Detailed answer

Lanolin is a natural and highly effective ingredient in moisturizers. It acts as an emollient, which means it helps to smooth and soften the skin. Lanolin also has excellent moisturizing properties and helps in preventing water loss from the skin. It creates a protective barrier on the skin's surface, helping to lock in moisture and prevent dryness. Additionally, lanolin has a soothing effect on irritated or inflamed skin, making it suitable for individuals with dry, sensitive, or eczema-prone skin. However, it's important to note that lanolin can cause allergic reactions in some people, so individuals with known lanolin allergies should avoid products containing it.
