- the skin is an organ in its own right that plays an essential role, not only in protecting the body against external aggressions, but also aesthetically and emotionally.
- the skin is an organ of exchange. Its visual but also tactile aspect occupies a very important place.
- the skin as an organ is directly exposed to external conditions, including temperature, light, humidity, UV rays and pathogens. Under normal, healthy conditions, many attributes of human skin follow a periodicity: hydration and transepidermal water loss, capillary blood flow, sebum production, temperature, surface pH and rate. keratinocyte proliferation.
- compositions in the state of the art for the treatment of skin aging and/or for firming the skin.
- these compositions have relative efficiencies, even disputed in certain cases by consumer associations.
- the relative effectiveness of the known compositions may be at the origin of a need for individuals to resort to surgical procedures such as the injection of hyaluronic acid and/or botulinum toxin in order to mask wrinkles.
- a cosmetic composition according to the invention advantageously allows an action on the aesthetics and aging of the skin and/ or its appendages and/or mucous membranes, in particular to provide radiance, suppleness, finesse, smoothing and/or softness.

- EXAMPLE 1 EFFECTS OF COMPOUNDS OILY MACERATE OF BEECH BUDS, AQUEOUS EXTRACT OF BEECH BUDS, SAP OF WHITE BIRCH AND THEIR COMBINATIONS ON THE EXPRRESSION OF GENE IN NORMAL HUMAN EPIDERMAL KERATINOCYTES
- NHEK normal human epidermal keratinocytes
- NHEK Normal human epidermal keratinocytes
- Serum-free medium Keratinocyte-SFM
- EGF epidermal growth factor
- EP pituitary extract
- gentamicin 25 ⁇ g/ml
- Test medium Serum-free medium (Kératinocyte-SFM) supplemented with gentamicin 25 ⁇ g/ml.
- the cells were incubated in the presence of WST-8 (highly water-soluble tetrazolium salt) reduced to an orange-colored water-soluble product (formazan) by succinate dehydrogenase (mitochondrial enzyme). This transformation is proportional to the number of living cells and their metabolic activity.
- the optical density (OD) was measured with a spectrophotometer at 450 nm (VERSAmax, Molecular Devices).
- the keratinocytes were seeded in 24-well plates and cultured in culture medium for 24 hours then in test medium for an additional 24 hours. After incubation, the culture medium was replaced with test medium containing or without (control) the compounds, the combinations or the solvent control (1% THF) and the cells were incubated for 24 hours.
- the culture supernatants were removed and the cell layers were rinsed with a solution of phosphate buffered saline (PBS).
- PBS phosphate buffered saline
- RNAs extracted from cell layers of each experimental condition were pooled before RNA extraction.
- RNAs of each sample were extracted using TriPure Isolation Reagent ® according to the protocol recommended by the supplier. The quantity and quality of the RNAs were evaluated by capillary electrophoresis (Bioanalyzer 2100, Agilent).
- the complementary DNAs (cDNAs) were synthesized by reverse transcription of the total RNAs in the presence of oligo(dT) and the reverse transcriptase enzyme “Transcriptor Reverse Transcriptase” (Roche). The amounts of cDNA were then adjusted before the PCR step.
- PCR reactions (polymerase chain reaction) were carried out by quantitative PCR (Light Cycler; Roche Molecular Systems Inc.) and according to the procedures recommended by the supplier.
- reaction mix (final 10ml) for each sample contained:
- reaction mixture containing the Taq polymerase enzyme, the SYBR Green I marker and MgCL the reaction mixture containing the Taq polymerase enzyme, the SYBR Green I marker and MgCL.
- the standard error of the mean (sm) represents the standard deviation of the sample mean from the true population mean.
- the esm is calculated by dividing the Sd by the square root of the sample size.
- Viability percentage (DOcompound / DOcontrol) x 100
- Fluorescence incorporation into amplified DNA is measured continuously during PCR cycles. These measurements make it possible to obtain fluorescence intensity curves as a function of the PCR cycles and thus to evaluate a relative expression value for each marker.
- the number of cycles is determined from the "exit" points of the fluorescence curves. For the same marker analyzed, the later a sample comes out (high number of cycles), the lower the initial number of mRNA copies.
- the relative expression value is determined by the formula:
- the "MV200714 - mQPA NHEK-8 custom genes" PCR matrices contain 2 reference genes (housekeeping gene or “housekeeping (HK)") used for data normalization: RPS28 (ribosomal protein S28) and GAPDH (glyceraldehyde-3 -phosphate dehydrogenase).
- the reference genes selected are genes expressed constitutively and whose level of expression is not or only slightly affected by the treatments.
- the normalization of the level of expression of the target markers is carried out by comparing their level of expression with the mean expression of these 2 reference genes.
- RPS28 ribosomal protein S28; GAPDH: glyceraldehyde-3-phosphate dehydrogenase; KRT19: keratin 19, type I; KLK7: kallikrein-related peptidase 7; FLG: profilaggrin; AQP3: aquaporin 3 (GUI blood group); S100A7: psoriasin or calcium-binding protein S100 A7; HMOX1: heme oxygenase 1; TGM1: transglutaminase 1
- the white birch sap compound tested in combination with the oily macerate of beech buds induced an increase in the expression of genes involved in cell proliferation (KRT19), the barrier/hydration function (FLG) as well as the response to stress oxidative and cellular (HMOX1).
- KRT19 genes involved in cell proliferation
- FLG barrier/hydration function
- HMOX1 stress oxidative and cellular
- the compound white birch sap (tested at 1%), tested in combination with the compound oily macerate of beech buds (tested at 0.1%) induced an effect synergistic on the modulation of the expression of keratinocyte genes in epidermal regeneration, the barrier/hydration function as well as in protection against oxidative stress and therefore against skin ageing.
- the compound white birch sap (tested at 1%), tested in combination with the compound aqueous extract of beech buds (tested at 0.3%) induced a significant synergistic effect on the modulation of keratinocyte gene expression involved in epidermal regeneration, desquamation, barrier/hydration function as well as in protection against oxidative stress and therefore against skin ageing.
