I've worked in engineering for over 30 years and have used numerous barrier creams which help to stop contaminates damaging your hands and also stop them drying out and chapping. It's not always practical to wear gloves for some tasks.
I've never bothered when I'm gardening but would think the same products would work, certainly makes it easier to clean your hands at the end of the day.
One of the best is Stokoderm, not cheap but very good.
