Did You Know? In fragrance, lemon provides a burst of freshness and a bright, energetic aroma, primarily as a top note. Lemon oil blends well with other citrus, floral, and woody notes, making it a versatile ingredient for colognes and summer scents. Lemon oil is derived primarily from its peel, which is cold-pressed to produce a zesty, clean, and bright essential oil. It embodies an explosion of freshness. The Mediterranean is a citrus paradise - in particular, Italy, Spain and Greece. Lemons thrive in subtropical and tropical climates.
