Its the second one I'm using. Other similar products from other brands have caused some irritation and darkened my lids, but this has not caused issues (though i still try to to use small amount and every other night to make sure the irritation stays at bay). Within my routine, quite a strong result appears on 4-5th week. I use the same product on both my brows and lashes. Although I have great thick dark brows, it helps to stimulate new hair growth in couple of areas (ends) where they lack growth. My lashes are also not bad, but using Revitalash makes them longer and silkier. At some point my lashes grew a few mm longer, really strong result.

I find it so hard to see if this has amazing effect on my lashes, but the girl who does my eye lashes says they look long and healthy even though I wear eyelash extensions all the time. It does sting a bit if it gets in your eyes (only happened to me when I was putting a lot of eye drops) and you need to use it eeeevery day. I've bought it twice already, it lasts very long!

Brilliant product, started to notice a difference in length after one month

Love this lash serum, made my lashes very long, no necessity for lash extensions, really works!

Works after a while but makes my eyes very red and irritated.
