Who diagnoses skin diseases? doctors & dermatologists? is this correct?

I think so I can't think of anyone else that would diagnose skin disorder's.

Don’t know if this help but here is some info

A dermatologist is a medical professional who specialises in diagnosing, treating and preventing skin conditions. Common skin conditions treated by dermatologists include skin cancer, acne, psoriasis, eczema, dermatitis and warts.

Hope this helps
