When the external layer of our skin -- the stratum corneum, part of the epidermis -- becomes dry, chapped and itchy, it loses its ability to act as a protective barrier. Skin becomes prone to cracks, sensitivity and even infection. Pure petroleum-based ointments are hypoallergenic, noncomedogenic, nonirritating, nonsensitizing and contain no added colors or fragrances -- all of which makes these moisturizers good for babies (on diaper rash), adults and everyone in between. Daily use on our bodies not only heals dry skin by sealing in moisture but protects skin from further damage by acting like a barrier against the elements.
To get the most bang from petroleum jelly, add it to a daily skin care routine, best used as a moisturizer applied to damp skin after a shower.
