Description

The present invention relates to one or more selected from Rhizophora L. plants and a cosmetic method by applying ghetto to the skin.

  Conventionally, extracts of many kinds of plants including medicinal plants have been used for external preparations for skin (for example, Non-Patent Document 1, Non-Patent Document 2, etc.). In recent years, with the increase in plant orientation due to nature and animal welfare, there is an increasing tendency to seek active ingredients in plant and fungal extracts.

  However, although plant and fungal extracts each have a variety of actions, the action is generally not so strong, and the external preparation for skin contains an amount of plant or fungal extract that produces the expected action and effect. In some cases, unfavorable coloring and odor were observed, and the stability of the preparation was decreased. Although attempts have been made to enhance the action and effect by using multiple plant and fungal extracts in combination, various factors are involved in the physiological functions of the skin, so the skin condition must be sufficiently improved. It is difficult.

  In addition, as for the use of the plant belonging to the genus Yaeyama Hirugi, an external preparation for the skin containing the genus Hygiaceae such as Yaeyama Hirugi (see Patent Document 1), and a cell activator and an antioxidant (Patent Document 1) containing the extract of the plant belonging to the genus Yaeyama Hirugi as an active ingredient Reference 2) is disclosed, but it has not been known that the moisturizing effect is synergistically improved by using a plant belonging to the genus Yaeyamahirugi and a specific plant or fungus.

  As a combination of ghetto to the external preparation for skin, acne and rough skin improvement effect (see patent document 3), bactericidal effect (see patent document 4), hair growth / hair growth effect (see patent document 5), hyaluronic acid production promoting effect (see patent document 5) Patent Document 6) and the like are disclosed.
