I've read where it sometimes took 25-50 flushes for people to get results...
Comedones and bad texture like bumps are usually clogged pores or something on the outside... not much you can do on the inside for that.. they can be helped most with salicylic acid. I buy it in bulk (google where to buy salicylic acid) and mix it with liquid soap at about 10% bit you only really need 2%. It only dissolves in alcohol or liquid soaps though.. but it's amazing.
Brown Sugar and coconut oil scrubs work well too.. the brown Sugar mixed with the fats will produce an alpha hydroxy acid like effect. You can use Sea Salt and raw honey too for a good scrub... but be gentle!
