Love how my lashes are starting to look longer and fuller!! As a makeup artist and advocate of treating your Jason Wu's Lash serum will do just that! I've used this lash serum for a few weeks and have seen my existing lashes grow a bit and at the base it looks slightly fuller. Other lash serums or treatments I have used in the past seem to take a bit longer to see any kind effect but this was noticeable within a week. Always be sure to remove any kind of eye makeup or mascara that may be deep in the lashes before using any kind of serum. Once cleansed I use the wider end of the lash applicator to coat the lashes at the top and bottom. Afterwards use the top of the lash applicator to separate the end lashes or concentrate the serum in the base of the lashes. I used this product almost every night and love seeing my lashes grow! **This review was created through an educational promotional event hosted between the brand and beauty experts.**

In 4 weeks, I have seen a difference in the strength and length of my lashes. Let me start from the beginning. I was a drag performer for many, many years, often getting home late at night after drinking. I would tear my lashes off of my eyes and quickly wash my face before I passed out on the toilet. Years later, my lashes were thin, sparse, and depressed. I have tried many lash serums over my 22 years as a makeup artist. The Jason Wu, The Lash Serum, is formulated with multiple actives that stimulate growth and condition the lashes. One of my favorite features is the applicator. It is genius. It allows you to use the ballpoint to deposit the serum on the lash line gently and a spoolie to brush the conditioning serum on the lashes. This is especially helpful for me and anyone with very shaky hands because it gives me better control, and I dont feel as if I'm going to poke my eye out. Pro Tip: Water-proof or long-wear mascara can dry out your lashes. The Lash Serum will help add moisture and prevent breakage caused by daily use of water-proof mascara. **This review was created through an educational promotional event hosted between the brand and beauty experts.**

As someone who has been in the beauty industry for 10 years I've gotten the opportunity to try many different products over the years. I have struggled getting this one spot in my brows to fill in and grow in thicker. When I saw that this product could be used on both brows and lashes I knew this was my opportunity to try! I use this at night and brush it through my brows just as you would with a brow gel. After using it for almost a month I can truly say I've seen so much growth in my brows! I'm so impressed with how quickly it works! It's so easy to use and doesn't leave any residue or leave your brows feeling heavy. This being said I believe that with any of these products you need to be consistent with use in order to see results but if you are you will get amazing results! So impressed and stoked with this product! **This review was created through an educational promotional event hosted between the brand and beauty experts.**

Jason Wu Beauty The Lash Serum - NourishmentThis is my first time using a lash serum product. I recently took my lashes extensions off so I figured what better time then now to try. My first impression is that my lashes look and feel soft and heathly. It's been about one week of me using this product every night.Usually after I remove my lash extensions my lashes tend to look a little sad and dry or something I notice a lot of fallout lashes. I also have been trying this lash serum on my brows as well because I'd like them to look fuller. Since using this lash serum I haven't noticed much growth but I have notice both my lashes and brows look soft and heathly is it amazing ! I would recommend this product to anyone who is taking a break from lash extension. **This review was created through an educational promotional event hosted between the brand and beauty experts.**

I've been in the beauty industry for over a decade with experience as a nail technician, a consultant for beauty brands, and more recently a make up artist. That being said I have tried maybe 4 other lash serums. While this isn't the only one I've tried that works I can definitely say I LOVE the application brush for this product and I've never seen results quite as fast. I've only been using this product for 3 weeks and my lashes are longer, thicker, and feel more… I guess silky for lack of a better word. I love the tip on the application brush for your water line it makes applying this such a breeze. I actually look forward to applying it now because I can see it working more and more as the weeks go by! I love how quickly it dries so it can apply the primer and mascara in just a few minutes so even if I'm running behind it's worth the extra step. the packaging is also very cute and at this price point I would prefer to lash extensions ANY DAY. **This review was created through an educational promotional event hosted between the brand and beauty experts.**

