Skin problem sometimes caused by not getting enough sleep, poor eating habit, hormones, age and many more. So, if you want your skin to be acne free, then you should take care of your health. And if all else fail, then it's time for you to put some acne medication. That is what I did when I had acne after my transplant. I am glad the medication my doctor prescribed me was very effective. In just few weeks, they are gone and my skin never had acne again. I didn't even finish the bottle of the acne medication and it is still in my medicine cabinet. Yes, that powerful :-)!
