What is Lanolin?
I’m aware that some people dislike lanolin due to its smell. I’ve been fortunate to have access to unscented lanolin from my supplier. It has a slightly sticky texture which is especially noticeable in lip balms, so it’s important not to overdo it. The texture is flexible and seals in moisture, which I really appreciate. Naturally, it’s best to avoid using it in the summer, unless you’re going sailing.

Personal experience with lanolin often highlights its effectiveness as a deep moisturizer, particularly for very dry skin or in harsh climates. Its ability to form a protective barrier makes it especially useful in lip balms and hand creams.
Remember to patch test new products containing lanolin, especially if you have sensitive skin or wool allergies.
