Best serum for dark spots

The best serum for dark spots, it feel so smooth and calming. Gentle on skin no irritation and slowly fades pigmentation. Works best with sunscreen.

Beautiful smell, Gentle but effective

Love the quality of this serum. I have a left over dark spot right in the centre of my forehead as a legacy gift from having Shingles on my face (My VANITY!). This serum is helping to fade the spot, been using it for 4 weeks now and my concealer usage is starting to reduce. Hopefully another 4 weeks and my skin care routine will go back to the 5 minute basics again!

Not difference

[This review was collected as part of a promotion.] Every skin is different, but I haven’t noticed much of a difference in mine.

Reply from Consumer Care Center 15 June 2026

Hello Laura MGA! We completely agree that every skin journey is unique, and we appreciate your patience while testing out our Mela B3 Serum. Hyperpigmentation can be incredibly stubborn to treat, and because skin cells renew over a multi-week cycle, it often takes eight to twelve weeks of consistent, twice-daily application to see a visible reduction in deep-set dark spots. To help support your results and protect your progress, we highly recommend pairing your serum with a daily broad-spectrum sunscreen of SPF 30 or higher, as even minimal exposure to UV rays can trigger new melanin production and counteract the brightening benefits of the Melasyl™ and Niacinamide.

Difference in my dark spots

These La Roche Posay products are seriously impressive. The Mela B3 Serum feels lovely on the skin and I'm already noticing a difference in my dark spots. Paired with the Anthelios SPF 50+, my skin feels protected and looks more even toned. It's a fantastic combo for tackling pigmentation and keeping skin safe.

Looks like I've been duped

I really appreciate the Mela B3 product line. It has helped reduce some of the dark and uneven spots on my face. I have been using it for less than a month, and so far I am pleased with the results. With that said, I also purchased another Mela B3 product, the serum. However, to my disappointment, when I opened the sealed box, the contents of the bottle did not appear to be a serum but instead had a consistency more similar to a lotion. I then reviewed the information on your website and watched the video featuring the Mela B3 Serum to compare the consistency, and the product I purchased was noticeably different from what was shown. As a result, I feel disappointed and uncertain about using the product, as I do not know what is actually inside the bottle. At this point, it seems likely that I will have to discard it, which feels like a waste.

I have used this serum twice a day for two months and my Dark spots I'm not faded at all. This is a terrible product!

Reply from Consumer Care Center 03 June 2026

Hello! Thank you for sharing your honest review of Mela B3 Serum. We're sorry to hear about your disappointment and that you haven't seen the results you hoped for after two months of consistent use. Treating dark spots can be a complex journey. Because of this, some stubborn spots can take 12 weeks or longer of daily treatment to begin migrating to the surface and fading. For best results, we always recommend pairing it with a broad-spectrum sunscreen as your last step in your morning routine to protect the skin. We value your feedback and want to help you achieve the best possible results.

Thank you for taking the time to share your review of our MELA B3 Anti-Aging Serum for Dark Spots Powered by Melasyl™. We are happy to receive your feedback and experience. We are sorry to hear that you are not yet seeing improvements. Please note that for discoloration, results should appear within a few weeks or months depending on your skin and the intensity of the dark spots. We suggest using a sun protection while using this serum to prevent further dark spots from forming. We may also suggest pairing it with our Mela B3 Micro-Peeling Gel Cleanser. Combined with niacinamide and exfoliating PHA, this formula helps fight the look of dark spots by brightening and exfoliating the skin.

Amazed by the results!

[This review was collected as part of a promotion.] This is really potent stuff. I can’t tell you how many products I’ve tried on my melasma that have done nothing at all; this one hit different: it faded by about 40% (it didn’t eradicate it but I’m not surprised as it’s my melasma is very dark and I’ve had it decades) the product has a great texture that clings to the skin, but sinks right in without any sticky residues. I use at night to allow it to do its magic. Consistency is key with this, you need to keep using it daily or the hyperpigmentation starts to return again. I always follow up with a good SPF50 the following day to prevent further sun damage. Recommended For reference I’m 50+ with combination skin.

