18 December 2022

The slimming and anti-dimpling effects of the products can be assessed in a relevant way through consumer tests.

They offer tailor-made protocols according to their clients’ objectives. A self-assessment by the volunteers can be coupled with a visual evaluation of the dimples by their study managers (specific scale with photos).

Hemi body studies may allow a comparative study of two formulas or two methods of application.

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

60 women participated in this study over 56 days.

An evaluation of the intensity of the dimples on each thigh was carried out by their researcher thanks to a visual scale at these three study times.

The application and the texture of the product is an important aspect for women (sticky, greasy, penetration and felt during massage, the product must blend into the skin).
The notion of perfume is not essential, but they expect a pleasant scent that they want to enjoy if possible.
The recommended 10-minute massage protocol, although restrictive, allows women to rediscover their skin and see it change more significantly as they go along.
Women are delighted to use a product with an accessory because they feel that it makes the circulation work more and the massage is more effective than with the hands.
The effectiveness of the slimming treatment on the anti-dimpling effect is significant over 56 days of study (more than 80% of favorable opinions), with or without accessory. The use of the accessory increased the effectiveness in self-assessment (+10%).
The accessory group noticed a significant result on firmness (89%) and smoother skin appearance (92%).
The accessory-free group rated immediate skin softness (88%) and over time (95%) as well as smoother skin (89%).
