Vitamin C has always been one of the highly sought-after ingredients in cosmetics and cosmetology. In recent years, liposomal vitamin C has been attracting attention as a new vitamin C formulation. So, is liposomal vitamin C really better than regular vitamin C? Let’s take a closer look.
Vitamin C in Cosmetics
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin with many benefits for the skin.
Firstly, it is a powerful antioxidant that neutralises free radicals and protects skin cells from damage caused by oxidative stress.Secondly, Vitamin C inhibits melanin production, reduces discolouration and dullness, and brightens skin tone. It can reduce dopaquinone to dopa, thus blocking the melanin synthesis pathway.In addition, Vitamin C promotes collagen synthesis, enhancing the structure and elasticity of the skin, resulting in a fuller and smoother complexion.
Limitations of Common Vitamin C
Although Vitamin C has been shown to have significant benefits in cosmetic products, there are some limitations of regular Vitamin C.
Stability issues: Vitamin C is an unstable ingredient that is susceptible to oxidation and decomposition by light, temperature and oxygen.
Poor penetration: The large molecular size of common vitamin C makes it difficult to penetrate the stratum corneum of the skin and reach the deeper layers of the skin to do its job. Much of the vitamin C may remain on the surface of the skin and not be fully absorbed and utilised.
Irritation: High concentrations of regular vitamin C may cause skin irritation and discomfort such as redness and itching, especially for sensitive skin.
Advantages of Liposomal Vitamin C
Liposomal vitamin C is a form of vitamin C encapsulated in liposomal vesicles. Liposomes are tiny vesicles made up of phospholipid bilayers, which are structurally similar to cell membranes and have good biocompatibility and permeability.
Improve stability: Liposomes can protect vitamin C from the external environment and reduce the occurrence of oxidative decomposition, thus improving its stability and shelf life.
Enhanced permeability: Liposomes can carry vitamin C to penetrate the stratum corneum of the skin more easily and reach the deeper layers of the skin. Due to the similarity of liposomes to cell membranes, they can release vitamin C into the cell via intercellular pathways or by fusion with cell membranes, increasing the bioavailability of vitamin C.
Reduced irritation: Liposomal encapsulation allows for the slow release of vitamin C. This reduces the direct irritation to the skin caused by high levels of vitamin C, making it more suitable for use on a variety of skin types, including sensitive skin.
Mechanism of action of liposomal vitamin C
When liposomal vitamin C is applied to the skin, the liposomal vesicles first come into contact with the skin surface. Due to the similarity between the lipid layer of the skin surface and liposomes, liposomes can be smoothly attached to the skin surface and gradually penetrate into the stratum corneum.
In the stratum corneum, liposomes may release vitamin C into the cellular interstitium through intercellular lipid channels or fusion with keratinocytes. With further penetration, liposomes may reach the basal layer of the epidermis and the dermis, delivering vitamin C into the skin cells.Once Vitamin C is inside the cells, it is able to exert its antioxidant, melanin-inhibiting and collagen-synthesising effects, thereby improving the quality and appearance of the skin.
Considerations for Choosing Liposomal Vitamin C Products
Although liposomal vitamin C offers many advantages, the following points should be noted when selecting related products:
Quality of liposomes: The quality of liposomes produced by different manufacturers may vary, affecting the encapsulation and release properties of vitamin C. The quality of liposomes may vary depending on the manufacturer.
Concentration of Vitamin C: Higher concentrations are not always better, and the right concentration will ensure effectiveness while reducing potential irritation and adverse reactions.
Synergistic nature of the formulation: Good quality products are often formulated with other beneficial ingredients such as Vitamin E and Hyaluronic Acid, which work synergistically with liposomal Vitamin C to enhance the overall skincare effect.
Liposomal vitamin C has significant advantages over regular vitamin C in terms of stability, penetration and irritation, and can be more effective in delivering the skincare benefits of vitamin C. However, this does not mean that regular vitamin C is worthless for consumers on a budget or who tolerate it well. However, this does not mean that regular vitamin C is worthless, and it is still an option for consumers who are on a budget or who tolerate regular vitamin C well.
