I need help to remove this white scar i have due to applying chapstick on the skin...?

here is my problem, about 2 months ago, the corner of my lips started to get chapped so i applied Carmex chapstick on both sides of my mouth, the next morning i noticed two big white scras on each side of my mouth. I tried applying vaseline to make the scar return to my normal skin color (i'm black my the way) but to me i think it made it whiter and had no effect, i started using BIO OIL on the white scars to make it go away its been 3 weeks now and i havent seen a change at all i even tried puttin make up to cover it but the foundation hasnt helped at all im startin college next month & i dont want this to interfere with my life any more please help me , please help me get rid of this thank you!
