Fact: This item really does work. My top lashes were short and pathetically sparse due to constant eyelash curling and my lower lashes were nonexistent. Both have grown dramatically in length and thickness after using this product. The change is very noticeable to myself and to others quickly resembling the infamous "insect legs" look. Through touch, my lashes feel awfully thick and tough (coarse) whereas before they felt very fine and soft. I can understand why mascara is no longer necessary for some women, though with the extra application my lashes truly look a mile long!
Now for the bad:
1. One ingredient in this product is the same ingredient in drops that are used to treat glaucoma. This ingredient apparently causes eyelashes to curl, and the irises and eyelids along lash line to darken. All of these side effects has happened to me. For example, I can really tell the eyelids darkening after a workout. I basically look like I am wearing a gray shade of eyeliner. My medium brown eyes has turned dark brown...purportedly irreversible. It is probably best to use the newer, "safer" version of this product. However, I heard that results were much slower.
2. Through initial use, the product burned my eyes and caused irritation and some dryness. The burning only lasted 5-10 seconds after each initial application while dryness and irritation vary in duration. This all went away after a couple months of consistent nightly use.
3. Results may be slow. It took about 2-3 months for me to really notice results. I have been using the product pretty religiously for the past 8 months.
4. Lashes will hit "plateaus" - periods where they will refuse to lengthen. Whether or not they will continue to grow is varied. I believe that there is a "set lash length" for everyone likened to a "set weight." Sadly, I feel that I have reached my limit. My "new" lashes aren't as long as I had hoped but I am Asian so who am I kidding? I'm happy just knowing that I now have more than 20 lashes per eye!
5. Hair growth is...UNCONTROLLABLE. Your lashes may be curling here but not there, growing longer here while other areas are sparse or not as long. The outer corners are especially long and curly for me. Overall lashes on my right eye is also a tad bit longer than that of my left.
6. Eyelashes like the hair on your head goes through cycles. Results from revitalash thus aren't permanent. Once the hair falls out, you start off once again with short nubs for lashes. Revitalash requires upkeep and commitment, which is expensive over time.
I have listed a lot of "negatives" in this review but I don't consider any of them horrible per se. Annoying? A bit. Still, I feel confident about this product and have recommended it to friends and family. It is a bit pricey and I am as thrifty as the next person in this economy, but one tube takes forever to finish. I have been using the same tube for 8 months and still have plenty left. Remember that a little goes a long way.
Update: Item has expiration date though I am not completely sure if this is printed on the box or tube. A fresh tube does wonder but I have noticed that an old tube does absolutely nothing! Maybe some users haven't seen results because of this? A reminder that it is so important that you purchase the product from a reputable source.
