Falyn L. Using it twice per day for a few weeks. Noticed significant dark spot fading and maybe even some pitting disappearing.

abdul h. I haven't used it for long but I am happy with the product so far.

Vava M. very good

Quynh H. Beside fix scars, Niacid is best skincare which I persistently used twice everyday. Smallize pores, lighten tone, . worth it

Daryll S. Slurp it is! Works very well with me. Thank you Slurp Labs!

Angela R. Liked the product very much. It had a good consistency & feel. Made my skin look like glass. Had a few compliments! I also used it on my scar tissue as it was gentle but effective & didn't make the skin sore.

Eeva S. I am super happy and pleased with this product! My skin is much more fresh in daily basis and scars have started to fade. Also other people have noticed the difference and have commented that my skin is looking better and healthier nowadays. Thank you!

McRomel C. I really love Niacid❤️ Will order more

Jasper L. It is really nice to use I have used for the 3rd bottle, the scars improved significantly... it worth to try

Errin G. My skin is ultra sensitive and breaks out .. everything I’ve tried has made my skin worse so when I found this product I surely was skeptical. However, I still ordered it and to my surprise it worked and hasn’t broken me out. Been using niacid for about 6 weeks and I can’t live without it. This product has also allowed me to cut back on my skincare regime. I only wash my face and then apply this and I use moisturizer on my eyes. Best thing ever. Will be ordering more. This bottle is at the half way mark and it’s been a month and a half so I’m guessing it will last 3 months to maybe 4 and that’s using it twice a day.

Michelle G. This stuff is magic!!! I started using this back in May and it has made such a difference in my skin related to evening out skin tone, reducing length of pimple, smoothing skin surface. 10/10 recommend. Buying more as we speak

alessandra z. Super

Nguyen A. This help many dark spot disappear^^

Erick G. Awesome product for real.

I-Lin L. I was going through a crazy allergy period just last week, my face was covered in red rashes and I was a bit hesitant to use niacid, but I’m glad I did, not only did it not irritate my sensitive face, it also helped improve my rashes in just days! Heard it works better with hyaluid so that’s exactly what I’ve been using, so far both has been working out fantastically for me! A little also goes a long way, will definitely repurchase in the future!

Sina S. I have used this product before as they promise that it would help your acne scar. But seems like my scar just getting shallow but didn’t disappear. However, other things happened in a good way on my skin too. My acne was reduced, pores were smaller, and my face looked brighter. So, I think I will keep using it anyway but this time I will use it while I’m doing derma stamp on my face.

Pou-u O. It's still a bit too early to see a big difference but I do feel less oiliness in my skin. I had a lot of piting from my acne but it seems it's a little less prominent now. I think I will definitely see more of a difference as I keep using the product. I'm very happy with it thus far.

Ka Y. I have a oily skin with blemish. It smoothen my skin a lot.

MARKELLA F. perfect!!

Rachel L. It’s a good product that works but requires time to show improvement

Cer S. Fell in love ! ❤️

Sing K. I had very serious acne problem because I was not aware of skincare regime. Exercise under strong UV without sunscreen, no toner and moisturiser applied. Confidence was low when approaching people. Since using Niacid from May 2019, no more acne and pimples breakout. Facial sebum is under controlled. Left 20% of acne scar visible in close distance. Should be 90% recovery end of this year.

Karen F. Love it

Jacklyn F R. This product is amazing like nothing I’ve ever tried before. After just two weeks my acne scars and fine wrinkles have smoothed out considerably, blotchy spots and redness gone and large pores much much smaller. No more oily and dry areas, finally balanced. Great product, love it.

Teresaann T. this is amazing on my skin ❤️

Sonia S. Thank you Slurp for this magnificent product, I have been using it for two weeks and my skin feels soft . Thank you Slurp

Eunhye J. Amazing

Alevia Z. Bought two bottles - my aunt uses this for her pigmentation and it really helped her. I use this for acne and pores - seems to do the trick!

Joanne T. Within one week of use, my acne marks slightly faded and my skin is a lot smoother

YERUSALEM T. I LOVE THI PRODUCT IT REALLY WORKS I HAVE VERY PERSISTENT SCARS I AM USING MY THIRD BOTTLE I LOVE IT

Laura J. Amazing!

