For babies aged 6–12 months (infants, little ones), farnesol is not highly toxic but can cause skin allergies or irritation. Because young skin is sensitive, there is a moderate chance a baby could get a rash or redness from products that contain it.
Prefer fragrance‑free products for your 6–12 month old. If a product lists farnesol or just ‘fragrance’ and you must use it, patch test on a small area first and use rinse‑off items rather than leave‑on creams near the face. Stop use right away if you see redness, swelling, itching, or a rash and talk to your pediatrician.
Watch for allergic or contact dermatitis reactions — this concern comes from European cosmetic rules and fragrance industry guidance (they list farnesol as a known or possible allergen). The European Chemicals Agency and other reviewers also report cases of skin reactions. Avoid products with farnesol on broken skin, avoid repeated use around the face, and be cautious with fragranced baby products.
