"this spot gel is amazing! it started working for me within 3 days. i had no side effects with this spot gel, i have oily skin and very big pores and that means i am spot prone. i went through a phase of acne and went to the doctor and got prescribed duac and i&#039;m so glad that i was! it made my skin clear as day! i wouldn&#039;t recommend using it after it is two months old, as it doesn&#039;t seem to work as effectively after that amount of time but you can always get a new tube as it is usually used up in that time!"