Binita C. My skin is changed. From feeling hideous, low-esteem and lacking confidence to getting comments on my impoved glowy skin, niacid has really helped me overcome the skin problems. Keep patience and give it a try !

Leilani A. I didn’t experience an instant result on this. Since My skin is so sensitive, I have experienced bumps in the first 3 weeks of using it. It was so bad that I even decided to stop applying it on my face. Good thing I didn’t and just stayed with it. After almost 2 months of using it, my skin started to react and absorb it. I can now see the difference from how my skin looked before Niacid. I have deep scars from acne and I see that it’s way better than it was before. It hasn’t fully faded but I can see that it’s getting there. I can’t wait how my skin will fully transform as I finish the whole bottle! My first order arrived really fast but got stolen due to irresponsible drop off from courier Delivery. I messaged their customer service and received a response immediately. They sent me another bottle with a complimentary Hyaluid and shipping! Nothing can beat that!❤️ Overall, I’m so happy with this product and their customer service. I will repurchase once I’m done with my bottles. It’s more than 2 months now and there’s still a lot left to use. I can’t wait for more great results as I continue. Thank you so much Slurp Laboratories!❤️

Trany N. My acne’s scar getting better

Quynh H. The new formula of Niacid seem to increase the rate of purging. Although purging is detoxification for skin but not many ones like to suffer it

Ruth A. I had terrible acne as a teen and you g adult. Niacid has drastically reduced my scarring and I’ve only been using it for 30 days. Amazing product!

Elizabeth M. nothing happens with my skin. still totally the same

Tajzan S. I was a bit skeptical in the beginning but omg.. what a product! I saw difference on my face after couple of weeks. Incredible! I ordered to Finland and it’s worth every penny!

Wynner N. Been using this for a little over a month now and I can say that it is working. Dark spots caused by acne definitely got lighter and shallow scars got barely noticeable. Using this until my deep ice pick scars disappear.

Sima G. Didn’t work for me

Ava B. after 1 month i saw a drastic change

Michael C. This is an amazing product that really helps. I was skeptical at first, but I am impressed and happy. Thank you

Mabel N. Just finished my third bottle in 6 months. I have many deep old scars on my cheeks, and while they have not disappeared, they definitely look less deep, and skin tone has already improved significantly. Hopefully will have more improvements to report soon.

Anis M. Decided to purchase Niacid seeing all the great reviews. It has been about a month since I started using it. Initially I stopped all my other skincare and use just this, to make sure it doesn't cause me any breakout. After a while I noticed my skin got clearer, no active breakout whatsoever even during that time of the month. This is quite rare for me. So all is good. A few days ago I decided to introduce back my other skincare into my routine. Big mistake! Immediately got a few active acne the very next day. So I stopped my other skincare hoping Niacid can fix it again. Only if I found Niacid earlier. Could have saved a lot of money and time. Please don't stop producing this.

RUTH R. This is the first time I write a review. I had try everything possible for my acne scars from fillers, skin pen And everything between, some of these procedure helped but the effect was gone soon. I could see a difference in my skin in 4 says, I couldn’t believe it. I took pictures and sent them to my daughter to make sure I wasn’t just seeing what I wanted to see. This product works, it’s amazing!!!

Xinting L. Have been using for two months. It does lighten pigment from acne and reduce indentation. Will keep using it until the holes are gone.

Aralica S. Started to use it not so long ago, seems ok, but need more time for results.

Jestony G. It will absolutely lightened thus reducing the depth even your old acne scars...

Kirnjit T. This product helped my acne scars and rosecia as well. Ever since I’ve started this, my face is less inflammed, red and lighter scars!

Ranjini E. Was hoping Niacid would have shown improvement on my acne scarring, but so far - no results. To be fair, I’ve only been using it for about a month, morning and night and I’m not yet half-way through the bottle. Hopefully will see a difference after using the whole bottle- but based on other reviews, I am disappointed that I haven’t seen results by now.

Gagandeep K. It's good result is better but not perfect may be after a month let see ....

Maxwell R. Very good!

Cyril E. This started to minimize my acne scars!

Yvonne J. I had very bad maskne and pigmentation from maskne. I started to use Niacid since 2 weeks ago and the effects amazed me! My face is less inflamed, no more new maskne and reduce pigmentation! Definitely will purchase again in near future.

