研究表明，成年人的痤疮发病率逐渐增高。不同于可在青春期结束后自愈的“青春期痤疮”，成年人的痤疮病程更长，更难治愈，会对患者的心理和情感产生负面影响。此外，痤疮与其他疾病的不同之处在于，它的“可视性”和“呈现性”。皮肤，是外显的身体部位，痤疮所造成的皮肤瑕疵完全暴露在社会性目光的审视之下。因此，不同于普通疾病，痤疮的意义暧昧纷杂。从病理学角度来说，痤疮所造成的身体性疼痛是有限的。然而，痤疮患者所遭受的疾痛体验，主要来自社会和文化性压力。

首先，本研究通过对4所医院皮肤科门诊部的参与观察，和对20名受访者（包括18名患痤疮的成年人）的深度访谈，归纳了受访成年痤疮患者的共同特征，呈现了成年痤疮患者真实的疾痛故事。

其次，本研究探究了痤疮患者逃避“照镜子”的行为背后的潜在逻辑。本研究发现痤疮使得患者的社会想象、身体想象和自我想象都发现了歪曲。为了应对疾病，痤疮成年患者形成了“消极身体”的特殊身体想象，并且通过控制身体和调整心态的“自我技术”来重塑自我。

最后，本研究反思了痤疮的社会污名和痤疮的疾病化。本研究发现痤疮患者在遭遇社会污名时，是难以反抗或“顶嘴”的。此外，18世纪末痤疮在西方被确定为一种皮肤病，是由于痤疮意义不明，无法分类，而现代性话语要整合一切事物与现象的企图，促使了痤疮的疾病化。

Acne is predominantly known as a skin disorder of the adolescent population. However, current research indicates that the prevalence of adult patients with acne. Adult acne is a chronic condition that appears to impact the quality of life in adult patients more than in their younger counterparts with considerable psychological, social, and emotional impacts.

First of all, this research observed the dermatology department in four hospitals, and carried out an in-depth interview with 20 respondents (including 18 adult patients). Based on the interview, this study presents the illness narratives of adult patients, and summarizes their basic characteristics.

Second, this research explores the underlying logic behind the behavior of acne patients not looking in the mirror. This study found that adult patients' social-imagination, body-imagination and self-imagination were distorted after suffering from acne. In order to cope with the disease, adult patients hold a special body imagination of “negative body”, and reshape themselves through the technologies of the self, including body control and emotion regulation.

At last, in this research, adult patients, after encountering the social stigma, can hardly fight back or talk back. Additionally, the meaning of acne is ambiguous and can not be integrated into the order of normal and abnormal. The modern discourse of cutting and integrating all things and phenomena promotes the birth of clinical medicine and makes acne a disease.
