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

Love La Roche posay
I love this serum. Expensive do I only buy when on offer. Unsure if corrects hyperpigmentation completely. But my skin feels and looks lush when using

Didn't make any difference
Didn't make any difference. Used it for 4 weeks and no difference. Dark spots have not gotten any lighter

Very expensive for not having protective plastic on the packaging
The product was open without the protective plastic; honestly, for something so expensive, I didn't expect this kind of service from La Roche-Posay.

My honest review of Mela B3 Serum
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.

Orijinal
Bence orijinal amazon gönderici satıcılı dan alın kokusu güzel rengi açık şeftalı pembe arası, ben cildiye doktorumun tedavi planı için aldım içindeki melasyl in alternatifi muadili ürün yok maalesef diğer bileşen zaten niacinamide henüz üç haftadır kullanıyorum net bi etki görmedim tüm yaz devam
