I have used this every night for 3 weeks and really can see that my top eye lashes have grown longer.
The lower lashes have not grown much but not sure if you can use the serum under your eyes as well?
It is easy to apply to top eye liner line - much easier to apply than those that have a mascara wand to apply the serums. They have clumped in a lump so hence I like this smooth liner applicator.
