What will fade red acne marks?

[Apricotton]

I’ve got some red acne marks I want to fade. The active spots have gone, but the red marks remain. I already use vitamin C. Has anyone found anything ti be particularly good for fading them? Thanks.

Retinol

You can get micro abrasion which will work much quicker

Time.

If you need to speed it up then salicylic acid and retinol, both of which will help stop your having spots develop in the first place.

Niacinamide.

Thank you very much everyone for your responses. I’ve got my acne (fingers crossed) under control, so I’m just in the nice position of sorting out the red marks. I’m very pale, so the redness really stands out. I will look at all the suggestions. I want to throw everything at it, so I need to figure out what products I can use as part of the same routine. I’m hoping I can also shift a red acne mark I’ve had for 17 years. Microdermabrasion sounds good as it may also help with a pitted scar I have, although I’ll probably have to save up for that!
Thanks again everyone.
