How does the shea butter in this cream help protect hands in cold, dry conditions?

Shea butter is a rich plant fat that works by creating a semi-occlusive film on the skin surface. This film slows down transepidermal water loss, which accelerates in low-humidity environments such as heated indoor spaces or freezing outdoor air. Unlike petroleum-based occlusives, shea butter absorbs with a drier finish, so hands don't feel greasy or slippery after application — useful if you handle paper, tools, or a keyboard shortly after.

In practice, the cream is most effective when applied while the skin is still slightly damp, for example within three minutes of rinsing and patting dry. This traps the maximum amount of water in the stratum corneum. Reapplication after each wash, before stepping outside, and before bed maintains a more stable barrier throughout the day. If your work involves repeated sanitiser use or hard water, a shea-based cream helps counteract the stripping effect of alcohol and mineral deposits.
