After Latisse, my eyes look really sunk in and horrible. My eyelashes aren't even full anymore, they all have spaces (Photo)

The combination of minoxidil and Latisse has not been studied. I don't advise use of minoxidil on the eyelids. 

Thank you for your question in regards to Latisse.Yes, you have to continue using Latisse for lash growth. It is a maintenance application. When you stop using it, your lashes will go back to original length prior to Latisse. To be sure what is best for you, see two or more board-certified...

You want to make sure that you've removed all of your eye makeup before latisse to your dry/damp lashes. Obviously, the latisse will make them wet. Make sure to clean up any excess product with a q-tip. Best, Dr. Nazarian

It is never a good idea to use an expired product. Especially around the eyes which are particularly sensitive to irritation. If you haven't had a reaction, great. But I would certainly recommend that you buy a new jar pronto. Best, Dr. Nazarian

Latisse is meant to be applied around the eyelashes and should not be associated with the side effect that you are describing.  Please consult with your physician before starting Latisse to see if there is any contraindication for you.

Since latisse has not yet been tested on breast feeding women, I wouldn't risk it. Wait until you've stopped breast feeding your child before resuming use. It's always better to err on the side of caution. Best, Dr. Nazarian
