Neosporin is a common home antibiotic ointment that is used in burns, cuts, and scrapes to prevent the entry of infections.
What’s the theory behind it?
Like toothpaste, Neosporin contains antibacterial properties effective in combating the Propionibacterium causing acne.
Why it won’t work
Inasmuch as Neosporin contains three active components- Bacitracin Zinc, Polymyxin B Sulfate, and Neomycin it still unable to solve your acne problem. Neosporin antibacterial bacteria can only kill gram-negative bacteria whereas the P.Acne bacteria is gram-positive.
The second reason why Neosporin isn’t effective in treating acne is because it is highly comedogenic. The base of this cream is majorly comprised of cottonseed oil and cocoa butter oil thus making the skin’s pores clog up fast thus rendering this product ineffective.
Instead of this ineffective home remedy, I would recommend the use of benzoyl peroxide. Since it’s not the best anti-acne treatment in the market use it as your last resort as it will help you kill the P.Acne bacteria and also prevent skin breakouts.
