I have not applied it to my face. I apply it along the spine and on the Thymus gland area. I put some also on my throat just under the thyroid. This clears and brings up mucous and opens the nasal passages nicely. It only stings when appled to the underarms but for a brief time.
Some oils are stronger than others so results and sting effects may vary. Topical application may or may not remedy a fungus condition. I would use Humaworm or something like Samento for any systemic condition. Also zinc creams applied topically are excellent for killing local infections such as ringworm.
