this is a serious response. medical professionals do not provide potents that make people ugly for a day or at least not since the dark ages so you may need to see a theatrical make-up artist.
i want to be ugly. i want some kind of potion that gives me rashes and red spots all over my body for one day. please. i'm not happy looking like a beautiful guy. i want to be ugly and not stand out in the crowd positively. is there something i can take once per day that will give me all kinds of ugliness? . i see people getting rashes from all sorts of places but not on purpose. i don't want to poison myself too much by experimenting so i need help with having a not-too-painful way to do this. please. this is serious.
