Skin bioengineering studies have shown the durational effect of the emollient (skin smoothing) action produced by lanolin is very significant and lasts for many hours. Lanolin applied to the skin at 2 mg/cm2 has been shown to reduce roughness by about 35% after one hour and 50% after two hours, with the overall effect lasting for considerably more than eight hours. Lanolin is also known to form semiocclusive (breathable) films on the skin. When applied daily at around 4 mg/cm2 for five consecutive days, the positive moisturising effects of lanolin were detectable until 72 hours after final application. Lanolin may achieve some of its moisturising effects by forming a secondary moisture reservoir within the skin.
