Excellent
Here’s a clear and honest Amazon-style review based on the product in your image: ⸻ I’ve been using the La Roche-Posay Mela B3 Serum for a few weeks now, and overall I’m quite satisfied with the results. The texture is lightweight and absorbs quickly into the skin without feeling greasy or sticky, which makes it easy to layer with other products. One of the things I appreciate most is that it feels gentle on the skin. I didn’t experience any irritation or breakouts while using it, even on more sensitive areas. Over time, I’ve noticed a slight improvement in the appearance of dark spots and overall skin tone—it looks a bit more even and brighter. That said, the results are not instant. It takes consistency and patience to see visible changes, so if you’re expecting quick results, this might feel a bit slow. Also, the dropper works fine, but sometimes it doesn’t pick up a full amount of product. Overall, it’s a solid serum for anyone looking to gradually improve skin clarity and tone with a gentle formula. I would recommend it, especially if you prefer lightweight skincare that doesn’t feel heavy on the skin.

“Spectacular results” Love it ❤️❤️
I have to share this with you!!!!!. This is my 5th bottle, and I can honestly say I’m beyond impressed with the results. At first, I had my doubts, but this product has truly exceeded my expectations. I’ve seen amazing improvements, especially on my décolletage area, which used to be one of my biggest insecurities. The appearance of dark spots and uneven tone has consistently improved over time, and my skin now looks much more even and radiant. I use it every night before going to bed, and on alternating days I also apply it in the morning, always followed by sunscreen. This routine has made a huge difference. The texture is silky and not sticky at all, and it has a very delicate, pleasant scent, which makes it even more enjoyable to use. If you’re dealing with sun spots or discoloration like I was, this product is definitely worth trying. I’m extremely happy with the results and will absolutely keep repurchasing!

My second bottle! Repurchased because it actually works on acne scars
This is my second time purchasing this serum, and I absolutely love it! I used to use the previous La Roche-Posay formula, but this new Mela B3 version is fantastic. It has noticeably improved the appearance of my skin and has done wonders for my past acne scars and dark spots. It’s gentle, absorbs beautifully, and delivers real results. If you are struggling with post-acne marks, this is worth every penny. Highly recommend

Lighten dark spots
Dermatoligist recommend, so I've been using for a few weeks two times a day. I haven't really noticed much, maybe a little lighter dark spots, that's why only 4 stars. It doesn't irritate my skin, not itchy or sticky. Just a few drops and it absorbs quickly. It does not protect against the sun or moisturize so after applying Mela B3 to clean skin you will need to apply moisturizer and sun screen, just as well because I like my brand now. I will continue to use it to 1-see if dark spots will lighten as promised and 2-to keep new ones from appearing.

Easy for use
Gentle and lightweight serum that helps brighten skin and fade dark spots over time. Great for sensitive skin and daily use, but results are gradual.

Super good for dark spots
I’ve been using this serum for several days now, and I really like it. It has a lightweight texture that absorbs quickly and doesn’t leave my skin feeling sticky, which is very important to me. I bought it mainly to help with dark spots, and little by little I’ve noticed my skin looks more even and smoother. It’s not an overnight miracle, but you can definitely see improvement with consistent use.

Great serum, but pricey and runs out quickly
This item is great, but it is definitely pricey, and you go through the bottle pretty quickly. At first glance, the bottle looks like it contains a good amount, but it’s important to realize that it is only about 70% full and not filled to the top. That said, the consistency is really nice. It has a pink serum-like texture, and after using it for two months, I’ve noticed that it has helped my skin look more glowy and healthy. I would recommend it, but just keep in mind that it is expensive.

OK.
Bon produit, agréable na pique pas ma peau sensible mais efficacité il faut voir dans la durée, trop court pour juger les résultats. Un petit bémol: le carton d'emballage est arrivé éclaté. C'était pour moi donc pas grave mais si vous achetiez pour offrir ça peut poser des problèmes.
