Lauromacrogols are chemical compounds that, when added to some moisturisers, are believed to possess anti-itch properties.
HelloSkin’s experts could not find any specific scientific data on the use of lauromacrogols in people with eczema. However, Lauromacrogols can function as local anaesthetics, and laboratory studies have shown they can inhibit the formation of new smaller blood vessels, which can reduce blood flow to a lesion and thereby minimise redness in the skin1. In people with dry and itchy scalp conditions, a leave-on combination product containing lauromacrogols (and other potentially active ingredients) applied to one half of the scalp 3 times per week for 4 weeks, was shown to reduce itching2.
However, in another study where different types of itching were experimentally induced in human volunteers, the lauromacrogols were only found effective itch-reducers in some, but not other types of itching3.
The concentration of an ingredient is important for its efficacy, and therefore products containing the same ingredient may not necessarily have the same effect as in the studies mentioned above.
