Most products use green-tinted or color-transforming pigments to neutralize redness—examples include green-to-beige color-adapting pigments and encapsulated or color-transforming beads that adjust to match skin tone.
Beyond neutralizing redness, listings commonly cite hydration and moisturizing, soothing and calming irritation, restoring the skin barrier, brightening and evening skin tone, minimizing the appearance of pores, improving texture, anti-aging or elasticity benefits, and extended makeup wear.
