I scar easily as well, being darker in skin tone.

I've had success with the New Skin, though I found it rather on the expensive side. The last time I crashed and had a fairly deep abrasion from my t-shirt rubbing my skin off from my chest. I really didn't want a scar there as it's visible when I wear open neck shirts. So, I babied it like nothing else.

I first daubbed the area with tea tree oil to prevent infection, then I q-tipped some unrefined shea butter (and I was pretty generous with the amount). Then on top of that I put a couple of drops of neem oil. I covered the area up with a gauze and changed it twice a day. Did this for about 3 weeks total until the skin wasn't open anywhere and now you can barely tell anything was there.
