For newborns and babies (0-6 months), lecithin is usually used as an ingredient to help creams and lotions spread. Many people tolerate it, but babies’ skin is delicate and there are signs that some people can have allergic reactions and that products can sometimes be contaminated. Because of that, it is safer to be cautious with lecithin on infant skin.
If you use a product that lists lecithin on a baby under 6 months: choose products made for infants from reputable brands, avoid leave-on products with many active ingredients, do a small patch test on a tiny area of skin and wait 24–48 hours, avoid sprays or products that can be inhaled, stop use if you see redness, swelling, rash or breathing changes, and talk to your pediatrician before using if your baby has eczema or a family history of food or skin allergies. Prefer simpler formulas and products that state they test for contaminants.
Watch for signs of an allergic reaction (redness, rash, swelling, breathing problems) — allergic concerns are reported by clinical sources (Association of Occupational and Environmental Clinics and peer-reviewed case reports). Some safety reviews note lecithin can increase skin absorption of other ingredients (Cosmetic Ingredient Review). There are also reported contamination risks, including nitrosamines; choose products from companies that test for contaminants. If your baby has known egg or soy allergies, check the lecithin source and avoid it if it comes from those ingredients.
