Ingredient review
Cornmint Powder
INCI: Mentha Arvensis Powder
Cornmint powder adds a cooling feel and light minty scent to products, but its high menthol content can irritate sensitive skin.
In plain English
Cornmint powder is made from dried and ground leaves of a mint plant called Mentha arvensis. In skincare, it gives a refreshing, cooling sensation when applied, similar to peppermint. It also has a natural minty smell and may help reduce minor skin irritation due to its mild antimicrobial properties. However, because it contains menthol, it can cause stinging or redness on sensitive or broken skin.

What it is
A finely ground powder from the dried leaves of Mentha arvensis, a mint species commonly known as cornmint or field mint. It is rich in menthol, menthone, and other volatile oils.
How it works
When applied to the skin, the menthol in cornmint powder activates cold-sensitive TRPM8 receptors, creating a cooling sensation. Its volatile oils also provide a mild antimicrobial effect, which can help reduce surface bacteria. In formulations, it acts as a natural exfoliant in scrubs and adds a refreshing sensory experience.
Pros
Natural cooling effect
The menthol in cornmint powder triggers a refreshing, cooling sensation on the skin, which can feel invigorating in cleansers or masks.
Mild antimicrobial support
Its volatile oils offer gentle antimicrobial activity, which may help keep the skin's surface cleaner when used in rinse-off products.
Cons and cautions
Potential for irritation
The high menthol content can cause stinging, redness, or burning, especially on sensitive or compromised skin, limiting its suitability for many users.
Sensory overstimulation
The strong cooling and minty sensation may be overwhelming or unpleasant for those who prefer fragrance-free or neutral-feeling products.
Best for
- People who enjoy a cooling, tingling sensation in their skincare routine

Use caution if
- Individuals with sensitive, rosacea-prone, or eczema-prone skin
