Yes, it definitely works and seemingly, on everyone. Everyone notices an increase in length and sometimes, an increase in thickness.

But here are some points to make about it:

• You need to use it for at least 8-10 weeks to get full growth and thickening of the lashes
• It's not cheap: $125 for a 4-week supply. I recommend using your own tiny eyeliner brush (rinse and air dry after using), which will make your supply last 6-8 weeks or longer
• It's not for everyone and it is a prescription medication, so you need to talk to a doctor or PA-C who can prescribe it
• You can try it on your eyebrows if they are sparse.
