I've used it about five times so far. The good thing about it is that it doesn't sting my eyes. I haven't noticed any effect yet, but I hope to see it as I continue to use it. Also, it's not cheap, so I'll continue using it, hoping for some decent results.
I assumed it would have a brush like a mascara, but it was more like a liquid eyeshadow brush. So, rather than combing the lashes, it felt more like dabbing. It doesn't sting my eyes, but how effective is it? I'm looking forward to continuing to use it.
I won this as a gift some time ago, and when I tried it, I found it to be so good that I've repurchased it. It doesn't obviously make my hair longer, but it does make it stronger and less likely to fall out, and it feels like it's gradually stretching, so I like using it.
My eyelashes have visibly become healthier. I've been using it for two weeks now and applying it twice a day, morning and night. It's easy to use and apply.
The brush is difficult to use. I think it depends on the person, as there are many reviews saying that the brush is easy to use, but for me it was difficult to use. Even after applying, I don't feel like the liquid is getting on my eyelashes. (My eyelashes are not wet) There seems to be a lot of serum on the tip of the brush, so when I apply it on the tip, it gets on my eyelashes, but it's too much. In terms of ease of use of the brush, I prefer Majo Majo.. Good pointsI feel like my eyelashes have grown a little since I started using it, and I think my lower lashes have grown more.
