Is it removing moles with tea tree oil possible? Regardles to some clinical trials I cannnot see how it can remove some in sito dysplastic nevus?

Wouldn't count on it. No matter what you read either on the internet or in a journal about tea tree oil, i definitely would not rely on it to treat any type of dysplastic nevus. Even a lesion in situ! it is always best to excise (have them surgically removed) and send to the pathologist, so you can have proof that the entire lesion is out.
