Vitamin C vs Niacinamide: which serum fits your brand?
Vitamin C is the brightening story; Niacinamide is the calm, barrier-friendly story. Most new brands start with Niacinamide because it suits more skin types — then add Vitamin C as a second serum when the brand is ready.
How do they compare?
| Vitamin C Serum | Niacinamide Serum | |
|---|---|---|
| Story | Brightening, glow | Gentle brightening, pore care |
| Strength | 10% / 15% Vitamin C | Barrier-friendly, suits most skin types |
| Best first serum? | Yes, if your brand is about glow | Yes, for most new brands |
| MOQ | 1,000 units per SKU | 1,000 units per SKU |
Which one should you launch first?
Ask one question: what is the one sentence your brand says about this serum? If the sentence is about glow and brightness, choose Vitamin C Serum. If it is about gentle, everyday care that most customers can use, choose Niacinamide Serum. You can launch both — each is one SKU at MOQ 1,000 — but launch the clearer story first.
Can you combine them in one formula?
That is a custom-formula question. Tell us the story you want and the claims you sell in, and the factory team will confirm whether a combined direction fits your market's rules. Either way, you approve a sample before bulk production — see how sampling works.
