Lemon Oil description

Commonly used citrus oil that can be a skin sensitizer, especially on abraded skin. Lemon oil has limited research proving any benefits for skin. As with many fragrant oils, lemon oil has antioxidant components that can be beneficial, but there’s no valid reason to tolerate the bad to get the good. Lemon oil contains numerous fragrance chemicals that can cause a reaction when on skin that’s subsequently exposed to sunlight. Examples of the fragrance chemicals in lemon oil include limonene, bergapten, and oxypeucedanin. Although it smells great, fragrance is not skincare! The major fragrance chemical in lemon oil is limonene.
