A number of Oral & Maxillofacial Surgery departments carry out Surgical Dermatology.
This might seem odd at first glance, but the clinicians often have had first-hand experience of suturing up (sewing up) faces. Often, if one of the consultants in OMFS Department has an interest in Surgical Oncology, there is a concomitant interest in Surgical Dermatology.
Hence, in an OMFS Department you may have skin lesions removed / biopsied or have scars revised. Consequently, advice can be given regarding the care for scars, diagnoses of skin lesions etc.
I list below a number of websites that provide a broader and more profound knowledge of dermatology than this website hopes to provide.
