When the mongolian spots fade?
Mongolian spots are present at birth, and most of them fade (at least somewhat) by age two. Most have completely disappeared by age five. If Mongolian spots remain at puberty, they are likely to be permanent. Fewer than five percent of children with Mongolian spots still have any by adulthood. Those who do tend to be the ones with multiple, widespread spots, or with spots in unusual locations.In the unlikely event that it is still present after puberty, there MAY(by then) be safe, painless, effective ways to remove them — if she should so choose.
