Liposome Technology
Liposomes were originally used in medicine to aid the penetration of injected drugs, so their use in skin creams had contentious beginnings. Microscopic, lipid spheres (Soya oil and ceramide are common ingredients), these hollow carrier molecules can be tilled with other skin-care ingredients, which are then delivered to target sites in the skin.
Early cosmetic liposomes were deemed unstable and useless nothing more than oily lubricants that melted on the skins surface. Alter countless refinements, however, it does seem that the liposomes of today - newer, tinier and more stable molecules can access the lower layers of the epidermis. Most skin creams contain them.
Does skin breathe? Oxygen is the key to healthy cell regeneration and skin metabolism. Medical opinion is that skin cells receive oxygen via the bloodstream and not through the pores of the skin. An increasing number of cosmetologists, however, suggest that oxygen can be introduced into the skin via specially constructed liposomes.
Sceptics hold that too much oxygen generates free radicals. Champions assert that oxygen creams arc like a breath of fresh air to dull skin (especially smoker's skin) with poor circulation. The skin aerobic debate is set to continue for many years to come.
