  Chinese traditional opera (Xiqu) performers often experience skin problems
due to the long-term use of heavy-metal-laden face paints. To explore the
current skincare challenges encountered by Xiqu performers, we conducted an
online survey (N=136) and semi-structured interviews (N=15) as a formative
study. We found that incomplete makeup removal is the leading cause of
human-induced skin problems, especially the difficulty in removing eye makeup.
Therefore, we proposed EyeVis, a prototype that can visualize the residual eye
makeup and record the time make-up was worn by Xiqu performers. We conducted a
7-day deployment study (N=12) to evaluate EyeVis. Results indicate that EyeVis
helps to increase Xiqu performers' awareness about removing makeup, as well as
boosting their confidence and security in skincare. Overall, this work also
provides implications for studying the work of people who wear makeup on a
daily basis, and helps to promote and preserve the intangible cultural heritage
of practitioners.
