Hi my name is Sadiya..and m 25 years old.
My acne started when i was 13. At that time we all thought that its normal and i will finish after my teenage..but when it never stopped...it started getting worse and when i was 18 i had a bid pimple on my cheek and then it left scar. Now m 25 and m facing sever acne problem..i have used many treatment option like:

>Proactive
>Lazer treatment

but both of them did not work..in lazer it seemed ok in the start but now its almost same as it was before..i think i stopped using those lotions which they recommended...may be not sure...i have used them afterward when my treatment was over then i stopped ...
My acne are BIG, filled with BLOOD and PUS, leaves SCARS and are very painfull that i can sleep at night because i cant put my head on the pillow cause of acne on my cheeks..so i have to lay straight...

Is there are treatment..?
