Description

A Chinese medicinal composition containing Ligustrum quihoui, pitaya stem extract and fructus Luffae tissue fluid, and its application in skin care product
Technical Field
The invention relates to the technical field of medicines, and particularly relates to a traditional Chinese medicine composition containing ligustrum quihoui, dragon fruit stem extract and towel gourd tissue fluid and application of the traditional Chinese medicine composition in skin care products.
Background
With the continuous improvement of living standard of people, people pay more and more attention to the personal appearance. Therefore, skin care products have become a necessity for life of people. The main problems of face concerned by people are skin aging, dull complexion, melanin deposition and the like. Every time metabolism in a human body occurs, oxidation-reduction reaction occurs, and then free radicals are generated. A free radical is an atom, molecule or group containing an unpaired electron,generally, the redox reaction is characterized by a strong activity, a short lifetime, and a low concentration, and includes free radicals centered on oxygen, free radicals centered on nitrogen, and the like. Some molecules, although not free radicals, e.g. H 2 O 2 But is closely related to the generation and metabolism of free radicals, has strong redox reactivity, and is collectively called Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) together with the free radicals. Due to the strong redox reaction activity of active oxygen/active nitrogen, electrons can be snatched from other molecules, so that cell membrane damage, protein damage, DNA damage and even whole cell function damage are caused. The aging free radical theory considers that the cell free radical is generated too much, when the antioxidant enzyme is insufficient, the free radical can not be cleared in time to cause apoptosis and tissue damage, which are the root causes of body aging. Therefore, the supply of antioxidant substances capable of scavenging free radicals from the outside is an effective method for protecting cells from aging damage.
Facial pigmentation including chloasma, post-inflammatory pigmentation (sunburn) and sunburn, etc., is another skin problem that afflicts consumers. Melanin is a major pigment produced by melanocytes in the skin, and tyrosinase, an enzyme that plays a fundamental role in melanogenesis, is a copper-containing metalloenzyme, has binuclear copper ions, and is the rate-limiting step in melanogenesis. Therefore, the whitening effect can be achieved by inhibiting key enzyme of tyrosinase-melanin generation.
The application of traditional Chinese medicine in skin care has a long history, and a large number of skin care and whitening empirical formulas are reserved in palace for the past. Therefore, the search for natural extracts with skin care effects in traditional Chinese medicines has important economic and social values.
