Description

Title of the invention: Anti-aging care kit for keratin materials

[0001] The present invention relates to a kit comprising four care compositions each comprising one or more specific active ingredients in specific proportions.

[0002] The present invention also relates to a method for caring for keratin materials comprising the application of the compositions of the kit according to the invention according to a specific sequence.

[0003] One of the current consumer trends is to want to look young for as long as possible. They therefore seek to reduce the signs of skin aging, for example wrinkles and fine lines, thinning of the epidermis and / or the appearance of loose and sagging skin, and / or seek to delay the phenomenon of skin aging. Many products designed to keep skin radiant and wrinkle-free for as long as possible, the signs of young skin, have therefore been developed. These products include one or more biological active ingredients that have demonstrated biological efficacy against skin aging.

[0004] However, the performance of these products is difficult for consumers to perceive because their effects are not visible quickly (often after a period of use exceeding three months).

[0005] There is therefore a need for products providing one or more anti-aging benefits more quickly than current products, in particular providing one or more anti-aging benefits after a period of use of less than three months.

[0006] In particular, there is a need for products providing a more uniform complexion, and / or reduced / tightened pores, and / or a fatigue-relieving effect, and / or reduced wrinkles and / or reduced fine lines and / or a plumper appearance of the skin and / or more supple skin more quickly than current products, in particular after a period of use of less than three months, preferably less than or equal to 1 month, preferably less than or equal to two weeks, preferably less than or equal to one week.

[0007] The inventors have now discovered that a kit comprising the combination of four compositions, each comprising one or more specific active ingredients in specific proportions, makes it possible to accelerate the appearance of anti-aging benefits, and therefore allows consumers to perceive the effects on their skin more quickly.

[0008] The inventors have also discovered that a process for caring for keratin materials comprising the application of these four compositions according to a specific sequence makes it possible to improve and accelerate the appearance of anti-aging benefits, and therefore allows consumers to perceive the effects on their skin more quickly.

[0009] Thus, the subject of the present invention is a kit, preferably for the care of keratin materials, comprising:

[0010] - a first composition comprising between 1 and 8% by weight, relative to the weight total of the first composition, an alpha-hydroxy acid, and optionally a beta-hydroxy acid,

[0011] - a second composition comprising between 2 and 15% by weight, relative to the total weight of the second composition, of ascorbic acid and / or one of its derivatives,

[0012] - a third composition comprising at least one UV filter, and

[0013] - a fourth composition comprising between 0.05% and 1% by weight, relative to the total weight of the fourth composition, of retinol and / or one of its derivatives,

[0014] wherein the first composition, the second composition, the third composition and the fourth composition are each placed separately from each other.

[0015] The first, second, third and fourth compositions according to the invention are preferably intended for topical application, in particular to keratin materials, in particular the skin. They comprise in particular a physiologically acceptable medium, that is to say a medium compatible with all keratin materials, in particular the skin.

[0016] For the purposes of the present invention, keratin materials mean skin. By "skin" is meant the skin of the face and / or body.

[0017] The present invention also relates to a cosmetic process for caring for keratin materials, preferably the skin, comprising:

[0018] - a first series of steps, comprising:

[0019] - a step a) of applying to said keratin materials a first composition position comprising between 1% and 8% by weight, relative to the total weight of the first composition, of an alpha-hydroxy acid, and optionally a beta hydroxy acid,

[0020] - a step b) of application to said keratin materials of a second com position comprising between 2% and 15% by weight, relative to the total weight of the second composition, of ascorbic acid and / or one of its derivatives,

[0021] - a step c) of applying to said keratin materials a third com position comprising at least one UV filter, and

[0022] - a second series of steps, comprising:

[0023] - a step a') of application to said keratin materials of the first composition position,

[0024] - a step b') of application to said keratin materials of the second com position, and

[0025] - a step c') of applying to said keratin materials a fourth com position comprising between 0.05 and 1% by weight, relative to the total weight of the fourth composition, of retinol and / or one of its derivatives.

[0026] The present invention further relates to the cosmetic use of a kit according to the invention for reducing the appearance and / or attenuating the signs of aging of keratin materials, in particular of the skin.
