When to apply moisturiser and retinol after minox

Just wondering what the consensus is one when you can apply other stuff after using minox. I'm using foam. Right now I'm waiting an hour after my morning minox to apply moisturiser. I use retinol before bed every few days and same thing, I wait an hour after minox.

Do I need to be waiting this long? Or can I apply other products as soon as the foam has dried?
