Problems solved by technology

[0003] At present, there are many whitening and freckle-removing products in the industry. The main principles of treating spots are: (1) Inhibit the production of melanin --- by inhibiting the production and activity of tyrosinase, or interfering with the intermediates of melanin production, so as to prevent melanin Commonly used whitening agents include: arbutin, kojic acid, vitamin C, hydroquinone, azelaic acid, etc., but after use, it is easy to cause skin inflammation, erythema, skin tingling and other side effects, and there are some natural whitening agents , safe and effective, but expensive and less stable
(2) Reduction of melanin, prevention of photo-oxidation—stimulate the reduction of melanin through keratinocytes, so that the melanin that has already been produced is lightened; (3), Promote the metabolism of melanin—improve the metabolism of the skin, and make melanin rapidly It is excreted from the body; it mainly uses some keratin exfoliants to exfoliate the aged keratin, accelerate skin metabolism to achieve whitening effect, and usually use fruit acid (AHA), salicylic acid (BHA) and retinoic acid, etc., but long-term use can improve skin. Hydration and firmness, but often with stinging and erythema, which can burn the skin in severe cases
However, physical sunscreens are prone to whitening due to their poor smear feeling, and long-term large-scale use can easily clog pores and cause acne; chemical sunscreens are prone to photoallergic reactions, leading to skin irritation. When the skin is stimulated for a long time, it will become Roughness, bumps, itching symptoms, etc., even cause changes in the deep layers of the skin

Abstract

The invention relates to the field of cosmetics, and provides a skin care product for skin whitening and a preparation method thereof. The skin care product for skin whitening provided by the invention comprises oil-phase raw materials, water-phase raw materials and third-phase raw materials, wherein the oil-phase raw materials comprise an emulsifying agent, an emollient and succinate dimethoxy-methyl-nor-aporphine; the water-phase raw materials comprise a skin humectant, a metal chelating agent and reverse osmosis water; and the third-phase raw materials comprise a preservative and perfume. The calcium current principle is adopted to impede the activation of tyrosinase for the skin care product for skin whitening and preparation method thereof provided by the invention, thus the effects of skin whitening and color spot fading are achieved. The skin care product for skin whitening provided by the invention is added with nor-aporphine derivatives, thus the skin care product can interfere the inflow and outflow of the calcium current in cells; and the activation of protein kinase C is inhibited by an adrenergic antagonist which locks the calcium exchange, thereby impeding the activation of tyrosinase, achieving the effects of skin whitening and color spot fading.
