Yup! All my scars are the same color as my regular skin now! I didn't have much to begin with, the redness was like yours. It even made a hypo-pigmented scar return back to regular skin color as well.
When you do get your dermaroller treatment done (I just do it myself now because my esthitcian gave me the dermaroller for at home use) use something afterwards like vitamin c, I've been rotating between that and copper peptides. Applying a good product afterwards really speeds up the fading of the red marks. Try to ensure that the product you use doesn't have too many artificial ingredients, the more natural the better because the micro channels created into the dermis during dermarolling causes everything you apply onto your skin to go in really , really deep pretty much into the dermis. This is extremely benefical if you use the right products.
