Studies have shown that 70 to 96% of people have experience with acne during their lifetime, and about 30% require treatment. There are many ways to treat acne. In recent years, it has been proposed that the effects of traditional medical therapy are more remarkable in various fields of photodynamic therapy. However, compared with cumbersome instruments and equipment, hand-held therapeutic devices are still in their infancy at home and abroad. Therefore, the purpose of this study is to explore how consumers feel when using handheld therapeutic devices and to provide further design recommendations. In this study, 3D printed handheld device samples were tested for different parts and collected and analyzed by questionnaire. The results of the study found that there was a significant difference in the satisfaction of the same sample used at different angles and at different locations, and the size of the sample was related to the subjective preference of the user. In terms of appearance, testers aged 21 to 25 prefer samples with small appearance and design sense; testers aged 26 to 30 are mainly based on moderately sized samples; testers from 31 to 35 years old are for products. The CP value is more focused and prefers a larger sample. The overall sample size of Ø40 is favored by the public. In terms of comfort at the three test sites. In the cheek test, the sample angle of 180° is the best, and the worst is 150°; in the nose test, the angle of 210° is the best, and the worst is 150°; in the chin test, the angle of 150° is the best. The worst is 210°. The findings of this study provide a reference for designers to design their products. havehav
