Cosmetic composition for improving skin elasticity containing natural extracts {COSMETIC COMPOSITION FOR IMPROVING SKIN ELASTICITY CONTAINING NATURAL EXTRACTS}

The present invention relates to a cosmetic composition for improving skin elasticity containing natural extracts. More specifically, natural extracts are used as skin elasticity improving agents to improve skin elasticity and skin wrinkles while causing less skin irritation and providing skin soothing and skin moisturizing effects. It relates to a cosmetic composition for improving skin elasticity containing natural extracts representing.

The skin protects the body, contains nerve endings that can sense stimulation from the outside, and is also responsible for chemical and physical reactions such as temperature regulation and vitamin synthesis.

The skin is largely divided into the epidermis, dermis, and subcutaneous tissue. The dermis has more moisture than the epidermis and supplies nutrition to the epidermis. When the epidermis lacks nutrients or moisture, the dermis supplies moisture and nutrients, so skin protection and moisture must be provided to prevent the epidermis layer from losing moisture from the outside. If the supply of moisture to the epidermal layer is not smooth, skin drying occurs and the cohesion of keratinocytes decreases, which nourishes the moisture balance of the epidermis and dermis, including the stratum corneum. To reduce this effect, protect the skin and provide sufficient moisture and nutrients. You must supply it to maintain healthy skin.

In particular, the skin is a visible part and plays a large part in determining aesthetic beauty, so keeping the skin moisturized is essential. If the skin is not moisturized, most people say that the skin is dry. However, skin dryness is not necessarily caused by a decrease in skin moisture content. It has been reported that skin dryness is improved by frequently applying moisturizer when the skin feels dry.

Meanwhile, skin elasticity is achieved by elastic fibers composed of elastin present in the dermal layer. These elastic fibers, like rubber, have a very low elastic modulus, so they are easily deformed by even a small force, and can be easily deformed when the force is removed. It easily returns to its original state. In addition, elastic fibers have microfibrils embedded in an amorphous matrix called elastin, and elastin is a very unique material found only in elastic fibers called desmosine and isodesmosine, which are derived from lysine. It is a protein composed of amino acids. These desmosins and isodesmosins form cross-links within long peptide chains, and this structure gives elastin rubber-like properties.

In addition, elastic fibers composed of elastin exist together with collagen fibers called collagen, and it is possible to maintain skin elasticity when sufficient elastin and collagen are present.

However, due to aging and weakening of skin cells (fibroblasts) caused by ultraviolet rays, the production and destruction of elastin progresses, which can lead to a decrease in skin elasticity. Elastin-decomposing enzymes are expressed in the skin by ultraviolet rays, etc., and this enzyme is activated in the skin. It breaks down normal elastin, causing loss of skin elasticity.

In addition, decreased skin elasticity is also caused by damage and decreased production of a protein called collagen, which makes up more than 70% of the skin dermis. Collagen is also broken down by a decomposing enzyme called collagenase caused by ultraviolet rays, etc.

In the past, cosmetics containing synthetic ingredients that inhibit damage or enhance the production of elastin or collagen were used to solve the above problems. However, in the past, synthetic ingredients had the problem of causing skin irritation in users with sensitive skin. .
