Citrus limon peel oil is an essential oil extracted from the rind or peel of a lemon (Citrus limon). The essential oil is often produced from the leftover rinds after juicing.
The lemon essential oil is mainly comprised of limonene (up to 70%), as well as ß-pinene and terpinene, which combine to produce the specific lemon scent. This fresh, citrusy scent is the reason why it is used in skincare products as a fragrance.
People who have a sensitivity towards citrus fruits should be careful when using this oil, as it may cause a sun-induced skin rash.
