Reasons to keep a hand cream handy at work:
Hands are a big deal - specifically, the appearance of well maintained hands. It's not about the manicure as much as it is about making sure that nails look groomed without having rough cuticles and that skin doesn't feel like sandpaper when you shake someone's hand at a meeting. Keeping hands smooth is simply another symptom to fellow co-workers that you are mindful about how you care for yourself, which translates (for them) as a signal that you are more thoughtful about your work.
Also, now that heels are more exposed at work with summer shoe styles - swipe some cream onto them to avoid the appearance of cracked skin. Cute and strappy do not look great if heels are crackly. Just sayin'.
Marlowe. No. 023 Hand Cream is an affordable great option ($5.99) and has a workplace friendly scent (read: not strong) that can work for any gender. It is not a super heavy cream, but has a nice lasting effect. FYI, for every Marlowe item sold, soap is distributed to people at risk for hygiene-related illnesses in partnership with Clean the World.®
So - the best reason is that it just feels good.
