Sunday Riley B3 Nice 10% Niacinamide Serum

I've been using this serum for a week and my pores look smaller and my skin looks more radiant. It feels light on the skin and absorbs quickly. The dropper is easy to use. I'm so happy I bought this on sale!

This serum has faded my dark spots significantly. I use it twice a day and my skin tone is much more even. The only reason I'm not giving 5 stars is that it can pill if I don't wait for it to dry completely. But it's a good product.

I like how this serum makes my skin feel smooth and how it minimizes my pores. However, it leaves a slightly tacky residue for a few minutes. I usually put a moisturizer on top to seal it in. Overall, a good value.

I have oily, acne-prone skin and this serum is amazing. It controls my oil production and doesn't break me out. My skin looks clearer and healthier. I've already recommended it to all my friends.

I used the whole bottle as directed, but I didn't see any dramatic difference in my pores or skin texture. It didn't break me out, which is good, but it just didn't do much for me. Maybe my skin is used to niacinamide.

This serum is fantastic! My skin feels smoother and looks brighter. I love the ingredients and the fact that it's alcohol-free. A tiny amount goes a long way, so the bottle lasts a long time. Absolutely recommend.

This serum is very watery and thin, so it's easy to apply. It absorbs well and doesn't leave any film. I just prefer serums with a thicker, more luxurious feel. Still, it's effective and I'll continue using it.

I'm 62, and this serum has been a wonderful addition to my routine. It plumps my skin and reduces the look of age spots. My skin feels more supple and I've gotten compliments. It's very gentle on my sensitive skin, too.

After a few days of using this, I started getting small bumps on my forehead. I'm not sure if it's the serum, but I stopped using it and the bumps went away. I'm disappointed because I wanted to like it.

I got this at 50% off, so it's a steal. It's a nice serum that does what it claims – my pores are less visible and my skin looks more radiant. I'd repurchase at the sale price, but not at full price.
