Vita B3 Source, 1.35 fl oz (40 ml)

I love using this serum in the mornings to reduce the size of my pores and control sebum. The serum consistency is runny, kinda thick and not sticky. It takes a second for it to absorb. I spent over a year trying different vitamin c serums, and just felt that I was still getting skin sensitivity, breakouts, and broke skin barrier. I remember my skin loved 10% niacinamide and I saw so many positive reviews of this serum. After using this serum for a month, I see why people continue repurchasing this bottle. I will be one of those people. There’s no irritation, the tiny bumps around my jawline is gone. I love the glow that I get from the brightening ingredients of niacinamide and arbutin. This is a holy grail for me!

This serum is gentle enough for sensitive skin, which is a big plus! It leaves my skin feeling silky smooth after each use. Overall, very pleased with it.

I’ve been using TIAM Niacinamide for a while now and I genuinely love it. It’s lightweight, absorbs quickly, and doesn’t feel sticky on the skin. I noticed my skin looks brighter and more even, and my pores appear less noticeable with consistent use. It layers well with other products and hasn’t caused any irritation, which is a big plus for me. Simple, effective, and definitely worth trying if you’re working on skin tone and texture. There’s no specific scent, which makes it all the way better. Great quality too.

The size and packaging are ok. Gentle and great for sensitive. It leaves your skin spotless and flawless.

I really like the light texture of this and the combination of ingredients, and the 40ml size. I like to use it on the days I do a chemical peel, it has been a gentle serum for layering for me.
