Some moisturizer can cause quite a bit of shine, some products actually use it as a benefit, saying it gives a more radiant skin tone. If you want to go for something shine free, look for a moisturizer that says "shine free" or "shine control" on the bottle, there are plenty out there that are good! I know clean and clear has a shine control moisturizer, and it works quite well. Just keep your eyes open, or ask someone at the make up counter at your local drug store, there is plenty of options!

Hope this helps (:

A huge discovery I found is that most petrolatum based lotions are shine free, while the lighter "fluffier" lotions leave shine.
