Is it good to use tretinoin cream with aloe vera gel? Also, which should be applied first?

I have been using tretinoin cream for a few weeks now. I would always put aloe vera gel on my face first and wait at least 20 mins before putting on the cream. So far, I have not experienced any irritating side effects such as redness, flaky skin, and breakouts. Is it because of the aloe vera gel? Maybe it lessens the effects (good and bad) of the cream or it dillutes it? Would it be better to use the cream first before the gel? Thanks a lot in advance! All the best!
