Yes, very easy to apply to the lips. The version of Bepanthen that I bought doesn't state that it is for nappy diaper rash like some other ones do. I dab some of it on and it turns clear on my lips within seconds. Yes, it penetrates extremely well. It saturates the buildup (whatever little I have of it) on my lips and really makes my lips feel moisturized. However, I am getting a very, very minor tingling burning sensation from it now but, not enough to really worry.
Oil pulling is an ancient Ayurveda medicine treatment that involves taking a tablespoon of either sunflower, sesame or coconut oil and swishing it in your mouth for about 20 minutes before spitting it out. You NEVER swallow the oil. I actually swallowed like a drop of it in my mouth by accident and I got an instant sore throat.
The chemical properties of the oil attracts (AKA pulls) all types of bacteria to it. I then brush my teeth right after oil pulling to remove any left over germs/bacteria. This has helped me tremendously, not just with my EC but also with the overall health of my mouth.
There is all sorts of information on oil pulling on-line. There really truly is no wrong way of doing it, except not to do it at all.
