If you want longer lashes, start by curling your lashes with an eyelash curler. I use ELF's (Eyes Lips Face), so I can't recommend you a Sephora one However, I can recommend some really good mascaras from this place!
I bought the Sephora Favorites Give Me Some Lash for $30, which includes 6 deluxe sample-size mascaras, all of which are best sellers at Sephora. They all actually did a phenomenal job of lengthening! Here is a mini-review of each one, as well as links ( the links are the first words, the name of the mascara lol! not the title tho!)
Buxom Buxom Lash Mascara is my all-time favorite mascara! It adds a ton of volume with its ginormous brush, but it also does a great job with lengthening. Five stars and two thumbs up, this mascara is the bomb
Note that it is a volumizing mascara, so if you have thin/sparse lashes it will work better than a mascara with a "wet" formula.
Bare Escentuals bareMinerals® Flawless Definition Mascara is a great mascara for getting and defining every lash. There is virtually no clumping and the thin, dense bristles and long wand help to add a ton of length.
TARTE LIGHTS, CAMERA, LASHES!
Tarte Lights, Camera, Lashes! is a great mascara that lengthens, curls, volumizes, and conditions. It contains waxes, which help not only to lengthen but to hold up thin lashes and keep them from drooping. It, just like the others, can create either natural long lashes or dramatice, flared, false-lash type effects.
SMASHBOX LASH DNA
This mascara is no longer sold full size by itself, only with the Give Me Some Lash set! It had a unique brush and worked great for creating dramatic lashes, but the formula may have been too "wet" for thin lashes, as it took a while to dry. Thin lashes may have been droopy with it. Thick lashes however would be just fine with this mascara.
MUFE AQUA SMOKY LASH
MAKE UP FOR EVER Aqua Smoky Lash was the only waterproof mascara in the set. It has a very dense brush that covers each lash completely. It is a volumizing formula with waxes also so yet again it will be fine for thin lashes. It adds quite a bit of length and is very waterproof.
CLINIQUE HIGH IMPACT MASCARA
Clinique High Impact Mascara is also a volumizing formula with waxes, so it's just fine for any lashes of course. It needs to be wiped off a little before using as the brush collects way too much formula, but once you do it works just fine and adds much length and volume as promised.
ALL of these mascaras are under $20 excluding the Make Up For Ever Aqua Smoky Lash which is $22. I highly recommend each and every one of them, and I recommend even more that you get the sampler set for $30 as you may find yourself using a different one every day and being just as happy, like I am I really hope this helped you out, if you have any questions feel free to PM me
