Extracted from the dried leaves of bearberry plant in the genus Arctostaphylos and other plants commonly in the Ericaceae family, arbutin is a beta-D-glucopyranoside of Hydroquinone. It is found in foods, over-the-counter drugs, and herbal dietary supplements . Most commonly, it is an active ingredient in skincare and cosmetic products as a skin-lightening agent for the prevention of melanin formation in various skin conditions that involve cutaneous hyperpigmentation or hyperactive melanocyte function . It has also been used as an anti-infective for the urinary system as well as a diuretic . Arbutin is available in both natural and synthetic forms; it can be synthesized from acetobromglucose and Hydroquinone . Arbutin is a competitive inhibitor of tyrosinase (E.C.1.14.18.1) in melanocytes , and the inhibition of melanin synthesis at non-toxic concentrations was observed in vitro. Arbutin was shown to be less cytotoxic to melanocytes in culture compared to Hydroquinone .
At non-toxic concentrations, arbutin inhibited the activity of tyrosinase in cultured human keratinocytes, while having minimal effect on the expression of tyrosinase mRNA or the synthesis of the enzyme . α-Arbutin produced a concentration-dependent inhibition of melanin synthesis of human melanoma cells, HMV-II . No inhibitory effect on HMV-II cell growth was seen at concentrations lower than 1.0 mM. At concentrations of 0.5 mM of arbutin, tyrosinase activity was reduced to 60% of that in non-treated cells . The addition of arbutin blocked and inhibited α-MSH-stimulated melanogenesis in B16 melanoma cells, brownish guinea pig, and human skin tissue . In a pilot study of healthy male adults exposed to UV B irradiation, topical administration of arbutin inhibited UV-induced nuclear factor-kappaB activation in human keratinocytes . In mouse skin, arbutin counteracted oxidative stress induced by 12-O-tetradecanoylphorbol-13-acetate .
vitamin C, the water-soluble vitamin, is readily absorbed from the gastrointestinal tract and is widely distributed in the body tissues. It is believed to be involved in biological oxidations and reductions used in cellular respiration. It is essential for the synthesis of collagen and intracellular material. Vitamin C deficiency develops when the dietary intake is inadequate and when increased demand is not fulfilled. Deficiency leads to the development of well defined syndrome known as scurvy, which is characterized by capillary fragility, bleeding (especially from small blood vessels and the gums), anaemia, cartilage and bone lesions and slow healing of wounds.
Ascorbic Acid (vitamin C) is a water-soluble vitamin indicated for the prevention and treatment of scurvy, as ascorbic acid deficiency results in scurvy. Collagenous structures are primarily affected, and lesions develop in bones and blood vessels. Administration of ascorbic acid completely reverses the symptoms of ascorbic acid deficiency.

Uses
Indicated for over-the-counter use for epidermal hyperpigmentation in various skin conditions, such as melasma, freckles, and senile lentigines.
Vitamin C is used for prevention and treatment of scurvy. It may be used for pregnancy, lactation, infection, trauma, burns, cold exposure, following surgery, fever, stress, peptic ulcer, cancer, methaemoglobinaemia and in infants receiving unfortified formulas. It is also prescribed for haematuria, dental caries, pyorrhea, acne, infertility, atherosclerosis, fractures, leg ulcers, hay fever, vascular thrombosis prevention, levodopa toxicity, succinyl-choline toxicity, arsenic toxicity etc. To reduce the risk of stroke in the elderly, long-term supplementation with Vitamin C is essential.
