I recently bought an aloevera gel as my moisturiser but the 2nd time i use it, it seems like my cheeks are flaky after applying aloevera gel. It kinda seems like the flaky thing is just the aloevera gel because it disappears if i apply water on it. Is it okay to experience this?

I used to use rejuvenating sets for my routine but lately I've stopped using it since my skin is kinda sensitive that it turns red when I scratch it.

Starting today I've been using a salicylic acid cleanser by neutrogena for my new routine and I would like to hear your suggestions for my new routine. Lastly, Is it okay too to use an aloevera gel as a moisturiser after using cleanser?

I got my skin barrier damaged because of a rejuvenating set, would moisturisers be enough to help it heal?
