Ingredient review
Menthone
INCI: Menthone
Menthone provides a cooling, minty feel in skincare but can be irritating for sensitive skin at higher concentrations.
In plain English
Menthone is a natural compound that gives peppermint its refreshing, cooling sensation. In skincare, it's added to products like cleansers and lotions to create a tingly, invigorating feel on the skin. It also has some mild antimicrobial properties, meaning it can help reduce certain bacteria on the skin's surface. However, because it can be slightly irritating, it's not ideal for very sensitive or damaged skin.

Quick decision guide
Useful, but context matters
Menthone can be useful, but watch for some irritation potential.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Menthone.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk

What it is
Menthone is a naturally occurring organic compound classified as a monoterpene ketone. It is a major constituent of peppermint oil and is responsible for the characteristic minty aroma and cooling sensation.
How it works
Menthone interacts with cold-sensitive TRPM8 receptors in the skin, triggering a cooling sensation without actually lowering skin temperature. It also has mild antimicrobial activity, which can help reduce surface bacteria when used in cleansers or toners.
Pros
Cooling sensation
Menthone activates cold receptors in the skin, providing a pleasant, invigorating tingle that many people find refreshing, especially in cleansers and toners.
Mild antimicrobial action
Studies show menthone has some ability to inhibit the growth of certain bacteria on the skin, which can be a bonus in products aimed at reducing surface impurities.
Cons and cautions
Potential for irritation
At higher concentrations or on sensitive skin, menthone can cause stinging, redness, or discomfort, making it unsuitable for those with reactive skin conditions.
Limited skincare benefits
Beyond its cooling and fragrance roles, menthone offers no proven moisturizing, anti-aging, or barrier-repair benefits, so it's more of a sensory additive than a functional active.
Best for
- People who enjoy a cooling, tingly sensation in their skincare routine
- Those with normal to oily skin looking for a refreshing cleanser or toner
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
Usage tips
Safety summary
Menthone is considered safe for most skin types at typical cosmetic concentrations. However, it can cause irritation in sensitive individuals or when used on compromised skin. Patch testing is recommended for those with a history of fragrance sensitivity.
Research notes
Research on menthone primarily focuses on its sensory effects (cooling via TRPM8 receptors) and antimicrobial activity. Studies are limited but consistent with its traditional use in mint-based products. More robust clinical trials on cosmetic efficacy are lacking.
Common label clues
- Typical concentration
- Typically 0.1% to 1% in leave-on products
- Regulatory status
- Menthone is generally recognized as safe (GRAS) by the U.S. FDA for use in food and is approved as a fragrance ingredient in cosmetics by the International Fragrance Association (IFRA).
- Common uses
- Facial cleansers, Toners, Body lotions, Lip balms
- Environmental note
- Menthone is naturally derived from peppermint plants, which are widely cultivated and considered a renewable resource. No significant environmental concerns are associated with its production.
Good to know
- Menthone is often found alongside menthol in peppermint oil, but it is less potent and less irritating than menthol.
- On ingredient labels, menthone may be listed simply as 'Menthone' or as part of 'Peppermint Oil'.
