Great product so far

I haven't been using this product long-but it's already making a difference in my skin. I'm trying to get rid of dark spots and they have already lightened a bit and the surrounding skin looks great too !

Wanted to like

The serum caused my sensitive skin to break out. Sadly I had to discontinue using.

Dark Spot fading

I’ve got a couple of dark spots on my face that I’ve used this on. I’m very pleased with the results. It didn’t break out my skin or leave it dry. The spots started fading quickly!

LaRoche -Posay Melba B3 Dark Spot Serum

I bought this for my husband to use for the dark facial spots on his forehead. This is the second bottle that he is using. So far the spots are getting somewhat lighter but still visible. Hoping that with continued use with the product and using sunscreen along with wearing a hat to protect from the UVA rays will achieve the desired results.

Love this!

I really like this Mela B3 Dark Spot Serum. It smells great, feels great on the skin and easy to apply. Still too early to tell whether the dark spots are reduced but will keep using it to give it a chance.

I’m liking it!

I’ve been using it for about a month and I like the way my skin is responding. It seems clearer and healthier. My dark spots aren’t getting worse so that’s a good sign that it’s working. I’ll look forward to seeing what it does in the future, as it can take some time to see the whole effect.

La Roche-Posay Mela B3 Dark Spot Serum

I was first introduced to this in a sample. I really liked it and ordered a regular size tube I am pleased with the results,. Using this every day has yielded results. It does not dry the skin and gradually I have noticed a decrease in dark spots and lightening. Will reorder

Best Dark Spot Corrector

I’ve tried so many different serums over the years to lighten the persistent dark spots on my face. None worked until I found La Roche-Posay’s dark spot corrector. I believe that it’s the 10% niacinamide in the formula that makes it so effective. Most brands that I have used contain only 5%. I highly recommend this product.

Yes!

I have very sensitive skin with rosacea and I did not have any problem tolerating this serum. I have seen improvement in melasma ( bit lighter) I have been using for about 1 month, this will be a repurchase for me.

Jury still out

I've been using this product 2x a day since March 2025. My dark spots are no worse but I can't say they're significantly improved or gone. I see some fading but not to the extent I expected based on some reviews and previous experience with LR-P products.
