Science & Benefits

CI 45410 is a synthetic colorant often used in products that claim to 'adjust' to your personal skin chemistry. While it has a lower comedogenic rating (2) than its sibling Red 36, it poses a secondary risk: it is almost exclusively formulated alongside heavy waxes and oils to ensure even distribution. These 'carrier' ingredients often amplify the dye's ability to settle into the pores. For most users, it is a moderate risk, but when found in heavy cream blushes, the cumulative effect can lead to 'cheekbone congestion'—a common pattern of tiny, skin-colored bumps along the upper face.
