Advice from our team:
After cleansing and drying your face, apply a few drops of the GOODAL Black Carrot VITA-A Retinol ampoule to the entire face, avoiding the eye and mouth areas. Gently massage until fully absorbed. Use in the evening, 2 to 3 times per week at first, then increase the frequency according to your skin's tolerance. Don't forget to apply sun protection the next morning.
