Description

in food.

  Cosmetic composition for toning the bust Wile relates to the field of cosmetics and more particularly to compositions intended for the vein of the bust in women. Wile relates to new cosmetic compositions intended to be applied to the skin directly, or indirectly by means of a means of application impregnated with this composition and fixed on an element of women's clothing. The cosmetic composition comprises several plant extracts with an estrogen-like action, and a plant extract stimulating breast cells. The composition is preferably used for

veins of bodily beauty.

  In the state of the art, we know from the teaching of document FRA-2,780,885, pieces of adhesive tissue provided with an adhesive means for being retained on an element of the covering. This element relates to textile articles, and in particular lingerie or hosiery articles. These elements are coated with a composition based on a plant extract with estrogen-like action and an extract of the Kigelia africana plant, both being present in the form of a high composition. Adhesive tissue pieces of the prior art pose a problem because they must imperatively be detached from the textile article to allow cleaning of this textile article as often as is desirable. In fact, the pieces of adhesive tissue are simply impregnated directly with the viscous composition comprising the active ingredients. The adhesion between the viscous composition and the fabric does not hold

  that the viscous composition becomes sticky.

  But during the cleaning processes, the fabric is placed in water, and then the viscous composition dilutes and becomes more and more fluid, which contributes to its detachment from the support fabric. It is therefore imperative to unhook these coated pieces of fabric before cleaning, and to

fix them entirely.

  The object of the invention is to solve this problem by proposing a piece of fabric in which the active principle of the cosmetic composition is present inside the capsules grafted onto the piece of fabric, which makes it possible to leave the pieces of tissue fixed on the garment even during

of its cleaning.

  Indeed, it is preferably chosen to present the active principle in the form of an emulsion, or in the form of a liposoluble solution. The emulsion is preferably of the water in oil type. Thus the active principle is included in naturally occurring microspheres, so that walls of these microspheres are formed from lipid compounds. The lipid compounds chosen are preferably isohexadecane and or

PEG30 dipolyhydroxystearate.

  In the case where the active principle is preferably encapsulated, an encapsulation wall is for example obtained from polyurea. Wile has a particular affinity with the means of application, support, on which it is retained, this support correspond to the piece of fabric presented on the element of clothing. Su pport is in preferred real isation modes

  from fibers, or in the form of cellulosic pads.

  The support of the invention does not require an adhesive strip, it can be slid directly into an interior pocket already formed in the covering element, and be left there even when the latter is subjected to devastation. The capsules being hydrophobic, they do not release the active ingredient into the water. And the capsules themselves remain fixed in the support because the lipids of the wall have terminations allowing good

  grips on the fibers or cellulose of the support.

  Finally, the active ingredient included in these capsules preferably comprises an extract of clover, having a high level of isoflavones, and an extract of Yam, which is a precursor of DHEA. This association stimulates breast tissue, and makes it possible to obtain a rejuvenation of the bust, resulting in an increase in cellular tone. Indeed, we observe a growth of the synthesis of collagen of 67% and a growth of the synthesis of elastin of the order of 68%. In a preferred embodiment, the composition also comprises extracts of Nigella, fenugreek, and hops, which exhibit stimulating functions of lactation, and therefore mammary cells. This composition provides support and volume to breast glance, stimulating the surface tension of the skin and

increasing breast volume.

  This composition can be used for topical application

  direct, without having to be previously encapsulated.

  Following practical clinical examinations on volunteers, the composition of the invention provides improvements in firmness of the bust, skin firmness and skin elasticity. An improvement of the order of 14% of the projected distance between nipple and abdomen is obtained. In parallel, we get an improvement of more than 70% of the length of the breast fold. In addition, the curve of the breast is improved with an observed increase of 13% in the angle of opening of the breast, which

  corresponds to a straightening of the breast, and a decrease in ptosis.

  The angle of opening of the breast corresponds to a determined angle between two segments, the first segment connecting the end of the nipple to the abdomen, and

  the second segment connecting this same end of the nipple to the bust.

  This angle is all the more important as the breast is raised.

  An application of this cosmetic composition is especially recommended after childbirth, after a weight-loss treatment, or at

during menopause.
