Vitamins in skin care products

Today, vitamin is definitely a common ingredient in skin care products, no matter the anti-aging and whitening, moisturizing and wrinkle products, its instruction books were including various vitamins. But sometimes, you can not recognize them at the first time, because in the cosmetic raw material, vitamins have a variety of derivatives!

Vitamin A belonging to the non-prescription products, can make the skin cells work properly, and even make skin cells become more vibrant. But there is a minor irritant, sensitive skin people needed to trial before use it; only use those opaque sealed packaging products, because of various forms of vitamin A repeated exposure to air and sunlight will degrade and deteriorate.

Vitamin A acid (retinoic acid), its true identity is the prescription level vitamin A. The active ingredient is higher than retinol, can promote epithelial cell proliferation, differentiation, Keratolysis and other metabolism, also can promote collagen production, mainly used for acne and aging skin those two problems. Due to vitamin A acid (retinoic acid) is vitamin A derivative, have teratogenic effects, so pregnant women should avoid to oral or topical use vitamin A acid products. In addition, vitamin A acid is greater irritating to the skin, so it needs to establish start using skin tolerability, used once every 3-4 days.

According to tretinoin manufacturer, vitamin A alcohol and vitamin A aldehyde are the derivatives of tretinoin. Protect the skin effects: vitamin A alcohol rub on skin, first turn into A aldehyde, and then converted into A acid, can play the effect. At present, vitamin A aldehyde is closest to the A acid composition, have good anti-acne and anti-aging effect, irritating is far less than the A acid, particularly suitable for those want to use vitamin A acid but afraid of their skin can not withstand.

Nicotinamide and nicotinamide are alias of vitamin B3, sometimes also referred to as “vitamin PP”, has antioxidant and anti-inflammatory effects, help cells to restore energy and whitening skin. Nicotinamide have the effect on repairing stratum corneum lipid barrier, improving damaged skin resistance and deep moisturizing, often used to improve oil secretion strong caused by oil and water imbalance. Nicotinamide is a relatively stable and mild ingredients, it itself has a soothing effect, added to skin care products can neutralize other stimulating ingredients. But there is still a small amount of people show up redness, tingling, itching and other discomfort after use, so that sensitive skin or first use of skin care products containing the ingredient should test on the arm or behind the ear skin.

Pantothenic acid is a water-soluble vitamin B5, also known as nicotinic acid, more used as a moisturizing and sedative in skin care products. Help to remove dry skin scrapings, accelerated deep cell renewal of the epidermis, which can effectively improve the skin dry and moisture loss through its locks water efficiency, for conditioning the skin’s water and oil balance, inhibit the excessive secretion of oils and fats also have some effects. The nature of pantothenic acid is mild, suitable for all kinds of skin, usually does not produce stimulation. but remember not to be confused with the role of pantothenic acid and coenzyme Q10, the latter is more role in antioxidant, enhanced cell activity, delaying senescence and other fields.

Vitamin C and its derivatives, due to the unstable nature of vitamin C, so that vitamin C in the cosmetics mostly in the form of derivate. Wherein the ascorbic acid glucoside with highest stability, also one of the common whitening ingredients in whitening market. In addition to whitening and antioxidation, ascorbic acid glucoside also can stimulate the skin keratin synthesis, in collaboration with other anti-aging ingredient plays a part in against sagging and wrinkles.

Pepper planting and introduction

Pepper, also known as capsicum, hot pepper, spicy, angle pepper, Qin pepper, is a Solanaceae Capsicum plants. Capsicum is belonging to annual or perennial herb. Usually a conical or oblong fruit, when immature is green, after mature turn into bright red, yellow or purple, red is the most common. Capsaicin manufacturer found that the pepper fruit peel contains capsaicin so that make it has spicy taste, can increase appetite. Pepper’s vitamin C content is ranked in the first place in vegetables.

Pepper’s root system is not developed, mainly show that the main root diameter, root less, root growing slow, until the 2-3 true leaves have more secondary lateral roots. Root mass is mainly distributed in the plant around 45 cm, a depth of 10 to 15 cm of soil. Open field cultivation, plant height is 40 to 60 cm. The pepper flowers is bisexual flowers hermaphroditic, self-pollination, natural hybridization rate is around 10%, is an outcrossing plants. The fruit is a berry, conical, but the plants malnutrition, the night temperature is low, the sunshine weak, dry soil or planted too close, the big fruit will be restrained, form small fruit, even if normal fruit. Soil drought, too much fertilizer, plants absorb moisture is inhibited, the fruit also becomes shorter. Pepper seed was flat, micro fold, kidney-shaped, pale yellow or milky white. The seed longevity is general 5 to 7 years, but the useful life is only 2 to 3 years.

