What it’s good at
Niacinamide is a form of vitamin B3, and one of the better-studied skincare ingredients. In lab and skin studies, it helped skin make more of its own ceramides, the fats that hold water in, and dry skin lost less water. In one trial, a 2% niacinamide moisturizer lowered facial oil compared with a plain one. In another, 5% niacinamide made dark patches look lighter than the same moisturizer without it.
What it doesn’t do
It won’t make pores disappear. Nothing has been shown to change their actual size, though less oil can make them look less noticeable. It isn’t an exfoliant, so it won’t do an acid’s job, and it doesn’t protect you from the sun, so sunscreen stays. A higher percentage isn’t automatically better either. Most products sit at 5% or less, and the studies above used 2% and 5%.
Adding it this week
- After cleansing
Morning, evening or both. A few drops or a thin layer.
- Then moisturizer
Your usual one goes on top.
- Mornings: sunscreen last
Niacinamide doesn’t protect you from the sun, so this step stays.
Common questions
Can I use it with vitamin C or retinol?
Yes, for most people. It’s often paired with both, and with ceramide moisturizers too. If you’re adding more than one new product, bring them in one at a time.
Is it OK for sensitive skin?
It’s generally well tolerated. Start with a lower strength if your skin reacts easily, and patch test on your forearm for a day first.
