From the Research
Yes, lanolin can cause itching in some individuals, with a reported frequency of contact allergy to lanolin of 0.4% in the European population. Lanolin is a complex mixture of high molecular weight esters, aliphatic alcohols, sterols, fatty acids, and hydrocarbons that has been widely used for centuries for its emollient properties 1. The most recent and highest quality study, published in 2022, found that lanolin is an important cause of allergic contact dermatitis, with a prevalence of 4.63% between 2011 and 2018 2.
Key Points to Consider
- Lanolin allergy is more common in certain populations, such as children and the elderly, and in individuals with certain comorbidities, such as atopic dermatitis and stasis dermatitis/leg ulcers 1.
- The allergic reaction to lanolin occurs because the immune system identifies certain proteins in lanolin as harmful substances and releases histamine and other inflammatory chemicals, resulting in the itching sensation.
- If symptoms persist or are severe, it is recommended to consult a healthcare provider who may recommend antihistamines or topical corticosteroids to manage the reaction.
- Consider switching to lanolin-free alternatives such as petroleum jelly, shea butter, or plant-based oils if you experience itching after using lanolin-containing products.
Management and Prevention
- Discontinue use of lanolin-containing products immediately if itching occurs and wash the area with mild soap and water.
- Be aware of the potential for lanolin allergy, especially in high-risk populations, and take steps to prevent exposure.
- Consult a healthcare provider for proper diagnosis and management of lanolin allergy.
