I think from 100 out of 90 people must use vaseline petroleum jelly during the winter season! I just cant live without it. The jelly keeps our skin moisturize. My skin always become dry during winter and my lips becomes so rough that they start bleeding sometimes and hence I prefer Vaseline jelly to apply on my lips and also to skin.It always improve my dryness of lips and makes them moisturize and shiny!
It is so cheap to purchase and you can buy from nearby shops or medical centers.
If you too are having a problem like drying the lips or becomes rough then must use vaseline jelly. there is no any adverse effect of this jelly.
