Just that really.
Had a No7 matte skin primer for years, but have only just tried using it.
I really like my new foundation (YSL youth liberator) but the downside is, it doesn't last that long. Especially on my nose, so I got my primer out and it goes on fine, but when I then put my foundation over the top, it goes all blobby and my foundation doesn't go on well at all!
What am I doing wrong?
TIA
