Liposome C is Ascorbyl Palmitate in a Liposomal Delivery System (LDS).
Ascorbyl Palmitate is a oil soluble Vitamin C derivative, and can be easily formulated in skin care products. In order to achieve it's results, however, Vitamin C must penetrate the Corneocyte Layer to reach the target layers of skin. This is the purpose of the LDS.
Liposomal Delivery Systems are microscopic vesicles that consist of an aqueous center with a phospholipid membrane. Phospholipids contain a glycerol bonded to two fatty acids and a phosphate group with a polar head. The fatty acid portion of this bio-molecule is hydrophobic and is located toward the outside of the lipid bi-layer whereas the phosphate group is hydrophilic and faces the aqueous interior. These phospholipid walls are identical to those that comprise other human cell membranes. Liposomes can differ in size, with a range in diameter between 150 - 3500nm, and they can be found in unilamellar and multilamellar forms. Unilamellar vesicles are small, exceptionally stable, molecules as they are formed via a high shear processing method. The Ingredients To Die For Liposomes are the Unilamellar structure and offer high stability for the incorporation into personal care products.
Liposomes are hydrated bilayer structures that are readily compatible with the peridermal lipids (the skins primary moisture barrier) which exist as lamellar bilayers. Lamellar bilayers require less moisture to maintain their structure. When a Liposome fuses with the epidermal lipids, the epidermal lipid structure becomes overloaded with water and out of equilibrium. To restore equilibrium, the water and Phospholipid (+ the associated active) are rapidly churned throughout the top six cell layers of the stratum corneum, hydrating this structure. The extra moisture in the lipids remains for several hours, and greater penetration of the active occurs as it is rapidly carried down through the stratum corneum, with penetration stopping at the "end" of the living epidermal cells.
Ascorbic acid has several documented physiological and pharmacological effects on the skin. Ascorbic acid acts as an inhibitor of melanin formation and also plays a role in collagen formation. Unfortunately, ascorbic acid cannot be USEFULLY employed in any cosmetic product because of its incredibly poor stability. Therefore, Liposome C has been developed to offer formulators the benefits of a Vitamin C Active that can be delivered to the target layers, without the stability issues.
Vitamin C Actives have been widely used in various cosmetics and quasi-drugs because of their advantageous properties such as inhibitory effects on melanogenesis, promotion of collagen synthesis, and prevention of lipid peroxidation. The use of Ascorbyl Palmitate in cosmetics and cosmeceuticals is an important factor in preventing dry skin, sunburn, chloasma and ephelides, and in keeping the skin healthy and young.
Classic Anti-Wrinkle lotions utilize a Vitamin C active as their only anti-aging ingredient. Vitamin C is especially useful in anti-wrinkle and skin lightening formulae, and it's performance in these two arenas can be enhanced by coupling the Liposome C with Sodium Lactate and / or Lactic Acid in the formula. This combination has been shown to dramatically increase the reduction of hyper-pigmentation.
Vitamin C Actives are one of the best ingredients that we can use for anti-aging and anti-oxidant products, keeping in mind that Vitamin C is highly oxidative. While there are ways to formulate with Vitamin C, minimizing oxidation to keep it safe for cosmetics use, it is very challenging and failure to effectively stabilize Vitamin C will result in an unstable product that will be unstable and create free radicals. Of course, in personal care one of the main goals is to address free radical activity to minimize it and avoid the damage created as a result. With an encapsulation the Vitamin C is stabilized and the oxidation is no longer an issue. The added benefit is the delivery enhancement that you get with an encapsulation because the phospholipid used to encapsulate the active is a much smaller molecule which can penetrate the top, dead, layer of skin and deliver the active to the tissues where you can gain the benefits of the Vitamin C rather than having them reside in the dead layers until they are eliminated.
