Core Brightening Sheet Mask with Niacinamide

A brightening sheet mask formulated with 5% niacinamide, tranexamic acid, and arbutin to target uneven tone and dullness. It’s rare to find a sheet mask with such a high concentration of niacinamide, making this more of a targeted treatment than just a hydrating step. The addition of rice and sea buckthorn extracts gives it a nice boost for tired skin, though the active-heavy formula means it's best used when you're specifically looking to tackle stubborn spots or post-breakout marks.
