Description

Menthol needs no introduction: it's the thing that causes thecooling sensation so well-known both from cosmetic products as well as a bunch of other things like chocolate, chewing gum, toothpaste or cigarette. It's a natural compound that comes from the essential oil of Mentha species (peppermint oil contains 40-50% menthol) and it gives them their typical minty smell and flavor.

As for skincare, menthol seems to be a mixed bag. Apart from the cool cooling sensation (that might last up to 70 mins!), it also has painkilling, itch reducing, antibacterial, antifungal and even penetration enhancing properties. On the other hand, it also seems to act as a skin irritant that increases trans-epidermal water loss (the water that evaporates from the outer layer of the skin) and thus contributes to drying out the skin.

Frequently Asked Questions about Menthol

What does menthol do in skincare products?
Menthol gives a cooling sensation on the skin by activating cold-sensitive receptors, which can make a product feel refreshing. It is often used in lotions, gels, aftershaves, and acne or muscle rubs for that tingly effect. It does not actually lower skin temperature, even though it feels that way.
Is menthol good for irritated or itchy skin?
Menthol can temporarily distract from itch or mild discomfort because of its cooling, sensory effect. That said, it can also sting or irritate sensitive, broken, or overexposed skin, especially at higher concentrations. People with very reactive skin should be cautious with menthol-containing products.
Can menthol help with a stuffy nose or a cold?
Menthol can make breathing feel easier by creating a cooling sensation in the nose and airways, but it does not clear congestion or treat the underlying cold. Products like rubs, inhalers, or lozenges may provide subjective relief, especially for adults. It should not be relied on as a medical treatment for nasal blockage or infection.
Is menthol safe to use on the skin?
Menthol is generally safe in cosmetic products when used at appropriate levels, but it can cause irritation, redness, or a burning feeling in some people. The risk is higher on damaged skin, near the eyes, or when used too often. If a product causes strong discomfort, it should be washed off and avoided in the future.
Why do some people choose menthol in hair or scalp products?
Menthol is added to some hair and scalp products because it creates a fresh, cooling sensation that can make the scalp feel cleaner or less itchy. This feeling does not mean it stimulates hair growth, and evidence for that claim is limited. In sensitive scalps, it can sometimes cause dryness or irritation instead of comfort.
