Red acne scars (PIE) removal? (Photo)

I have tried sooooo many different treatments and products but nothing seems to work! I get hot flushes all the time and my red scars appear more visible when that happens. I still look like I have acne! How can I treat this? Is Excel V effective for this? I’ve bought so many different skin care, from retinols to alpha arbutin, you name it! I’ve done facials, laser facials, why is nothing helping? I regularly wear SPF too.
