March Birchbox: Opening and Contents

Hello lovelies! The internet has been slow as of late and wouldn't allow me to post, but I received my March Birchbox in the mail the other day.  It was just the thing I needed to make my day better, makeup can fix anything! Here's what I received:

I loved the picture on the card this month because it's very Spring-y and that's all I am hoping for is a warm spring and a warm summer.

Seventh Generation Clearing Skin Serum

In every makeup blog I've read, the lovely blogger always uses some sort of serum on their face at night.  I had never used serum because I was afraid that it would clog my pores or make my face even more oily.  I got this at Wallgreens about a week ago and I've been using it nightly after I wash and tone my face.  I haven't noticed it helping to clear my face, but I have noticed my skin feeling a bit better.  It makes my skin feel a bit softer and not so dry, especially since it is becoming winter that is definitely something I worry about.  I also don't have to use as much lotion during the day because the serum absorbs and stays but doesn't clog my pores, which is really nice.
Do you guys use any serums on your face?  What have you found works best for you? XOXO
