Eyelash Hypotrichosis
"My 3ml bottle was more potent, and I think the 5ml bottle is more diluted to increase fluid ounces but does not work as well, due to the lower content of the active / main ingredient . Cost more, and not really more, just watered down in my opinions. I have both bottles and having them tested for strength . Poor result so far with the 5ml bottle, nothing like before."
