Little Tiny Bumps

I've been using a new moisturizer (dove for sensitive skin that is fragrance-free, soap-free, pretty much everything-free) to heal my eczema. I'm noticed on my hands and arms little small bumps here and there. I put cortisod gel on them, but the bumps did not react to them. They look harmless (like the tip of a pen-width) but i'm wondering if the moisturizer is causing this. I also use cetaphil as my moisturizing lotion. My skin does not look dry at all either.
