Acne medication and bacteria Featured science projectScience project video


The hypothesis that acne medications will inhibit the growth of acne causing bacteria (P.acne), is proven to be true.

There are many types of medication available for treating acne. A mild acne condition can be treated using topical creams. . More severe and persistent conditions may require oral antibiotics that assist in the alleviation of skin inflammation and in reducing  the population of P. acne bacteria.

Also consider

This science fair project can be repeated by varying the  types of P. acne medications used like Erythromycin, Azelaic acid and Oregano oil.

Will the antibacterial agents be more or less effective at varying  ambient temperature conditions? What about humidity? How does that affect the rate of bacteria growth?

Material availability:
Access to laboratory equipment (eg. petri dishes)
Safety concerns:

Always follow laboratory safety guidelines and always practice sterile technique when handling microbes. Never have any food or drink at your workstation and always thoroughly wash your hands with disinfectant soap or alcohol before leaving your workstation. Always dispose of used material in a biohazard bag. If none are available, the bacteria should be destroyed with bleach before being disposed of.
