Not really sure what you mean but if you're talking about the "white line" then I used to have that but ever since I've used GIAB I don't really get it anymore.
Does it make your lips look kinda chapped? If yes, then that's a good thing and the product is working. Another thing, did you keep the buildup (dead skin) on before applying GIAB because you should apply it only when the lips are raw. Also, there's no need to reapply every day. You apply it once on raw lips then you leave it alone until comes off on its own which should take a few weeks maybe. At the beginning I used to apply every 30 minutes just to make sure my lips were covered but later realized it was totally unnecessary.
