Hey there!
I'd like to recommend Murad because I've heard some pretty good experiences from people who used it and also I, who have been struggling with forehead acne since middle school, found that it works pretty darn well!
Murad claims that in just 3 days, you'll feel a difference and in 3 weeks, you'll get results. That's probably just the average. For me, I felt the difference after the first try and then in just a week, I felt all my forehead pimples come to a halt.
I was just using 2 products from Murad:
Clarifying Cleanser
Clarifying Toner
For Moisturizer:
Say Yes To The Tomato
I figured that I wasn't using the right products after I saw AND felt the difference from using these two products. Before, I was using clean & clear and neutrogena (bleh) and I was breaking out everywhere like forehead, nose, cheek, chin. Discovering Murad was like finding the "holy grail" for me. I can now confidently pin up my bangs and show off my forehead lol.
Aside from a cleansing routine, exfoliation is also important. I discovered Buf Puf and after I ran out of my Murad cleanser, I switched to Cetaphil for a gentler cleanser, and boy did this combo do wonders!
