Lanolin

Description

Lanolin is a natural, waxy substance derived from sheep's wool, renowned for its exceptional moisturizing and emollient properties. This versatile ingredient has been used in skincare and cosmetic formulations for decades due to its ability to mimic human sebum. Lanolin's molecular structure allows it to form a semi-occlusive barrier on the skin, effectively preventing transepidermal water loss while still allowing the skin to breathe.

Rich in cholesterol and fatty acids, lanolin helps to repair and protect the skin's natural barrier function. It is particularly effective in treating dry, chapped, or irritated skin conditions. Lanolin's unique composition enables it to absorb up to 200% of its weight in water, making it an excellent humectant that draws moisture to the skin and keeps it hydrated for extended periods.

While lanolin is generally well-tolerated, some individuals may experience allergic reactions. Modern purification processes have significantly reduced the risk of allergens, resulting in medical-grade lanolin suitable for sensitive skin. Lanolin is commonly found in lip balms, hand creams, nipple ointments for nursing mothers, and various other skincare products designed to provide intense hydration and protection.
