Niacinamide (Vitamin B3)
Niacinamide is a versatile, well-tolerated vitamin B3 active that helps with uneven tone, visible pores, oil control and barrier support. It is one of the safest, most useful ingredients in skincare, which is why Medicube works it into so many of its formulas.
How niacinamide works
Niacinamide is a genuine multitasker. It supports the skin barrier, helps regulate oil, reduces the look of pores over time, and gradually evens out tone and post-blemish marks. Because it does several jobs gently, it suits people who want visible improvements without the irritation risk of stronger actives.
Why it is so widely used
The big appeal is tolerance. Niacinamide layers with almost everything, works morning and night, and rarely upsets even sensitive skin, so brands can include it across a range without compatibility worries. In Medicube's line-up it often sits alongside PDRN and peptides to round out the "glow and even tone" story.
Who it suits
Almost everyone. It is especially useful for oily, combination and blemish-prone skin thanks to the oil-and-pore benefits, and gentle enough for sensitive skin. If you want one low-risk active to add to your routine, niacinamide is a strong first choice.
