Description

Composition for improving skin

The present invention relates to a skin improvement composition exhibiting skin regeneration, atopic improvement, skin moisturization, skin texture improvement, stem cell activity promoting effect.

The epidermis, located at the outermost part of the skin, protects against a variety of external physical, chemical and mechanical stimuli and protects the body from 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. Keratinocytes are cells formed by gradual changes in morphology and function as basal cells, which have been continuously proliferating in the stratum basale, migrate to the stratum corneum. The forming cells are detached from the skin, and the new keratinocytes from the lower epidermal layer repeat the process of epidermis differentiation or keratinization, which takes over the 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 has a function as.

In addition, dry skin, which is considered to be one of the major diseases in modern society, is one of the symptoms caused by skin barrier dysfunction, and recently, environmental pollution, increased dry environment such as apartments and high-rise buildings, increased social stress, It is increasing due to various factors such as excessive bath culture, skin aging, etc., and it is also continuously increasing when severe symptoms require treatment.

Recently, atopic dermatitis, which occurs in 10% of children, is also known to be caused by dry skin, more fundamentally, 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 are widely used in the pharmaceutical or cosmetic field.

However, the use of such moisturizers are mostly temporary relief of symptoms rather than fundamental treatments, and do not show sufficient effects on the treatment of dry skin and skin barrier function including atopic dermatitis. Therefore, it is urgent to develop a material that fundamentally regenerates damaged skin barriers.

Recently, when PPAR alpha (Peroxisome Proliferator Activated Receptor-alpha) present in keratinocytes is activated by binding to its ligand, it has been known to promote the differentiation of keratinocytes and reconstruct the damaged skin barrier. In the case where clofibrate [Non-Patent Document 1] or WY14643 [Non-Patent Document 2] or the like, which is an actually known PPAR alpha agonist, is applied to the skin with damaged skin barrier, the differentiation of keratinocytes is promoted. It has been confirmed that the recovery of the skin barrier is promoted.

In addition, the skin texture in the form of the skin surface is characterized by a three-dimensional microstructure formed by fine lines and significantly different by age and region. The skin texture is divided into primary (about 20-100 ㎛), secondary (about 5-40 ㎛) and tertiary (about 0.5 ㎛) lines according to the depth of the lines. It has a characteristic that the polygon formed by forming the lines and star formation (star formation) is distinct [Non-Patent Document 3].

However, as the body ages or the skin is damaged, the network structure of the fine fine lines collapses and the fine lines (secondary and tertiary, etc.) disappear and the primary lines become deeper and wrinkles are produced. Document 4,5]. In other words, wrinkles, a representative sign of skin aging, are already the accumulation of fine changes that occur over a long period of time.

Developmentally, all components of human skin are known to be derived from ectoderm or mesoderm. Epidermis, hair follicles, sebaceous glands and sweat glands originate in ectoderm, and melanocytes, nerves and special sensory receptors are derived from neuroectoderm. According to the developmental period, embryonic stem cells are differentiated to become cells of the characteristic for each tissue function, and even after adulthood, a certain number of stem cells remain in the tissue. There are mainly two stem cells in the skin. . The first is in hair follicles. It is known to play an important role in regeneration of the epidermis, and also plays an important role in hair regeneration and growth. Second is the basal layer of epidermis. Stem cells in this area are found to play an important role in protecting skin health by controlling not only the epidermis but also the fibroblasts of the dermis. Stem cells here are relatively quantitative and have the advantage of being easily available and are widely used for research on skin stem cells. The skin is continuously renewed, and stem cells existing in the epithelium of the skin, that is, epidermal stem cells of the skin, are involved in the repair of the epithelium after the wound [Non-Patent Document 6]. The epithelial stem cells of the skin are also referred to as skin stem cells, and when the skin stem cells are activated, they can treat skin wounds such as trauma or promote wound healing, and anti-wrinkle of the skin can also be expected. have. Integrin β1 and integrin α6 are used as indicators of skin stem cells, and maintenance of skin stem cells necessary for epithelial morphology and differentiation is reported to be regulated by p63 protein.

Skin stem cells play an important role in maintaining skin health and physiological and biochemical homeostasis. Stem cells present in the skin also cause abnormalities in function due to the effects of aging, and thus various problems occur as the homeostasis of the skin is broken. Therefore, it is possible to improve the various phenomena of skin aging through the activity of these stem cells [Non-Patent Document 7].

In addition, it is safe for the living body, the active ingredient is stable, and above all, the skin regeneration, atopy improvement, skin moisturizing and skin texture improvement activities are more effective than the substances having the effects of existing skin regeneration, atopic improvement, skin moisturizing and skin texture improvement. There is an urgent need for the development of these components.
