I have loved and used Shea Terra products for the last couple of years, so I was really happy to see them available through Birchbox. I've been using this like a toner, spraying it on my face after washing. It makes my skin feel refreshed and moist. I've only been using it a week, so I don't really know if it's building collagen, but it feels so great that I would want to use it even if it didn't. It smells so amazing that I swear it's mood enhancing aromatherapy that I'm spritzing on my face.
