Does bifid nasal tip get worse with age?

Bifidity of the tip cartilages does not necessarily change with age. There are some tip changes that can occur - usually a degree of drooping so there may be some related change. The tip drops as some of the support mechanisms that hold it up weaken with age and gravity also takes its toll!. There can also be some thinning of skin which may make the underlying tip cartilages look more visible.
So you may seem some difference to the tip but it wont specifically be more bifidity but the thinning of skin may perhaps make it look a little more prominent.
