For newborns and babies up to 6 months, d‑limonene (a citrus scent) is best avoided on the skin. It can irritate delicate baby skin and can trigger allergic reactions.
Choose fragrance‑free products for infants. If you find a product with d‑limonene on the label and must use it, avoid applying it directly to your baby’s skin, do not use on broken or red skin, and rinse it off immediately if any redness, rash, or fussiness appears. Prefer plain moisturizers and products labeled for newborns.
Watch for skin redness, blotchy rash, swelling, persistent crying after application, or breathing changes — these can be signs of an allergic reaction. Sources for these warnings include regulatory findings that list d‑limonene as a possible allergen and cosmetics rules that require allergen labeling (for example, EU cosmetics regulations), contamination alerts noting formaldehyde risk, and animal studies showing developmental effects at high doses. If you see any of these signs, stop use and contact your pediatrician right away.
