Smash box primer? Any good?

[Joycey29]

Have had a few dodgy purchases recently but heard this was great - love my other Smashbox products but wondered if anyone had experience?
Don't really wear much make up but need a skin smoother for with BB and without....

It is a silicone based product so there are lots of cheaper versions with the same ingredients
For me it caused blackheads because it was too thick but they have a lighter version out now
Bourjois happy light mattifier was better for me and also cheaper. Definitely gives a smooth look.

I like it and I've tried the anti chafing gel that some say is very similar and found them to be very different.

That said, shu uemura under base mousse is in a different league to any other primer I've used and that's my all time favourite.

I use the green one before tinted moisturiser. It smooths over pores and lines nicely and reduces redness and shine effectively so I would give it a go. You can get tester tubes for about £12.

I am not sure I would use the green one as a standalone product, it does leave a bit of a Grotbags tinge. I imagine the other versions would be fine.

Which one would you suggest?