Diana B. I was suffering with a kind of rash on my face, so I went to many doctors to check that up but they could help it. It has now finished with this. It is just amazing.

Jaennevibe C. I have been using Niacid for over a year now and it never fails me.

chua x. Already at my forth bottle and I must say my daily skincare can’t go without it anymore! I was previously struggling with bad acne marks on my face and my skin has improved drastically after I started using Niacid! So glad I found this online.

D M. I recently bought Niacid following a controversial facial that left me with scars and hyper pigmentation around my eyes -- it was a nightmare! I tried aloe vera and shea butter, and although it did help, I was self-self-concious to leave the house. Within a week of using Niacid, I noticed a significant difference, not only in the texture of my skin, but the pigmentation was going away! It has been an added bonus seeing my enlarged pores around my nose shrink. If you are on the fence about buying this product, I definitely say give it a try! As soon as I finish this bottle, I'm trying Slurp's other product. I'm a fan of this brand!

Laurence G. I have been using Niacid for over 2 months. My redness on the face has completely disappeared after a month but I am waiting to see its longer term effects on my hollow scars

Cesar F. It works very well on my scars. It takes time and patience, but you can see the results.

Melvin M. We think it is a great product,and the such a amazing SLURP TEAM. Wow..after the 3 bottles,I hope I will come back looking more younger in my 40's jajajaa. Thank you so much SLURP.

Jayden A. This product is amazing, I bought the product two months ago as you can see I don’t have much left in the bottle my face indentions have lifted dark spots have faded my face is more fuller it’s smooth and clear I mean I can go on all day about this product I’m about to order my second bottle because I can only imagine the results after I finish the second bottle coming from the face I had before just two months ago, I want to thank everybody at Slurp company all of the staff, customer service you guys are amazing. I’m 34 and my skin is looking maybe 22 can’t nobody tell me nothing oh iam using other products as well but I’ve been using them forever and since I’ve been using Niacid everything has made a drastic change really fast. Thanks again

Jagoda N. Couldn't be happier with this product! First thing I noticed after just 2 days was that I don't have to reapply my moisturizer 5 times a day! My skin feels so much more hydrated and protected. Then after a week parts of my face started smoothing out that I didn't even know were uneven because I was focusing only on my deepest scars. It really boosted overall impression of my skin and the whole face. Also, my skin is not as red as it used to be. Nothing else helped with that before! I finished my first bottle now and starting second. My deepest acars are still there but they are slowly and steadily filling out. Which is amazing and kind of surprising if you consider they are about 10 years old. I really can't wait to see any new products this company releases! This is the kind of product quality worth my hard-earned money. Also, everyone working for customer service are absolute angels!! ♥ I don't know how much they earn but they need a raise anyway! Customer service is something that can completely make or break whole shopping experience. And the help and support I received here was truly magnificent! Sencirely, Forever-return customer

Chanelle D. I have tried so many products just to be disappointed by the results. The niacid has given me clear skin for longer than i have ever had before. I have no redness or inflammation, no cystic acne no purple marks from where the Acne used to be. This is definitely worth it! Every cent of your money worth, just try it.

Jasmin T. Works well

debbie s. Been maintaining my clear face with this! On my “nth” bottle alreadyyy!

Aron F. I’ve been using it for 5 weeks and lots of my scars have improved a lot. I can’t wait to see the results after longer use. I recommend this product to anyone who has acne scars.

Sakina G. Miracle in a bottle - love LOVE Lovvvvvvvve this product

Yuan Shen N. Great stuff. Lasting me for quite some time now. My facial scars are fading albeit very slowly. Looking forward to using it for the longer term.

Lorena E. Good and effective

Pauline W. Noticed a difference in less than a week, will for sure re-purchase and will probably use forever!!

Stephanie R. Definitely notice a difference in pore size. The good skin is better. Not sure I notice a huge difference in bad areas.

Aistė K. I've used Niacid for 2 month, my skin looks better even do I didn't have big acne scaring. I really love it, I think I found my number 1 skin product :)

Maria S. I figured I may as well stop the usage of Niacid after applying twice daily for a year and a half or so. So I stopped for 2 weeks. Big mistake! It's not about the acne scars, since I really don't have them anymore. It's about the overall appearance of the skin, the brightness and the "glass skin" look. Only Niacid keeps that glow going! I know now to continue using both products Hyaluid and Niacid if I want to keep having healthy skin. I am amazed every single time I apply them!

