Définicils is rated 4.7 out of 5 by 1311.
Rated 5 out of 5 by from I will use Définicils forever… This is probable the best mascara I have ever used in my years of wearing makeup. I thought because I had a high cheek bone to make mascara smear on my upper cheeks, but because I was using those cheap ones all along. The Définicils DOESN’T STAIN on my upper cheeks; it really DEFINES my lashes; it STAYS ON all day long, and most importantly, it’s so EASY TO CLEAN IT OFF even while I’m applying it onto my lashes and it touches my skin, it comes off easily with just a tip of my pinky. It’s also easy to use with the lower lashes, too. Love it! My lashes never looked this good before. I will never go back to use those cheap brand mascaras again EVER!!! I will use Définicils forever…

Rated 5 out of 5 by from Great for everyday wear and does not clump! I use Defencils as my everyday mascara. It goes on smooth and does not clump. My eyes run often because I have suffer from sinus and allergy problems. With Defenicils I never have to worry about my mascara running or smearing because of my runny eyes, in which I wipe and dap quite often! I highly recommend using the lash primer if you want a more dramatic look. Like I said before I use this as my everyday mascara because I want a more natural look while at work. It is great at defining your lashes, giving them a fuller and longer appearance while still looking natural. When I go out at night and want a more dramatic look I use the lash primer to give a more dramatic look.

Rated 5 out of 5 by from the ultimate in mascara I have used this mascara for about 15 years in several different states and I can tell you that it is the best I have ever used . I like the basic definicils--the waterproof sometimes doesn't give me the fullness anddifficult to "build" lashes with several coats. And I loved the navy color when it was offered but the basic black works with everything. lazy about taking off makeup before going to sleep?--the definicils basic doesn't break off the lashes or cause them to thin so getting lazy isn't the disaster it used to be. A bit expensive for something that has a short life span but I like this one the best of all brands on the market.

Rated 5 out of 5 by from My Only Mascara I found Definicils years ago after college. It quickly became my favorite mascara. A couple of years ago, it wasn't available anymore...for quite some time. I tried others: other Lancome mascaras, other department store brands, cheap brands, organic brands...all were lacking. Most made my eyes burn later in the day. Then, one fine day, I saw Definicils again on the Lancome website- my heart soared! I immediately bought some & had it shipped the fastest way possible. No more burning eyes! The ease of application & the final look cannot be matched! It's very simple to remove, too. I'm a forever Definicils customer!

Rated 5 out of 5 by from BEST Mascara on Earth This is the best mascara hands down. I am on my 5th tube and will never stop using it! I have dry lashes and this mascara seems to condition and hydrate them. It never clumps or flakes. It lengthens, adds volume, and separates lashes. The brush is also the perfect size and the formula has a great consistency. I have sensitive eyes and this does not irritate them. Thank you Lancome for making such an excellent product.

Rated 5 out of 5 by from Everything is good ! I am a minimalist when it comes to make-up; not when it comes to lotions and potions though - as my husband says. So, all type of things go on before my make-up, and I notice when using most other brands they smear. I apply mascara before anything else, first, to get an idea of what and how much else I need. Just for reference point, my hair, skin and eyes are very light, my eyelashes and eyebrows without colour are not even noticeable. So, I really like the "lighter brown" that Lancome offers, it just looks better. I also have used their brow colour, in a mascara type wand, for years. It also comes in a light colour and if you are lazy like myself, it looks good and is easy and takes mere moments.

Rated 5 out of 5 by from Definicils - Absolutely the Best Mascara Ever Definicils is Absolutely the Best Mascara ever made!!!! Smooth & sooo easy to use it creates the sexiest, longest, lushest lashes imaginable. Best of all, it goes on so lightly that you forget that you're wearing it. It comes off easily,too. It doesn't run, flake or streak, either - even if you "forget" to take it off at night... I'm such a fan that I've recommended it to everyone I know & now all my family & friends are buying it too. You'll adore it too! We all do!

Rated 5 out of 5 by from Définicil This has been used for many years because it has stood the test of time. It is easy to apply without clumps or heaviness. It is a pretty and natural color for lashes. It separates and lengthens each lash. It lasts through tears yet is easily removed with gentle cleansing. It accents the eyes to be noticed for beauty without being too much. This one product has probably created more compliments for my eyes than any other. This product works well alone or in company with others. It stands alone in its performance. For my personal use it is the only product that I use. No eye shadows or eyeliners for me.

Do you no longer carry Immencils mascara? If not, what would be the closest equivalent?

Asked by: cairnrescue
i don't think they carry that type of mascara anymore, but to me the closest one would be the Lancome Hypnose Drama

Is this mascara dermatologist tested and non-comegenic?

Is the definicils mascara for sensitive eyes?
Asked by: Angel
I have sensitive eyes, particularly when it's allergy season, and I have been using this product for over 20 years! I have never had a problem with Definicils; it has never bothered my eyes nor has it caused any irritation around the eyes. My suggestion would be to try it, water proof is available as well. If you aren't happy or if irritation does occur, then return it. No one will give you a hard time.

Why did you stop making brown definicil mascara?

I am blonde and like the less harsh brown color? I have used your brown mascara for over 30 years. Do I now need to change brands to buy brown? Disappointed!
Asked by: Anonymous
I'm a blond as well and have used black and brown mascaras and I really don't think there is a difference. The definicils black is not like the blackest-black it is a more natural look. Maybe use one long stroke so you use less (shouldn't have to use a lot with definicils) instead of several coats or if you need more try using the cils booster first it will help build volume without using more mascara.

The mascara I have is definicils noir infini. Is that the same as deep black?

Asked by: DMDK
Yes the Noir infini is what is referred to as "blackest black." I personally love it to go with a night out on the town or to top off the smoky eye look.

Why has Definicils mascara price gone up so much throughout the years and the tube with less mascara in it?

I have bought "Definicils Mascara" for over 15 years and while I have noticed the price go up on the tube...I also have noticed that my tube dries out much quicker than when I first bought it many years ago!!!!!!!!!! Ugh !!!!!!!!!!! I purposely bought Definicils at many different stores just to see if I was correct in my findings...and I was. I really wish for the expensive price of this mascara...that you put back the amount of mascara that use to be in the tube !!!
Asked by: GolfLady
I find that when the mascara gets oldish - I take a paper towel and clean the wand completely and when I insert the wand back into the mascara it seems to me to be like a new tube. I also try to not leave the wand out of the tube too long and to not push the tube in and out to get more on the wand. I have worn this mascara for 30 years and yes it does go up in price but it is the best mascara I have ever found and since it does cost more than many mascaras I think my tips above make the tube last longer. Hope this helps.

cleanse easily with soap & water?

Is Definicils easy to remove with just soap & water?
Asked by: mac76
Yes, mild soap and water easily removes this mascara. It is water-based, so harsh makeup remover is unnecessary.
