Hi and thank you for sharing your concern here! Yes, you need to continue using the post-treatment creams until you run out of them. I also always recommend my patients to apply their own sun block, after they ran out of the sun block that came with VI peel. VI peel is a very good medical-level peel and helps to give a nice glow to skin as well as fading the pigmentations and helping to reduce fine lines. Hope it helps and good luck!
