Will it make it look worse?

okay so girls as u know when u use some face washes it will make blemishes look worse the next day but then get better. Well tomorrow im going somewhere special with the boyfriend and i want my skin to look good, i will take a shower and use my usual face wash( OLAY- blemish control, lathering cleanser) sometimes that will make it look worse but sometimes not so i dont know if i should use it tonight or not cause i do know we will be taking pictures tomorrow and id like to look my best, but i have this facial stuff (meaningful beauty by cindy crawford, the masque) and i have never used it before so if u use either of these products or know something about them let me know if i should use them tonight cause again i do wanna look good tomorroww,thanks(:
