Phospholipids are amphiphilic lipids (commonly derived from soy or egg lecithin) used in skincare to form liposomes, stabilize emulsions, and reinforce the skin barrier. They also enhance penetration and delivery of other actives.
| Reported effect | How often | Notes |
|---|---|---|
Mild transient irritation or stinging | Rare | Generally well tolerated; occasional irritation in sensitive skin. |
Allergic contact dermatitis | Rare | May relate to source material (e.g., soy or egg lecithin) or impurities. |
Oxidation-related sensitization | Very rare | Unsaturated phospholipids can oxidize, potentially yielding irritant by-products. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
