Over the last two years my best results have come from the following skin care routine:
Staying well hydrated
Changing regularly
Washing at each change with warm water (no soap)
Using Johnson and Johnson's bedtime lotion at each change
Showering daily and using shampoo as the primary soap
Each person is different, activity levels, body chemistry and incontinence varies. This has worked for me. The bedtime lotion is water soluble and it seems to do a good job of keeping my skin from being irritated from the urine. Irritations from garments rubbing have given me some problems. Usually these occur when I have not changed frequently enough. Changing brands of protection, using Vaseline on irritated spots early helps.
