Primer, some people swear by it, some dont see any difference to using it or not. Me? I like using one but its not make or break for me. I've used a whole barrage of primers and now I am onto Elf Studios Mineral Infused Face Primer. This completely reminds me of the GOSH Velvet Touch Primer but cheaper. I like it because is smooths my skin out filling fine lines and pores making a nice base for my foundation. Do I see everlasting results? In the heat my make up lasts longer than without it although I use this for the finish it gives my skin.
For the price, you should have this in your collection. Its a step closer to flawless skin.
