Look for skincare products with 8% vitamin C and 0.9 per cent vitamin A. Sunscreen goes without saying, but to dodge the sun’s ageing effects you want a crack team of integrative potions. “When I was 27 I was advised to use a vitamin C serum in the morning to stop pigmentation and a good physical sunscreen with zinc to prevent sun damage,” says aesthetic nurse Mike Clague from The Me Clinic (formerly The Ashley Centre). Vitamin C, which also goes by the name L-ascorbic acid, is a potent antioxidant that stops skin from oxidising (skin’s take on rusting) in sunlight. Cosmetic physician Dr Ron Feiner, from Cosmetica Medical Aesthetic Clinic, says daily application of a quality vitamin A – also known as retinol and retinoic acid – may also “afford a degree of skin cancer protection”.
NOTE TO SELF: To actually work, vitamin serums need to contain a certain percentage of their active ingredient, says Clague, the brains behind Regenerate Skincare. Department store products often fall short of the recommended 0.9 per cent for vitamin A and eight per cent for vitamin C. Sunscreen should have 10 per cent or more zinc oxide, Clague says. When in doubt, shop at a clinic or online. Another ideal product, recommended by esteemed dermatologist and cosmetic surgeon , is , which removes dead skin cells and is excellent for fine lines. This versatile product is recommended for both prematurely aged and acne prone skins.

The reference range of vitamin C is 0.6-2 mg/dL.
Scurvy is caused by prolonged dietary deficiency of vitamin C (ascorbic acid). Vitamin C levels generally reflect recent intake amounts more than body stores. Vitamin C levels of less than 0.3 mg/dL indicate significant deficiency, while levels that exceed 0.6 mg/dL indicate sufficient intake. There is no known toxic level of vitamin C. [2] However, limited studies have suggested that levels greater than 3 mg/dL may be associated with uricosuria and, in persons with glucose-6-phosphatase deficiency, may induce red blood cell fragility. Specifics for collection and panels are as follows: Vitamin C is sensitive to heat and light, [3] so the specimen should be immediately placed on wet ice and processed within 4 hours. Centrifuge and place plasma in an amber vial to protect it from light. The specimen should be stored frozen. Reject for gross hemolysis but not mild hemolysis or lipemia or icterus. Vitamin C, also known as ascorbic acid, is a water-soluble vitamin.
It is required for the synthesis of collagen, L-carnitine, and neurotransmitters. Vitamin C is also involved in protein metabolism. Vitamin C is a strong antioxidant and has been shown to regenerate other antioxidants such as vitamin E. Vitamin C also plays an important role in immune function and improves the absorption of nonheme iron. Vitamin C cannot be produced by humans but is readily available in many types of food. Citrus fruits are the best known sources of vitamin C, but red and green peppers, tomatoes, potatoes, and other vegetables are also excellent sources. The body tightly regulates tissue and plasma concentrations of vitamin C. [3] With increasing intake of vitamin C, the body absorbs a decreasing fraction of it, making toxicity extremely unlikely. With 30-180 mg/day of vitamin C intake, there is 70%-90% absorption, whereas, with intake greater than 1 g/day, the absorption drops to less than 50%. Vitamin C is metabolized in the liver and excreted by the kidneys.
The renal threshold for excretion of vitamin C is 1.4 mg/100 mL. Excess vitamin C is excreted unchanged in the urine. When plasma concentrations of vitamin C are low, excretion of vitamin C is decreased. The total body content of vitamin C ranges from 300 mg to 2 g. Vitamin C is stored throughout the body, with highest concentrations in the white blood cells, eyes, adrenal glands, pituitary glands, and the brain. Increased intake of vitamin C has been reported to be beneficial in several health-related aspects, including cancer prevention, cancer treatment, prevention of cardiovascular disease, prevention of age-related macular degeneration and cataracts, prevention of the common cold, [4] improved wound healing, [7] and improved blood pressure control. [3] These studies have largely been epidemiologic in nature, and whether increased vitamin C or other factors are responsible for any possible effect is controversial. None of these studies have shown any benefit associated with a higher vitamin C plasma level, and laboratory testing of vitamin C is not beneficial.
Vitamin C deficiency leads to scurvy. Humans, unlike other animals, are unable to produce vitamin C and therefore depend on dietary sources. Scurvy has been described since ancient times and is best known for its high incidence in sailors. In the 1700s, addition of citrus fruit to the diet of sailors largely cured scurvy in that group, but there were still incidents of “land scurvy” in populations with abnormal diets. Today, scurvy is extremely rare because of improved food supplies, vitamin-fortified foods, and vitamin supplements, but can occur in populations with poor diets. The main function of vitamin C is in the triple-helix formation of collagen; vitamin C deficiency impairs collagen synthesis and results in the typical signs of scurvy. [6] Upon administration of adequate oral vitamin C, the symptoms of scurvy resolve within 1-12 days. Signs of scurvy (vitamin C deficiency) include the following: Radiographic bone findings (infantile scurvy): Subperiosteal elevation;
