Excellent for dark spots!
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!

This product works!
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!

It works after using diligently!
Not too oily, and after many applications I noticed my dark spots brightening! There was no sensitivity to the product. Give it a chance and use as directed.

“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!

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. Update its 2 months later and I have noticed the dark spots getting lighter, less noticeable, not gone, but easier to cover with concealer. It works best on the newer and lighter ones.

My favorite skin care product!!
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.

Disappointed ☹️
First bottle was working slowly on dark spot, but second one doesn’t work. No more lighting 😕. . I used it after La Roche gel cleanser clarifying micro - peeling. Non greasy and no skin irritation

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.

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.
