Lemons grow on trees in the rue family or Rutaceae. The characteristic scent of lemon comes from the odor molecules in the peel. The fragrance molecules of citrus fruits are very volatile, meaning they are one of the first ingredients that fades away in a perfume. That is why citrus is often used in the top of a perfume, also often in the combination with pepper or vetiver to make the fresh character in a perfume that lasts longer.

• Since citrus molecules are very volatile, perfumes that contain a lot of citrus fruits are best stored in the fridge, like Smile & Shine from The Zoo (which contains 3 types of Italian citrus fruits).
• In addition to the smell of the lemon peel and fruit, the leaves of the tree also spread a wonderfully aromatic scent. These leaves can be found in perfumes, but also in dishes, they give a slightly bitter-sour but especially aromatic taste.
