A terpenoid from peppermint. Activates TRPM8 cold receptors, producing a cooling sensation. Used in after-shave balms, foot products, and shampoos. Does not treat the skin – provides a sensory effect perceived as 'freshening' or 'toning'. Irritation and contact dermatitis are possible, especially above 1%.
Topical application
CWeak evidence. In vitro data, open-label studies, or expert consensus.
The TRPM8 sensory activation effect is established. No clinically significant therapeutic skin effect. Concentrations above 1% are associated with irritation and contact sensitisation. Restricted in leave-on products under IFRA guidelines.
Menthol is a monoterpene alcohol, the main component of peppermint essential oil. In cosmetics used as a cooling, analgesic, and aromatic component. Mechanism. Activates cold TRPM8 receptors in skin nerve endings – produces a cool sensation without actual temperature drop (Bandell 2007). This temporarily distracts from itch and pain. Causes dilation of superficial vessels. Where applied. Shampoos and conditioners (cool scalp sensation), oily-skin scrubs and toners, foot gels, after-sun products, anti-itch products for eczema and insect bites. Concentration 0.1–3% leave-on, up to 10% rinse-off. Evidence base. Bromm 1995 RCT showed reduced itch in patients with eczema and senile xerosis at 1% menthol. AAD 2024 mentions menthol as a symptomatic anti-pruritic agent in the absence of active inflammation. Safety. CIR confirmed safety up to 3%. In 5–15% of patients it causes irritation, burning, contact dermatitis – especially on damaged and atopic skin. Do not apply to face in children under 2 years – risk of reflex apnea on nasal mucosal contact. Permissible concentration in children's cosmetics (over 2 years) – up to 0.5%. Pregnancy and lactation – use with caution. Topical use at cosmetic concentrations (up to 1%) is acceptable. Avoid application on abdomen, breast, nipples. In lactation do not apply to breast – may reduce lactation (anecdotal data).
