Description

TECHNICAL FIELD [0001] The present invention relates to a composition for moisturizing a skin containing panaxydol,

The present invention relates to a composition for moisturizing, and more particularly, to a composition which contains pancloside as an active ingredient and has an excellent effect of restoring a damaged skin barrier function and increasing skin moisturizing power.

Skin plays a very important role as a barrier function to protect individuals from the outside. The barrier function is a protection function for protecting against various stimuli (chemicals, air pollutants, dry environment, ultraviolet rays, etc.) from the outside and excessive divergence of water in the body through the skin. Such protection function is a function of protecting the stratum corneum The function can be maintained only when it is normally formed.

The outermost stratum corneum (horney layer) of the epidermis is formed from keratinocytes, and consists of keratinocytes with complete differentiation and a surrounding lipid layer (Marcelo CL et al . , J. Invest . Dermatol . 80 , pp 37-44, 1983).

The keratinocyte is a characteristic cell in which basal cells continuously proliferating in the lowest epidermis undergo a stepwise change in morphology and function and are elevated to the surface of the skin. After a certain period of time, And the new keratinocyte replaces its function. This repetitive sequence of changes is called "epidermal cell differentiation" or "keratinization".

In addition, during keratinization, keratinocytes form natural moisturizing factors (NMF) and intercellular lipids (ceramides, cholesterol, fatty acids) and form stratum corneum, which gives firmness and flexibility to the stratum corneum, barrier function.

Such stratum corneum can easily lose its function due to environmental factors such as excessive washing, bathing and other lifestyle factors, dry air pollutants, and endogenous diseases such as atopic skin and senile skin. In fact, Due to the increasing number of factors, dry skin symptoms and their complaints have been increasing recently.

Therefore, in order to maintain proper skin moisture, various studies have been made to supply water from the outside or to prevent water loss from the body. Various moisturizers having moisture retention ability have been developed. As a skin moisturizing agent, it is common to use a substance capable of increasing water retention in the stratum corneum such as ceramide and essential fatty acid and lipid complex (Rawlings AV et al . , J. Invest . Dermatol. , 5, pp731- 741, 1994).

However, recently, the risk factors for skin are increasing, and changes in dietary patterns slow down the generation and decline of the stratum corneum, and the function of the keratinocyte is reduced, so that the amount of the moisturizing factor and lipid in the stratum corneum is decreased, There is an increasing trend in people with skin that can not function as a skin barrier. Such breakdown of the skin barrier function causes various skin diseases such as dry skin, atopic dermatitis, contact dermatitis and psoriasis. Such diseases can be expected to be alleviated by moisturizing agents having a conventional moisture retention function but it is difficult to achieve fundamental healing.

On the other hand, polyacetylene is an acetylenic hydrocarbon which is distributed in plants such as anthracnose and butterfly, and is known to have an action of analgesic, soothing, antibacterial and the like. Examples thereof include panaxydol, panaxynol ), Panaxytriol and the like. It has been disclosed that pancytopenia has cytotoxicity against cancer cells. However, the efficacy of the compound in relation to skin condition improvement is not yet known in detail.
