About this ingredient
Soy phospholipids (INCI: Soy Phospholipids) are soy-derived lipids, rich in lecithin and very close to those that build cell membranes and the skin barrier. In a formula they reinforce that barrier, help hold water and, thanks to their structure, improve the dispersion and delivery of other actives. As an active they play a solid supporting role. They add emolliency and comfort, useful on dry or barrier-compromised skin, though they are not a targeted treatment for wrinkles or dark spots. The evidence backs them more as a barrier conditioner than as a lead active. They can be used in pregnancy and breastfeeding: applied topically they carry no systemic significance. Tolerance is good, with low irritation and allergy potential. Comedogenicity is very low (1); oily or acne-prone skin may want to watch the response, though problems are rare. Anyone with a known soy allergy may prefer to avoid them.
