Definitions
- the present invention relates to a pharmaceutical and cosmetic composition, and more particularly to a composition comprising in combination at least one beta-hydroxy acid and at least one sphingolipid or a sphingolipid precursor, usable by topical administration for treatments and skin care.
- Sphingolipids are substances essentially comprising a fatty acid, a polar group and a chemical structure called sphingoid base, consisting of a long hydrocarbon chain derived from 2-amino-1,3-diol. It is known that certain sphingoid bases, in particular sphingosine and phytosphingosine, precursors of ceramides, are present in human skin, and studies have shown that these molecules have inhibitory properties of the protein inase C, and seem to be involved in differentiation. keratinocytes of the epidermis. It has also been observed that sphingosines present in the stratum corneum and other layers of the epidermis inhibit the growth of certain undesirable microorganisms.
- Sphingosine or 2-amino-4-octadecene-1,3-diol
- Phytosphingosine or 2-amino-1,3,4-octadecanetriol, is found naturally in the lipids of plants, where there are also some analogs to 16, 19 and 20 carbon atoms. According to the present invention, the names sphingosine and phytosphingosine used here also include these analogs.
- Ceramides amides of fatty acids and sphingid bases
- Ceramides are natural constituents of the surface layers of the skin, and in particular the stratum corneum, and play an essential role in the structure of the skin lipid barrier, but their content tends to decrease with age in significant proportions.
- patent applications FR-A-2,673,179 and FR-A-2,714,829 describe ceramides which can be used in cosmetic or dermatological compositions.
- Patent application FR-A-2,773,074 describes compositions based on ceramides associated with alpha-hydroxy acids, which can be used in dermatology.
- Salicylic acid is known as one of the main beta-hydroxy acids. It has keratolytic, anti-inflammatory and antibacterial properties. However, depending on the concentration, it exerts an irritant effect on the skin which limits its use to a few external treatments.
- Salicylic acid esters have been proposed in low doses, that is to say generally less than 1%, in cosmetic compositions, and for example phytosphingosine salicylate obtained by the action of methyl salicylate on phytosphingosine in the medium basic hot as in patent EP-A-919,226 or salicylates of base spheroids obtained enzymatically or chemically by means of a coupling agent such as 1 hydroxybenzotriazole in the presence of a carbodumide as in WO application. 98.40350.
- patent EP 273,202 describes the use of alpha-hydroxy acids as additives in compositions containing one or more active drug ingredients, in order to improve their activity topically.
- Patent EP 504,862 shows that certain derivatives of alpha-hydroxy acids can be used for the treatment of ment of the atrophy of the skin induced by the topical application of corticoids such as clobetasol propionate.
- Patent EP 413,528 describes compositions which can be used for the treatment of various dermatological conditions such as acne, eczema or psoriasis, containing alpha-hydroxy acids in combination with an amphoteric agent having the effect of increasing the pH of the composition.
- alpha-hydroxy acids make it possible to envisage their use in dermatology for the treatment of certain skin conditions.
- they should be used in relatively low concentrations, not exceeding 10% in free form, due to the side effects they may cause, for example increased sensitivity and skin irritation.
- the various known compositions described above which can be used for dermatological treatments are not always suitable for specific treatments such as that of acne.
- Acne is a pathological condition resulting from occlusion of the upper extremity as well as of the internal part of the pilosebaceous canal by the abnormal multiplication of keratinocytes.
- the androgenic hormonal hyperactivity generally appearing during puberty causes a significant increase in seborrhea in the sebaceous glands, and the obstruction of the pilosebaceous canal causes the formation of retentional lesions in the form of comedones or microcysts. .
- This phenomenon triggers an inflammatory reaction of the skin, which may be in the form of papules or pustules
- papulopustular acne particularly common in adolescents. These lesions are generally located in the superficial dermis. In some cases there is a intense inflammatory reaction accompanying deep lesions reaching the deep dermis, forming nodules and macrocysts (nodulocystic acne) requiring appropriate treatment.
- the work undertaken by the applicant has made it possible to show that the combined use of certain beta-hydroxy acids with certain sphingolipids or sphingolipid precursors, such as sphingosine and phytosphingosine, makes it possible to restore the natural defenses of the skin, and effectively fight against certain skin conditions, more particularly in the case of acne, thus offering an alternative to treatment with antibiotics such as erythromycin.
