Can I use the ARTISTRY® Renewing Reactivation Day Cream or Day Lotion SPF15 day and night?

No.  As the Renewing Reactivation Day Cream & Day Lotion SPF15 contain a sunscreen, you would only use your chosen Cream or Lotion SPF15 during the day.  Beyond SPF, both the Cream & Lotion SPF15 formulas include Carnosine, a clinically proven ingredient known to help prevent visible damage from blue light and infrared light. Like UV rays, blue light and infrared can damage skin and create an unhealthier appearance.
