Can lipstick infect AIDS? Will lipstick have HIV?

Lipstick will not be infected with HIV. The reasons are as follows: First of all, the virus content in saliva of AIDS-infected people is very small, even if saliva touches lipstick and is contacted by healthy people, it is not enough to cause infection of new individuals. Secondly, after leaving body fluids, HIV will soon lose its activity in a dry environment. Third, the intact oral mucosa of healthy people has a strong barrier function, which can prevent the invasion of HIV. Although there are very accidental cases in theory, such as a bleeding wound on the lips of an HIV-infected person, and blood on the lipstick, and then the lipstick is used by a healthy person, and the healthy person happens to have a bleeding wound on his lips, then the virus in the infected person's blood may enter the healthy person through the wound and cause infection, but the probability of this happening is extremely low and almost impossible.
