For adults: lecithin is usually safe on the skin and is a common ingredient in lotions. Overall risk is low, but there are a few safety notes to keep in mind.
Do a small patch test on your inner forearm before using a new product. Avoid using products with lecithin on broken or irritated skin. If you have a soy or egg allergy, check where the lecithin comes from or avoid it. Prefer creams and lotions over sprays to reduce breathing in tiny particles. Buy from reputable brands and stop use if you see irritation.
Watch for signs of an allergic reaction (redness, hives, strong itching, swelling, breathing trouble) — allergy concerns are noted by clinical reviewers and case reports. Be aware some safety reviews flagged contamination risks (nitrosamines) and that lecithin can increase skin absorption of other ingredients (noted by cosmetic safety reviewers). Inhalation safety for spray products is not well studied. If you notice a reaction, stop use and seek medical care. Sources: safety reviews by cosmetic safety panels, clinical/allergy reports, and regulatory agency notes.
