Definitions
- the present invention relates to a cosmetic or dermatological composition
- a cosmetic or dermatological composition comprising a combination of IGFl and / or a mimetic compound of IGFI and at least one isoflavonoid, as well as to the use of this composition, in particular for preventing or treating signs of physiological or photo-induced skin aging.
- This composition is preferably intended to improve the cutaneous signs of aging and / or photoaging by promoting the physiological proliferation of eratinocytes and / or by reducing epidermal differentiation.
- various endogenous or exogenous factors intervene in the appearance of wrinkles and / or fine lines, in the yellowing of the skin which develops a parchment appearance accompanied by the appearance of pigment spots, in the disorganization of the fibers.
- elastin and collagen resulting in a loss of elasticity, and in the loss of suppleness and / or firmness of the skin.
- Some of these signs of aging are more particularly linked to chronological or physiological aging, that is to say to "normal” aging linked to age or chronobiological, while others are more specific to induced aging, c that is to say aging generally caused by the environment; this is more particularly photoaging due to exposure to the sun.
- the skin changes due to chronological aging are the consequence of genetically programmed senescence in which endogenous factors intervene.
- This chronological aging causes, in particular, a slowing down of the renewal of the skin cells, which essentially results in the appearance of clinical alterations such as the appearance of fine wrinkles or fine lines, and in histopathological changes such as an increase the number and thickness of elastic fibers, loss of vertical fibers from the elastic tissue membrane, and the presence of large irregular fibroblasts in the cells of this elastic tissue.
- induced aging leads to clinical alterations such as thick wrinkles and the formation of soft, tanned skin, and histopathological changes such as excessive accumulation of elastic material in the upper dermis and degeneration of collagen fibers.
- the skin undergoes constant remodeling during aging and / or photoaging.
- Some of these transformations observed over time are notably the result of a modification of the body's natural secretion in hormones (growth hormones, prolactin, estrogen, etc.) and in growth factors (TGF ⁇ and ⁇ , EGF , IGF ).
- TGF ⁇ and ⁇ , EGF , IGF growth factors
- the role of these hormones and / or these growth factors is all the more important as we know that with aging, their release and their impact on the target tissues decrease.
- tissue growth stabilizes, while increased matrix degradation, which increases with age, is no longer offset by the regenerative action of these hormonal and / or growth factors.
- IGFs Insulin Growth Factors
- GH Growth Hormone
- the liver is the most important site for producing IGFs, but many cells are capable of producing IGFs.
- IGF1 and IGF2. Two types are classically described: IGF1 and IGF2. These are two peptides whose amino acid sequence partially resembles that of insulin, hence their name.
- the IGFI receptor has a shared affinity for insulin. This is not the case for the TIGF2 receptor.
- the object of the present invention is to propose a solution to these various problems, and in particular to propose new compositions capable of being used in cosmetics or in dermatology, in order to limit the aging of the skin, whether chronobiological or photo-induced. , and in particular the aging generated by the slowing down of cell renewal, the histopathological changes mentioned above, and the clinical alterations linked to induced aging.
- IGFI mimics with an isoflavonoid. It has indeed been found that this association makes it possible to limit the cutaneous signs of aging and / or photoaging by promoting the physiological proliferation of keratinocytes and / or by reducing epidermal differentiation.
- mimics of IGFI is meant in the present application, any substance promoting the release and / or synthesis of IGFl or any substance and / or extract of origin vegetable or bacterial selectively binding to the IGF1 IGF receptor and mimicking its skin effects.
- IGFI IGFI alone stimulates the proliferation of keratinocytes (Neely EK - Insulin-like growth factors are mitogenic for human keratinocytes and a squamous cell carcimona - J Invest Dermatol 1991 Jan; 96 (1) : 104-10). With regard to fibroplasts, it is also known that IGFI stimulates the synthesis of GAGs, and in particular the synthesis of collagen.
- the present invention therefore relates to a new cosmetic composition comprising, in a physiologically acceptable medium, an association between: a) IGFI and / or a compound and / or an extract of plant or bacterial origin mimicking IGFI , and b) at least one isoflavonoid, of natural or synthetic origin.
- Isoflavonoids are a subclass of flavonoids, formed of a 3-phenyl chroman skeleton which can have various substituents and different levels of oxidation. Unlike flavonoids, they are only found in a very limited number of plants.
- isoflavonoid groups together several classes of compounds among which mention may be made of isoflavones, isoflavanones, rotenoids, pterocarpans, isoflavanes, isoflavanes-3-enes, 3-arylcoumarins, 3-aryl-4-hydroxycoumarins, coumestanes, coumaronochromones or 2-arylbenzofurans.
- isoflavonoids their methods of analysis and their sources, in chapter 5 of the work by P. M. Dewick: "Isoflavonoids", in The Flavono ⁇ ds, Harbone donating, pp. 125-157 (1988).
- the isoflavonoids suitable for use in the present invention can be of natural or synthetic origin.
- natural origin is meant the isoflavonoid in the pure state or in solution at different concentrations, obtained by different extraction processes from an element, generally a plant, of natural origin.
- synthetic origin is meant the isoflavonoid in the pure state or in solution at different concentrations, obtained by chemical synthesis.
- isoflavonoids of natural origin there may be mentioned: daidzein, formononetin, cuneatin, genistein, isoprunetin and prunetin, cajanin, orobol, pratensein, sandalwood, junipegenin A, glycitein, afrormosine, retusin, tectorigenin, irisolidone, jamaicin, and their analogs and metabolites.
- isoflavones among the isoflavonoids, it is preferred to use isoflavones. More preferably, it is preferred to use according to the invention the simplest aglycone forms among which daidzein, genistein and their mixtures. These two compounds are especially present in the soy extract (Glycina max). Methods for preparing isoflavones are described in particular in international applications WO 95/10530, WO 95/10512 and WO 97/26269, American patents US-5,679,806, US-5,554,519, and European patent EP-812 837.
- Isoflavones are in particular known as antioxidants, for their anti-radical and depigmenting properties, as well as for inhibiting the activity of the sebaceous glands (see in particular DE-44 32 947). They have also been described as agents to prevent signs of aging of the skin, including sagging skin and loss of radiance (JP 1-96106). It is therefore understood that the combination of IGFI and / or a mimetic compound of IGFI with isoflavonoids as defined above makes it possible to reinforce the anti-aging effects of the composition containing them, in particular when it s acts to prevent or treat the signs of chronological or photo-induced skin aging.
- the composition according to the invention is preferably suitable for topical application to the skin.
