Abstract

Provided is a composition for reducing or preventing skin damage, containing extracts of bananas, cherries, and walnuts. According to one aspect of the present invention, the cosmetic composition containing the extracts of bananas, cherries, and walnuts restores expression of catalase, SIRT-1, and MT-1 which can be dwindled in number due to stress hormone, thereby being useful for delaying or preventing skin damage including skin wrinkles and skin aging.

Description

[0001] The present invention relates to a skin aging preventing or improving composition comprising a mixed extract of bananas, cherries and walnuts,

To a composition for preventing or ameliorating skin damage, including extracts of bananas, cherries, and walnuts.

The expression of cortisol activating enzyme is increased in aging skin tissue. In particular, it has been reported that the activity of cortisol is increased in aged skin tissues after menopause and in skin tissues where photoaging by ultraviolet light has progressed. Cortisol is a type of stress hormone that is secreted by organs such as the kidneys, heart, lungs and skin in the body when physical damage or mental stress is applied. In particular, cortisol in the skin is involved in the synthesis of collagen. The long-term secretion of cortisol affects collagen metabolism in the body, reducing collagen synthesis, and ultimately causing skin damage such as atrophodermia.

On the other hand, melatonin is a type of neurotransmitter that induces a sleeping surface produced in the pineal gland of the brain. It is produced after a certain period of time after sunlight and has various beneficial effects in the body. In particular, melatonin removes free radicals and inhibits melanin which makes skin darker, thereby contributing to skin health. When melatonin is applied to the skin, it is possible to prevent erythema formation, mitigate atopic dermatitis, Aging effects and the like have been reported

Accordingly, the present inventors developed a mixed extract of bananas, cherries, and walnuts, which is known to be a natural substance that contains melatonin and helps in sleeping, as a skin wrinkle improving material. In addition, it was confirmed that the mixed extract of bananas, cherries, and walnuts can restore the activity of MT-1, SIRT-1 and catalase inhibited by dermal fibroblasts to prevent skin aging, thereby completing the present invention.

The inventors of the present invention have found that when extracting natural products known to have a sleeping effect for preventing or improving aging, the mixed extract of bananas, cherries, and walnuts is used as an antioxidative factor related to skin aging, catalase and aging-related factor SIRT-1 , And MT-1, which is a melatonin receptor, and thus completed the present invention.

In addition, in the case of the mixed extract of banana, cherry and walnut, the recovery effect of MT-1, SIRT-1 and catalase reduced by the stress hormone was remarkably increased compared with the single extract. In view of this, it can be seen that the mixed extract of bananas, cherries and walnuts shows a synergistic effect more than a simple combination in comparison with the extracts of bananas, cherries and walnuts alone, and that synergy effect can prevent or improve skin aging or wrinkles.

Compositions comprising extracts of bananas, cherries, and walnuts are useful for restoring the expression of MT-1, SIRT-1 and catalase to prevent or ameliorate skin damage.

Specifically, neuroblasts were treated with 1 μM dexamethasone and cultured for 24 hours to obtain a culture solution. Human dermal fibroblasts were inoculated into the culture at a density of ⁴ x ¹⁰ < ⁵ > / well. Then, 1 mL (10 μg / mL) of each of Comparative Example 1-3 and Example 1 was added and cultured in a 5% CO ₂ incubator at 37 ° C. for 24 hours. 100 μL of lysis buffer was added to extract proteins. The Bradford assay was performed on the extracted proteins and the protein was quantified by measuring the absorbance at 595 nm wavelength. In addition, SDS-PAGE was performed and the protein band was transferred to PVDF (Polyvinylidene fluoride, Bio-Rad, USA), and the protein expression level was confirmed by ECL (Enhanced chemiluminescence, ThermoScientific, USA) solution.
