I did a lot of research before buying this because it's pretty pricey at $30 a bottle. I heard a lot of rave reviews about it for oily skin so I pulled the trigger and am sooo glad I did. It keeps me matte for most of the day and my makeup doesn't melt off my face after a few hours. I can't say it's my HG primer yet because again, I've only used it for a few weeks, but if it continues to be this amazing, I don't see myself switching any time soon.
