Micro-encapsulated Vitamin C 20% – The Vitamin C Serum by PURE

Vitamins are a “necessity” in our daily skincare regimen. Its potency and efficiency of Vitamin C has been scientifically proven: antioxidant and free-radical scavenger and skin brightening effects. Probably, Vitamin C is the only scientifically proven antioxidant, making skin younger and brighter. Vitamin C has been widely employed for the treatment of wounds, burns, inflammation, irriration in the skincare industry.
However, vitamins are highly unstable – sensitive to light, temperature, oxidizing agents, pH and they are likely to interact with other ingredients. These factors may induce vitamins degradation, resulting in molecule inefficiency, discoloration, odor changes and even side effects, such as irritation. Furthermore, once it is degraded, Vitamin C itself becomes free radical, a poison. Thus, before we purchase Vitamin C products in the market, we have to look at whether C has been oxidated or degraded or became unstable. We have to watch out the most important fact: most of Vitamin C Serums in the market has lost its efficacy already when or even before they are placed onto the shelves. Their usual shelf life less than 21 days.

 

Stability of Vitamin C

Stability of Vitamin C

Stability of Vitamin C

As shown in the chart, traditional water-based and water-soluable L-ascobic acid (standard Vitamin C) serums in the market will lose 100% of efficacy within 14 days of the date of manufacture once it is blended with water.
In case that it is not blended with water (aqua), the Vitamin C serums will lose 50% of its efficacy within 14 days of date of manufacture, and 82% of efficacy within 45 days from the date of manufacture. Please look at the Chart.

 

 

Entrapment

In order to ensure vitamins efficiency and to increase product safety and shelf life, scientists have developed the application of micro-encapsulation technologies to Vitamin C Serum.
Our microcapsule shell enables optimal isolation of the vitamins, with no risk of diffusion. The vitamins are protected from the environment, light , temperature, pH, oxydation and cannot interact with other ingredients. As a result, the vitamins stability significantly increases, not only vs. naked vitamins. Thus, end product efficiency and shelf life are significantly improved, while using the micro encapsulated technologies. The vitamin C’s are released from the capsule by applying mechanical pressure, i.e by rubbing a cream or lotion onto the skin, until the moment of application, the vitamins remain fresh and potent, due to their high and improved stability.

 

Micro-encapsulation Technology in Liposomes

Scientists have invented a micro-encapsulation technology to preserve and enhance the stability of Vitamin C, in which Vitamin C is micro-encapsulated in liposomes. A liposome is a tiny bubble (vesicle), made out of the same material as a cell membrane.
Vitamin C Serum by Pure and box3Membranes are usually made of phospholipids, which are molecules that have a head group and a tail group. The head is attracted to water, and the tail, which is made of a long hydrocarbon chain, is repelled by water.
In nature, phospholipids are found in stable membranes composed of two layers (a bilayer). In the presence of water, the heads are attracted to water and line up to form a surface facing the water. The tails are repelled by water, and line up to form a surface away from the water. In a cell, one layer of heads faces outside of the cell, attracted to the water in the environment. Another layer of heads faces inside the cell, attracted by the water inside the cell. The hydrocarbon tails of one layer face the hydrocarbon tails of the other layer, and the combined structure forms a bilayer.
When membrane phospholipids are disrupted, they can reassemble themselves into tiny spheres, smaller than a normal cell, either as bilayers or monolayers. The bilayer structures are liposomes. The monolayer structures are called micelles.
The lipids in the plasma membrane are chiefly phospholipids like phosphatidylethanolamine and phosphatidylcholine. Phospholipids are amphiphilic with the hydrocarbon tail of the molecule being hydrophobic; its polar head hydrophilic. As the plasma membrane faces watery solutions on both sides, its phospholipids accommodate this by forming a phospholipid bilayer with the hydrophobic tails facing each other.
Liposomes can be composed of naturally-derived phospholipids with mixed lipid chains (like egg phosphatidylethanolamine), or of pure surfactant components like DOPE (dioleoylphosphatidylethanolamine). Liposomes, usually but not by definition, contain a core of aqueous solution; lipid spheres that contain no aqueous material are called micelles, however, reverse micelles can be made to encompass an aqueous environment.
Liposomes were first described by British haematologist Dr Alec D Bangham FRS in 1961 (published 1964), at the Babraham Institute, in Cambridge. They were discovered when Bangham and R. W. Horne were testing the institute’s new electron microscope by adding negative stain to dry phospholipids. The resemblance to the plasmalemma was obvious, and the microscope pictures served as the first real evidence for the cell membrane being a bilayer lipid structure.

 

Our formula in particular

Vitamin C Serum by Pure Anti Age SkincareThe scientists at our lab has created a formula called Brookosome™ ACE, where 20% Vitamin C are microencapsulated in a liposome with Vitamin A and Vitamin E. Retinyl Palmitate and Tocopheryl Acetate help to scavenge free radicals responsible for lipid peroxidation. Ascorbyl Palmitate at a rate of 20% works by helping to regenerate the Tocopherol (Vitamin E). All three vitamins are provided in the more stable ester form. In the skin the esterases present will hydrolyze the esters down to the active vitamins which will then play their protective role in the lipid membranes found in the epidermis.:
Vitamin C when applied topically to the skin can reduce both photo aging and chronological aging. Vitamin C is a major line of defence against reduced Collagen production and therefore is critical in the treatment of aging. As we age and Collagen levels are reduced, there is also a gradual reduction of Hyaluronic acid, the product needed for moisture retention. Vitamin C is also a Tyrosinase inhibitor, the enzyme that triggers the production of Melanin. The use of Vitamin C serum in your daily skin care regime and particularly when combined with gentle glycolic acid peels, is effective in reducing the appearance of unwanted pigment on the skin.

Ingredient List

Micro-encapsulated Vitamin C* 20% (with Vitamin A and Vitamin E), Polysilicone 15, C24-28 Alkyl Dimethicone, Squalene, Salicylic Acid, Glycolic Acid, Cyclomethicone, Natural essential oils, Benzylalcohol, Dehydroacetic Acid. * Ascorbyl palmitate is a fat-soluble ester form of vitamin C. Vitamin C in the form of Ascorbyl Palmitate is contained in a nanocapsule and is to be released from the capsule when you apply it to the skin and, when released, be converted to L-ascorbic acid. Vitamin C will be released into the skin when you actually apply the Serum to the skin. Until released, the efficacy of L-ascorbic acid is preserved “as is”. This technology is also called “Nanotechnolgies”.
