Phospholipids are complex lipids that constitute one of the structural components of cell membranes.
In cosmetics, they are mainly extracted from soy or sunflower. Their presence in formulation serves a dual documented purpose: a role in skin comfort and a carrier role of interest in formulation. Their structure is amphiphilic: a hydrophilic head and two lipophilic tails.
This dual affinity allows them to organize into bilayers similar to those of cell membranes, a biomimetic organization documented in scientific literature for its contribution to skin comfort. By integrating into the lipid structures of the stratum corneum, phospholipids are associated, according to available data, with supporting skin comfort and preserving water comfort against external factors. This action contributes to skin that appears more supple, softer, and more comfortable daily.
Phospholipids are also documented for their ability to form liposomes, natural vesicular structures used as carriers in cosmetic formulation.
This role is linked in literature to better application of associated actives and their stability in formula. This is why phospholipids are frequently used as reference excipients in serums with high active concentrations. Their tolerance profile is well documented: they are suitable for all skin types, including sensitive or fragile skin.
In summary, an active ingredient of interest in cosmetics for its contribution to skin comfort, water comfort, and formula stability, for skin that appears more supple daily.
