Christina Aguilera Apply Christina Aguilera Red Sin Eau De Parfum right after you shower onto dry skin. The shower cleanses your body of any other scents and opens your pores, which helps the scent absorb. Completely dry your skin and then spray. Hold the spray bottle 10-15 cm from your body. Apply cologne to heated areas of your body, like your neck, chest, pulse points, forearms or inner elbows. Start with a light application and re-apply Christina Aguilera Red Sin Eau De Parfum if needed. Auto Scents
