It does help but be careful wich tooth paste you use (don't use whitening toothpaste) I found that if u mix the toothpaste with some water 💦 then it won't burn if it usally does and it is being kinder to your skin, also if u have excma don't rub it in as it will irritate the skin even more, as son as the watered toothpaste dries take it off to check that it hasn't irritated your skin even more if it is your first time (or if you have extremely irritating skin)
