Potencies to use with warts and moles?

I have used homeopathy with some success in the past 20 years both through my own research and with the help of two practitioners. I have had some success at treating my hay fever, irritable bowel and acid reflux.
One issue that has been disappointing is trying to deal with skin blemishes including moles warts and age spots. Some I have had all my life and some have more proliferated in aging. (I am now 66 years old)
Books I have read have increased my disappointment because they write as though warts etc are very easy to get rid of. My practitioner (George Skuby of Chicago IL who passed away in March at the age of 86) was more pessimistic, telling me that he did not have much success with them.
My question is, that if I choose a remedy in hopes it would eliminate moles and/or warts, would it be more effective in higher potencies or to go with lower?
My first practitioner did prescribe Medorrhinum 50M in the hopes of eradicating my hay fever. That was unsuccessful and created a severe aggravation, which was a month of severe insomnia. It did however, knock out a large mole on my right forehead.
That was about 20 years ago. I have taken many prescriptions since at both high and low potencies with many good results, but none have helped my skin blemishes.
