I just want to ask if Aspirin Mask can help to remove acne scars?

Feel free to try aspirin (mixed with something soothing like yogurt) as a scrub, because it's as cheap as it gets, and it's an acid (salicylic acid), and stronger acids are used as exfoliants.
But please read this first, to see what kind of scars you have, and what to expect as your skin goes through changes:
