Mela B3 Dark Spot Corrector Serum.

"I am also a big fan of the La Roche-Posay Mela B3 serum, which has 10% niacinamide. That texture is a little bit richer. It almost feels like a lightweight lotion rather than a true serum. So, I like it for more mature or dry skin. And because it not only contains niacinamide, but also mel, which is a patented pigment fighting ingredient from L'Oreal, it's particularly good if people are trying to fight pigmentation by incorporating niacinamide in a higher concentration within their routine."

"I've used La Roche-Posay Mela B3 serum quite a bit in the last couple years since it came out and I have to say that's also unfortunately pretty mid. I do love the brand. They make great skin care, but I haven't been impressed. My patients haven't been impressed by their melisel ingredient that was supposed to even compete with hydroquinone, prescription hydroquinone. And I'd say I've been a little disappointed by it."

"This is probably by far my favorite one in the category. I've used this since they switched in and added the melisil and I've really liked it. It really targets the dark spots, the melasma, the post acne marks, but it was still gentle enough for my rosacea skin. The niacinamide in here is going to help strengthen the barrier and calm the irritation which is going to make it suitable for daily use even for somebody with rosacea like me. What's really cool about it is that it has this patented melisil technology that's going to help prevent new pigment from forming. So you're combining the melisil with the niacinamide. It's really like a perfect match made in heaven. If you suffer from sensitive, acne prone, and pigment skin, this one's really a good one to try. It's suitable for daily use even on sensitive skin, and it's going to go really well underneath the sunscreen. The serums are a little bit thicker, but they layer really nicely even underneath the lightest sunscreen. The key ingredients here are niacinamide 10%, the melonic acid, and of course the La Roche-Posay Thermal Spring Water."

"In the La Roche-Posay line they have their Mela B3 serum. It has the proprietary La Roche-Posay spring water in it so I love it, it's soothing and this ingredient has so much research behind it, like multiple years of research, and it's not harsh on the skin either. So I do like that for people who may have sensitive skin and they're looking for something to still help lighten dark spots on their face."

"I think there's better out there for brightening. If you are at a wit's end and you have really bad melasma and you're trying to add every possible product on the market and you're not reactive to niacinamide, adding this with a complete serum or something that is a little bit more potent is a great add-on. But for me, I'm under control, so I don't think I'll be using it in my routine."

"They essentially have this Mela B3 serum and it's kind of like this light purple color and it's a vitamin B serum that is niacinamide and it's not very special it has fragrance it's gone viral on the internet but it's like 44 to 50 bucks. And they also test on animals which is why I don't use them. If you buy it here it's like 40, 50, 60 bucks like what the La Roche-Posay can be a no no."
