Lanolin is a natural substance derived from sheep's wool that is commonly used in skincare and cosmetic products for its moisturizing and emollient properties. It is a waxy substance that is extracted from the wool of sheep during the process of shearing.

2. Use:

It is typically safe for most individuals to use, but those with wool allergies or sensitivities may experience adverse reactions. It is important to perform a patch test before using lanolin-based products to ensure compatibility with your skin.

Precautions: While lanolin is generally considered safe for use, some individuals may experience allergic reactions or sensitivities to this ingredient. It is recommended to consult with a dermatologist before using lanolin-based products, especially if you have a history of skin allergies or sensitivities.
