Ingredients Explained
This essential oil is steam-distilled from peppermint leaves, also known as peppermint oil. It's mainly used for scent in skincare but also provides that signature "cooling" sensation.
Peppermint oil is a "feels amazing" ingredient until it doesn't.
At higher doses or for those with sensitive skin, methol-type cooling can quickly turn into burning/irritation. It can also trigger irritant dermatitis or even allergic contact dermatitis. In a large patch-test dataset, peppermint oil had a low but positive rate for this.
In cosmetics, Cosmetic Safety Reviews (CIR) concludes that peppermint oil is safe to use when formulated to be non-sensitizing with some restrictions; for instance, pulegone, a naturally occurring component of peppermint oil, should not exceed 1%.
Since peppermint oil contains fragrance allergens such as limonene, linalool, and menthol, it can be sensitizing for those with rosacea, eczema, a broken skin barrier, or just sensitive skin in general.
In Japan, this ingredient is known as Hakka Yu.
