Better than cheaper lash serums and worked on my over-plucked eyebrows also (which other similar products have failed to do). I have quite good lashes however I definitely noticed the difference with this.If you have short eyelashes I would definitely give it a go.
Tips: Like a lot of these serums it is pricey but lasts for ages. I would recommend investing if you are paying for eyelash extensions which will cost you more over time and require too much maintenance. This product works and lashes look much more realistic when they are your own!!!
