Let me just start off by saying that this foundation has seriously changed the game for me.
For my combination skin, this lasts all day, looks great throughout the day, is buildable, and makes my skin look flawless.
I use this foundation over top of my priming moisturizer by Glossier. There is a special brush that was designed for this foundation but I personally prefer using my beauty blender. I feel that it gives the foundation a more natural, even and well blended look.
And to finish it off and set the foundation I switch between MAC mineralize skinfinish in light and the RCMA no color powder, basically all depending on what type of finish and longevity I want it to have. RCMA for a more long lasting matte finish, and the MAC powder for a more luminous, additional coverage, with a little shorter of a lifespan than the RCMA.
If you are in need of a new foundation, I highly, HIGHLY recommend that you try this one out! Even with the price tag, this foundation is worth it.
Let me know what your ride or die foundation is!
