Seems to be fading my dark spots.

Received some samples of this product. Enough for two weeks. Was impressed with the slight fading of these dark spots in just two weeks. I bought the full size bottle. Will see how much fading will be achieved when the bottle is finished. If it continues to do it's job I will write a review and give it 5 stars.

Not as good as Niacinamide 10

Mela B3 was recommended after La Roche-Posay stopped making their Niacinamide 10 Serum. Mela B3 is a decent substitute, but I really miss the Niacinamide! The Mela B3 does have a nice slip to it when you put it on, and seems to brighten my skin. I'll keep using it, but I wish they still made the other! :(

LaRoche Posay Dark Spot Serum

Pleasant scent and hydrating. I haven’t been using it long enough to see results but skin is smoother.

Slight difference

I can see a slight improvement though I haven't used it up to 3 weeks. I am optimistic it will give me a good result

Decent product

This product applies smoothly and has a nice scent. However, I have only seen a minimal reduction in dark spot coloration on the worst spots. Lighter spots reduced more. Once I finish the bottle I will probably try a different product.

I used Mela B on my dark spots and after 2 weeks I noticed a slight improvement and I will continue to use Mela B along with vit C and hope for further improvement

Dark spot serum

This product worked well to lighten the dark spots on my face, but some areas lightened more than others. I didn’t notice any offensive odor and it did not cause any irritation. I will continue to use this product in hopes of achieving more results.

Good Product

I’ve been using for about one month now and have seen a slight improvement to a couple of dark spots on my hands and face. So far so good and at a great price point.

Item to review La Roche-Posay Mela B3 Dark Spot Serum

I have 1 small dark spot that doesnt seem to budge! I have tried many products, but with this one-I think it's getting a little lighter. 5 stars for the product that makes it disappear!!!

Faded life-long freckles and dark spots on face and back of hands

I received a sample of this product with one of my orders and noticed fading discoloration within a few days of starting to use it. That was good enough to encourage me to order a full bottle. It's been a month or so and I expect that I won't get much more improvement, but have been pleasantly surprised at the results, and lack of irritation to my sensitive skin.

Time will tell!

I’ve been trying to fade a sun spot on my chest for the last year or so. I’ve tried all kinds of serums and even Rx retinol. It has been getting a little lighter but then I got a deluxe Mela B3 sample, which lasted a few weeks. I think it’s been getting lighter, more quickly. Ordered the full size hoping it will do the trick by summer. Can’t hurt!

pretty good

I am in my mid 50s with olive skin and have used this for 2 months daily so far. I tend to hyperpigment and get sun spots easy and this seems to be working ok as I have seen slight fading. I use it in conjunction with their Glycolic B5 dark spot corrector serum in the evening and I think this combo is the way to go if your skin is too sensitive to use retinol products.

impressed with sample

I got this as a sample and decided to try it on my hands. very light skin with lots of brown spots (70yrs old) I had enough for about 4 days but it really did seem to lighten the spots a bit. After using the sample I purchased a bottle and am very impressed. The spots on my hands are definitely fading.

So far so good

I don’t think I’ve been using this long enough to see results yet, but so far I do love the consistency of this product and it doesn’t break me out. I have had good luck with other LaRoche Posay products, so I am hopeful this will fade some spots.

Seems to be helping

It took many years to get these dark spots, I expect it will take awhile to see huge improvement. So far it seems to be helping. I will continue to use.

Mild scent, very gentle

I like this new improved version. The scent is not as strong. I use, along with other products, to keep melasma at bay.

Great Product!

This has become another staple in my morning and evening skin care routine. It is a reasonably priced way to add Niacinamide to skin.
