Every few months a new "holy grail" ingredient shows up on Instagram, and right now it's a toss-up between Vitamin C and Niacinamide. Ask five skincare pages which one you actually need and you'll get five different answers. Here's the honest one: you don't have to choose, and for most people, using both (just not at the exact same moment) is what actually moves the needle on dullness and uneven tone.
What each one is actually doing
Vitamin C, in the form we use in our 10% Brightening Serum, is an antioxidant first. It mops up the oxidative stress your skin picks up from sun, pollution, and just being alive in a city like Delhi or Mumbai, and along the way it interferes with the process that leads to excess pigment. That's why it's the ingredient most associated with a visible "glow" — it's not adding shine, it's reducing the dullness that was hiding it.
Niacinamide works differently. It's less about brightening in the moment and more about long-term skin behaviour: oil regulation, a stronger moisture barrier, and a slow fade of the marks left behind by old breakouts. If Vitamin C is the ingredient for how your skin looks today, Niacinamide is the one working on how it behaves over the next few months.
Why people mix them up (and why that's fine)
There used to be a rumour that combining Vitamin C and Niacinamide cancels both out. Most current formulations, including ours, are stabilised specifically so this isn't an issue. Where people do run into trouble is applying too much, too fast — stacking a Vitamin C serum, a Niacinamide serum, an exfoliating acid, and a retinol all in one week. Skin doesn't reward enthusiasm, it rewards consistency.
A routine that doesn't overcomplicate things
If you're starting fresh: Vitamin C in the morning, under sunscreen (it genuinely does very little without SPF backing it up), and Niacinamide at night after cleansing. If your skin is more on the reactive side, alternate them night by night instead of using both daily. Give it four to six weeks before deciding if it's working — skin cycles are slow, no matter what the packaging promises.
The goal isn't to collect every trending ingredient. It's picking two or three that actually address what your skin is doing right now, and giving them enough time to work.
