The actives.
Vitamin C
L-Ascorbic Acid
The gold standard of brightening. L-Ascorbic Acid is the only form of Vitamin C with proven penetration into the skin's deeper layers. It inhibits melanin production, stimulates collagen synthesis, and neutralises free radicals from UV exposure.
Most products use 5–8% — effective for maintenance. At 15%, you're targeting existing hyperpigmentation. That's the difference between preventing and correcting.
Niacinamide
Vitamin B3
Niacinamide is one of the most studied ingredients in skincare. At 10%, it visibly minimises pores, regulates sebum production, strengthens the skin barrier, and fades dark spots — all simultaneously.
We pair it with Zinc PCA, which addresses sebum oxidation at the source. Together they do what neither achieves alone.

SPF 50 · PA++++
UV exposure is the single biggest driver of hyperpigmentation, premature ageing, and skin damage. No brightening serum works properly without daily sun protection — they're working against each other otherwise.
Zero-Cast uses a combination of chemical and physical filters selected specifically to avoid the white cast that makes most high-SPF products unwearable on South Asian skin tones.
