The present invention relates to a cosmetic composition for skin moisturizing containing a mixture of marlow extract, aloe vera leaf extract, yam root extract, okra fruit extract, amino acid and seawater as an active ingredient, and a skin barrier without side effects by mixing natural extracts It relates to a cosmetic composition for skin moisturizing containing marlow extract, aloe vera leaf extract, yam root extract, okra fruit extract, amino acids and seawater as a mixture that strengthens the skin and maintains and sustains the moisturizing power constant.

In general, the skin is a body part that is directly exposed to the external environment, and when exposed to excessive ultraviolet rays or contaminants, skin irritation such as erythema, swelling, itchiness, and inflammatory reactions are induced. These skin problems are not only cosmetic problems, but substances produced in the inflammatory reaction process incidentally cause pigmentation, and collagen, elastin, hyaluronic acid, and muco are involved in skin elasticity. It causes skin damage, such as promoting the breakdown of polysaccharides.

According to the free radical theory proposed by D. Harman in the mid 1950s, free radicals destroy cells, cut connective tissue in the skin dermis, or cause cross-linking, making it difficult to maintain moisture in the dermal layer. It causes various problems such as wrinkle formation, skin cancer, cell death, rheumatoid arthritis, atopic dermatitis, and acne.

The causes of the generation of free radicals are known as the phagocytosis of white blood cells, the electron transport system in the process of ATP production in mitochondria, the action of Myeloper Oxide (MPO), ultraviolet rays, tobacco, normal metabolic processes, stress, pollutants, and bacteria. .

The phagocytosis refers to an action by which the cell body accepts foreign substances or bacteria into its body and decomposes and detoxifies it.

Of course, there are antioxidants (radical scavengers) in the human body: SuperOxide Dismutase (SOD), catalase, vitamin E, vitamin C, and ubiquinol, but the antioxidant system is affected by age, pollution, ultraviolet rays, and stress. It is neutralized, and free radicals gradually increase.

Increased free radicals destroy the connective tissues of the dermis, such as collagen, elastin, hyaluronic acid, and mucopolysacchride, oxidizing the lipid part of the cell membrane, resulting in cell destruction, resulting in skin wrinkles. , Dermatitis, acne, and skin cancer.

If the skin structurally loses the moisture retention function of the epidermal layer, it cannot maintain normal skin moisturization, resulting in loss of both skin elasticity and health. Our body occupies most of the water required to maintain life, and in normal skin, moisture accounts for 70% in the body and 10 to 20% in the stratum corneum of the skin's epidermis, so the cells and unique proteins that make up the skin function normally. To be able to do it. Water supplied from the dermal layer moves to the upper stratum corneum mainly by passive diffusion and is finally discharged to the outside of the body. This is called Trans Epidermal Water Loss (TEWL), and it is reported that the transdermal moisture loss is maintained at an appropriate level by sebum components and epidermal lipids, which are components of the lipid membrane of the stratum corneum.

In addition, natural moisturizing factor (NMF), which is a generic term for water-soluble ingredients in the stratum corneum, plays an important role in moisturizing the skin.When the moisture in the stratum corneum is maintained at 10-20%, the skin is smooth and soft. In this state, the body's protective function is normally exercised.

On the other hand, when the moisture in the stratum corneum of the skin epidermis is lowered to less than 10%, the elasticity and flexibility of the skin disappear and become dry and rough. This causes skin dryness because the moisture content of the stratum corneum is less than that of normal skin, and the activity of keratinocytes and fibroblasts decreases, such as causing inflammation and trouble.

In addition, as the moisture retention power decreases, the elasticity of collagen and elastin that supported the pore walls of the skin decreases due to the decrease in skin elasticity, and the power to tighten the pores weakens and the pores increase. It is very important to maintain the moisture content of the stratum corneum above all because the skin barrier collapses due to the increased pores and dryness, and bacteria invade and cause inflammation.

Currently, occlusive agents, which are hydrophobic substances such as petrolatum, lanolin, cocoa butter, mineral oil, jojoba oil, shea butter, silicone, etc., are used to prevent moisture loss in the skin. About 20 to 50 kinds of general raw materials, such as Sodium Lauryl Sulfate, Dimethyl Sulfoxide, Croton Oil, and Sodium Hydroxide, are used. When the above ingredients are added to the product, skin irritation, as well as immune reactions such as itching, allergies, and skin inflammation, increase, and transepidemal water loss as well as the stratum corneum increases, causing skin inflammation.

Accordingly, conventional moisturizers contained in cosmetic compositions are limited in obtaining skin moisturizing effects and protective effects as side effects that cause troubles with irritation and inflammation are accompanied on the skin.

To compensate for this, a component of a structure similar to sebum, a natural moisturizing factor (NMF), a polyol of a trihydric alcohol having three hydroxyl groups (-OH), etc. were used in cosmetics to serve as a moisturizer.

However, depending on the geographic or environmental conditions, the effect of temperature and humidity makes the feeling of use feel sticky or unpleasant, and in some cases, there is a problem of depriving moisture in reverse.

In order to solve this problem, research and development of cosmetics that suppress moisture loss in the skin and increase elasticity and moisturizing power by developing natural bioactive materials from plants and introducing them into cosmetics to improve skin barrier and moisturizing power are becoming active.

Therefore, it is essential to develop a physiologically active material for strengthening the skin barrier and moisturizing power and a stable cosmetic material for maintaining moisture.
