Review (4/5): It works, but still takes time.
After damaging my eyelashes with a subpar eyelash curler, I noticed that an entire section of my eyelashes on one eye were severed. I heard that it could take 6-8 weeks for lashes to start growing back. I bought this serum, and within a week I could see small lashes coming through. My other healthy lashes also got thicker and more pronounced. No more eyelash curlers. And now I will use this product regularly.
