Niacinamide 101: What Vitamin B3 Does in Skincare (and Who Should Use It)

Niacinamide 101: What Vitamin B3 Does in Skincare (and Who Should Use It)

Niacinamide (vitamin B3) is one of those "quiet achiever" skincare ingredients: it's widely used because it can pair well with many routines and skin types. SilisbySilis positions its Vitamin B Serum as a lightweight daily serum that contains niacinamide (Vitamin B3 – 5%) and panthenol (Pro‑vitamin B5 – 2%). The product page also frames it as suitable for acne-prone skin, with benefits around regulating sebum and minimizing pores.

So what does that mean in real life?

  • If you're a teen: niacinamide is often chosen for routines where you want a light feel and less "sting." Acne is common in teens, and consistency matters more than aggressive swapping.
  • If you're in your 20s–30s: it's a strong "base serum" to support a balanced routine—especially if your skin is both oily and easily dehydrated.
  • If you're 40s+: it can be part of a barrier-first routine alongside hydration and sunscreen.

How to use it (simple): apply a few drops morning and night before oils/moisturizers, as directed on the product page.
