19/07/2022 - Evaluating the effectiveness of slimming products through consumer tests

Assessing the effectiveness of slimming products through consumer testing

The slimming and anti-cellulite effects of the products can be assessed in a relevant way thanks to consumer tests.

We offer tailor-made protocols according to the objectives of our clients.

A self-assessment by the volunteers can be coupled with a visual assessment of the capitons by our study managers (specific scale with photos).

Studies in hemibody can allow a comparative study of two formulas or two methods of application.

Here is the protocol of a study we recently carried out on a slimming treatment.

60 women participated in this study over 56 days.

Features of the panel: 

  • All volunteers with BMI between 22 and 25.
  • Volunteers aged 20 to 60
  • Regular users of products of this type
  • Women prone to cellulite and cellulite problems and looking for an anti-cellulite/slimming result.

The volunteers used a slimming treatment according to an explained massage protocol, for 56 days, morning and evening, with and without a half-body accessory (right/left randomization).

The volunteers came to the center at T0, T28 and T56 days.

  • An evaluation of the intensity of the dimples on each thigh was carried out by our research manager using a visual scale at these three study times.
  • Photos were taken of the same area at the three study times.
  • An evaluation of the intensity of pinching pain on each thigh was carried out by self-evaluation by the volunteers at the three study times.
  • Self-assessment questionnaires were completed at the three study times by the volunteers.

The main results of the study showed that:

  • The application of the product is an important aspect for women (sticky, greasy, penetration and felt on massage, the product must blend into the skin).
  • The notion of perfume is not essential but they expect a pleasant scent which they want to enjoy as long as possible.
  • The recommended 10-minute massage protocol, although restrictive, allows women to rediscover their skin and see it change more significantly over time.
  • Women are happy to use a product with an attachment because they feel it works the circulation more and the massage is more effective than with the hands.
  • The effectiveness of the slimming treatment on the anti-cellulite effect is significant over 56 days of study (more than 80% favorable opinions), with or without accessories. The use of the accessory reinforced the efficiency in self-assessment (+10%).
  • The group with accessories noticed a significant result on firmness (89%) and smoother appearance of the skin (92%).
  • The no-accessory group rated skin smooth immediately (88%) and over time (95%) as well as smoother skin (89%).
