PLEASE PLEASE.

i was reading an article about rosacea, it says that only people age between 30-60 has a chance to get this kind of skin disease.
Im a 19 year old boy, asian w/ a fair skin before. I was dealing with acne scars, my skin were fair no sign of redness then after i slightly scrub the acne scars both on my 2 cheeks with a nailboard, the scars were minimize but the problem was after the peelnig of the brown skin, i noticed that the redness was still there and was gone for a few days, i was really stressed about those little scars left, so i used exfoliant (liquid) extraderm so it can remove those not so deep scars on my face, i used it 3 times a day after washing my face, and i was happy that the scars were gone but i noticed the part of my face were i scrub the nailboard were red.
My question is, Is this a Rosacea or a Blemish or the color tone of the abradded skin? If i get tan on the sun, will it vanish? my face were very white, my color of my face was quite different on my body.
