Thank you for your understanding It is suggested that arbutin be added to the emulsion to prevent sunburn in summer.Dear customers This is alpha arbutin solution, not cosmetics.

You can't use too much at the same time. You'd better add it to the cream. It can inhibit the formation of melanin. It has a strong antioxidant capacity. It can greatly weaken the effect of summer UV. You can even stop using sunscreen. It is recommended to use two bottles of arbutin, you will see a significant effect in a month.What is Arbutin ?Arbutin is a natural active substance derived from green plants.It is a combination of "green plants, safe and reliable" and "efficient decolorization" for skin decolorization.It can quickly penetrate into the skin, effectively inhibit the activity of tyrosinase in the skin, block the formation of melanin, and directly combine with tyrosinase without affecting the concentration of cell proliferation, thus accelerating the decomposition and excretion of melanin.It has no toxicity, irritation, sensitization and other side effects on melanocytes. It also has bactericidal and anti-inflammatory effects. It is the most popular safe and effective whitening material.Ultraviolet light in the sun will activate a large number of free radicals (free radicals will attack cells). When the cells in the skin epidermis feel the free radicals ready to move, they will send out a distress signal to the deeper melanocytes. Generally speaking, it includes the following processes:(1) Ultraviolet light stimulates the production of free radicals.(2) Cells in the epidermis sense the crisis and send out a distress signal.(3) Melanocytes receive distress signals and start melanin production process to provide material support for epidermal cells.(4) The raw material of melanin production is tyrosine, and the production workers are tyrosinase, so under the call of the boss, tyrosinase is activated.(4) Tyrosinase catalyzes the production of DOPA from tyrosine and further evolves into melanin.(5) Melanin cells protrude, package melanin, and contact transportation companies to transfer and release melanin to the surface of skin, which can protect the epidermal cells and resist foreign enemies. So the formation of black spots, a large number of black spots on the skin looks black.In which step does arbutin play a role?Arbutin can inhibit the activity of tyrosinase, which can be understood as inviting melanin production workers to drink and eat meat, and then a general strike, thus inhibiting the formation of melanin from the source.Therefore, the whitening principle of arbutin is different from that of nicotinamide. Arbutin is to seize the core and strangle from the source, while nicotinamide can only prevent the melanin that has been generated from being transported to the epidermis.Raw material composition:Inhibition of melanin production:Our raw materials include AA2G, arbutin and its derivatives, kojic acid and its derivatives, vitamin C and its derivatives, endothelin antagonists, licorice flavonoids, anthocyanins, green tea, Rhododendron, grape seeds, Rhodiola and other plant extracts, which can inhibit melanin formation by 90%Stop melanin transport:After melanocytes produce melanin, melanocytes will transport along the dendrites of melanocytes to the surrounding keratinocytes and affect skin color. Melanin transport blocker can reduce the transfer speed of melanosomes to keratinocytes, reduce the melanin content of epidermal cells, and achieve whitening effect. Therefore, we use nicotinamide, azelaic acid, green tea extract, etc.Before the introduction of ursolic acid, we first introduced a substance: hydroquinone. It can interfere with the formation of melanin, so as to achieve the whitening effect. However, due to its irritation, it may cause irritative dermatitis and pigmentation, so it is listed as a prohibited product in many countries / regions. Ursolic acid introduces glucose molecules into the molecule, This reduces irritation. It has the ability to interfere with melanocytes and dilute melanin formed. It has good
