This isn't news to anyone, but I feel it bears repeating: Acne scars are rubbish. Anyone who has suffered from post-pimple hyperpigmentation knows this truth to be self-evident. And, post-puberty, they affect every age and skin colour. They manifest as red or brown marks that can last weeks — and sometimes, for the really unlucky, months. As someone from that unlucky category, I can confidently tell you that I have tried every — and I mean every — remedy known to man.
That said, quite a few at-home, non-prescription products do a damn good job of fading those marks faster, to get you back to the even-toned complexion you had before that massive breakout. And, for the most part, they don't cost an arm and a leg. As anyone who has spent hundreds, if not thousands, of pounds over the years in a fruitless effort to win the war on spots knows, that's a huge selling point. While these products, for the most part, have no real effect on actually preventing blemishes, we know that fading those dark marks is half the battle.
