Hydrolyzed Phospholipids

Hydrolysed phospholipids are broken-down forms of phospholipids—fatty molecules that are fundamental components of cell membranes throughout the body, including the skin. These ingredients are created by breaking larger phospholipid structures into smaller fragments, which may allow them to be more readily absorbed and utilised by the skin.In skincare formulations, hydrolysed phospholipids function primarily as skin conditioning agents, helping to maintain skin's moisture content and support the structural integrity of the skin barrier.

The skin barrier is composed largely of lipids arranged in a layered structure. When this lipid composition becomes depleted—through age, environmental exposure, or certain skin conditions—barrier function can be compromised. Hydrolysed phospholipids provide raw materials to help replenish these lipid stores.Additionally, research suggests that phospholipid breakdown products (metabolites) may play a role in regulating immune cell behaviour and inflammatory responses within the skin, though the exact mechanisms in topical skincare remain an area of ongoing investigation.

Hydrolysed phospholipids are typically found in serums, moisturisers, and barrier-repair products. They work well alongside other skin-conditioning and barrier-supporting ingredients such as ceramides, glycerol, and niacinamide. Use as directed on the product label; there is no evidence that higher concentrations improve results. For sensitive or compromised skin, introduce gradually and observe for tolerance.

Hydrolysed phospholipids are generally well-tolerated and rarely trigger irritation. As with any ingredient, patch testing is advisable if you have highly reactive or sensitised skin.
