The skin, which is the largest organ of the human body, occupies about 16% of the entire human body volume. It is directly contacted with the external environment, and protects the human body from many harmful factors that intrude into the human body such as temperature, humidity, dust, It plays an important protective role. However, infants or sensitive adults are easily damaged by various pollutants, strong ultraviolet rays, stress, etc., and it takes time to recover. In recent years, there have been an increasing number of people who complain of skin irritation such as erythema, edema, acne, and itch, thereby reducing skin irritation and inflammation caused by various irritants and reducing anti-inflammatory and sedative It is urgently required to develop a substance having an excellent effect.

One of the biggest skin troubles of sensitive modern man is atopic symptoms. Symptoms of these atopic dermatitis are severe itching. In acute phase, the skin is itchy, reddish, swollen, sprouting up like small rice, or catching small blisters, and the scabs sit. The chronic period is itchy, and the skin becomes hard, thick, streaked, scaly like rice flour, satiated, blackened or whitened. Atopic dermatitis usually begins with an infantile eczema, often called a fever. Among steroids currently in use, steroids are highly effective in anti-inflammatory and immunosuppressive actions, but there are concerns about side effects. If applied for a long time, the skin of the right area can be shrunk, the skin pigmentation is reduced, the infection of the germ can occur, the acne may grow and the skin may become thinner. In severe cases, systemic symptoms due to hormones may occur. Since the age of onset of atopic dermatitis is common in infancy before the age of 5, it is recommended to use a small amount of steroids, rather than a lot of one at a time, when the steroid is used only for a short period of time.

Atopic dermatitis is a more frightening disease with secondary bacterial infections that are more itchy than scratching itself. The skin of atopic patients comes with bacterial infections as a result of long-term rubbing and drying. More than 90% of patients with atopic disease are infected with Staphylococcus aureus, which can be caused by scratching the patient's itch. However, recent reports indicate that the bacteria 's exotoxin stimulates the body' s immune system, causing allergic chemicals It is said that it makes the atopy worse. Therefore, the use of appropriate antibiotics is essential for the treatment of atopy.

However, since there is a fear of adverse side effects of steroid drugs, studies on natural drug preparations have been actively conducted recently. Preparations made from natural products have few side effects and their action is generally mild, persistent, biodegradable and environmentally friendly.

Examples of natural product preparations for sensitive skin include cosmetic compositions for improving healing of atopic skin including white wool, barley, Echinacea, and fermented soybean extract, a cosmetic composition for improving healing of atopic skin, The present invention relates to a method for the production of a herbal composition, which comprises culturing a crude herb extract comprising a herbal extract, Angelica keiskei koidz A composition for external application for skin containing a fermented herbal extract having an excellent effect on skin improvement such as moisturizing, skin irritation alleviation, atopic improvement, and anti-inflammatory effect.

However, the development of a natural formulation which does not have side effects while providing moisturizing effect, anti-inflammation and itching relief, which are essential elements of a therapeutic agent for sensitive skin, is insufficient and research is needed.
