⚠️ Do not self diagnose! ⚠️ although these images are fairly representative, many skin conditions can look similar, and diagnosis often requires examination (sometimes with dermoscopy or even a biopsy).

If you notice something unusual on your skin seek professional help. #skinhealth #healtheducation #skinconditions
