Most Helpful Positive Review Flawless skin! 😍😍 I've been using this for serval weeks now & the results from using just this one product & my regular moisturizer has been amazing. I was skeptical at first because I've never had good reactions to vitamin c serums in the past but decided to give this a solid try anyway.
To give this product the ultimate test I decided to cut out everything in my skincare routine except for this serum, my cleanser & moisturizer to see what the results what be... OMG!!
For reference I have (or had;) sensitive oily combo skin with extremely large pores around my t zone that would turn into an oil slick after applying any skincare or makeup products.
After using this product for nearly a month, my pores went from HUGE craters to being normal, barely noticeable & my oiliness is almost completely gone even after applying makeup!!
I am soo beyond trilled at the results and will be buying this from now on! I never want to run out, ever! It makes my skin look flawless even with no makeup on, plus my makeup apply's more evenly & looks flawless. No more filters needed on my pics 😍😁
My skin is overall brighter, smoother, my fine lines are nearly obsolete & my pores look amazing!
My only complaint is the smell is kinda off putting, not sure what it is but it's not a pleasant smell. It isn't so bad that I wouldn't use it or buy it again & it fades quickly, but it definitely has a unique (not in a good way) smell.
For me this is no longer an issue since I've been sick with C***d for the last 2 weeks & have lost my sense of smell :/
And while a minor complaint, I don't like how the directions say to use "4-5 drops" but it has a pump dispenser which makes it very hard to dispense just 4-5 tiny drops so I've been using about 2 pumps which for me is my golden number, any less & it's not enough for my whole face, anymore & it leaves my face too sticky. So you'll have to play around to find the right amount for you, just don't use too much because your face will be SUPER sticky.
Overall, I give this product a 10/10 & would definitely HIGHLY recommend to everyone!!
I included a pic of me with zero makeup & no filter taken a days before I got sick 2 weeks ago & my skin has only gotten better looking in the 2 weeks since because even feeling like I'm dying & barely being able to move, I still made sure to cleanse my face & apply this serum almost daily (mainly because I've lived in the bathtub for the last 2 weeks lol).
Most Helpful Critical Review Am I brilliant with Bye Bye Dullness? I've been reading a lot of great things about vitamin C infused face serums and was THRILLED to be trying the Bye Bye Dullness from one of my favorite beauty brands, IT Cosmetics. I received a bottle to try and review of the product from Bzzagent and immediately began trying this under my foundation in the mornings.
I've tried two other Vitamin C or Niacin infused face serums in the past that I purchased on a whim since they were a bargain. One common thing I've found with vitamin C infused products is a very foul smell. Unfortunately, this was no different. I suppose I'd expect a fresh citrus kind of scent, but nope. I have to hold my breath while applying.
Unlike the other products along this line I noticed is the consistency of this. I wouldn't call it a serum per say. I usually think of something viscous and thicker. But, this is very liquid. This means it absorbs very quickly into skin and doesn't leave any kind of sticky residue. I can immediately apply makeup and let it do it's work. I wasn't anticipating the product being so thin, but it was definitely nice for it not to slow me down in the morning.
After about a week I did notice that my pores were smaller and the texture of my skin was noticeable improved. But, I wouldn't say it was necessarily less dull, which is supposed to be the point of the product.
Overall, I have kind of mixed feelings about the Bye Bye Dullness. It did improve my skin texture and reduce the size of my pores. But with the odor, cost and lack of actually brightening up my complexion, I don't think I would be running to this product as a staple in my routine.

