I first heard of Mavala Double Lash on the boards of makeupalley.com back in 2005 or so. This was before the advent of Latisse, or Jan Marini's lash growth product, and really the only main competitor was Talika Lipocils.
Since Talika was much more expensive, I decided to try Double Lash instead. Unfortunately, it wasn't readily available in the US, so I had to get it through other means. The first time I got it was through my friend Aurelie, who purchased it in Canada. The second time, I had a kind-hearted Singaporean makeupalley-er purchase it for me. The third time, I got a brand new one in a swap with a Greek makeupalley-er. Through the years, it has been more easily purchasable in the US, via websites such as whatshebuys.com, but I must note that now it is always in stock at Douglas cosmetics for the pocket-friendly price of $16.50USD.
The product comes in a small glass bottle, about the size of a nail polish, and not very fancy. There are 0.3 ounces of product, but you will probably not be able to use it all up... And besides, like all liquid eye products, you should replace every 3 months.
The applicator is a spooley brush that resembles a mascara brush. As for the actual product, it is a whitish liquid, quite watery in texture. There is no scent or odor. It is to be applied mainly on the lashline, so as to encourage lash growth. I personally only applied it at night, but some ladies have used it underneath their mascara during the daytime. It does dry clear, but while the product is on your lashes, they feel a little crunchy. I always wash off any residual in the morning with some warm water so I can start with fresh, clean lashes.
So does it give lush lashes? Well, that is debatable. To me, this is more of a lash conditioner. It restores the lashes after too much mascara use or tugging when removing eye makeup. With Double Lash, I did find that my lashes felt much softer, and I had less lash loss. Each individual lash also felt and looked plumper. I found that my mascara wore better, meaning that my lashes looked more well groomed and glossy with mascara.
But, don't expect crazy lashes to start sprouting, or lashes so long you'll have to trim them down. Save that for Latisse or something that is medically proven. With Mavala, you will just have "good lash days" with your soft, glossy, conditioned lashes. For me, that is enough (for now!). I don't want to put the mascara business into ruins - haha.
Also, I just want to note that I have sensitive eyes, and did not experience any irritation whatsoever. This is a continuous repurchase for me. Love it!
