Lemon juice and blackheads

ive heard that lemon juice tightens your pores and helps get rid of blackheads but i also heard its used for bleaching hair or something like that, so would it be bad for you skin??? also how long would you keep it on? do you wash it off after 15 minutes?? Lemon juice and blackheads
yes it can help. its an astringent and antibacterial .but make sure you do it at night (you can leave it on all night and wash it off in the morning) you do not want to go outside with any trace of lemon on since the sun can cause severe damage this way.
