Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a whitening and freckle-removing composition and a preparation method and an essence thereof. Background Art

[0002] With the improvement of living standards, people pay more and more attention to skin beauty, and whitening and removing spots has become one of the skin care goals pursued by many consumers. The causes of dull skin and spots are relatively complex, including ultraviolet radiation, endocrine disorders, aging, stress and many other factors. These factors can cause melanocytes in the skin to be overactive, produce a large amount of melanin and deposit, so that the skin will have spots, dullness and other problems, affecting the appearance. Although there are many whitening and spot removal products at present, many products have defects such as poor effect, large irritation of ingredients, and poor stability, which are difficult to meet consumers' demand for efficient and safe whitening and spot removal skin care products. Therefore, it is of great practical significance to develop a composition with significant whitening and spot removal effects, mild ingredients and feasible preparation process. Summary of the invention

[0018] Beneficial Effects The whitening and freckle-removing composition of the present invention can achieve good whitening and freckle-removing effects through the synergistic cooperation of various components. Among them, the extract of the flower of Saururus chinensis is rich in various active ingredients, which can inhibit the synthesis of melanin from the source, regulate the activity of tyrosinase, reduce the generation of melanin precursor substances, and lay the foundation for whitening and freckle-removing. Nicotinamide can effectively prevent melanin from transferring to epidermal keratinocytes, thereby reducing the appearance of spots on the skin surface. α-Arbutin can competitively inhibit the activity of tyrosinase and directly interfere with the synthesis process of melanin. Algae extracts such as Sargassum obtusifolia extract, Chondrus crispus extract, Fucus vesiculosus extract, Glechoma longituba extract and Gelidium pseudocarpon extract are rich in various minerals, vitamins and unique seaweed polysaccharides and other ingredients. On the one hand, these ingredients of the algae extract can supplement nutrition for the skin, enhance the vitality of skin cells, promote skin metabolism, and accelerate the decomposition and discharge of melanin. On the other hand, the seaweed extract also has a certain moisturizing effect, which can keep the skin moisturized and create a good skin environment for whitening and freckle-removing. Nonapeptide-1 can reduce the amount of melanin produced by melanocytes by regulating the signal transduction pathway of melanocyte stimulating hormone (MSH). Cyclodextrin plays a stabilizing and solubilizing role in the composition. It can encapsulate some easily oxidized or unstable components, improve the stability of the composition, and ensure that each active ingredient can fully exert its efficacy. Yeast lysate extract is rich in nutrients such as amino acids, vitamins, and polysaccharides. It can nourish the skin, repair damaged skin barriers, and enhance the skin's self-defense capabilities. At the same time, it cooperates with other components to enhance the overall whitening and freckle removal effect of the composition. DETAILED DESCRIPTION
