Bad skin acne scarring. Can someone recommend what will work? (Photo)

Hi, I have been to 4 clinics in London, Harley Street and elsewhere and have received conflicting advice often slating the other treatments. I didn't really feel comfortable with any of them as I felt they just wanted to sell their products. None of these were doctors or dermatologists but they called themselves skin specialists. The conflicting advice has left me super confused and I just want a fix for my skin. Can someone recommend what will work :(
