I just bought three more tubes of this after trying the one my sister passed to me. My lashes are pretty long for an Asian girl, so I didn't think much of using this product at first. I later realized that my lower lashes were really short though. So, I tried the Ardell Brow & Lash Growth Accelerator on my upper and lower lashes, and the parts of my eyebrow that were more sparse.
This worked amazingly! My lower lashes are now twice their original length and even starting to curl outwards! The sparse areas of my brow (particularly the ends and a part I was trying to grow out to get straight brows) were already getting denser.
I recommend buying online from Madame Madeline for the best price ($3.25 each or 3 for $8.25, shipping $3.50 to Canada). Such a wonderful product at a great price~
One con is that the brush doesn't reach all the way to the bottom of the tube so you can't get it all out completely. Another is that sometimes the product gathers at the end of the brush and smears on your face if you're not careful.
