When the external preparation for skin according to the present invention is applied to the skin, the glycerophospholipid, glyceroglycolipid, and sphingolinolipid-bonded complex of α-hydroxy acid, which is mixed as an active ingredient, has a lipid-soluble property due to the lipids. , Has a good affinity for the skin and shows a good transdermal absorption. Moreover, in the case of a lipid-bonded complex that exhibits amphipathic properties, it can be easily made into liposomes, so that it is easy to formulate it, and it can be applied to the skin for percutaneous absorption to more efficiently reach the dermis. You can Then, mainly in the dermis, fatty acid ester and phosphodiester bonds are hydrolyzed by enzymes such as phospholipase and phosphodiesterase in the skin, and separated into α-hydroxy acid and glycerophospholipid. α-Hydroxy acid acts on dermal fibroblasts to promote this proliferation and activate skin cells. On the other hand, glycerophospholipids and the like exert a moisturizing action and a cell activating action in the skin, and particularly prevent skin aging due to water loss of the skin.
