I don't have something like a favourite - I'm searching always for something better.
There are only two mascaras I keep backing up - because I like what they do with my lashes. I have naturally curled lashes, so I just need volume and lenght - but I hate it when everything gets thick and layered. The two I found until today I can live with are the Multi Action Mascara by Essence - I guess everybody knows it, there are enough reviews and everybody has it's own opinion, and the Hypnotic Volume Mascara by Look by Bipa. Second one is for me kind of a cheaper version of the CoverGirl Lashblast - I owned and loved, but I don't want to order anymore and I'm not willed to pay that much for a mascara that actually doesn't cost that much in the US, but for me. The difference is the brush - but for me it's ok, because I don't like rubber brushes.
