Description

The subject of the present invention is a makeup or care kit for

  keratin materials, especially skin and lips, consisting of at least two compositions intended to be applied to one another, each composition comprising at least one hydrating polyol.

  The invention also relates to a cosmetic process for the make-up and / or care of keratin materials, in particular the skin and the lips, comprising the application of the compositions to the skin and to its use for makeup or care.

  Makeup compositions, especially foundation, are used to mask the defects of relief and color of the skin. To do this, they contain a powdery phase consisting of pigments and fillers. The higher the content of pigments and fillers in the composition, the better the camouflage of the color defects of the skin. However, an excessive content of pigments and fillers causes a marking of the defects of relief of the skin.

  When the keratin materials are dehydrated, their surface has irregularities the skin may for example be scaly or peel, or the lips may chapped which does not allow a continuous and homogeneous deposition of makeup. In particular, the color and shine of the makeup may vary on the makeup surface; these variations do not correspond to the wish of the user who seeks instead to obtain a uniform makeup, with the least possible irregularities.

  In addition, when the makeup composition comprises a pulverulent phase, its application to the skin and / or the lips, often leads to drying of the keratin materials, which causes the user a feeling of tightness and discomfort.

  It is therefore necessary, in order to obtain satisfactory makeup, that the keratin materials are sufficiently hydrated.

  It is known to introduce, in the cosmetic compositions, moisturizing agents to reduce the sensation of drying. However, the presence of certain moisturizing agents such as glycerol confers a sticky effect on makeup, which is detrimental to a good spread of makeup. The latter therefore has altered cosmetic properties, in particular, the deposit formed on keratin materials is not uniform.

  There is therefore a need for a makeup product to achieve uniform makeup, while giving the user a feeling of comfort and hydration.

  The inventors have demonstrated that by introducing, in a make-up or skincare kit, two compositions each containing a high content of moisturizing agent, it was possible to obtain a makeup imparting a feeling of hydration to the skin. user without giving a sticky effect to makeup.

  The subject of the present invention is, according to a first aspect, a kit for makeup and / or care of keratin materials, in particular skin and lips, comprising a first and a second cosmetic composition, each composition comprising an aqueous phase containing at least one less a hydrating polyol present in a content less than or equal to 15% by weight relative to the total weight of each composition, the sum of the polyol contents of the first and second compositions, expressed by weight relative to the total weight of each composition, being greater than or equal to 8.
