Lanolin in Eyelid Ointments: Benefits and Allergy Risk

Nizam Diveli

By Nizam Diveli, registered optometrist and founder of BlinkBetter

Lanolin is a rich, waxy substance from sheep's wool that holds moisture in the skin. In eyelid ointments it helps soothe and protect dry, sore lid edges, especially overnight. True lanolin allergy is uncommon but real, so it's worth knowing who should take care.

What is it?

Lanolin is a natural wax produced by sheep to protect their wool, purified for use in skincare and medical products. It's an occlusive emollient: it forms a soft protective layer that slows water loss from the skin, and it blends well with petrolatum and plant butters.

What does the evidence say?

Lanolin has been used for decades on dry, cracked skin. Its main question mark has always been allergy. A large London patch-test study of over 24,000 people with skin problems found a mean annual sensitivity rate of about 1.7%, and concluded that sensitisation stayed relatively low and constant even in a high-risk group (Wakelin et al., British Journal of Dermatology). Allergy is more likely in people with damaged skin, such as leg ulcers or eczema.

Is it safe around the eyes?

  • Most people tolerate lanolin well.
  • If you've reacted to lanolin, wool alcohols, or creams containing them, avoid it.
  • Apply a small amount to the lid edges, not into the eye. Ointments can blur vision briefly, so they're best used at night.
  • Stop if you notice itching, redness or swelling of the lids.
