BACKGROUND: Although @entity2318 is a permanent sequela that may be induced by improper management of active @entity75 , @entity1 behavior patterns and @entity3596 regarding acne are unclear. The aim of this study was to identify @entity3596 and behavioral patterns concerning acne and @entity2318 of @entity1 having acne and differences between those with and without @entity2318 . METHODS: The survey was performed via smartphone application for 900 @entity1 in their second to fourth decade having current or previous @entity75 . They were further categorized into two groups based on the presence of @entity2318 (scar and scarless groups) with no statistical difference in demographic composition. RESULTS: The mean age of all @entity1 was 24.6      5.3. The scar group had a longer disease duration (4.9  years) than those of the scarless group (2.2  years). @entity1 in the scar group thought that acne scarring affected psychosocial aspects more negatively compared with those in the scarless group. @entity1 in the scarless group visited dermatology clinics earlier than those in the scar group. In the scar group, 62.1% of @entity1 have never had their @entity2318 treated medically. Most (88.6%) @entity1 from both groups believed that non-dermatologic treatment caused side effects or aggravated their acne. CONCLUSIONS: @entity1 with @entity2318 tended to treat their acne and @entity2318 improperly, which could negatively affect their daily lives. Acne scars are sequelae of acne and should be regarded as a distinct disease entity, requiring a @entity1 's early visit to dermatologic clinics.
