Directions: Open the AHA ampoule by pushing down on the cap. Open the collagen bottle by pulling the arrow away from you. Add the aha liquid to the collagen bottle. Place the nozzle on the vial and shake until the collagen tablet has dissolved. Pour a small amount into the palm of your hand & apply the product with your fingertips on a clean, dry skin. Apply up to 3 coats, allow to dry & allow to act as a night treatment. If the skin feels overstimulated after 60min, wash off & apply night cream. Apply every night or every other night depending on the skin’s tolerance. If the skin becomes hypersensitive, reduce the use to every four nights. Avoid sensitive areas such as the upper eyelids & lips. The second bottle can be started immediately after when the first bottle is finished (about 7-10days after) if the skin tolerates it. All skin types – Except sensitive skin. 2 ampoules x 2 collagen vials.
