Penantin baby cream might help, it has zinc but also other ingredients as well.
As you may have seen me posting, cuz, ya know, I just can't say this enough.
Vitamine E ointment is faaaaB!!! Both for rashes and roids (the hemmer's not the ster's)
In Canada there's Webber's vite E ointment, first aid section of drugstore. ** Make sure it's an ointment and wear old undies.
Alternatively you can make your own with Vaseline and multi-sourced vite E caps, experiment, 1 -2 caps / table spoon of Vaseline.
For a rash, you might also want to try oatmeal baths too.
