I have both of these but im wondering which is better as an exfoliant cream .

Or does 1 do something the other doesnt , exfol has 2% salicylic acid . Latic power 10% L Acid .

sorry if its a noob question just interested .

and which would be better for scar treatment . thx

The Lactic is better for superficial scars. The Salicylic penetrates deeper in the skin and is better for deep or buried scar tissue.