Bryan B. It’s works like a miracle!

Javier R. Muy bueno

Lulu L. It a good product to use it! Tq.

Nikkazia T. Helped a lot in my scarred face. Im on my 3rd bottle. I have an unopened one as a spare. I am using it forever i guess

Romina B. I used to have a lot of marks on my face due to pimples. But is getting much better I'm 29 years old and people usually tells me that I look 23.

Serena T. Works wonders on my skin! Makes my skin smoother (unexpected) and visible improvement on the acne scars!

Melkhin M. The Fountain of Youth

Nhuy V. This is truly amazing, my toothpick scars are really getting smaller, my face looks more even now. The first couple months, it didn't really make any different, I was a little disappointed, but I started noticing a big difference after 4 months, I am really happy that I bought two more bottles. One complaint I have is that the dropper doesn't extend all the way to the bottom of the bottle, so there's quite a bit of liquid left, you have to work hard to get it into the dropper, so if Slurp could extend the dropper to reach the bottom of the bottle when it's closed all the way, it would be perfect

bao d. I'm half way through my first bottle, so it isn't really fair to give a review quite yet. However i keep being ask to give one, so here you go: - I do love how my skin texture have change, it appears more smoother, however i do use lots of other products, so again, i'm not sure of the effectiveness. - My skin tone do look brighter. -The purpose of me purchasing this product is to eliminate my stubborn acne scar that i had for years, so far not much have change quite yet. - I ordered 2 bottles, probably end up order a couple more as i want to give this product a fair chance. I will post an update review after i give it a try for a year or so.

Carol L. Awesome

Kor J. Love it and not oily

Nadav G. This stuff truly works wonders. In a matter of two weeks I saw previously enlarged pores begin to shrink and acne scars show early signs of smoothing out. I highly recommend this product!

Kathryn H. I’ve been using niacid & hylauid for a little over 3 weeks now and have seen a very small change in the texture of my skin. It appears to be retaining moisture longer and in the morning my face feels dewy. Going to continue to use the products & hopes to see more dramatic results

Joury O. I’ve been using it for 5 weeks and lots of my scars have improved a lot. I can’t wait to see the results after longer use. I recommend this product to anyone who has acne scars.

Sophia-Electra E. It is still very soon but my scars have improved. They are not that like deep anymore. Nothing before has helped them. Now I’m ready for laser or peel. I’m sure it’s going to be a huge success my new skin.

Chui F. Great product for my Bumpy skin

DAISY A. My skin texture is better and pores look smaller. I've had cystic acne most of my adulthood. And though it's not as bad now, I was left with scars and must always cover it with make up. Saw improvement into 2 weeks of use. First time in over 20 years that I can go out make up free

Samantha r. Definitely helps with scars and active acne. I use it everyday!

Monica S. I love this product. It sinks in quickly and has retextured my skin. This is my second bottle. In the first darks spots that were only a few months old quickly faded away. Now, some that are 4-6 years old are starting to fade. I am sure they will with another round of treatment.

yasmin n. It’s done wonders for my under eye area! My circles are barely there. I love it!

Alisa N. Didn't help me. My skin has an acne breakout now and my skin was better before using it. I had so much hope in this product since it was so expensive.

Ioana P. my skin is very happy with this product. i will come back for more for sure

Amanda B. This product works wonders!

REHANA I. I am on my second bottle of Niacid and Hyaluid. It has been almost 2 months and so far, I am very happy with the results. I have had a significant improvement in skin tone, pores and fine lines. My major concern were some open pores on my nose and cheek (old acne scars). I had tried most products and treatments with no reduction in pore size. After just 2 weeks, the pores shrunk by half. The smaller ones are more refined and, the 2 largest ones on my nose are reduced by more than 50%! I apply the serums on my neck, décolleté and back of my hands too!! It has replaced many other Skincare products in my beauty routine. I love the Slurp products. To me, it is reverse ageing in a bottle!

Bryan E. I’ve been dealing with acne scars from my teens, and I tried everything - dermabrasion, chemical peels, subcision, TCA cross, fractional CO2, RF microneedling... with limited success. I am now on my third bottle and no other product or procedure has made this much impact on my acne scars!
