21 Jun 2022 --- Sao Paulo-based dermatologist reveals that the main contributors to dark circles are stress, aging and frequent unprotected sun exposure. Contrary to popular belief, not enough sleep is not the only cause of dark circles while it does enhance the appearance.“Dark circles can still arise due to vascular issues, genetics and even as a result of the aging process. To understand which treatment is most effective in each case, it is necessary to identify the type of dark circles for each person individually and pin down the main causes,” states Dr. Marcus Morais.
