In spite of variety of therapeutic options available for this cosmetically disfiguring condition, the treatment of this condition remains a challenge. Azelaic acid (AA) is a depigmenting agent which acts by inhibition of DNA synthesis and mitochondrial enzymes, thereby inducing direct cytotoxic effects on melanocytes. Glycolic acid (GA) peel is one of the most versatile agents in the treatment of melasma and lentigo solaris. GA peels alone or in combination with topical hypopigmenting agents has shown encouraging results. However, there is paucity of controlled trial demonstrating the efficacy of GA peels in conjunction with topical AA. \u0000Case: A 42-years-old female, works as a street vendor, came with dark brown spots on both cheeks, nose, chin and forehead that spreads to whole face since one year ago. She had a history of using contraceptives. From the dermatological examination, there were multiple well-circumscribed, irregular hyperpigmented macules that asymmetrical, with size ranging from lenticular to plaque on the maxillary, left buccalis, mentalis and frontalis region. We also found a numular dark brown hyperpigmented macules on right zygoma. She was diagnosed with melasma and lentigo solaris. The Melasma Area Severity Index (MASI) score was 25.6, which classified as moderate melasma. She was treated with 20% azaleic acid cream twice a day, broadspectrum sunscreen with SPF 50 and GA 20% peeling. \u0000Result: After 6 weeks of treatment, there were significant  improvement in both melasma and lentigo solaris.","PeriodicalId":184699,"journal":{"name":"Sumatera Medical Journal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125251066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ACE gene polymorphism has drawn a lot of attention from scientists and had been reported to have an indirect effect in increasing the ischemic stroke incidence through pathogenesis of hypertension and atherosclerosis.

The pathogenesis of acne vulgaris is multifactorial, from increased production of sebum, hyperproliferation of pilosebaceous follicles, colonization of Cutibacterium acnes, to inflammation process. The elevated sebum production which is often linked to oily skin type could result in acne vulgaris in adolescents. According to Baumann Skin Type, one of the parameters in categorizing skin type is having either oily or dry skin. Acne vulgaris is also found on dry skin. This research aims to find the association between skin types and acne  vulgaris. It is an analitic research with cross-sectional method. The data were acquired from 93 students of SMA Santo Thomas 1 Medan who fulfilled the inclusion criteria with stratified random sampling method. The collection of data were primarily carried out with dermatology examination and Baumann Skin Type questionnaire to determine the skin types. Then, they were analyzed with Chi-square test to see the relationship between skin types and acne vulgaris.      The obtained results show that 73 (78,5%) out of 93 students suffered from acne vulgaris with predominance being female (39,8%) than male (38,7%), and those in 15-year age group (38,7%). The most commonly observed skin type on samples is oily skin (79,6%).
