Medicated Vaseline petroleum jelly works as a moisturizer, a diaper rash treatment and as a skin protectant, states Reader's Digest. It is also useful as an ointment for minor burns and scrapes, says the manufacturer's website. Apply medicated Vaseline petroleum jelly directly to the affected area after cleaning it, and apply a bandage.
Use as a moisturizer for rough spots, such as elbows and heels, says All You magazine. Spread the jelly around the hairline when applying hair color, to protect the skin from the dye. Apply the product liberally to wind burns or razor burns to relieve the pain. Warm the jelly in the microwave, and use as a massage ointment for back pain, according to One Good Thing By Jillee. Spread some jelly around the nostrils, and apply some inside the nostrils using a Q-tip, to block entry of pollen and other allergens.
Heal diaper rash by smoothing the petroleum jelly onto the affected area. Continue to use the product after healing is complete, to prevent another rash, says Reader's Digest. Spread it across a baby's eyebrows to stop shampoo from running into the eyes.
Robert Chesebrough developed Vaseline in 1865 as a burn and cut ointment. Other uses for the jelly evolved over time, according to Vaseline.us.
