Periorbital hyperchromia (dark eye circles) is a recurrent complaint in dermatologic consultations, as it interferes with patients’ self esteem. The eyes are central in the communication process, and dark eye circles are very noticeable and make the face look tired; thus they have a considerable impact on patients’ quality of life. Although many treatment options are available, publications on periorbital hyperpigmentation are scarce, and the vast majority lack a sound scientific basis to prove their efficacy and duration. This article analyzes the palpebral region’s anatomy and periorbital hyperchromia’s epidemiology, etiopathogeny, and treatments recommended in the literature.

A Covid-19, doença causadora de síndrome gripal e insuficiência respiratória aguda, vem demonstrando provocar danos a diversos outros órgãos e sistemas. Várias manifestações dermatológicas já foram descritas. Relatamos um quadro de alopecia areata (AA) desencadeada possivelmente pela Covid-19 em paciente que, apesar de ter seu RT-PCR para SARS-CoV-2 negativo, apresentou IgM reagente e sintomatologia clássica relacionada à doença. Acreditamos que a Covid-19 possa ter desencadeado resposta imunológica autoimune, com a consequente produção de interferons, que levou ao quadro de AA.

Atrophic acne scars result from an abnormal wound-healing response that can be treated with microneedling (MN). Insulin may play a role in wound healing. The effectiveness and safety of combining MN with topical insulin as an alternative therapy for atrophic acne scar revision have not yet been widely reported. We report the case of a 33-year-old woman with an atrophic acne scar on the middle third of her face. The patient was treated with MN and topical insulin for four sessions at two-week intervals. MN plus insulin can be considered an alternative for acne scar revision.
