Can vaseline use as face moisturizer? Has anyone reported allergic reaction to vaseline?

Stay away. Vaseline does not moisturize. The petroleum jelly can an allergic reaction. People get fooled because vaseline can help to keep a moisurizing cream on, but it does not moisturize itself.
Controversial. Many anecdotal reports of successful use of vaseline as moisturizer (sounds plausible since ointments moisturize better than creams or lotions or gels), but there is concern that, as a petroleum product, it may be associated with (breast) cancer or other cancers. Some state it clogs pores, while others declare it helps remove makeup. Ask dermatologist for a specialist's opinion.
