This is going too sound completely STUPID...
too be honest i think i have been applying my concealer the WRONG way.
how exactly and i supposed to apply it? rub it in and then apply my cover up?
Concealer and cover up are the same thing. Do you mean foundation? Cause if you do, you wanna dab it on, with a sponge or your finger. Don't rub it, just use a quick dabbing motion. And then you can apply your concealer.
do not rub! dab, with ur ring finger.apply one thats like creamy stick like Neutrogena Healthy Smoothing Stick or Clinique. apply it on undereyes, blemish. then dab with ring finger until perfectly blende in.; hope i helpeed :]
