Lanolin

1. Function of Lanolin:

• Moisturizing: Lanolin is a natural emollient derived from sheep's wool, forming a barrier on the skin that locks in moisture. It helps treat dryness and promotes skin hydration.
• Skin Barrier Repair: Its lipid composition mimics human skin lipids, aiding in repairing and protecting the skin barrier.
• Wound Healing: Lanolin accelerates healing by keeping wounds moist and preventing scabbing, which can slow the healing process.
• Softening and Smoothing: It softens rough, chapped, or flaky skin, making it a popular ingredient for lips, heels, and elbows.

2. Applications of Lanolin:

• Moisturizers and Lotions: Provides long-lasting hydration for dry and sensitive skin.
