I have been using fLash serum for about a year now and I love it. I have tried others previously but didn't get the results that I get with fLash.
Within about 3 weeks of when I first started using it I noticed the eyelashes looking longer. But as with all hair, the long ones would fall out and the new ones would come through.....so even though they are long for a period, it does then go through a phase of being a bit shorter again, but never fear, they too will grow.
I have noticed that my lashes benefit most having a break, so after every 2 tubes I go through, I give it a rest for a couple of weeks before starting a new one. Unfortunately I find the tubes don't last that long so you do need to keep restocking. Pity they don't make it in a bigger tube with more product in it.
In order to appreciate my review you need to know something about me - I suffer from trich. As a result my lash follicles are just exhausted of having to grow out again and again. So growth is very, very, very slow and extremely sparse and the length my natural lashes will now grow to is much stubbier than the length they would naturally reach. I've tried a couple other lash growth products and moisturizers but they won't help my lashes grow because they work by conditioning the hair, only a lash serum that actually stimulates the hair follicles to grow will work and this works. This is a lash serum - it works to stimulate the hair follicle for lash growth. If you are just after something to keep your lashes healthy and soft you can just use a dab of your facial oil on your lashes but if you want actual growth beyond the length your lashes your lashes will natural reach this is the product to go for. Because when I use this my lashes grow at a more normal rate and grow back to their original length if allowed to. While some might not consider that outstanding it is a huge improvement considering they would barely grow back at all. I have repurchased this multiple times and it's an absolute necessity for me to have at all times. I think if your lashes haven't been subjected to as much trauma you can get pretty dramatic results using this. I haven't had any irritation using this and it's more affordable compared to some other competing brands costing 2, 3 times as much or more. I'd definitely give this a shot before splurging on some of those overpriced lash conditioners.
Tips: You can apply this in the morning but you have to wait about three minutes after applying this to your lash line before applying your makeup or other cosmetics to your eyes to allow it to absorb. Because of this I prefer to use this at night before bed usually as the last step in my routine.
