Is it permissible to specialize in dermatology despite the issues surrounding skin cleansing, peeling, fillers, and the dispensing of alcoholic and cosmetic medications and creams? And would the income resulting from examining women and dispensing these creams be unlawful?

It is permissible to specialize in dermatology, and the occurrence of some Sharia violations by some doctors does not prevent this, such as impermissible cosmetic surgeries, or dispensing unlawful medications, or impermissible mixing. These violations are present in all medical specializations, and it is incumbent upon the physician to fear Allah and avoid prohibitions. And his salary is lawful as long as he performs his required work.
