BL Lashes Black Diamond | Lash Sealant for Extensions — Extends Fills to 3-4 Weeks | Dark Mascara-Like Finish, Waterproof Coating, Brush Applicator (0.24 fl.oz)

I absolutely love this product! One of the most unique features is the bottle does empty at the end of use! Therefore, you use every bit of product. Always shake well before every use! Very good for individuals with sensitive eyes! Hope this helps!

I go for a refill every 2 weeks. Before using this, 90% of my lashes were gone by refill time and it took 45 minutes or more for my 2 week refill. Now, around 40% of my lashes remain at refill time and refills are taking 30 minutes.

I use this to seal the glue with my lash clusters. All the glues that I tried to came with the glue and sealant as a combo, would leave a white residue. This seals my clusters great and is easy to apply.

seems to do the job it's made for. I apply it in the evenings or mornings after I wash my face. It has a very light charcoal translucent color to it but doesn't stain skin. easy to wipe off. My eyes don't sting when using it and I wear soft contacts. it seems to make my extensions go longer, which is what I wanted. Bonus- helps groom the lashes back to their proper position, although some did clump with the coating. I just brushed with a dry eyelash brush to separate them after.

I don't usually have the time or motivation to leave a review, but I am so pleased with this product that I had to make the time. I pay a small fortune every two weeks to get my eyelashes extensions applied, but still by the end of the two weeks the ones on my right eye are almost always gone. I think it might have to do with the side I sleep on and rubbing my eyes inadvertently when I sleep. Two things have helped tremendously. First and foremost this sealant is working wonders. I'm only two days away from a touch up and I have most of my eyelashes, even on the right eye! Two, I wear a sleep mask now. No more rubbing my eyes while I sleep even if I want to! Finally, regarding the sealant, another issue I had with eyelash extensions was keeping them completely clean and neat, i.e. after a few days different eyelashes might start pointing in different directions, etc. This product is not only great for keeping my eyelashes on, but it's also great for grooming them to look like new.

Didn't really see much of a difference but I only use this because I put on eyeshadow and it leaves dusting powder on my lashes and sometimes the powder sticks to my lashes and gets dusty so I put on a few coats of this on to just clean up the dust and it does gloss it over but I do have to wash it off at night or it will build up after time. I do wish it a as a bit darker since it's pretty watery and you do have to put a few coats on to notice anything. And if you put too much then it makes your lashes clump together and you'll have to separate them with a brush after.

Ok, I finally tried eyelash extensions for the holidays. I love the look but I don't like the upkeep. I purchased this black diamond coating and saw a huge difference from my first fill to my second fill. The first fill I waited 2.5 weeks before I had the fill and I was not using this product, now I am at 3.5 weeks and credit this product for my lashes still looking so great. I put it on in the morning and it straightens out my lashes very nicely. I let the product dry and then gently brush out the lashes with a dry lash brush. I don't know how long I will keep the eyelash extensions. I don't like the itchey feeling I get sometimes and I don't like it that I can't wash my whole face and use all the eye shadows I like to play around with. I think I'm going to TRY to find a eyelash serum that really works and will grow my own lashes! The trick is finding one that actually works!

I am so disappointed in this eyelash coating. I have been getting eye lash extensions for over a year and usually go 2-3 weeks in between refills. Someone suggested I try a oil free for my lashes. All of the products my eye lash artist uses are Blink, I decided this coating was probably a great option. I read all the reviews and they were very mixed, but I thought I would give it a try. WORST MISTAKE EVER! I used it twice the first week. I didn't feel like it offered much of a change in the look, but decided to keep trying it. I noticed by day 7 after an eye lash fill, over half of my lashes had fallen out. This has NEVER happened to me. I went in for a fill that week thinking it was a fluke. I discussed the product with my eye lash artist and she was shocked as well. I decided to try again, using it only once during the week. After 5 days, my eye lashes were half gone again! I will NEVER use the coating again, NEVER! You would think the coating would be compatible with the Blink glue used with my extensions, instead it is like it breaks it down. This one little product has cost me $320 in early fills for my lashes. Do NOT buy this!!!

Bought this for my eyelash extensions. Love it. Just what I wanted.

My lashes last longer if I don't use it!!!

Makes my extensions nice and shiny, a little tint (black) and up to now seems as though my extensions have lasted better than expected, will keep using for a few months to see if it is still doing it's job. :)