Gentle but effective for dark spots

I’ve been using the La Roche-Posay Mela B3 Serum for a while now, and honestly, I can see why so many people like it. The texture is lightweight, absorbs quickly, and layers really well under moisturiser and makeup without feeling sticky. What stood out to me most was how it helped make my skin tone look more even and fresh over time. Some of my post-acne marks and dull areas started looking softer after consistent use. It also gave my skin a healthy glow without irritating it, which is important for sensitive skin. I wouldn’t say it works overnight, but with regular use, especially alongside sunscreen, I noticed gradual improvement in dark spots and overall brightness. It feels gentle but still effective.

Hello! Thank you for taking the time to share your feedback. We are sorry to hear that the scent of the Mela B3 Serum was off-putting to you. Because this serum is highly concentrated with potent clinical actives like 10% Niacinamide and our multi-patented molecule, Melasyl™, a light, hypoallergenic fragrance is sometimes used to mask the raw, earthy scent of these powerful ingredients and provide a pleasant application. That being said, we know that for many with sensitive skin, fragrance-free is the ultimate standard. We take your feedback very seriously and will share your comments directly with our product formulation teams. We hope to better meet your skincare needs in the future.

My new favourite product!

I’ve been using the La Roche-Posay Mela B3 Serum for just over a week now, and I’m honestly so impressed already. First of all, I absolutely love the texture — it feels lightweight, smooth, and really comfortable on the skin without being sticky at all. My skin feels amazing every time I use it, softer, healthier, and more radiant. What surprised me the most is how quickly I started noticing improvements in my dark spots. I’ve had some really stubborn marks that didn’t seem to fade with other products, but they are already looking significantly lighter after only a little over a week of use. If it keeps working like this, it’s definitely becoming a permanent part of my skincare routine.

Helps to reduce inflammation and hyperpigmentation

[This review was collected as part of a promotion.] This was the first time i used this and it helps to clear my skin i almost finished the bottle. It has niacinamide and B3 which make my skin brighter and more even. I have pigmentation on my forehead and it’s nearly gone which makes me more happy and it actually calm down my blemishes faster and keeps my skin hydrated. It removes the pimples and i have no serious break out since i am using this. The absorption is fast and my skin has improved so much. It smells absolutely fine i am very satisfied. Dark spots fade away more gradually and my skin looks brighter within four weeks.

Visible Results Over Time

[This review was collected as part of a promotion.] Really lovely serum texture and one of the few anti-pigmentation serums I genuinely enjoyed using long term. I have used La Roche-Posay Mela B3 Serum before, so I could actually see the difference after a few weeks rather than just after one use. My post-acne marks started looking lighter and my overall skin tone looked more even and brighter over time. The texture feels lightweight, hydrating and comfortable on my combination skin without feeling sticky or heavy. It layers really nicely with the rest of my skincare too. Definitely one of my favourite serums for uneven-looking skin and post-acne marks.

It’s really helping my hyperpigmentation 💙

[This review was collected as part of a promotion.] I’ve been using the new Mela B3 Serum on my face and neck for the last 3 weeks as part of my nighttime routine and so far I’m pleasantly surprised with the results. I’ve definitely noticed my dark spots appear less noticeable but the biggest plus for me is that it’s really helping strengthen my skins barrier. The serum is a lovely texture that absorbs into my skin without leaving it feeling greasy or sticky and my skin feels ultra hydrated. My son even said to me ‘Mum! I think your lotions and potions are working, you look younger!’ (that made my day!) I’m very much looking forward to seeing the results the longer I use it. Another fave from La Roche Possay.

It took about 30 minutes after applying for the smell to go away. 3 weeks isnt long enough to say if it actually works but i cant stand using it anymore. Im done and will go back to using PUR niacinamide. For reference, i have sensitive skin and this did not aggravate or irritate it. It was the smell that is going to keep me from buying/using it again.

