I wear foundation everyday, but i have never use any primer or concealer for it, but my foundation did get a bit oily in the afternoon. i used to use finger in applying liquid foundation, it was alright from the beginning, but now i realized my skin doesn't really like it. can sponge be a good replacement and do i have to soak it in water first? the new foundation i am going to buy is very watery, will it soak up in sponge even more if i use it? please help!
