Lemon (Citrus lemon) EO is an oil I should use more often. Not sure why I don’t as I love the fresh crisp scent that it has. The EO comes from the peel of the fruit and is obtained by the expression method. (https://lazycatoils.wordpress.com/2013/04/27/how-is-an-essential-oil-made/) It belongs to the Rutaceae botanical family along with all of the other familiar citrus fruits like oranges and limes.
Among its many benefits, lemon has antibacterial, antiviral, and astringent properties. It has a very uplifting scent and it always makes me smile when I smell it.
For the skin and hair, it can be helpful in reducing excess oil. It can also help restore dull looking skin to a more vibrant look by helping increase blood circulation. It is used to treat acne and oily skin. Many of the citrus oils are also photosensitive. Damage to the skin can be caused if the skin is exposed to sunlight after using oils like lemon. It is recommended to avoid sunlight for up to 24 hours after using some of the citrus EO. And of course, using any EO in a diluted form is always recommended.
