I wish to convey that no amount of petroleum jelly will help at this juncture. I suggest that you use [Apply] pure forest honey during day and clarified butter liberally during nights. See the result in about a week.
with best regards,
In case you need the right way of preparing Clarified butter / Ghee [as it is called in India]
please read thru - http://www.food-india.com/ingredients/i001_i025/i007.htm
Or else you can source it at any of the South Asian [Indian/Sri Lankan/Pakistani.... stores] shops. Honey is also available there. "Dabur" honey is available all over US and Manuka honey if its easily available is good, no doubt. Usually the goodness of honey comes from the forest from which its sourced / collected as the good medicinal properties come from the various flowers nectors growing over there. Cultivated bee farm honey may not be having that much quality.
Good to see that you have taken pains to start the advice earnestly and believe me this itself is half battle won. good Luck and God bless.
with healthiest regards,