As we age, our lashes and brows can thin and in my case my eyebrows have become unruly. I've tried lamination, but it dried out the hairs. As a consumer, I looked forward to trying any lash and brow serums. As an esthetician of almost 30 years, I'm not a fan of the original brow growth serums that contain prostaglandins. They give great lashes, but  affect the ocular pressure of the eye and can sting if gotten into the eye. Not something I want for my clients or myself. Jason Wu Beauty's The Lash Serum is in the newer class of kinder gentler lash care. I enjoyed using this, no tinging or irritation at all. I used it on moth lashes and brows. I haven't noticed that my eye lashes are any longer or thicker, but they are well nourished. No fall out! My brows look much healthier, and I did notice I had to trim them more. I will continue using the product to see if my lashes get thicker and/or longer. If not a dramatic result, this a great nourishing product. **This review was created through an educational promotional event hosted between the brand and beauty experts.**

So I have been looking for a lash primer for so long that not only makes my lashes longer but thicker. I have used this lash serum every night oh no idea and honestly I have not seen much of a difference. My lashes feel very nourished however, I feel like the Jason blue lash primer does the same thing. I really wanted to love this, but I honestly have not seen much of a difference, and I am a person who doesn't even wear mascara generally because I feel like my lashes are so thin they look better just Curled. So as I was using this at night time, I was using the primer in the morning and mascara with it and I saw no difference in my lashes. They just looked thin and spacey not any thicker not any longer, but they do feel soft.I don't think I would buy this again and I don't believe I would recommend this to a friend. However, the Jason Wu lash primer I liked a lot. **This review was created through an educational promotional event hosted between the brand and beauty experts.**

I'm a beauty professional with over 12 years experience in hair/skin care. When it comes to hair health I'm all in. I couldn't wait to try out the Jason Wu Beauty The Lash Serum - Nourishment. First off, I loved the pretty color of the tube. You'll want it sitting out, it just looks happy! And the applicator is 100. In love with the spoolie and tail tip. Couldn't be any better! As far as the product- here goes. It's not the best serum I've ever used, but it's not the worst. I have very sensitive eyes and I was super pleased that it didn't irritate my eyes in the least. You can use it at night, or in the morning before your primer or mascara. I've used it both ways and I prefer night time use. I haven't noticed any growth, but I haven't noticed shedding either and that's always a plus. I'd like to give it more time to see if I can see a bigger difference in a few more weeks. **This review was created through an educational promotional event hosted between the brand and beauty experts.**

I've honestly never heard of this brand before so I was pretty excited to try it out. Starting out my beauty career as a makeup artist I'm always interested in trying new brands and especially ones with nice price points that are attainable for most people. Just because it's a good product doesn't mean it needs to cost a million dollars right? I was kind of hesitant of using a lash serum that's not medical grade or prescription strength but I'm a medical aesthetician so maybe that's why. I didn't really have high hopes or expectations for this product. One, I already have long lashes and they are pretty healthy. Two, we really didn't have enough time to really test if it was super effective. I do feel like it was hydrating and I did like the feel of the product. It did not irritate my eyes like some other serums have in the past. Other than that I didn't notice a difference. **This review was created through an educational promotional event hosted between the brand and beauty experts.**

I'm so thrilled to finally be trying out the infamous Jason Wu cosmetics. Some of you might be more familiar with his exquisite fashion line. Either way, you are safe to expect high end quality results with anything JW related.As someone who has always struggle with my short, straight and thin lashes, I'm always on the lookout for the next best thing to help them out. When I came across the Jason Wu Lash Serum, I couldn't wait to try it out.This serum's applicator is so unique. Not only does it offer a wand, but a small sponge tip as well for harder to reach areas. I'm a sucker for multipurpose products so I especially love that you can use this both under your makeup as well as a night time treatment. It also contains biotin which plays a huge role in hair health, growth and strength. I'm thrilled to say I noticed an improvement with all of the above.Pro tip: Works great on brows as well (using the sponge applicator). **This review was created through an educational promotional event hosted between the brand and beauty experts.**
