On the production description, it says water-based primer, oil-, silicone- and fragrance-free, control shines for sensitive, oily or problem-prone skin.
It received some pretty bad reviews on MUA, a lot of reviews said...
It flakes/peels off
This doesn't happen to me (I tried rubbing my face to see if I'd find any flakes - nothing). I only use one pump of product. I spread the primer evenly all over and massage my face and pat it gently until the primer is dry. I let it sit for 1-2 mins before applying the liquid foundation (I use MUFE HD Foundation).
It does have this slightly weird smell but not strong. You know how fragrance-free products can a smell a little weird sometimes? That's the only words I can describe the scent.
Does it do what it says?
Yes and no. The primer is colourless with light texture. It doesn't break me out. My foundation does go on smoothly. My makeup lasts longer, espcially the concealer. As for oil control, it does help a little but I don't see a big difference (I've combination skin with oily T-zone).
This is not a bad product but I can live without it.
