by visual grading by three blinded, independent assessors, who will grade the cellulite based on an established Cellulite Severity Scale. The assessors will be trained using a set of standardised images and their reliability will be assessed by repeat measurement at a 4 week interval. We will train 4 assessors and select the three most reliable for the research study.
Timepoint [1] 320584 0
1. Final assessment will be 12 weeks post first treatment
2. Assessment every 4 weeks post first treatment
Primary outcome [2] 321420 0
Questionnaire
On week 4, 8 and 12 the participant will complete a questionnaire to assess their perception of the cream products in terms of their effects on their skin.
At week 12, participants will also be asked for the overall perception of the cream products in terms of their effects on their skin.
The questionnaire was designed specifically for this trial and was validated by sending to independent researchers for feedback

Assessment at 4, 8 and 12 weeks post first treatment
Primary outcome [3] 321421 0
Cutaneous-fold thickness
The skin fold thickness will be measured at a mid-way point within the treatment site. Each skin-fold measurement will be taken by gripping the skin with the thumb and index finger, 1 cm away from the measurement point, then measuring the skin fold thickness with a plicometer. Triplicate measurements will be conducted by a same blinded assessor.

Assessment at 4, 8 and 12 weeks post first treatment
Secondary outcome [1] 372110 0
Thigh circumference
The thigh circumference will be measured at a distance (150 mm proximal to the patella), which will be a mid-way point in the treatment site, using a cloth measuring tape. Triplicate measurements will be conducted by an assessor (TP).
