Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Lanolin is a natural, waxy substance derived from sheep's wool and is widely used in dermatology and skincare products. Its primary function is as an emollient, meaning it helps soften and moisturize the skin. There is scientific support for its use in relieving itching, particularly when the itch is due to dry, cracked, or irritated skin. Lanolin forms an occlusive barrier on the skin's surface, reducing transepidermal water loss and promoting skin hydration. This barrier function can help soothe and reduce itching associated with xerosis (dry skin) and some forms of dermatitis.

However, while lanolin is effective at improving skin hydration and, by extension, can help alleviate pruritus (itching) associated with dryness, the direct evidence for its anti-itch properties is limited compared to other active ingredients specifically formulated for pruritus (such as topical corticosteroids or antihistamines). Most clinical support for lanolin’s use comes from studies and reviews on its emollient and barrier-repair properties.

In addition, lanolin may cause allergic reactions in a minority of users, especially those with sensitive skin or pre-existing dermatitis, which can actually worsen itching in those individuals.

In summary, the use of lanolin for itching is scientifically justified primarily through its moisturizing and protective effects on the skin barrier, but the evidence directly linking it to anti-itch efficacy is limited, meriting a moderate-low rating of 2 on the evidence scale.