Chili’s early birth is germination period, destroy buds generally around 5 to 8 days after sowing, about 15 days appear the first true leaf, buds reveal is the seedling stage. First spica to the main door peppers is the flowering stage. The fruit set to lift seedlings is the fruiting period. Chili optimum temperature is between 15 to 34 degrees. Seed germination suitable temperature is 25 to 30 degrees, 5 to 7 days required for germination, less than 15 degrees or greater than 35 degrees the seeds do not germinate. Seedling stage requires higher temperatures, preferably 25 to 30 degrees during the day, about 15 to 18 degrees during the night, seedling intolerance cold, pay attention to cold production. Pepper in 35 degrees will cause flowers and fruits drop. Pepper demanding conditions of moisture, it is neither the drought tolerant nor waterlogging tolerance. It is suitable to plant in dry air conditions. Chili will wilt death for flooded several hours, so the land selection should be smooth, water or drainage conditions must be convenient. Pepper in neutral and slightly acidic soil can be grown, but its roots are requiring oxygen strictly, should be planted in deep fertile soil, rich in organic matter and good sandy soil permeability or gender soil planting. Pepper fertility requires sufficient nitrogen, phosphorus and potassium, but in seedling stage nitrogen and potassium should not be too much, so as not to make the branches excessive growing, delay flower bud differentiation and results. Phosphorus has an important role in the formation and development of the flower, potassium is the essential element for fruit enlargement, in the production must be done nitrogen, phosphorus and potassium interworking, on the basis of co-enough base fertilizer, do a good fertilization to improve the yield and quality.

Pepper can do the main course, also can be used to do side dishes or soup can also be used as pharmaceutical raw materials. Summer should often use chili as side dishes, and select a lower dry, remove fever food as the main course, such as: duck, shrimp, carp, lean meat, bitter herbs, bitter gourd, sponge gourd, cucumber, lily, toon, kohlrabi and so on.

Pepper is not only delicious, but also can prevent food spoilage and extend the function of the storage time. The experiment proved that the pepper extract that can inhibit the growth of some microbial pathogenicity. But these are clearly not the reason why chili evolved spicy. Pepper contains a divergent heat substance, capsaicin. The capsaicin can influence the taste buds, nerve cells and nasal mucosa. Therefore, it form the spicy we usually feel.

The effect of cysteine

There are any important amino acids present in the human body, including the cysteine, which has the efficacy to promote good health. Cysteine ​​is a non-essential amino acid, this means that the body itself can produce it on their own. However, frequent check-ups and keep the balance of this amino acid is very important. Cysteine ​​is an amino acid methionine can be found in many common foods, such as poultry, broccoli and yogurt, etc, so that the phenomenon on lacking of cysteine ​​is relatively rare.

When the human body has respiratory problems, the mucus will form in the lungs, while cysteine ​​can help break down those proteins in the mucus, and be able to effectively remove them. Cysteine ​​in the pancreas through oxidation to isolate from taurine, taurine is a kind of amino acids to help regulate the heart, and help the absorption of fat-soluble vitamins. The cysteine also helps the proper operation of the efficacy of the antioxidant glutathione. From glutathione manufacturer, we know that glutathione exists in all tissues of the body, which help protect against free radicals, plays an important role on the detoxification process. In addition to these effects, cysteine ​​also in the form of intravenous injection to prevent overdose of acetaminophen cause liver and kidney damage.

Cysteine ​​is a sulfur-containing amino acids naturally present in food, can also be obtained from the production of methionine in vivo. The process is methionine converted to S-adenosylmethionine, and then converted to homocysteine​​, homocysteine react with serine to form cysteine​​. High cysteine ​​content foods can help the body get rid of toxic chemicals and heavy metals, protecting cells from free radicals damage, eliminate the role of excess mucous membranes in lungs. Usually thought that frequent get colds people especially need to eat more cysteine​​-rich foods. Cysteine ​​food sources include poultry, yogurt, egg yolks, red peppers, garlic, onions, broccoli, cabbage, oats and wheat germ and so on.

