Abstract
Description
Technical Field
[0001] The invention relates to the technical field of daily chemicals, in particular to a moisturizing cosmetic composition. Background Art
[0002] The skin is composed of the epidermis, dermis, and subcutaneous tissue, and contains skin appendages, abundant nerves, blood vessels, lymphatic vessels, and muscles. It is the largest organ covering the human body and is in direct contact with the external environment. In addition to resisting damage to the body from various external factors, it is also a factor that affects external beauty.
[0003] With the improvement of living standards, facial skin care has attracted more and more attention. The goal of facial skin care is to make the skin smooth, moisturized and elastic, which is largely due to the moisture in the skin, and these appearance signs are related to the function of the skin's own moisturizing system. When the epidermal barrier function is impaired, a large amount of water will be lost in the dermis and epidermis. If the skin is dehydrated, it will appear dull, dry, and wrinkled. In severe cases, it may even cause skin scaling and itching. Water is one of the important components of the skin. Water is directly involved in the metabolism of the skin and is closely related to the homeostasis of the skin's internal environment. Rehydrating the skin is essential to maintaining the normal physiological function of the skin and beautifying the appearance. Therefore, skin hydration and moisturizing has become one of the key themes in the research and development of modern cosmetics.
[0004] There are many kinds of hydrating and moisturizing cosmetics on the current cosmetics market, but most of them have poor permeability and are irritating. Some products have a strong greasy feeling, which can easily lead to clogged pores, causing the risk of acne and blackheads, and the use experience is not good; commonly used hydrating and moisturizing cosmetics only have temporary nourishing and moisturizing functions, but it is difficult to repair and care for skin cells, and the effect is not obvious. Therefore, we propose a moisturizing cosmetic composition to solve the above problems.
