The real deal affordable dark spot treatment
If you prioritize something with a cute package and irresistible scent this is not your serum. However if you struggle with dark spots on your skin/melasma this serum is definitely a helper with guaranteed improvements. It’s not a miracle maker but since I started using it 2x day some of my dark spots lit up or reduced size. More importantly - had no other dark spots appearing on my face since!!! It smells and has the texture of a treatment product- it’s not fragrant at all and if applied in excess will create a yellowish paste on the skin. However if well applied and spread on the skin before your moisturizer none of this will happen. I was quite faithful to caudalie’s vinoperfect serum (has an equivalent cost) but this one, in results definitely makes la roche posay in the lead of anti-pigmentation skincare.

Great quality and gives you great results
The product lasted me over two months using it twice a day. It did improve the texture of my skin making it look a lot softer! I think it contributed to reducing my pores. It didn't help that much to remove small areas of melasma, but I guess I will need a stronger product for it. I would say it is worth to buy but I also think there's other brands out there you can get for less and gives you the same result. If I can get it with discount I will get if again for sure!!

Good
I had some scars on my face. It did work after few uses. I only used one bottle. Then I used something else to get rid of my scars. But this works

Divine smell.
Bought at a great price, and the product most importantly - is authentic. This is the only dark spot serum that works for me. And if you’re looking for a serum that not only the consistency is smooth but smells divine I would highly recommend. The serum melts into your skin seamlessly without any sticky residue and I’ve seen significant results using this serum after sun exposure from the summer months.

Great results after a year!
I’ve been using this serum for about a year now, ever since it first launched, alongside my Korean skincare routine. The difference has been really noticeable. It’s not a miracle cure, but you will definitely see results, most of the hyperpigmentation on my face has lightened. Picture below is before and after (in combo with other products)

Bad product
Terrible product! I bought this serum expecting good results, but instead, it caused a horrible breakout all over my face. My skin was completely fine before using it, and after just a few applications, I ended up with painful acne. To make things worse, Amazon refuses to accept a return even though the product clearly caused a reaction. If you have sensitive or acne-prone skin, STAY AWAY from this

Requires more time for evaluation.
Easy to use - but so far no apparent difference visible regarding hyperpigmentation. See review of La Roche-Posay cleanser already submitted.

Excelente producto, elimina las manchas, tanto las de "paño o melasma" como las de acné. Si la la mancha es pequeña en una semana desaparece, el paño lo aclara considerablemente con el uso constante, además de usar protector solar. Vale mucho la pena le producto. No me irritó la piel en ningún momento, su consistencia es ligera y con una o dos gotas es suficiente por aplicación, aunque depende de la extensión de la mancha.

It is so far the best anti-pigmentation serum. It obviously doesn't work in years old stubborn pigments that need laser but on fresh ones it does a great job. I had breakouts on my arms that left tiny brownish spots behind, these look much better with most of them gone.

Effective product for dealing with hyperpigmentation. Remember to use your sunscreen to prevent further skin damage

I’ve always been quite skeptical about cosmetic products — they often seem to promise more than they actually deliver. However, my experience with the Mela B3 Serum has been surprisingly positive. I’ve had melasma since the birth of my daughter, more than ten years ago, so I don’t expect it to disappear overnight with just one product. After about 30 days of consistent use, I noticed — and confirmed through photos — that the darker spots became slightly lighter, and some of the lighter ones have partially faded. I use the serum twice a day (morning and night), after cleansing my face with La Roche-Posay Purifying Wash, followed by sunscreen, which I reapply throughout the day. I plan to keep using it and hope to see even better results over time. I believe this is the kind of product that shows its best effects with long-term use and careful sun protection. It’s also worth mentioning that I have rosacea, which had recently flared up quite badly. Since starting Mela B3 Serum, my rosacea has improved significantly — I’d say by around 70%. The redness, affected area, discomfort, and itching have all decreased noticeably. Overall, I’ve seen a remarkable improvement in my rosacea.

Empecé a usar este sérum para tratar manchas y unificar un poco el tono, sabiendo que este tipo de productos no hacen milagros rápidos. Lo he aplicado de forma constante, sobre todo por la noche y siempre acompañado de protector solar durante el día. La textura es ligera, se absorbe rápido y no deja sensación pegajosa, algo que para mí es importante porque no me gusta sentir la piel cargada. No me ha provocado irritaciones ni reacciones, y eso que tengo la piel algo sensible. En cuanto a resultados, no se notan cambios de un día para otro, pero con el uso continuado sí he visto la piel más uniforme y con mejor aspecto general. Las manchas no desaparecen por completo, pero se ven algo más atenuadas con el tiempo. Como punto a tener en cuenta, el precio es alto para el tamaño del envase y hay que ser constante y paciente para apreciar resultados. Si alguien busca un efecto inmediato, probablemente se lleve una decepción. En conjunto, me parece un buen sérum para quien busca mejorar el tono de forma progresiva y sin irritar la piel, siempre con expectativas realistas.
