What it is
Peppermint leaf extract is a natural plant extract obtained from the leaves of Mentha piperita. It contains compounds like menthol and menthone that give it a characteristic cooling sensation and minty aroma.
How it works
When applied to the skin, menthol in peppermint extract activates cold-sensitive receptors (TRPM8), creating a cooling sensation without actually lowering skin temperature. This can temporarily soothe minor discomfort and give a refreshed feeling.
Pros
Cooling sensation
The menthol in peppermint extract creates a pleasant cooling effect on the skin, which can feel refreshing and invigorating, especially in cleansers or masks.
Natural origin
Derived from the peppermint plant, this extract appeals to those seeking plant-based ingredients in their skincare products.
Cons and cautions
Potential irritation
Peppermint extract can cause stinging, redness, or irritation, particularly on sensitive or damaged skin, due to its menthol content.
Limited functional benefits
Beyond its cooling effect and mild antimicrobial properties, peppermint extract doesn't offer significant moisturizing, anti-aging, or barrier-supporting benefits.
Best for
- People with normal or oily skin who enjoy a cooling, invigorating feel
- Those looking for a natural minty fragrance in their skincare routine
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
