VA Liposome
Product Introduction
Liposomes are nano-sized particles resebling biomembranes and have a very high afhnity for the skin.They can easily penetrate through the hard horny layerof the skin. Based on this feature. active ingredients can be incorporated into iposomes to enhance their absortion by the skin and thus their efhcacy in facliposome-encapsulation largely reduces the amount of the active ingredient required for effectivess as compared to non-encapsulated, pure active ingredients
The difficulties of Retinyl Palmiate in cosmetic formulas:
● Retinyl Palmitate is kind of fat soluble vitamin and insoluble in water
● Retinyl Palmitate has high activity, but its activity is easily lost under light, temperature, oxygen and other conditions.
● Retinyl Palmitate with high concentration irritates the skin.
● Retinyl Palmitate is easy to turn yellow in products.
● Retinyl Palmitate does not penetrate the skin easily and has low bioavailability.


VA Liposome can improve skin penetration with the following benifits.
