I have been working on finding an approved make-up look for dates. Matia said that I could use Loreal mascara.  I like Beauty Tubes because it looks like I am wearing extensions LOL.  Matia hadn't noticed a correlation between mascara and IC pain.  Maybelline Eyestudio is an amazing eyeliner that actually lasts all day.  The eyestudio eye shadows are amazing as well.  They sparkle and last all day.  I have oily skin and am impressed at the staying power of maybelline's eye make-up.  For blush and lipstick, I have been using Covergirl because of its pigmentation and staying power.
  Of course natural make-up is way better for you.  If you can afford it, I would definitely reccomend using the  natural make-up suggested by others on this site.  http://www.makeupalley.com/ is a great resource as well.
   Feel free to share any beauty tips that you have picked up along the way :o)
