What happens after my handcream is sold?

It depends, is the short answer.

Many people use it on their hands, either before or after gardening or other activities that tend to dry out the hands. Others use it as a lip balm and one customer uses it on her feet because she finds it prevents her getting athletes foot.

This last is not surprising as many essential oils including geranium have a strong antifungal effect, though if making a cream specifically for that I would probably add one or two other oils.
