Description

    COMPOSITION FOR CARING FOR KERATIN MATERIALS TECHNICAL FIELD
  • The present invention relates to a cosmetic composition. In particular, the present invention relates to a composition for caring for keratin materials. The present invention also relates to a non-therapeutic method for caring for keratin materials.
  • BACKGROUND ART
  • Human skin is constituted of three compartments, namely a superficial compartment, which is the epidermis, the dermis and a deep compartment, which is the hypodermis.
  • The dermis is mainly constituted of fibroblasts and an extracellular matrix (ECM) . This extracellular matrix is constituted of various macromolecules responsible for the mechanical strength of the skin, its suppleness, its tonicity and its elasticity, and also for physiologically important functions (hydration, thermoregulation and regulation of the permeability of the skin) . These macromolecules include, in particular, collagens, elastin and glycoconjugates (glycoproteins and proteoglycans) .
  • Collagens represent 70%of the proteins of the ECM. Naturally, collagens are constantly renewed, but this renewal decreases with age, which leads to thinning of the dermis.
  • It is also known that prolonged exposure to ultraviolet radiation, particularly to type A and B radiation, has the effect of stimulating the expression of collagenases, particularly of MMPI (also referred to as matrix metalloproteinase 1 or else interstitial collagenase) , constituting one of the components of photoinduced or non-photoinduced skin aging.
  • A wide variety of cosmetic products have been used to care for the skin, for example, to resist the ageing of the skin. However, some cosmetic products do not deliver a good skin sensory after application.
  • Thus, there is still a need to formulate a composition for caring for the skin, which can effectively resist skin ageing and deliver a good skin sensory after application.
  • SUMMARY OF THE INVENTION
  • An object of the present invention is thus to develop a composition for caring for the skin, which can effectively resist skin ageing and deliver a good skin sensory after application.
  • Another object of the present invention is to provide a cosmetic process for caring for the skin.
  • The inventors have now discovered that it is possible to formulate compositions for caring for the skin, which can effectively resist skin ageing and deliver a good skin sensory after application.
  • Accordingly, in a first aspect, the present invention provides a composition for caring for keratin materials comprising:
  • (i) at least one Saccharomyces cerevisiae extract;
  • (ii) at least one compound selected from vitamin B3 and derivatives thereof;
  • (iii) at least one divalent metal salt; and
  • (iv) at least one monosaccharide selected from mannose, glucose, galactose, fructose, and combinations thereof.
  • The inventors have found that the composition of the present invention can inhibit MMP-1 production, and effectively resist skin ageing.
  • The inventors have also found that the composition of the present invention also can deliver a good smoothness and softness sensory.
  • In a second aspect, the present invention provides a non-therapeutic method for caring for keratin materials, comprising applying the composition according to the first aspect of the present invention to the keratin materials.
  • Other subjects and characteristics, aspects and advantages of the invention will emerge even more clearly on reading the description and the examples that follow.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • Implementations of the present invention will now be described, by way of example only, with reference to the attached figures, wherein:

  • It can be seen from Fig. 1 that 10J UVA can trigger the MMP-1 increase by 200%, and 0.1μM dexamethasone (DT) can decrease the MMP-1 release obviously as the positive control.
  • It can be seen from Fig. 1 that composition of inventive example 1 can reverse the MMP-1 release induced by UVA more significantly than composition of comparative example 1.
  • In-vivo test
  • 10 experts applied two samples (wherein one sample is composition of invention example 1, the other sample is composition of comparative example 1, 2, 3, or4) on the back of hands each time and evaluate the skin finish in terms of softness and smoothness.
  • As compared with composition of comparative example 1, five experts deem that composition of invention example 1 delivers better softness sensory, four experts deem that there is no difference on softness sensory between the two compositions, and one experts deems that composition of comparative example 1 is better than composition of invention example 1 in terms of softness sensory, while six experts deem that composition of invention example 1 delivers better smoothness sensory, four experts deem that there is no difference on smoothness sensory between the two composition.
  • As compared with composition of comparative example 2, seven experts deem that composition of invention example 1 delivers better softness sensory, and three experts deem that there is no difference on softness sensory between the two compositions, while all of 10 experts deem that composition of invention example 1 delivers better smoothness sensory.
  • As compared with composition of comparative example 3, seven experts deem that composition of invention example 1 delivers better softness sensory, and three experts deems that composition of comparative example 3 is better than composition of invention example 1 in terms of softness sensory, while five experts deem that composition of invention example 1 delivers better smoothness sensory, and five experts deem that composition of comparative example 3 is better than composition of invention example 1 in terms of smoothness sensory.
  • As compared with composition of comparative example 4, six experts deem that composition of invention example 1 delivers better softness sensory and four experts deems that composition of comparative example 4 is better than composition of invention example 1 in terms of softness sensory, while five experts deem that composition of invention example 1 delivers better smoothness sensory and five experts deems that composition of comparative example 4 is better than composition of invention example 1 in terms of smoothness sensory.
  • It can be seen that composition of invention example 1 delivers significantly better softness and smoothness sensory than compositions of comparative examples 1 and 2, and significantly better softness sensory than  composition of comparative example 3, sightly better softness sensory than compositions of comparative example 4.
  • In summary, composition according to the present invention can inhibit MMP-1 production, therefore can effectively resist skin ageing, meanwhile, it can deliver a deliver a good smoothness and softness sensory.
