For optimal results, use the Power C 20% L-Ascorbic Acid Cream as part of your morning skincare routine. After cleansing and toning, apply a small amount of the cream to your face and neck, avoiding the delicate eye area. Follow up with a moisturizer and sunscreen to protect your skin throughout the day. Due to its high potency, we recommend using the Power C cream no more than once daily and gradually increasing frequency if tolerated well by your skin.
