Placental Lipids

Placental lipids are fat-soluble compounds extracted from placental tissue. They contain a mixture of naturally occurring lipids—including cholesterol, fatty acids, and other membrane components—that mirror some of the structural elements found in healthy skin.In skincare formulations, placental lipids function primarily as emollients, helping to soften and smooth the skin surface by filling gaps between skin cells and reducing transepidermal water loss.

Placental lipids work through their emollient action. When applied to skin, they integrate into the stratum corneum (the outermost skin layer) and sit between skin cells, creating a hydrophobic barrier that slows water loss. This mechanism is straightforward physics rather than a targeted biochemical reaction—the lipids physically occupy space and impede evaporation.Because the lipid profile somewhat resembles components naturally present in skin, they may integrate reasonably well with existing skin lipids, though the extent to which they actively strengthen the barrier versus simply provi…

Placental lipids are typically found in moisturisers, serums, and creams rather than as standalone products. Use as directed on the product label—usually daily as part of your moisturising step. Apply to clean, damp skin to enhance hydration; they work well layered over hydrating toners or essences.

Placental lipids are generally well-tolerated and considered safe for cosmetic use. Those with specific ethical or religious concerns about placental-derived ingredients may prefer alternatives.