Hi there! We appreciate you sharing your experience with Mela B3 Dark Spot Serum With Melasyl™ + Niacinamide. We understand how difficult it is to continue using a product when the scent feels too strong, especially when it lingers long after application. We’re glad to hear it did not irritate your sensitive skin, and we appreciate you taking the time to share your honest feedback with us.

Clearer Skin

[This review was collected as part of a promotion.] Having used the serum for a month now I can see visible results. I suffer from acne scars and some dark spots which has lightened/faded with a month of using this. I have oily skin and using this did not exacerbate the oiliness of my skin either. I am impressed with the lightweight, non-greasy formula. It does not pill and I can use my moisturiser on top without any transfer. It has a pleasant scent without feeling over-bearing. I like that it is suitable for sensitive skin, whilst my skin is not sensitive it is acne prone and I felt it did not irritate at all. There’s a myriad of beneficial ingredients in this and it is therefore great value as you do not need to purchase multiple products with different ingredients, they are all amalgamated into one formula. The bottle and packaging are user friendly, allowing you to dispense product easily with a pipette. Overall this is a great serum for anyone who would like clearer skin, even if not necessarily for hyperpigmentation as it helps to provide skin clarity. I will continue to incorporate this into my routine in future.

Anti pigmentation

[This review was collected as part of a promotion.] I’ve been using this mela b3 serum with the anti dark spot fluid and this combination works so well. My skin feels super hydrated after every use and I have started to notice a slight reduction to the appearance of my dark circles. The only thing is I found if I use another product like eye cream it tends to leave a white cast and forms little rubbery clumps on my face. So now I use this alone strictly which I am happy with as it works well with my skin

The best serum

I have been using this serum for a very long time and I can honestly say that it is an essential part of my daily routine. It is not sticky at all, does not leave the skin oily, and absorbs very quickly into the skin. I usually use it in the evening, as I feel the results are better. I think I'm already on my 4th or 5th bottle.. I lost count. Highly recommend especially if you struggle with pigmentation as I do

[This review was collected as part of a promotion.] I have been using this La Roce Posay Mela B3 Serum for nearly 3 weeks now, I have tested this throughly, I used this alongside the Anthelios UVMune 400 Anti Dark Spots Facial SPF50+ Fluid. For someone who has dark spots I found this serum really helped to reduce them. This serum didn’t dry out my skin, it was gentle on my skin, and I liked that it quickly absorbed into my skin without leaving any residue. Overall I was really impressed within a week with the way my skin was feeling, I would definitely repurchase and recommend.

It absorbs really quickly with no greasy feeling, which makes it perfect under moisturiser or makeup. I've tried a lot of serums but this one actually delivers. Would absolutely recommend it!

Hello! Thank you for sharing your experience with our Mela B3 Serum. We appreciate your commitment to using it both day and night, as consistency is key when targeting dark spots. While we are sorry you haven't seen a dramatic change yet, we want to reassure you that treating hyperpigmentation takes time. Because Melasyl™ and Niacinamide work to correct existing spots and prevent new ones from forming, the most significant visible improvements typically appear after 8 to 12 weeks of consistent use. We recommend continuing your twice-daily application and ensuring you pair it with a daily broad-spectrum SPF, as sun exposure can slow down the fading of dark spots. We have shared your feedback regarding the progress of your results with our Research & Development team. We hope you start to see the transformation you're looking for very soon!

Skin has never felt more refreshed!

[This review was collected as part of a promotion.] I’ve been using La Roche-Posay Mela B3 Serum together with La Roche-Posay Anthelios UVMune 400 Anti-Dark Spots Fluid SPF50+ and I’m really impressed with the results. The serum made my skin feel smoother, hydrated, and refreshed almost immediately, and after continued use my complexion looked brighter and more even. The SPF fluid is lightweight, absorbs quickly, and leaves no greasy feeling or white cast. It layered perfectly over the serum and kept my skin feeling comfortable all day. Together, both products made my skin look healthier, fresher, and more radiant. I’d definitely recommend them for anyone looking to target dark spots while keeping their skin protected and glowing.

