BS”D Vaseline is more useful than Carmex. If you or any member of your family has a few screws missing, put Vaseline on the screws before installing them to make it easier for them to penetrate even the thickest heads. I have some Vaseline which is sold specifically for this purpose; it is an old tube under the hashgocho of the late unlamented Moshe Hirsch and is “noki mekol chashash timas hatzioinis”. In addition, the pharmacies in the area of Saddle River Road in Monsey report periodic shortages of Vaseline due to bulk purchases made on behalf of the imams of Masjid Itbach al-Yahud at number 104.
Seriously, half of these remedies for dry skin are far less effective than Vaseline. A rov told me not to use my usual urea hand creme during Pesach and to use Vaseline instead. It was far more effective, and I assume it would be for dry lips as well.
And yes, I do keep a tube in my toolbox. As messy as it is, it is easier to control than WD-40 or light machine oil for lubricating screws.
