For adults, vanillin (a vanilla scent) is usually safe when used on skin in normal amounts. Most people tolerate it fine, but it can cause allergic skin reactions in some.
If you want to use a product with vanillin: do a small patch test on your inner forearm and wait 24–48 hours. Stop use if you get redness, itching, swelling, or a rash. Avoid applying it to broken, inflamed, or raw skin. If you have known fragrance allergies or very sensitive skin, choose fragrance-free products instead.
Watch for allergic reactions (redness, itching, hives). This concern comes from regulatory safety listings that identify vanillin as a known or possible skin allergen (EU Cosmetics Directive) and from agency reports noting limited evidence of skin irritation (European Chemicals Agency). Also note that some product certification programs restrict use of vanillin without proper documentation; check product labels if you prefer certified fragrance-free items.
