How I got long, fluttery lashes within a week by just adding a simple step to my night-time routine....
I purchased my Revitalash serum from eBay as that was the cheapest place I could find it for the most millilitres. It still cost me a good sixty or so pounds but I got 3.5ml which costs around £100 elsewhere, so a pretty good saving eh? I was wary about it being the real stuff or not but I don't think for that kind of money they would get away with selling fakes. Plus, (spoiler alert) it worked wonders on me so it must be the real deal!
All you have to do is apply a thin layer of along your upper lash line before you go to bed, easy peasy. It also transfers to the bottom lashes when you blink so you don't need to apply any more than one layer to the top lashes, winner. It conditions the lashes and helps the growth of both the top and bottom lashes. It dries down pretty quickly so you could apply it on a morning too but I prefer to just add it in to my night-time routine.
I did get a little bit of itchiness at first along my upper lash line but nothing too major and I soon got used to it, I don't get any irritation at all now. I do have sensitive eyes and wear contact lenses so whether it's down to that I don't know, but to be honest, the irritation was so minimal that I would put up with it all the time if it means I get to have lashes like these.
I can't even begin to tell you how much this lash serum has changed my life, like I actually have lashes now it's insane. They're fuller, longer and they just overall look amazing! There's no more jealousy or feeling the need to wear false lashes, or fork out on lash treatments (apart from this serum ofc) like it's just craaaaaaazy. I never thought in a million years it would work so well (or at all) on me, I thought my lashes were a lost cause. I never planned to even post a review of the serum on my blog which is why I never took any before and after pictures but I SO wish that I had because the results are incredible. I'm going to put a couple of iPhone quality selfies below so you can see how my lashes before were practically non-existent and how long they are now. Granted they're not the best quality and I wish I had better quality close-ups to show you, but these will have to do.

If you want to try it for yourself, I got mine here.
