Please advice me on how to use these two gel for my acne

Patient: I’m taking treatments for my pimples and I use Adapalene gel for my acne and Neotone cream for dark spots as told. Both have to use at night. I usually apply Adapalene at night and sleep then wash it off in the morning. Now I have the Neotone cream for dark spots as well. How can I use both of them at night ?I was asked to apply both of them together at night but i prefer to get advice on this before doing that.
