I thought I was crazy for a while within the first 2 months, wondering why my eyelashes looked about 2x longer, and definitely in higher density than before. A lot can happen in a short(-ish) period of time. Now at 4 months, my body hair has now become thin at the roots (in some cases, it seems that near-terminal hairs regressed to the vellous stage), hopefully with some epilation, it will become unnoticeable in time. Also, I have to confirm the eyelash growth; I compared pictures. To be totally sure of the changes going on, I made a goal to take a self-pic every day, and in reviewing the pics in sequence, the changes are subtle, but then they start to to pile up. Keep in mind, the changes may sneak up on you.
