For dark circles, it is most relevant when the under-eye area looks uneven, dull, or brown-toned, and when the skin barrier needs gentle support. It is not an instant dark-circle remover, but it fits a steady 8–12 week cosmetic routine. Caption: Niacinamide can support the look of a more even tone when pigment contributes to dark circles."]},{"heading":"What It Is","paragraphs":["Niacinamide is a water-soluble vitamin B3 form used widely in leave-on skincare. In cosmetic routines, it is valued because it is generally compatible with moisturizers and barrier-support products.","For the under-eye area, the value is practical: a gentle tone-support ingredient that can sit inside a moisturizer-like eye product rather than requiring a harsh active routine."]},{"heading":"Mechanism","paragraphs":["Niacinamide is studied for improvements in the appearance of hyperpigmented spots, texture, yellowing, and blotchiness on facial skin. Around the eyes, that evidence is best translated conservatively: it may support a more even-looking tone and a smoother-looking surface over time."]}],"side_effects":[{"title":"Eye-Area Irritation","url":"https://skinknowledgebase.com/side-effects/eye-area-irritation"}]}
