Description

Whitening skin care composition containing herba Violae extract and preparation method thereof
Technical Field
The invention relates to a cosmetic composition containing a plant extract, belongs to the technical field of personal care products, and particularly relates to a whitening skin care composition containing a cymbidium album extract.
Background
Bulbophyllum (academic name: bulbophyllum Thouars) is a plant of the genus Bulbophyllum of the family Orchidaceae, and is a perennial evergreen creeping herb. The main varieties of the herba Bulbophylli Odorati include herba Bulbophylli Odorati, round She Dandou herba Bulbophylli Odoratissim, etc. The medicinal herba Bulbophylli Odorati can be used as a medicine by sun-drying whole herb or pseudobulb or fresh herb.
The Chinese medicinal composition has the advantages of being sweet and spicy in taste, cool in nature, capable of dispelling wind and removing dampness, cooling blood and activating blood, mainly treating high fever convulsion, rheumatalgia, numbness of limbs, carbuncle swelling, pharyngalgia and traumatic injury, and also has the effects of nourishing stomach and promoting fluid production, dispelling wind and removing dampness, detumescence and relieving pain, clearing heat and resolving phlegm, relaxing tendons and bones, nourishing yin and moistening lung and the like.
Related researches show that flavonoid substances contained in the Bulbophyllum can inhibit the activity of tumor cells. Therefore, studies on physiological activities related to the extract of Bulbophyllum can be paid attention to.
With the improvement of the living standard of people, the skin with whitening and health becomes more and more fashionable, and the skin is accelerated to age by the external environment pollutants, so that the skin gradually loses luster and elasticity and turns yellow and black. Among them, melanin produced by the catalysis of the enzyme complex with ammonia in skin cells is a major cause of skin darkening. Therefore, effective inhibition of the activity of the enzyme complex with amino acid is the most important method for maintaining skin whitening, and it is known to retard the precipitation of skin pigments and the generation of wrinkles by acting on skin cells using an antioxidant.
Along with the increasing understanding of the side effects of chemically synthesized antioxidants, natural plant antioxidants are increasingly favored by consumers due to the advantages of green, natural and no side effects, so that the research and development of plant antioxidant whitening skin care factors have great significance.
