Liposomes

1 products

Liposomes are microscopic spheres built from a double layer of lipids, usually phospholipids such as lecithin, with a watery center. Because that structure mirrors the membrane of a living cell and the lipid arrangement of your skin surface, liposomes have been used since the 1980s as delivery vehicles in both pharmacy and cosmetics.Research on liposomal delivery is substantial. Studies show that liposomes improve the solubility and stability of ingredients that would otherwise degrade, that smaller vesicles improve skin hydration and distribute their cargo more evenly, and that liposome-carried molecules including collagen fragments and peptides reach the upper skin layers more readily than the same molecules applied plainly. Vesicle size, charge and composition all change the outcome, which is why not every liposomal claim means the same thing.Brands tend to describe liposomes as delivering actives deep into the skin. In cosmetics the honest ceiling is the upper layers of the epidermis, since a leave-on product is not meant to enter the bloodstream, and regulators would treat it very differently if it did. The realistic benefit is a more stable formula and a more even, comfortable delivery of the active it carries.Liposomal formats suit dry and barrier-compromised skin especially well, since the lipids themselves add something, and they suit anyone using a fragile active. They matter less if the ingredient is already stable and water soluble.They pair with any routine. Liposomal ceramide creams work particularly well as the final step over a serum, sealing in what came before while adding barrier lipids of their own.Ours carries ceramides in the Aestura AtoBarrier 365 Cream, a pharmacy-style cream for dry, reactive skin.
