15% Vitamin C (Sodium Ascorbyl Phosphate) aids in preventing sun damage to the skin by destroying the free radicals that attack our skin cells when exposed to the UV rays. We suggest using this remarkable serum each morning after cleansing to arm the skin against damage. To aid in spreadability, one can add a drop of water to the serum before applying. Shake before use and apply everywhere on the face, neck chest, hands and arms to prevent sun damage. You can follow with your R three moisturizing lotion and sun block (as the serum is not a sun block).

Watch for any signs of sensitivity to the skin, especially if you're out in direct sun. If this should occur, use the serum at night after cleansing and before using your moisturizing R three lotion. With exposure to air, the residue on the inside of the cap may crystallize but this does not change its effectiveness, merely wash out the cap.
