Description

FIELD OF THE INVENTION The present invention relates to a composition for antioxidant, whitening and wrinkle reduction,

The present invention relates to a composition containing an extract of Indigofera pseudotinctoria matsum . More specifically, the present invention relates to a cosmetic composition, a pharmaceutical composition and a food composition for antioxidation, whitening and wrinkle improvement, .

The human skin consists of the epidermis, dermis, and connective tissue including the stratum corneum, and the stratum corneum is composed of a dead cell layer formed through the differentiation process of keratinocyte, the basal cell of the epidermis And is responsible for protecting the human body from the effects of the external environment. There are two major researches on the causes of skin aging. One is "internal aging", which is caused by changes in the function of cells, which are constitutive units of skin, with age, and the other is "external aging" Which can be divided into external environment such as ultraviolet rays, pollution, stress and the like.

As the cells of the skin are exposed to oxidative stress by reactive oxygen species generated in a continuous biochemical reaction for the necessary energy supply in the human body in order to supply necessary energy in vivo, the cellular components such as lipid, protein, It changes carbohydrate and DNA oxidative damage and enzymatic activity, causing various diseases such as skin cancer, and promotes aging. In addition, the biggest cause of external aging is photoaging due to ultraviolet rays, which causes acute and chronic skin injuries such as skin cancer through continuous exposure to UV.

The biosynthesis and degradation of collagen, which is one of the important components of the dermal matrix of skin, plays a key role in inhibiting skin aging. The active oxygen species promotes the expression of matrix metalloproteinases (MMPs) in skin fibroblasts, Thereby promoting skin aging.

In addition, elastin fibers form crosslinks with collagen, and are skin constituents that are important for wrinkle formation that is involved in skin elasticity. The deficiency and aggregation of elastin fibers and the dramatic increase in activity of the elastase, elastase, have been found to be one of the causes of skin wrinkles. Elastase is the only enzyme capable of degrading elastin, and its inhibition is known to be able to radically reduce wrinkles.

On the other hand, human skin color is determined by the concentration and distribution of melanin in the skin. In addition to genetic factors, skin color is also affected by environmental or physiological conditions such as sunlight, fatigue and stress. Melanin is synthesized in melanocytes in the epidermis of the skin. In the melanosome of melanocytes, an enzyme called tyrosinase acts on tyrosine, a type of amino acid, resulting in dopa (DOPA), dopaquinone ), And then it is made through a non-enzymatic oxidation reaction. When such a synthesis of melanin occurs excessively in the skin, it darkens skin tone, and causes spots and freckles. Thus, inhibiting the activity of tyrosinase in the skin to inhibit the synthesis of melanin pigment not only makes it possible to whiten the skin tone to brighten the skin tone, but also to reduce skin irritation caused by ultraviolet rays, hormones and hereditary causes, It can improve constipation.

Accordingly, in the field of cosmetics, research and development on functional cosmetics having antioxidative, whitening and wrinkle-reducing effects have been actively carried out, and studies using natural substances have been continued to prevent toxicity or irritation to the skin.
