In June 2011, I had lash extensions glued onto my own lashes while on holiday. The glue was so strong, the false lashes were still stuck fast after 4 weeks and I was getting a little tired of resembling Barbara Cartland. The lashes were eventually removed by a patient beautician using glue softener and some sort of scraper. I think the false lashes weakened my own lashes and I lost a fair few lashes when the falsies were scraped off. Oh Dear! My eyes are my best feature (I am not bragging, the rest of my face is below par) so I was rather concerned that my own lashes looked short and sparse particularly at the inner corners. I am a mascara fiend as well and I noticed that my usual mascara seemed to clump on the wasteland of lashes. It was then I decided that my lashes needed some TLC. I decided not to use mascara for 4 weeks and I bought Mavala Double Lash Night treatment. To be honest, I could hardly tell any difference at the end of 4 weeks so picked up my neglected mascara. THEN I noticed a difference! The mascara (the same I always use) adhered to my lashes like never before. I only needed one coat to see the difference. My lashes were definitely longer in places so I could see a slightly spikey effect. The corner lashes had grown back so the mascara was landing on lashes instead of eyelids. Each lash seems to be thicker rather than me having more lashes. Mascara does not clump and the lashes are more separated than they ever used to be (when wearing mascara).
I do not know if the serum swells each lash so that it looks thicker (which would account for the mascara not clumping) but whatever it is, I am happy to recommend (as I have done to my friends).
The serum is rather thin and feels like water when applying it. It dries very quickly and I put several coats on. The serum does seem to last a long time. I think it will last at least 6 months which is a good investment. Don't take my word for it. Just try it and see.
Update 4th September 2011: In the past week, three people have commented on my eye lashes saying my lashes look thicker and longer and have assumed I have changed mascara which I haven't. I did not seek their opinion. I may have been optimistic thinking the serum will last 6 months. Four months might be more accurate. I will be buying my second bottle before then.
