Xerosis: a focus on black skin
Doctors should provide evidence-based information about emollients for patients of African origin, since both hyperpigmentation and lichenification are different for black skin types than white or Asian skin types.
Identification and care of external genital warts
Genital warts are a symptom of certain types of human papillomavirus (HPV) infection and result in significantly reduced quality of life. A number of treatment options are available, but efficacy rates vary dramatically between treatments.
Banish fungal nail infections for good

Sun protection

Superficial fungal infections of the nails
Superficial fungal infections tend to infect the stratum corneum layer of the skin, the hair or the nails, causing various types of clinical symptoms, which can be very distressful to the patient