I am really disappointed in this product. The serum is extremely watery so it's difficult to get onto the face as it runs off your hand, fingers, and face. Because of the consistency, the pump makes it very difficult to distribute. It probably would work better with a dropper. It also has a terrible smell. I've only been using the product for 2 weeks so I cannot say how effective it is but so far I have not noticed any difference in my skin.
I'm going to give this a 2 star rating 2
Bri from Washington Sate
Hey Everyone so I bought this product to help with my skin right. first off let me say I loved It cosmetics I use there Night cream, moisturizer, and eye cream. I'm 27 I have fairly good skin. I just wanted to make sure I keep up with my skin care as much as I can and start early then later. right ? Well I bought this product and it was great for about 4 days until I noticed my skin started to get bumpy (like pimples forming) i hardly every get pimples and when I do its only like one. But I started forming ALOT.. When I used the product I noticed right away its sticky when it is in contact with your skin and it feels like a bit stiff and it says to use your moisturizer after and so I did. I kept on using the product but my face doesn't feel right or what it was naturally like so I stopped and my skin is getting better. I honestly don't like the product or recommend. it really does sadden me because I never had any complaints with the brand and some of the products. Now I'm pretty skeptical about buying anything more. :(
It is not what I expected 2
Tori from Cary
I love IT Cosmetics, but this Vitamin C serum not their best: too much alcohol ( and u feel it), spreads hard, strange smell. For the price yes, you may not expect same as 90$ serums, but for me it is little bit harsh because of alcohol.
Just meh 3
Amy from Seminole, Florida
I really wanted to like this product as the price point was what I was looking for in a vitamin c serum however, I am disappointed. It comes out of the bottle very liquidy and as soon as I applied it, it didn't spread. It basically just stayed where I put it initially (two areas on my cheeks and my forehead). I then put my Clinique Moisture Surge over it and immediately noticed where I put the vitamin c serum, was sticky. I could also tell it only went exactly where I first touched my face. I then noticed the smell was off. It could be the combination with my moisturizer but it had almost a latex smell which is not something I want on my face all day. I will be returning this product in hopes of finding something that works and smells better.
Too runny 2
Wini from New York
This product has potential if it was produced in a different consistency. It's way too runny for my liking. The bottle and pump are great but it was even leaking through the pump part. It goes well on the skin and does the job but it's a hassle.
Would not recommend 3
Jay from Chicago
I'm still in the first few weeks of using this product. The stand-out feature is awful packaging. It leaks terribly. The instructions tell you 4-5 drops, but it's a pump, so that's confusing. I'm still in the early testing phase of this product, but I think it's leaving residue that leaves black heads on parts of my face that normally are clear. So far, it's fine and I won't return it, but I'm leaning towards never purchasing again.
On the fence 3
Mommaof3 from Medina ohio
Have been using this for a week now and do not see a lot of difference in my skin. The products is extremely runny and it smells like fermented fruit. Keeping but not sure I will purchase again. Not worth the cost in my opinion. I do overall love IT cosmetics.
Burns, watery, smells bad 1
Holls from Los Angeles Ca
The consistency is so watery for type of bottle it comes in. It hurts my skin makes my skin very red and itchy. It smells horrible. Like chemicals. Not worth it.
Good but learning curve 4
Addie from Columbus, MS
It gets the job done. The comments aren't wrong. It does come out in a leaky fashion. It's sticky and smells odd. The instructions say 6 pumps. my recommendation is to mix it in a small container with a gel moisturizer. problem solved :) naturally tightens and lifts while brightening dark spots and acne scars. cocktail it in a separate container with your confidence in a cream and you're set!
Liquid Mess 3
Jen from Oregon
This is a sticky liquid that pours out. The instructions say to use a few drops,, but that is impossible. You get a handful that runs through your fingers as you desperately try to get it on your face before it is all gone. I don't know if it works as I returned it when I tried it.
Best Vitamin C ever! 5
Joe from Charlotte
I love the radiance this gives to my skin. It only takes a "tiny" amount. I use it on my clean fingertips and press into my skin, let dry for about 1 minute. I am using the bye bye lines on top and my skin has never looked better! Also, when I wear my foundation it goes on so much smoother!
Will not be buying this product again 3
Maria from Apex, NC
Every time I lift the cap, the product pours out… not sure why… so messy. The pump system is not working properly causing mess and waste of this product

Searching for a Vit C product 4
Pama from Albuquerque
I wanted to find a product with Vit C. Haven't used this long enough to tell. I don't know if this should be so much a liquid and not a serum, which seems odd
Not impressed at all. Will be returning. 2
Liz from Pleasant prairie
Did not like at all. Cheep dispenser that barely works. Product has extremely low viscosity and runs between your fingers before you can apply to face. Left my face with peels. Do not buy. Not worth it.
Hard pass 1
BangieB from Houston, Tx
I bought this with high expectations, as I love IT products. Very disappointed. First, the pump delivery system is terrible. More product is wasted in my hand than I can get on my face. The product is thin vs a serum type consistency. It also burns and irritates my skin. Haven't noticed any significant improvement from the less expensive Vitamin C I used previously. Will NOT be purchasing this again.
Nope, pass on this one 1
NDT from MN
There's something sketchy about this serum. It smells terrible, very chemically, and has a sketchy color, like it's gone bad or is old. Can't forget to mention how it burns when it goes on and causes my skin to react, and I have pretty hearty skin. Believe the bad reviews and save yourself, and your precious skin, from this serum. You can do better, IT Cosmetics.
Sticky and smells bad 1
DaniGirl from Colorado
I love IT products. My dermatologist recommended using a vitamin C serum and I tried this. Wish I could return. Not only is it sticky but it smells! It is a brown color also. This one is a hard pass for me.

This product is super watery and the top of the bottle leaks. It leaves my face sticky. I love IT products and I really wanted to love this but I will not be purchasing this one again.

This turned after 1 month 2
Ashley from Iowa
This started out fine, but after about one month it started to smell like alcohol. Then it started to burn my face and make it sensitive. I had to discontinue use.
Sticky on face 1
mali from Miami
I did not like it at all. Makes you feel sticky
Very strong serum 2
Zp12 from North Carolina
This serum was a bit too strong for my skin. After applying to the skin it began to burn tremendously. I had to wash it off.
No difference 1
T&co5611 from California
I just finished the bottle and don't notice any difference in my complexion. The product itself smells like vitamin c but is very sticky.
Outstanding 5
RubyRed$5 from Atl,GA
I am absolutely stunned by Bye Bye Dullness. I recommend everyone try it. It does things for me in a way that my usual brand doesnt. The comparison is outrageous. I am already purchasing more because I use this everyday !
