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 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%).
