Popular in a wide range of products, lemon is astringent, cleansing and brightening for the skin. It's also energizing and can help you to focus, which makes it a great pick-me-up.
Citrus limonum is a thorny, evergreen tree with irregular branches bearing shiny oval leaves. It produces white, pink-tinged strongly perfumed flowers, which turn into berries - the lemon fruit. Lemon oil is extracted from the rind by cold expression - it takes up to 3000 lemons to produce just over 2lbs of this pale, yellow-green essential oil.
