What the gurus are saying
This niacinamide serum impresses for doing double duty: it hydrates while keeping oiliness in check, a balance that matters for people managing both concerns at once. The 10% niacinamide pairs with arbutin to tackle dark spots and uneven skin tone, making it a solid pick if discoloration is something you're working on. A couple of gurus have weighed in so far, both giving it warm marks, but there isn't a large body of takes just yet.
