Like you I did not want to use vaseline. In fact, I didn't use anything. I tried the vaseline once and for 20 min I was in the worst discomfort of the whole treatment. Like you, I am grateful for being able to use this treatment as I have had basal cell as well as melanoma. I did my face, chest and hands. After what I discovered on my chest, I would like to do my shoulders, arms and back. For some reason my doctor doesn't want me to do that, so I am going to ask why at my next visit. Hang in there, it will be over soon.
