Years ago I invested in a couple of dermatology textbooks. Although they have been updated many times, I still reference my old copies. You should be able to purchase on Amazon (even if you purchase an older edition)
Fitzpatrick’s Colour Atlas and Synopsis of Clinical Dermatology
or
Habif’s Clinical Dermatology: A colour guide…
Both textbooks I’ve found valuable when I can’t look online!
Cheers,
Kathleen
