Under eyes bunch up when smiling - how can I fix this? (Photo)

A little botox in this area can help reduce the bunching of the skin when you smile. You don't have to have crow's feet to have botox here.

Smiling is done by the contraction of the zygomaticus muscle which lifts the corners of the mouth and the cheek.
That process will create skin redundancy in the lower eyelids on many people.
This tends to get worse with age as the skin elasticity is reduced.
History of sun, exposure or sun damaged the skin allow skin deterioration to happen faster.
Does protect your skin from damage by avoiding excessive sun, exposure, and wearing sunscreen are likely to have these issues developed later in life.
There is no great treatment for this.
You can think of it as a normal function of smiling in middle-aged people.
