I have been an advocate of lanolin for a long time. I think that it is a really effective treatment for dry skin. But it is a natural product, and natural products are prone to cause skin reactions. I think therefore that if you’ve got a seriously dry skin condition such as eczema you need to be careful when you try it, but if you can get on with it you will find it a very helpful material.
I’m a huge fan of lanolin as well. It’s one of the few non-plant-based ingredients I happily use. I have been ‘fooling around’ with a vegetable-based lanolin substitute over the past couple of years to see if it measures up to the real thing. So far lanolin wins, but I will continue trying it out.
