hi.. u can try using concentrated vitamin E oil to lighten up scars.. it worked perfectly for me in the past as i have plenty of ugly looking scars on my legs too.. can give it a try..

for your skin, maybe should try to use sunscreen blockers when u r out in the sun and other whitening creams too..

short hair looks are nice dear, just get a good hairstylist to give u some good ideas and whoosh... *perfecto*
and maybe u can try highlighting it too.. it gives a fresh and vibrant look..

dun worry dear, its the confidence that u should have to look pretty.. when u are happy, u r pretty!!
