"by far the most helpful medication for my acne scarring. i use it at night and use aczone during the day and they do wonders.  i have cystic acne, so to have tackled these kinds of scars needed some serious patience and care. i recommend this to anyone who struggles with this type of acne. i know how hard it is to get rid of those big red inflamed scars, and this definitely does the trick. you just need a lot of patience because it does take some time but you will see a difference within 1-2 weeks."
