hi, im in grade 10 and im doing a science fair
testing how the pH levels of rainwater, tap water, and bottled water
affect the acne bacteria (p. acnes)
the problem is, it is IMPOSSIBLE to acquire the p. acnes
do you know how i can possibly get the bacteria?
can rub my skin with swabs and get the bacteria that way
to put into a petri dish?
THank you so much
please answer ASAP
