Liposomes have attracted interests in cosmetic industry but there are few liposome products on this market. One of the reasons is their structural instability during long-term storage. There are many published studies on the effects of liposomes on percutaneous absorption. However, due to varying experimental conditions, no positive conclusion can be reached regarding their effects. We show important factors affecting liposomal stability and examine the percutaneous absorption of these liposomes, and demonstrate their topical effects on the skin.
