Yes they can be ugly dark streaks of red and purple. Do apply a vitamin E based cream or lotion twice a day and continue doing so even post delivery for six months. They do fade but some hint of whitish silvery marks can always remain.

u can try using bio oil , u can mix it with olive oil as it's a bit expensive. it will help to keep you from itching keeping your skin moisturised.

apply bio-oil

red marks.will turn into light skin coloured marks..start putting coconut oil on them... later u can try rubbing basil leaves on them

it'll really take much days to heal. it won't disappear completely, but it'll fade.. try bio oil
