A ShapeShifter?

So there is this Herbal Essences commercial mystifies me. The person pictured below dances around for thirty seconds and supposedly sells the shampoo product. But what drives me insane is how different this woman looks in each segment of the commercial. Someone want to venture a guess as to her age?

Here she is looking like she's 24. One caveat, she is jumping, and is in mid-descent.

And here at Age 25; slightly sharper cheekbone structure and less baby fat.

Age 27?

And at Age 28, maybe?

Perhaps 30+?

My only other theory is that there is more than one model on the commercial; but the editing seems to be seamless. That the model sometimes wears yellow and at other times pink is not enough evidence of more than one model.

Quite a mystery.
