Adapalene / benzoyl peroxide
"I used tactupump while at home for a week and it killed my skin, it felt raw, was red and VERY DRY and literally felt like a bad sun burn, then I went up to my cottage and my cousin had the same perscription, so I just tried to use it again and IT WORKED WONDERS! For the week that I was there... Weird? when I got back home I continued the same skin care regiment I was using at the cottage AND AGAIN I HAD THE WORST REACTION! Like what? So I went to my dermatologist and she said to look into the type of water at my house compared to the cottage, so turns out we have a SOFT WATER filter at the cottage, and really hard water where I live at home, she recommended me invest in a soft water pump but they're around $900 :("