Best thing I have tried for dark spots

Really happy with this product. It absorbs nicely with no greasy residue. Has a slight scent to it which is pleasant. I have been using this along side their 50+ anti dark spot fluid. Normally in the sun my dark spots become more prominent. But I’ve noticed that they haven’t when I have been using these products. I’ve also noticed a slight reduction and lightness in the dark spots I already have. Definitely gonna keep using this product and hopefully they will fade away completely.

✨ Brightening, Gentle & Surprisingly Elegant

I’ve been really impressed with this serum so far — the texture is lightweight, silky and layers beautifully without feeling sticky or heavy. My skin looks noticeably brighter, more even and calmer, especially around post-acne marks and dull areas. What I love most is that it feels effective without irritating my skin, which can be hard to find with pigmentation products. The combination of Melasyl™ and niacinamide gives my complexion that healthy, refined glow while still feeling gentle and comfortable for everyday use. It’s quickly becoming one of those products I genuinely look forward to using in my routine.

Dark spots and pigmentation magic serum 🎩

[This review was collected as part of a promotion.] Hey all, i was kindly sent the new Laroche-posay Mela 3 serum to test and review from Lorealistaruk & Laroche-posay. 💜 My Review : I've been using thus serum for over a week now in my morning skincare routine. I've noticed my skin tone looks cleaner and brighter. I did see some visible improvement to my skin pigmentation after 7 days of using this serum. My skin is softer and more even. I was very impressed that my skin is visibly more radiant and has a healthy glow. One of the things I love most the Mela 3 serum is it's lightweight texture. It absorbs quickly into the skin without leaving any residue, making it ideal for both morning and evening skincare routines. I was pleasantly by it's anti-aging benefits. My finelines around my mouth and forehead have appeared softer. I would highly recommend this Mela 3 Serum to my family and friends. I rate this 5 🌟.

I have quite dry skin, so I was a bit worried this serum might feel harsh, but it’s actually been really comfortable to use. The MELA B3 INTENSE ANTI-DARK SPOT SERUM feels lightweight. It gives hydrating, and it leaves my skin looking brighter and smoother without making it feel tight or irritated. After a few weeks, I noticed some of my dark spots starting to fade and my overall complexion looking more even. I also love that it layers well under a rich moisturiser without pilling.

It works! Takes a bit, but I see visible changes.

This purchase was my second bottle, the smaller size at first and now the larger one. I'm about a quarter into the second bottle and see obvious lightening of dark spots on my forehead and car-window-sun vulnerable sides of my face. Friends have noticed! It's now a part of my twice-daily skincare routine, including the corresponding SPF lotion during the day. I just wish I'd thought to take a before picture!

Exceeds expectations ... it really works. I started with the small bottle and could tell it was actually improving my dark spots, so when I came back to restock, didn't think twice about getting the large size. I've always loved being outside, lived by the ocean for a dozen years and was always at the beach. I've been faithfully applying the MelaB serum twice a day and now wear sun screen on my face every day, even in the winter, with the Toleraine Double Repair Face Moisturizer UV. I also have the MelaB3 UV and will use that too during the summer.

It has bee 4 weeks, and I see no change whatsoever. It leaves a white film after it dries, so it does nothing to soften the skin. I regret having purchased the large size.

Hello! We are sorry to hear that you haven’t seen the results you were hoping for yet. While some users notice a difference early on, deep-set age spots can be stubborn. Clinical studies for Mela B3 Serum typically show the most significant transformation after 8 to 12 weeks of consistent, twice-daily use. We encourage you to stick with it a bit longer to allow the Melasyl™ and 10% Niacinamide to work on those deeper layers of pigment. Once fully absorbed on the skin, we recommend following with Mela B3 Double Dose. An intensive treatment that reduces the appearance of age spots, sun spots and dark spots, while also targeting signs of aging. We hope you begin to see that change very soon!

Not working for me

I have been using this product for at least two months now, twice daily and following all instructions. I’m very disappointed to discover that there has been zero reduction in the 2 dark spots on my face, especially as the product has received so much hype and is not cheap.
