Is applying multiple moisturizers effective?

Lately, my skin feels like it isn't getting enough hydration, so I've been reapplying moisturizer multiple times, but I'm not sure if this is the right way to do it. I've been trying to follow the advice that applying multiple layers is better than applying a large amount at once, but I can't really tell if there's a significant difference. In fact, if I apply too much, it feels stuffy and I think it might even cause breakouts. I'm wondering if other steps are more important than the cream for proper hydration. If anyone knows effective methods to address inner dryness, please share them!
