Thank you for your kind words! Your kitty appears to have feline acne. Sometimes the cause is plastic allergy (not in your case) and sometimes it's an allergy to something else and that something else is very difficult to figure out. In addition, the chin is one of the areas some cats do not clean as well. Use a warm wet soft cloth and scrub the chin vigorously every day, even if it bleeds a bit. Continue this for several days and see if there is improvement. If it doesn't improve or gets worse, see your vet.
