Description

Cosmetic composition for antioxidant and skin soothing improvement containing acerola extract and medicinal buckwheat extract {COSMETIC COMPOSITION FOR ANTIOXIDATION AND SKIN SOOTHING IMPROVEMENT CONTAINING ACEROLA EXTRACT AND HOUTTUYNIA CORDATA EXTRACT}

The present invention relates to a cosmetic composition for improving antioxidant and skin soothing containing acerola extract and medicinal buckwheat extract, and more specifically, to a cosmetic composition containing acerola extract and medicinal buckwheat extract that not only exhibits excellent antioxidant effect, but also exhibits skin soothing effect. It relates to a cosmetic composition for improving skin soothing.

Antioxidant cosmetics have the ability to significantly reduce or prevent the destruction and depletion of skin functions and structures damaged by oxidation, and their purpose is to restore skin damaged by exposure to ultraviolet rays.

In addition, antioxidant cosmetics generally include basic antioxidant cosmetics for preparing and protecting the skin, base, point, makeup antioxidant cosmetics for nails, body antioxidant cosmetics for cleaning, sun care, and suntanning, and pre-shampoo compositions. It can include all cosmetic preparations that can be used on hair, such as shampoo, rinse, treatment, wax, spray, mousse, hair lotion, essence, hair cream, permanent hair dye, temporary hair dye, and perm.

However, as the use of synthetic antioxidants has recently increased, the impact on the human body and safety have become issues, leading to increased consumer rejection, and synthetic antioxidants have a problem in that it is difficult to use them in the form of an aqueous solution due to their availability.

In order to solve the above problems, antioxidants derived from natural products with high stability are being developed, and as antioxidants derived from natural products, for example, natural vitamin E (α-tocopherol) and vitamin C are known. However, since these antioxidants derived from natural products have the polarity of being extremely fat-soluble or water-soluble, their use is limited, and there is a problem in that their antioxidant activity cannot be maintained stably for a long time.

Meanwhile, the skin is a part that is directly exposed to the external environment, and when exposed to excessive ultraviolet rays or pollutants, skin irritation and inflammatory reactions such as erythema, swelling, rash, tingling, and itching are induced. Skin troubles caused by these causes not only cause cosmetic problems, but substances produced during the inflammatory reaction also cause pigmentation of the skin and accelerate the breakdown of skin elastic fibers, leading to an increase in skin wrinkles. It is known that In external skin products used to protect and beautify the skin, the use of surfactants, preservatives, fragrances, sunscreens, pigments, functional ingredients, etc. is inevitable, but these ingredients cause various side effects on the skin. . In particular, ingredients such as AHA (alpha hydroxy acid), retinol, and arbutin contained in functional products for whitening, wrinkle improvement, and exfoliation are the main causes of skin problems, and these side effects The substance is difficult to use in concentrations that produce maximum efficacy.

Accordingly, the recent consumer trend is to prefer cosmetics that are environmentally friendly and hypoallergenic, and to skin soothing and skin irritation relieving substances that can protect sensitive skin from the external environment and irritating substances and prevent and minimize aging. Interest in this is increasing. Recently, as it has become widely known that substances extracted and isolated from natural products are less irritating to the skin and have other pharmacological effects such as astringent and antibacterial effects, various attempts have been made to manufacture cosmetic compositions using natural products. It is being done.
