Advice on diminishing appearance of white but raised scars

Hi. I have quite a few scars from when I was an depressed teenager all over my left arm. I am now a perfectly (well, almost!) mentally and physically healthy woman who is unable to wear short sleeves due to what I did over 7 years ago.

Does anyone have any advice on how to lessen the appearance of these scars? They are small-most no longer than one inch- but the fact that they are raised makes them noticeable. The scars are white, so I know I will likely not be able to regain the pigment, but has anyone undergone any effective treatments to making already white scars flatter?

I've read about silicone sheets but I'm unsure as to whether they only flatten red, hypertropic scars.

Thanks in advance for any advice.

P.S. Please no comments about "wearing scars with pride" or whatever. I want them gone. And to anyone who is still doing s-i: you need to realize that when you do get better, which will probably happen, a constant reminder of how you used to be is NOT a good thing, especially when you are trying to thrive in a professional environment.
