What it is
Lemon extracts and oils are derived from the Lemon plant.
What it does
Lemon also has antibacterial properties.
In addition, it is a fragrance additive, thus used to impart a lemon scent to products.
Lemon can cause irritations. In addition, the use of cold pressed lemon oil is restricted in fragrances because it can have bad safe effects when skin is exposed to the sun rays, making it more susceptible to some damage.
