Lanolin is a natural wax-like substance that is derived from sheep's wool. It is a popular ingredient in skincare and personal care products due to its ability to provide hydration and protect the skin.

• Moisturizing: Lanolin is a highly effective moisturizer that can help to hydrate and soothe dry, rough skin. It contains natural emollients that can penetrate deep into the skin, helping to retain moisture and prevent dehydration.

• Protective: Lanolin forms a protective barrier on the skin's surface, helping to shield it from harsh environmental factors such as wind, cold temperatures, and pollution. This barrier can also help to prevent moisture loss, keeping the skin hydrated and healthy.

• Softening: Lanolin can help to soften and smooth rough, dry patches of skin, making it a popular ingredient in products designed to treat calluses and other areas of rough skin.

• Hypoallergenic: Lanolin is generally well-tolerated by most people, making it a good choice for those with sensitive skin. However, those with a wool allergy may be allergic to lanolin as well.

Overall, lanolin is a versatile and effective ingredient that can help to hydrate, protect, and soften the skin. It is commonly found in moisturizers, lip balms, and other skincare products.
