100 plastic surgery

Judging by the before and after photos, it is obvious that Seacrest has changed dramatically through the years. It wouldn't be an exaggeration to say that he underwent some pretty intense plastic surgery to look like that.

Ryan Seacrest's forehead is smooth, but still has a few lines - the same happens to his crow's feet around his eyes - making his botox results seem more natural. He made a smart choice to not overdone his face to the point that it stops having any facial expression.

It is apparent that Seacrest had a quick fix to his teeth by getting veneers, a really expensive teeth treatment that the majority of celebrities prefer.

It is evident that Seacrest's nose used to be very bulbous in the past, but now the shape of his nose is changed as the roundness of his nasal tip is reduced, an obvious indication of a nose job.
Seacrest's eyes are more walnut shaped, a sign of an upper eye lift.
When asked about how he keeps himself looking young, Ryan Seacrest has never revealed his secret. For instance, when someone asked how he looks younger than his age Ryan Seacrest comically replied: "placenta." In addition, Ryan Seacrest has been quoted stating the following about botox: "I've never done Botox in my life. But I've probably tried everything else under the sun."

Conclusion: Whatever plastic surgery procedure Ryan Seacrest undergoes, it is obvious that works for him as he appears younger than his actual age.
 In these pictures of Ryan Seacrest it appears that he has enhanced his appearance with some plastic surgery procedure.
In this picture his nasal tip looks less round and more defined than before, although his facial expression is not the same than in the previous ones, on which there is not a remarkable difference. If he did a nose job (rhinoplasty), it looks very natural and not over done as other celebrities.  Usually when the nose takes the attention from the face is in a negative way, taking it from other attractive features as the eyes, mouth or cheeks.  Some doctors say that the wide of the nose shouldn't be bigger than the eye's.
