I have always looked young for my age... Until I used Latisse, which caused hollow, sunken eyes!!

I also experienced periorbital fat loss from Latisse. I used it for 3 years. It's been exactly 12 weeks now since I last used it. My eyes are recovering, but they still aren't completely back to normal. It remains to be seen whether or not they will completely recover. Even with shorter and thinner lashes, my eyes now look way better than they did while was using Latisse. They look years younger already.
I think your chances of at least a partial recovery are very good.

Correction - it's been more like a year (give or take a month or two)

I was on Xalatan (latanoprost) to treat open angle glaucoma and i got not only sunken eye look, but overall fat atrophy all over my gace it aged me like 10 years, i had no idea this could happen, every one was telling me i looked sick, if i was having trouble sleeping and stuff like that, at the same time i was using minoxidil, which is supposed to be another cause for sunken eyes, but i realize that the dark circles appearence began before that, so i read something called "prostaglandins associated periorbitopathy", so long story short, i stopped the drops like 3 months ago and i´m almost recovered completely and i continue on minoxidil, still getting better, so it was clearly the Latanoprost.
Good news, it is completely reversible after stopping the use of it.
i was on xalatan for over 2 years

I appreciate the photos you posted. I have not yet used Latisse (although I have purchased it and it is sitting on my dresser) but I have been using over-the-counter eyelash growth products for years. I have a similar "sunken eye" look which I did not associate with these products. About two months ago, I began to use the Elizabeth Arden Prevage eyelash growth product and I noticed the sunken eye look. Allergen, the company that makes Prevage, also makes Latisse. I am wondering if all these products cause problems.

I too used Latisse and had periobital fat loss. It happened over a period of about a year. I was always focussed on the eyelashes. Then I was looking in the mirror one day and noticed my eyes looked sunken. I knew something was wrong but I just could not figure out why. I just happened to read about latisse on realself and knew right away I was losing fat around my eyes. My sulcus was deep and was especially noticeable when tilting my head up to apply mascara. Even though my lashes were longer, I looked much older than I did in pics taken before using latisse. I stopped using the latisse about 4 weeks ago and the good news is the fat is returning because my eyes have started to move forward and look much younger again. Plus my eye lids are not red and the whites of my eyes are clear again. I was constantly having to use eye drops. My daughter-in-law has long lush lashes and when she saw what had happened to me she said she would never use it if her lashes thinned as she gets older. We are both ordering a fabulous mascara called Younique. I've read reviews on it and seen before and after pics and it works great to achieve thick long lashes. Also, I have blue eyes and I would not want to have a change in colour. I think it would be strange to look in the mirror and see different
coloured eyes. I found a medical abstract where elderly people who were using glaucoma drops and stopped the drops, regained the fat that they lost around their eyes. There were before and after pics that clearly showed the fat returning and the sunken eye look gone. In the abstract, the doctor stated that all the patients regained the fat back over time. It looks like most of my fat has returned and like the glaucoma patients, I am pretty sure It will completely return. At this point in time my eyes look pretty much like they did before latisse and its only been about a month. So I don't think you should worry. If you give it a few weeks, I am sure you will gain the fat back around your eyes. Another bonus is I'm saving money!!
