Brand new bought in January Good for 24 mo unopened 12mo once opened This stuff works! I used to pluck my eyebrows down to less than 1/2" so I could draw on the tail during my super goth phase. I had them like that for 7 years. After trying for over a year letting them grow back in I almost gave up. I never thought they would ever grow back and considered getting expensive micro-blading done. It's been 2 months now of almost nightly application and I have eyebrows again! I have terrible hair genes so if it worked for me it will work for you! bonus! you can also use it on your eyelashes! mine are thicker and longer now too! I always had to wear mascara before to even see them, now I don't!
