Is it bad to use 2 moisturizers (one for day, other for night)?

Okay, so I wanted to use sephora's moisturizer for night time and then use Aveeno's spf 30 for day time (since aveeno's spf 30 is a uva/uvb protectant) I just wanted to know if this is a bad thing? Please&Thank you! I appreciate any answers, and please just positive answers that'll actually help me out!(:
