I am 21 years old. This year has by far been the worst one for me. For the first time in my life i had really bad breakout. I used to get ocassional one or two zits here or there. But this time my skin had red bumps which after sometime got pus in the middle. I was prescribed oral antibiotics and clindamycin and nicotinamide gel for those acne and later post inflammatory hyperpigmentation. My pimples went away after some time. But the pigmentation has lightened over 3 months but i know will still linger for minimum 1 year to fade away. But when finally things were looking great i had another breakout acne looked normal but were not reducing in size. So i again went to get those antibiotics and clindamycin and nicotinamide gel and applied it on my acne. Acne reduced in size but till yesterday i had no inflammation or anything near those pimple but today i have dark marks on my face of the shape of how i applied my gel, and now i am feeling like the dark marks from previous breakout that i am dealing with from 3 months must be from the application of clindamycin and nicotinamide gel. I am feeling really pissed right now, because marks are big. Right now am applying that gel on my wrist and i will apply it for 1 week to confirm that this gel that i applied for even treatment of my post inflammatory hyperpigmentation was infact making it more dark and was doing more harm than good.
