you can also inform the doctor that you're going for PS soon, they will try their best to clear up your skin in time! Mine's next month and I'm so relieved now. :)
hihi, sorry for the late reply. mine was cleared within a month and they actually have a product that they prescribe you with that will force all the clogged pores to surface.. (breakouts) but it clears off very soon (2-3days), they will also give you something to apply to lighten any scars...
try niks clinic.. i've had a sudden outbreak of bad acne for a couple months.. after visiting niks and used their products, the acne cleared and the marks lightened too! worked pretty well for me n my gfs!
