- the present invention relates to a new use of a composition
- a composition comprising a combination of at least nicotinic acid or an amide of nicotinic acid and at least one sphingoid base.
- PRIOR ART Depigmentation of the skin may be desired under various circumstances, either for a global lightening thereof, or to eliminate or attenuate spots resulting from local pigmentation disorders.
- the pigmentation of the skin is determined by the presence of melanin in the epidermis and the dermis. Melanin is produced by melanocytes located mainly in the basal layer. These melanocytes send dendritic extensions everywhere, between the keratinocytes.
- the enzyme tyrosinase is needed to produce melanin.
- This biosynthesis also called melanogenesis
- melanogenesis is a complex process which is now relatively well known.
- the pigmentation is normally uniform.
- pigmentation can be excessive locally, what is commonly called hyperpigmentation.
- Hyperpigmentation of the skin can include blemishes or disorders of the skin including freckles, senile lentigo, melasma, age spots, pigmentation due to sunburn, post-inflammatory hyperpigmentation due to l , burns, wounds, insect bites, dermatitis, and other small local pigmented lesions.
- Many cosmetic treatment methods for hyperpigmentation exist but none is completely satisfactory.
- exfoliation including chemical exfoliation, or methods having an impact on melanogenesis, using depigmenting agents.
- depigmenting agents commonly used act directly on the vitality of the epidermal melanocytes where melanogenesis takes place and / or interfere with one of the stages of melanin biosynthesis either by inhibiting one of the enzymes involved in melanogenesis, or by intercalating as an analogue. structural of one of the chemical compounds in the melanin synthesis chain, which chain can then be blocked and thus ensure depigmentation.
- Depigmenting agents can be divided into several groups: Phenolic compounds, which include in particular the following compounds: • Hydroquinone and its ethers such as monobenzyl ether, • 4-methoxyphenol, • 4-isopropylcatechol, • 4-hydroxyanisole and, • N -acetyl-4-S-cystaminylphenol, - Non-phenolic compounds, which include in particular the following compounds: • Corticosteroids, • Tretinoin, • Azelaic acid, • N-acetylcysteine (NAC), • Ascorbic acid and derivatives such as L-ascorbyl-2-phosphate and, • Kojic acid, Combinations of these compounds, among which there may be mentioned the Kligman formulation, the Pathak formulation or the Westerhof formulation.

- Application WO 99.47114 also describes compositions essentially comprising nicotinic acid or nicotinamide as well as an intermediate or precursor of ceramides, used only for hydration of the skin and not for its depigmentation.
- sphingoid bases such as phytosphingosine and sphingosine, precursors of ceramides, are present in human skin, and studies have shown that these molecules have inhibitory properties of protein kinase C, and seem to be involved in differentiation of keratinocytes of the epidermis.
- sphingosines present in the stratum corneum and other layers of the epidermis inhibit the growth of certain undesirable microorganisms.
- Various publications describe the use of sphingosine and phytosphingosine in cosmetic and dermatological compositions.
- patent application WO 95.03028 describes sphingosine, used in a composition with a pH close to 5, to reduce the irritant effect of certain alpha-hydroxy acids.
- Patent EP 940,140 describes a cosmetic composition combining alpha-hydroxy acids and ceramides or precursors of ceramides such as phytosphingosine.
- sphingoid bases have not been found to be effective as depigrants.
- EP 919,226 relates to a cosmetic composition based on phytosphingosine salicylate capable of having anti-acne, anti-wrinkle or lightening properties. the skin.
- the composition can also contain various usual ingredients of the technique such as vitamins A, C and E, used according to their well known properties. It is also known from patent application WO 02/085362 that a composition essentially comprising nicotinic acid or an amide of nicotinic acid and a sphingoid base is useful for the treatment of keratinization disorders in human or animal dermatology .
- the subject of the invention is therefore the use of a composition comprising a combination of at least nicotinic acid or an amide of nicotinic acid and at least one sphingoid base as depigmenting agent .
- the subject of the invention is also a method of depigmentation of the skin, consisting in applying to the exposed areas a composition comprising a combination of at least nicotinic acid or an amide of nicotinic acid and at least one base. sphingoid.
- the subject of the invention is more particularly the use of a combination of at least nicotinic acid or an amide of nicotinic acid and of at least one sphingoid base to promote lightening of the skin as well as the associated cosmetic treatment method.
- a more particular subject of the invention is therefore also the use of a combination of at least nicotinic acid or an amide of nicotinic acid and at least one sphingoid base to combat hyperpigmentation of the skin as well as the associated cosmetic treatment method.
- the invention also relates to a cosmetic treatment method for the skin intended to reduce, eliminate or avoid pigmentation spots, by providing a depigmenting or lightening effect consisting in applying to the exposed areas a composition comprising a combination of minus nicotinic acid or an amide of nicotinic acid and at least one sphingoid base.
- a subject of the invention is finally the use of a combination of at least nicotinic acid or an amide of nicotinic acid and at least one sphingoid base, for the preparation of a dermatological composition intended for combating against hyperpigmentation.

