We here at Ingredients To Die For are proud to have much more than just a Vitamin C product, we offer our Liposome C. This product offers up to TWICE the activity of other Vitamin C products. The benefits do not stop there, Vitamin C is very unstable and prone to oxidation. Our Liposome C is highly stable due to the encapsulation.
Liposome C is Vitamin C in a Liposomal Delivery System (LDS).
What is Vitamin C?
Vitamin C is a water soluble vitamin C derivative, which is stable in aqueous solution, 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.
What is a liposome?
Liposomes 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 biomolecule is hydrophobic and is located toward the outside of the lipid bilayer 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.
Studies have shown that TWICE as much of the active is delivered to the living epidermis by an LDS when compared to topical application of the active alone.
What are the benefits of using a vitamin c active in skin care?
Vitamin C Actives have been widely used in various cosmetics and quasi-drugs because of its advantageous properties such as inhibitory effects on melanogenesis, promotion of collagen synthesis, and prevention of lipid peroxidation. The use of stable vitamin C 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 utilized 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 potentiated 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.
Suitable applications for Liposome C would include products geared toward improving:
- skin tone
- elasticity
- moisturization
- wrinkle reduction
- skin tightening
- absorption
- peeling skin conditions
- delivery system
- whitening
How do Liposomes Function?
Liposomes are hydrated bilayer structures that are readily compatible with the peridermal lipids (the skin's 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.
How does the performance of Liposome C compare to that of ascorbic acid?
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.
