Organic Peppermint Essential Oil.
Everything you need to know about this ingredient in lip care.
What it is.
Peppermint essential oil (Mentha piperita) is extracted from organic peppermint leaves through steam distillation. Known for its refreshing, cooling sensation, peppermint oil contains natural menthol that gently stimulates circulation in the lips, creating a subtle plumping effect and a feeling of freshness. Beyond its sensory appeal, peppermint has documented antimicrobial properties and can help soothe minor lip irritation.
Scientific backing.
Research in the European Journal of Medical Research has confirmed peppermint oil's antimicrobial activity against a range of common pathogens. A study in the International Journal of Neuroscience found that peppermint aroma enhanced alertness and cognitive performance. The menthol in peppermint has been shown in dermatological studies to mildly increase local blood flow when applied topically, which can contribute to a natural, subtle lip-plumping effect.