- the sphingoid base can be chosen from sphingosine, sphinganine, phytosphingosine, salicyloyl phytosphingosine, phytosphingosine salicylate, tetracetylphytosphingosine, N-acetyl phytosphingosine and phytosphingosine hydrochloride.
- the preferred sphingoid base is phytosphingosine, salicyloyl phytosphingosine (N-salicyloyl phytosphingosine) or phytosphingosine hydrochloride.
- the nicotinic acid, or the nicotinic acid amide can be used in an amount of 0.1 to 15% by weight relative to the total weight of the composition, and preferably from 1 to 10%.
- the sphingoid base content can vary depending on the base used, but it is generally between 0.01% and 5%, preferably between 0.05 and 2%.
- Nicotinic acid and nicotinic acid amide, especially vitamin PP, as well as the sphingoid bases used in the compositions of the present invention are generally commercially available and can be obtained by known methods from various sources. appropriate.

- the compositions, the use of which is the subject of the present invention can be applied directly to the skin at the rate of one or more applications per day for a duration adapted to the duration of the affection.
- Example 1 A blind study on volunteers was carried out during the sunny period (8 volunteers per product). This study is based on a global evaluation of the color parameters of the back skin of the hands in a “before” versus “after” use mode. The products were applied to the entire hand and the effect was evaluated at the level of pre-selected pigment spots and at the level of an area free from stains (called the "control" site). Each volunteer used a sun protection cream on the hands to minimize the risk of hyperpigmentation which could appear under the influence of ultraviolet radiation linked to sunlight during the experiment. The following parameters were studied: geometry of the spots (size), melanic index on the spot and on the "control” site and, - luminance (L *) on the spot and on the "control” site. The analysis concerns the evolution of the parameters between the first and the last day of the study for the applied products. The composition of the products studied is as follows:
- Vitamin PP Depigmenting Formula 1 0 g, 0% Formula 2 5 Q. 0 Salicyloyl Phytosphingosine 0, 1% Formula 3 5 g. ⁇ Formula 4 0 o. o Arlatone dio ⁇ c Formula 5 0 ⁇ Albatin
- formula 1 is the placebo formula
- formula 2 is based on the “active base” containing vitamin PP at a concentration of 5%, in which a sphingoid base has been added, while formula 3 contains the same dose of vitamin PP without phytosphingosine.
- Formulas 4 and 5 are commercially available compositions containing listed depigmentants, namely octadecene dioic acid (Arlatone dioic) and aminoethylphosphinic acid (Albatin).
- listed depigmentants namely octadecene dioic acid (Arlatone dioic) and aminoethylphosphinic acid (Albatin).
- the results obtained show that: - For formulations 1, 2 and 3, the geometry of the spots does not change significantly over time. - The luminance (L *) of the skin increases (the color of the skin becomes lighter) at the level of the spots and at the level of the “control” zone for formula 2. - The melanic index decreases (less melanin is present) at the spot level and at the level of the "control" zone for formula 2.
- TRIO D is a depigmenting composition based on ammonium lactate, ascorbic acid and glabridin at a concentration of 0.1%.
- TRIO A includes the same active ingredients and glabridin at a concentration of 0.2%.
- Formula C of the invention contains the same concentration of glabridin, which is a compound known for its antityrosinase activity. Attempts.
- compositions being in ethanolic solution buffered to pH 6.8 containing 500 ⁇ l of tyrosine solution and 500 ⁇ l of tyrosinase solution, and the control used is identical but does not contain depigmentant.
- a blank control is identical to the control but the tyrosinase is replaced by the same amount of water.
- a blank test is prepared using the same sample of formula to be tested but by replacing the tyrosinase with the same amount of water. It is left to incubate for 1 hour in a water bath at 37 ° C protected from light and then the tubes containing the formulas tested are cooled in a cold water bath to about 18 ° C. The absorbance of the solutions is measured at 475 n in a 10 mm tank. The results are collated in the following table.
- the average inhibition rate for an amount of lmg product was obtained by averaging the measurements of each formula (3 measurements per formula) compared to an amount of product of 1 mg. It is therefore found that the formula C according to the invention has a significantly higher antityrosinase activity than the reference formulas, resulting in a greater depigmatory power. It is noted in particular that the inhibition rate is doubled compared to formula B which contains the same glabridin content. This demonstrates the effect of the combination of vitamin PP and phytosphingosine on depigmentation.
- the examples which follow relate to formulations containing an association the use of which is the subject of the present patent application. The names of the components are taken from the INCI nomenclature.
