Just after the application of a moisturizer, apply Radiance in a Flash all over face and neck, with a touch of powder to shine in a flash, in the morning or the evening. To maximize the lifting effect, apply the care from the bottom to the top of the face: from chin to cheekbones, eyebrows to the hairline.
