Introduction: Periorbital hyperchromia or "dark circles" is a common complaint, due to the fact that it interferes with patients' self-esteem. Objective: To evaluate the prevalence of periorbital hyperchromia and its possible etiopathogenetic factors in a population sample drawn from a state and university dermatology service in Porto Alegre, Brazil. Methods: Cross-sectional, prospective study. Data collection questionnaire given to patients who visited the Dermatology Department of UFCSPA, from November 2011 to April 2012. Results: From a total of 220 investigated patients, there was a predominance of women with skin phototypes 2 and 3 and a mean age of 42.2 years.The use of sunscreen and corrective makeup were seen in 59.8% and 40.4% of studied patients, respectively. Presence of septal deviation was observed in 6.8% of patients, snoring at night in 48.4%, asthma in 15.1%, rhinitis in 44.7%, atopic dermatitis in 11.2%, mouth breathing in 20.1% and other types of allergy in 28.6%. Half of the sample mentioned sleeping 5 to 7 hours per night. Smoking, alcohol consumption, and physical activity were reported by 19.2%, 32.9% and 42.9% of patients, respectively.A family history of dark circles was described in 63.7% of cases. Conclusions: periorbital hyperchromia predominated in women of low skin phototypes, during their 4th decade of life and who reported daily use of sunscreen, physical inactivity, alcohol consumption, smoking habit, allergies, sleep deprivation, and a family history of dark circles.
RESUMO
Introduction: Periorbital hyperpigmentation is a multifactorial dyschromia that involves the eyelid's vascularization and melanin hyperpigmentation. Objective:To compare the efficacy of 2.5% thioglycolic acid, 2% hydroquinone, 2% Haloxyl, and 10% thioglycolic acid peel in the reduction of dark circles. Methods: Eighty patients were divided into four groups. Groups 1, 2, and 3 underwent treatments with 2.5% thioglycolic acid, 2% hydroquinone, and 2% Haloxyl, respectively. Group 4 underwent five biweekly sessions of chemical exfoliation with 10% thioglycolic acid. All patients were evaluated by two physicians after the treatment: the one who performed the treatment, and another who was blinded to the outcome. The assessment was carried out using photographs and a clinical satisfaction questionnaire distributed to the patients. Results: The best results occurred in Groups 1 and 2. Group 3 had slightly inferior results, possibly due to the low concentration used. Group 4 had the least significant results, however this outcome may have been influenced by the higher age of the group members and the lack of daily use of medications. Conclusions: There is still not an ideal treatment for dark circles, with the currently available therapeutic resources only alleviating the difference in color between the lower eyelids and the rest of the face.

RESUMO
A hipercromia cutânea periorbital ou "olheira" é queixa comum nos consultórios de dermatologia por interferir na autoestima dos pacientes. Os olhos são o centro das atenções na comunicação, e a "olheira" dificilmente passa despercebida, proporcionando à face aspecto de cansaço, causando importante impacto na qualidade de vida. Há poucas publicações na literatura sobre hiperpigmentação periorbital e, embora as opções de tratamento sejam muito vastas, a maioria carece de embasamento científico que comprove sua eficácia e duração. Este artigo aborda a anatomia da região palpebral, a epidemiologia, a etiopatogenia e os tratamentos propostos na literatura para a hipercromia periorbital.
