Lanolin
Lanolin is a rich, waxy substance naturally produced by sheep to protect their wool and skin. In beauty products it acts as an extremely effective emollient and occlusive, helping to lock in moisture and soften dry or chapped areas. You will often find it in lip balms, hand creams, nipple creams and barrier ointments.
How it works in skincare
In cosmetics and skincare, lanolin works by forming a semi-permeable layer on the skin that reduces transepidermal water loss while still allowing the skin to breathe. Its unique composition of sterols, fatty acids and esters closely resembles human sebum, enabling it to penetrate the upper layers of the skin and deliver long-lasting softness and protection. British formulators prize it for its ability to soothe and repair very dry, rough or cracked skin without leaving a heavy or greasy film.

Where it comes from
Lanolin is a natural wax secreted by the sebaceous glands of sheep. It is gently extracted from the wool after shearing, refined and purified for use in cosmetics.