As an important component of glutathione, cysteine have many important physiological functions such as promote anti-oxidation activity, glutathione is formed by cysteine​​, glutamic acid and glycine. It can be found in all human tissues, especially the liver and the eyes have the highest concentration. Glutathione is a potent antioxidant that can protect body tissues from free radicals damage. Glutathione antioxidant activity attributed to cysteine​​. Glutathione plays an important role in removing harmful substances such as heavy metals like lead, mercury and cadmium in the liver. Glutathione also can be used as cosmetic raw material, overall improve skin microcirculation, inhibit the activity of human melanoma cells. Its molecular weight is only 1/50 of collagen, it is possible to directly reach the basal layer of skin.

Lack cysteine ​​is relatively rare, but more common in the intake of methionine and cysteine​​-less vegetarian. ​​Lack cysteine has not any known health symptoms, but the lack of cysteine ​​may reduce the ability to prevent free radical damage, and may result in damage to the immune system function.

Cysteine ​poisoning symptoms, consume contain cysteine​​ foods, or early form of methionine is unlikely to cause symptoms of poisoning. However, it can cause susceptible populations brain cell damage. These people can not normal metabolism of amino acids, and therefore reduce the risk of suffering from multiple sclerosis and neurodegenerative diseases such as Alzheimer's.

Biotin metabolic absorption and physiological function

Biotin, also called vitamin H, coenzyme R. Biotin is a ureido ring containing a sulfur atom and one acid side chain, are known to have 8 isomers, naturally existing only alpha-biotin, and have biological activity. Biotin is colorless acicular crystal, easy to soluble in water, slightly soluble in cold water, soluble in ethanol, insoluble in organic solvents. With good thermal stability, general cooking loss is not big, strong acid, strong alkali and oxidant can destroy it, ultraviolet ray also can make it gradual destruction. Biotin mostly stored in the liver, contain lower levels in blood.

Metabolic absorption: biotin in food is mostly exist in free form or combined with proteins. Biotin binding with protein in the role of intestinal protease, form biocytin, then through the action of intestinal biotin enzyme, release free biotin. The main parts of biotin absorption is proximal small bowel. The low concentration is active absorbed by carrier transport; the high concentration is absorbed by simple diffusion form. The absorption biotin via portal circulation, transported to the liver, kidney internal storage, other cells also contain biotin, but less. Human intestinal bacteria can from two Pimelic acid instead of azelaic acid to synthetize biotin, but as the biotin direct source is not enough. The biotin in human body is mainly by the urinary excretion, milk also has a biotin discharge, but the quantity is very few.

Physiological function: the main function of biotin is playing a role in decarboxylation, coenzyme function carboxylation reaction and hydrogenation reaction, can transferred CO2 from one compound to another compound, so that a compound turn into another. Pharmacological doses of biotin can reduce type I diabetes blood sugar levels, improve the experimental rats glucose tolerance, insulin resistance. Biotin also can maintain various experimental animals’ immune cells to normal function.

Normal need: because of the gut bacteria can synthesize biotin, so it is not easy to accurately determine the biotin requirement. Adult daily intake is 30 micrograms, baby nurse daily intake is 35 micrograms; Excessive reaction: the biotin toxicity is very low, so far there is no biotin toxicity report.

Deficiency: researches by cosmetic raw material suppliers found that biotin deficiency is mainly appear skin symptoms, such as visible hair thinning, loss of luster, skin dry, scaly dermatitis, red rash, severe rash can distribute around the eyes, nose and mouth. In addition, accompanied by loss of appetite, nausea, vomiting, mucosal atrophy of tongue papillae, mucosa grey, numbness, depression, fatigue, myalgia, hypercholesterolemia and abnormal electroencephalogram. These symptoms occur in biotin deficiency after 10 weeks. Babies under 6 months of age can appear seborrheic dermatitis.

From biotin supplier we know biotin widely exists in food cheese, liver, kidney, cheese, soy, wheat, rice, strawberry, grape, grapefruit, beer, liver, eggs, lean meat, dairy products. People like to eat raw eggs and drinking wine and coffee need to add biotin; antibiotics or sulfa daily intake of at least 25 μ g; men with thinning hair intake of biotin, prevent hair loss effect is obvious; in pregnancy, biotin will loss quickly, should complement reasonable under the guidance of the physician.
