    Vitamin C is a redox and acid-base system. It is involved in various enzymatic reactions; among other things it promotes collagen synthesis and acts as a free radical scavenger. In cosmetics, it is added mainly because of its antioxidant component, to prevent the oxidative deterioration of the products and to protect the skin from oxidative stress. The combination of vitamin C and vitamin E is recommendable, as these substances regenerate each other. As an active ingredient on the skin, it counteracts skin aging and reduces the formation of free radicals in the top layer of skin. The transport and availability of vitamin C in the skin is best achieved by encapsulation in liposomes.

    Vit. C stellt eines der wichtigsten Redoxsysteme des Körpers dar. Enthalten in Obst und Gemüse, ist es beteiligt an der Biosynthese und Quervernetzung von Kollagen, führt zu einer Zunahme der Kollagenase-Inhibitor-Proteine (Schutz vor Abbau von Kollagen und Elastin), greift als Antioxidans und über die Deaktivierung freier Radikale in den Stoffwechsel von Steroiden und Aminosäuren ein, aktiviert die Ausdifferenzierung von Ceramiden (epidermale Barriere), wirkt positiv stabilisierend und schädigungsmindernd auf die epidermalen Strukturen und vermindert insgesamt die vorzeitige Hautalterung.

    Vitamins A, D, E and K belong to the fat-soluble vitamins. If we have consumed too much the surplus amount is stored in the body. It is not undangerous, as an overdose of vitamin A can, e. g, cause liver damage. Therefore fat-soluble vitamins should only be taken in small amounts as additional preparations. One can only overdose with food with great difficulty. The B vitamins (B1, B2, B6, niacin, pantothenic acid, folic acid, biotin and B12 as well as the important vitamin C. Overages in water-soluble vitamins are not a problem, as they are given off in the urine. Our skin is a supporting pillar for the entire immune system. It must always be ready — and therefore in the first instance it has vitamin C, as the defensive cells need this vitamin for their work. The meaning of vitamin C goes so far over the positive effects for the skin (collagen fibber building, fixedness of the skin and connective tissue, wound healing). The skin frowns on disease-causing agents, which is an important protective function of the skin. Without vitamin A, the protective cells must give up — they calcify and stop the production of defensive materials. Because vitamin A stimulates in its pure form (retinol) and the derivate beta carotene (which builds vitamin A itself in the body) cell renewal and smoothes the skin. It gives tired cells a push to regularly divide. Through this, growing young cells are encouraged, which makes the skin more resistant and vital. Beta carotene is also the best of internal effective skin protectant against sunlight. Vitamin E protects the cell membrane against free radicals which can attack the cells and through this weaken the immune system. As a skin-guarding substance, Vitamin E comes with an enormously large meaning. The highly important (for the skin) vitamin A can be found in lettuce, spinach, milk products, egg yolks, tomatoes, paprika, oranges and cress. Raw carrots must be mixed with some oil and carrot vegetables must be sautéed in oil or butter in order to make the beta-carotene absorbable by the body.

    Vitamins should work against skin aging and revitalize the hair, and are therefore used in care products as stimulating, protecting and infection-preventing components. The most important components for cosmetics are vitamin A with the precursor beta carotene, vitamin E and the B vitamins, above all biotin. Vitamins may have a caring effect on the skin. They cannot, however, cure any lack of nutrition.

    Daily use for beauty supplement ingredients.

    The optimal daily dose for vitamin C is 300 mg. Because one single smoked cigarette destroys 30 mg of vitamin C, smokers require up to 400 mg of vitamin C daily. 100 grams of oranges have about 35 mg. The daily dose for Vitamin C is 0,8 mg., for beta carotene 1 mg. The optimal daily dose for vitamin E is 12 mg. 100 grams of walnuts contains 20 mg. The daily dose for vitamin B6 is 1.6 mg, for folic acid 100 mcg. Biotin requirements are so low that a lack of the substance almost never takes place. Tests with humans with very tired skins showed that, instead of the normal 1.8 grams of zinc reserves in the body, they only had 0.7 grams. A daily ration of zinc should be 15 mg. The daily need for selenium is 20 to a maximum of 100 mg, but not more! 15 mg per day of iron is needed.

  • Wörterbuch der Kosmetik

    Vitamin is the general nomenclature for important life-supporting organic materials which are not generally constructed in the human organism and therefore should be taken as such in the form of their provitamins in food. The split of vitamins into fat-soluble (A, D, E, K) and water-soluble (B group and C) allows the conclusion of their origin in different foodstuffs. With insufficient vitamins one can have a hypovitaminosis or avitaminosis, with an excess of vitamins one can have a hypervitaminosis, which can cause with fat-soluble vitamins A and D health hazards. For this reason, the use of D vitamins is not allowed in cosmetic products. Most of the known vitamins are indispensable for the health of the skin and hair. They can also show a good effect when used on the surface, and are added to many cosmetic products.

    Fast alle Haut- und Alterungsprobleme sind auf ernährungsspezifischen Mangelerscheinungen der Haut zurückzuführen. Darum haben Nährstofflieferanten wie Vitamine, Spurenelemente, Aminosäuren, sekundäre Pflanzenstoffe und hochwertige essentielle Fettsäuren in kosmetischen Produkten eine hohe Bedeutung für eine gesunde Haut.
