This La Roche-Posay serum truly delivers on its promises. I have been using it to even out my skin tone and fade acne marks, and the results are visible within just a few weeks. It has a lightweight texture that absorbs instantly without leaving a greasy feeling, and since it contains niacinamide, it is extremely gentle and causes no irritation at all. Although it is a high-end product with a premium price tag, it is totally worth it for its effectiveness and performance. Highly recommended!

I have been using this for over 2 years now. It’s not some magic wand that clears spots, but I have seen improvements. It has worked over time to correct some dark spots and tone issues. The serum is lightweight. A bottle lasts me a month+. It would be great if it comes with tamper proof. It’s either that or I stop buying it from Amazon. The last order had some liquid on the body which makes me worry about the content.

This product is very good for dark spots. I had a dark spot on my forehead so I started using it to help me getting rid of it and it definitely worked. I use sunscreen all the time after applying it to the area and even in the house to prevent skin damage. If you guys are looking for a good product for dark spots removal please don’t hesitate to try this. I’ll definitely order one more soon🫶

Como pueden ver, he comprado 2 productos, uno el bote es morado Mela B3, y el bote naranja Retinol B3, uno por la mañana y otro por la noche, con estos dos, ya no aplico nada más, porque siento que hay humedad suficiente, y sí, he notado mucha mejoría, me ha reducido las arrugas finas y la cara está más tersa. El Mela B3 lo compré cuando estaba con 40% de descuento, lo cual me alegra un montón, porque ahora ha subido mucho. Eso sí, el bote morado Mela B3, me vino roto la boquilla, se ve que ahí ha fallado el control de calidad.

I really love this serum! I’ve been using it for a while and I can see my skin looking more even and brighter. It feels lightweight, absorbs quickly, and doesn’t irritate my skin.

I've had a dark brown spot on my forehead and within 1-2 months of applying this it has substantially faded! I'm so happy. I will try to find before and after photo to attach. I haven't been 100% consistent with putting it on morning and night but I've been pretty good about at least once a day. Definitely worth the purchase.

tengo piel mixta, pecas pequeñas del sol. Lo usé más de dos meses de forma constante de dic y noche, con mi protector solas siempre y la experiencia ha sido ok A favor: textura muy ligera, se absorbe rápido y sin irritación — nada fácil con niacinamida al 10%. Se incorpora bien en cualquier rutina. En contra: mis pecas solares no mejoraron visiblemente. Puede funcionar mejor en manchas post-acné o manchas más recientes, pero en mis pecas no noté diferencia real. No es mal producto — la fórmula es seria y la marca confiable — pero para mis manchas específicas no fue suficiente. Recomiendo combinarlo con protector solar diario y tener paciencia, aunque en mi caso mas de dos meses no fueron suficientes para ver cambios.

Haven’t used this for very long but I can tell that my hyperpigmentation is getting lighter which is good, as I know it won’t completely go away but if it lightens it up, I’m good with that

This serum is amazing! I noticed visible decrease in my dark spots after a month of use. The key is to maintain consistency - ensure that you incorporate into your daily routine and stick with it! It does not have a bad odor like some of the other products I’ve tried. It takes a little time to dry but does not leave your face feeling greasy. In my opinion this is a fabulous option for those looking to fade their dark spots!

I am addicted to this! I use it twice a day and have had multiple people say my skin looks great since starting this. It is brightening and incredibly moisturizing. It feels luxe putting on. I love the slip. I wish it weren’t so expensive, and I wish the dropper were better. But I’ll keep buying it. My favorite skin care product.

I'm 60 and I don't usually write reviews, but i had to for this product. I saw results the first week. I cleanse my face with La Roche-Posay Mela B3 Gel Cleanser, apply the serum alone twice a day. When I'm going out I use the La Roche-Posay Mela B3 UV Daily Sunscreen, Face Moisturizer With SPF 30 + Anti-Aging Melasyl + 5% Niacinamide. I'm currently on my second bottle and I will be purchasing again.
