In just two weeks of clinical trials, 100% of participants showed a reduction in post-acne dark spots and oiliness improvement; in 4 weeks 100% said skin was clearer, and redness was reduced.

That’s super impressive. So, my sister, BFF, and I had to put it to the test.

I was very excited about the launch of Sunday Riley B3 Nice 10% Niacinamide Serum.

“For a month, I used the product as directed — applying it in the morning and at night to my face and neck. Each time, it went on smooth and silky thanks to its water base, and felt instantly hydrating — almost soothing! One month in, I notice my skin looks brighter. I also noticed my breakouts were less and faded more quickly.”

“I used it twice a day as directed, and now, one month later, I feel like it made my skin look brighter and just feel healthier as opposed to my “normal” dry, even flaky skin. I felt like I didn’t have to slather on as much moisturizer as I usually do.”


“A month in, I believe I don’t notice that much of a difference yet in the pores on my face, but the pores on the sides of my nose (which I hate!) do look smaller or shrunken. I also notice that my dark spots from sun damage have faded a bit, and I’m really happy about that.”
