please tell me some home remedies for acne & acne scars ?

After I get a pimple I usually have red left over from it and it last for weeks. I was wondering if there are any products or home redies I can try that is supposed to help with that.

I have severe acne scars and would like to know what is the best acne scar treatment to remove scars?
I heard about acne blue light therapy. Does it really work? I was advised to remove my scars using Laser resurfacing but it is too expensive for me.

I have several pink acne scars on my shoulders and chest. I’m afraid I’m going to have to live with bumps and pits in my back for the rest of my life. Is there any type of plastic surgery to remove them, like placing the skin or something? I’m sorry, this is just ruining my life.

I have a lot of acne scars on my back. Please help. I need some simple home remedies.

will somebody tell me, is there any facial cream or lotion to remove, erase, diminish or minimize pimple/acne scars?

Pls reccomend only nice cream or medicine- those which are tried by yourslef.

And where do you buy it? Thank you very much for ur answer…

Thanks

I am African American and have medium brown skin. Basically the same color as Rihanna, but without the clear skin. I have a lot of dark marks on my face and neck from acne and a few from ingrown hairs. I rarely have any breakouts anymore, but the scars are still there. Are there any good over the counter products that would work for me?
