This works really well as a primer, I typically use on days where my skin looks particularly dull and tired.
Pop a little on my skin, focusing in the T-Zone, wait for it to sink in and then proceed with my foundation. Foundation applies so smoothly and glides over my pores instead of accentuating them. My base always lasts longer and looks better after using Beauty Flash Balm, give it a try!
I think my favourite thing about this product is that it isn't greasy. I have oily skin and Clarins Beauty Flash Balm Did exactly as it said without making me feel oily even under make up
Tips: You don't need a lot so don't go squeezing lots out of the tube the first time like I did
