The best approach to dark spots pairs a brightening serum — vitamin C, alpha arbutin, tranexamic acid, or niacinamide — with daily broad-spectrum sunscreen; without SPF, sun exposure keeps re-triggering the pigment faster than any serum can fade it.
Dark spots — from sun, acne marks, or melasma — are the slowest skin concern to fix, and the one where sunscreen matters most. Brightening serums gradually fade existing pigment, but daily SPF is what stops new spots from forming. These serums target pigment through different pathways; many people combine two, plus sunscreen.

The Ordinary Alpha Arbutin 2% + HA
There’s no overnight fix, but the fastest realistic route is a brightening serum (vitamin C, alpha arbutin, or tranexamic acid) used consistently plus daily broad-spectrum sunscreen. Most people see gradual fading over 8–12 weeks; a dermatologist can offer stronger options for stubborn pigment.
Usually because of sun exposure. UV light re-triggers pigment production, so skipping sunscreen lets new spots form as fast as serums fade old ones. Daily SPF is the single most important step for keeping spots from returning.
Yes. Niacinamide helps interrupt the transfer of pigment to skin cells and evens tone over time. It’s gentle enough to combine with stronger brighteners like vitamin C or alpha arbutin for a layered approach.
