Latisse (bimatoprost) sunken eyes side effect?

Hi! So I was planning to try Latisse and was approved for a prescription, but a coworker told me something today that was concerning. She said her sister lost a significant amount of fat around her eyes after using it, to the point that her eyes now look sunken and her overall appearance has changed dramatically. At first, her sister didn’t think much of it because she had hooded eyes, and the Latisse actually seemed to improve that but over time, it apparently led to really affecting the fat around her eyes in a way that she didn't anticipate and didn't even realoze was happening right away. According to my coworker, her sister’s doctor said the effects are permanent and won’t reverse. Up until now, I had only come across more common side effects in the literature, like darkening of the eyelids, irritation, or unintended hair growth around the eye area...... Has anyone had this issue? Is this a thing?
