Adopt this firming serum as your new "prejuvenation" step. After cleansing and toning, apply 2 to 3 pumps to the face and neck, avoiding the immediate eye area. Use it preferably in the evening (also in the morning if your skin tolerates it), then follow with a moisturizer. As with retinol, remember to apply sunscreen during the day to enhance the anti-aging effect while protecting your skin.
