Abstract
The present invention concerns a method of demonstrating the draining activity of a cosmetic and/or dermocosmetic treatment, said method comprising: prior to the treatment, acquiring at least one first datum representative of the water content in the superficial dermis and/or in the epidermis, using an MRI imaging technique having high resolution; treating at least part of the body with the composition; after the treatment, acquiring at least one second datum representative of the water content in the superficial dermis and/or epidermis, using said MRI imaging technique; demonstrating any draining activity by comparing the first and second data.
Claims27
A method of demonstrating the draining activity of a cosmetic and/or a dermocosmetic treatment, said method comprising:
- prior to the treatment, acquiring at least one first datum representative of the water content in the superficial dermis and/or in the epidermis, using an MRI imaging technique having high spatial resolution;
- treating at least part of the body with the composition;
- after the treatment, acquiring at least one second datum representative of the water content in the superficial dermis and/or in the epidermis, using said MRI imaging technique;
- demonstrating any draining activity by comparing the first and second data.
A cosmetic composition, containing, in a cosmetically acceptable medium, at least one active ingredient, in particular a lipolytic active ingredient, said active ingredient being such that when it is present in a sufficient quantity in the composition, use of said active ingredient in particular by topical or general means can cause a reduction in N(H) of at least 2.5% in the superficial dermis and/or the epidermis.
A cosmetic composition, containing, in a cosmetically acceptable medium, at least one active ingredient, in particular a lipolytic active ingredient, said active ingredient being such that when it is present in a sufficient quantity in the composition, use of said active ingredient in particular by topical or general means can cause a reduction in T1 of at least 2.0% in the superficial dermis and/or the epidermis.
A cosmetic composition, containing, in a cosmetically acceptable medium, at least one active ingredient, in particular a lipolytic active ingredient, said active ingredient being such that when it is present in a sufficient quantity in the composition, use of said active ingredient in particular by topical or general means can cause a reduction in T2 of at least 1.5% in the epidermis.
The use of a lipolytic active ingredient for the production of a composition having a draining effect on the superficial dermis and/or the epidermis.
