Description

Skin improvement composition

The present invention has no side effects, and relates to a composition for improving skin having excellent effects on skin regeneration, skin wrinkle improvement, and skin moisturizing effect.

Human skin undergoes a variety of internal and external changes as it ages. Internal factors include decreased secretion of various hormones that regulate metabolism, decreased function of immune cells and activity of cells. External factors include increased free radicals due to ozone layer destruction and increased environmental pollution. And an increase in active harmful oxygen. Due to these internal and external factors, the amount of biosynthesis of immune proteins and constituent proteins necessary for the living body is reduced, causing various changes, that is, aging, including skin problems such as reduced skin thickness, increased wrinkles, or reduced skin elasticity.

As aging progresses, symptoms of changes or decreases in the content and arrangement of collagen, elastin, hyaluronic acid, and glycoproteins constituting the skin appear, and the skin is subjected to oxidative stress by free radicals and active harmful oxygen. In addition, due to the progress of aging or ultraviolet light, the biosynthesis of cyclooxygenase-2 (Cox-2, cyclooxygenase), an enzyme that produces proinflammatory cytokine in most cells constituting the skin, is increased. Biosynthesis of matrix metalloproteinase (MMP), an enzyme that degrades skin tissues by inflammatory factors, increases, and nitric oxide (NO) production by inducible nitric oxide synthase (iNOS) is known to increase.

The collagen is present in the extracellular epilepsy as a major substrate protein produced in the fibroblasts of the skin, and important functions include the mechanical strength of the skin, the resistance of connective tissues and the adhesion of tissues, the support of cell adhesion, cell division and differentiation Induction of growth or wound healing) is known. This collagen is reduced by the above-mentioned internal and external factors, which are known to be closely related to wrinkle formation of the skin. In addition, in recent years, extensive research on skin aging has revealed an important function of collagen in skin.

Conventional active ingredients that promote the collagen synthesis and improve wrinkles are known as retinoic acid, transforming growth factor (TGF), protein from animal placenta, betulinic acid, chlorella extract and the like. However, the active ingredients are limited in the amount of use due to safety problems such as irritation and redness when applying the skin, or the effects are insignificant such that the effect of substantially promoting the collagen synthesis of the skin can not be expected to improve the skin function. Have

In addition, the epidermis located at the outermost part of the skin performs protection against various physical, chemical and mechanical stimuli from the outside and prevents excessive release of moisture through the skin. This protective function is possible by the normal formation and maintenance of the stratum corneum consisting of keratinocytes. The keratinocytes are cells formed by continually proliferating in the stratum basale, while the basal cells move through the stratum corneum, undergoing morphological and functional changes in stages. Keratinocytes are dislodged from the skin, and new keratinocytes from the epidermal substratum repeat the process of epidermis differentiation or keratinization, replacing their function. In this keratinization process, keratinocytes produce natural moisturizing factor (NMF) and intercellular lipids such as ceramides, cholesterol, and fatty acids, and the stratum corneum acts as a barrier to the outside, resulting in a skin barrier. It will function as.

Recently, skin dryness caused by abnormal skin barrier function due to various factors such as environmental pollution, increase of dry environment such as apartments and high-rise buildings, increase of social stress, excessive bath culture unique to Korea, skin aging, etc. has been increasing. In addition, cases of severe symptoms that require treatment also continue to increase.

Atopic dermatitis is also an example of dry skin, more fundamentally due to abnormal skin barrier function. In order to treat such atopic dermatitis, a lot of researches have been conducted to supply moisture from the outside or minimize the loss of water from the body, focusing on maintaining proper moisture in the skin. Moisturizers such as ceramide) or derivatives thereof have been developed and used in the pharmaceutical or cosmetic field. However, the use of such moisturizers are mostly temporary relief of symptoms rather than fundamental treatment, and do not show sufficient effects on the treatment of dry skin and abnormal skin barrier function including atopic dermatitis. Therefore, it is urgent to develop a material that fundamentally regenerates damaged skin barriers.

Accordingly, the present applicant has intensified the research on ingredients that are safe for the living body and the active ingredients are stable in the formulation, and above all, have a significant improvement effect compared to the active ingredients for improving the existing skin. As a result, the combination of ginsenosides and glyceryl glucosides, which have excellent effects on anti-aging, promotes transepidermal absorption of ginsenosides, thereby doubling their efficacy and significantly improving skin moisturizing effects.
