Vaseline traces its roots to the 19th century, when Brooklyn chemist Robert Augustus Cheeseborough first developed it as a natural remedy for skin abrasions in 1869. A mixture of paraffin and microcrystalline wax and mineral oil comprises petroleum jelly. It prevent water from escaping the body through the skin and drying it out.
Moisturizes Skin
Vaseline is an occlusive moisturizer. According to acneguide.com, occlusives form a sealant that locks water into the skin, preventing dryness. It can also resolve dryness by preventing further water loss from the skin, allowing the skin to repair itself from within.
Softens Skin
Vaseline contains paraffin wax. According to the Stevens Institute, a medical day spa in Los Angeles, paraffin wax smooths and softens the skin.
Repairs Cuts, Abrasions and Chapped Lips
One of Vaseline's original uses was healing cuts and scrapes on the skin. The occlusive properties of Vaseline seal the skin breakage. This prevents bacteria or impurities from entering the wound, allowing the body's natural healing properties to work without interruption. Applying it to the lips works as a balm, soothing the surface and preventing moisture from escaping.
Lubricates a Thermometer
Vaseline is also useful as a lubricant. Heidi Murkoff's website whattoexpect.com recommends using petroleum jelly when taking a child's temperature rectally. After cleaning the thermometer, just coat the tip with petroleum jelly before inserting the thermometer anally.
Other Uses
Vaseline can also be used as a beauty aide. Thebeautybrains.com, a website authored by cosmetic chemists, suggests using it to extend perfume and seal split ends. Rubbing a thin layer of Vaseline on the forearm holds a fragrance and makes it last longer. Vaseline can also seal split ends on strands of hair, delaying a trip to the salon.