Vitsera Serum is also used to associated treatment for these conditions: Mild Lower Urinary Tract InfectionCommon Cold, Deficiency, Vitamin A, Deficiency, Vitamin D, Fever, Flu caused by Influenza, Folate deficiency, Iron Deficiency (ID), Iron Deficiency Anemia (IDA), Oral bacterial infection, Scurvy, Vitamin C Deficiency, Vitamin Deficiency, Nutritional supplementation, Vitamin supplementation
How Vitsera Serum works
Arbutin is a hydroquinone glycoside, however the hydroquinone moiety is not solely responsible for the de-pigmentating actions of arbutin . It acts as a competitive inhibitor of tyrosinase enzyme by acting on the L-tyrosine binding site to suppress melanogenesis and mediate its de-pigmenting actions on human skin . Tyrosinase is an enzyme involved in the regulation of rate-limiting steps during the synthesis of melanin; it regulates the conversion of L-tyrosine into L-dopa, and subsequent conversion of L-dopa to L-dopaquinone . Via inhibition of tyrosinase activity in a concentration-dependent manner, arbutin attenuates the production of melanin in melanocytes. While most studies suggest that arbutin has negligible effect on the tyrosinase mRNA expression, a study assessing the effect of arbutin on melanocyte differentiation inducement system using ES cells propose that arbutin may also downregulate the expression of tyrosinase in addition to its inhibitory action on the enzyme . The contradictory findings across studies may be due to previous studies using terminally-differentiated melanocytes and melanoma cells .
In humans, an exogenous source of ascorbic acid is required for collagen formation and tissue repair by acting as a cofactor in the posttranslational formation of 4-hydroxyproline in -Xaa-Pro-Gly- sequences in collagens and other proteins. Ascorbic acid is reversibly oxidized to dehydroascorbic acid in the body. These two forms of the vitamin are believed to be important in oxidation-reduction reactions. The vitamin is involved in tyrosine metabolism, conversion of folic acid to folinic acid, carbohydrate metabolism, synthesis of lipids and proteins, iron metabolism, resistance to infections, and cellular respiration.
Dosage
Vitsera Serum dosage
vitamin C is usually administered orally. When oral administration is not feasible or when malabsorption is suspected, the drug may be administered IM, IV, or subcutaneously. When given parenterally, utilization of the vitamin reportedly is best after IM administration and that is the preferred parenteral route.
For intravenous injection, dilution into a large volume parenteral such as Normal Saline, Water for Injection, or Glucose is recommended to minimize the adverse reactions associated with intravenous injection.
The average protective dose of vitamin C for adults is 70 to 150 mg daily. In the presence of scurvy, doses of 300 mg to 1 g daily are recommended. However, as much as 6 g has been administered parenterally to normal adults without evidence of toxicity.
To enhance wound healing, doses of 300 to 500 mg daily for a week or ten days both preoperatively and postoperatively are generally considered adequate, although considerably larger amounts have been recommended. In the treatment of burns, doses are governed by the extent of tissue injury. For severe burns, daily doses of 1 to 2 g are recommended. In other conditions in which the need for vitamin C is increased, three to five times the daily optimum allowances appear to be adequate.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever the solution and container permit.
Side Effects
Ascorbic acid does not seem to have any important adverse effects at dosages less than 4 mg/day. Larger dose may cause diarrhoea or formation of renal calculi of calcium oxalate in patients with renal impairment. Ingestion of more than 600 mg daily have a diuretic action.
Toxicity
In an acute oral toxicity study, the LD50-value for β-arbutin is 9804 mg/kg bw for the mouse and 8715 mg/kg bw for the rat . Dermal LD50 value in rat and mouse was reported to be greater than 928 mg/kg bw, according to an acute dermal toxicity study . Extremely high doses may cause ringing in the ears, shortness of breath, convulsions, collapse, vomiting and delirium . Nausea and vomiting were seen individuals with sensitive stomachs following oral ingestion of 15 g of dried uva ursi leaves that contain arbutin .
Precaution
Ingestion of megadose (more than 1000 mg daily) of vitamin C during pregnancy has resulted in scurvy in neonates. Vitamin C in mega-doses has been contraindicated for patients with hyperoxaluria. Vitamin C itself is a reactive substance in the redox system and can give rise to false positive reactions in certain analytical tests for glucose, uric acid, creatine and occult blood.
