Polysporin or Neosporin: What’s the Difference and When to Use?

When it comes to treating minor cuts, scrapes, and burn wounds, two popular over-the-counter ointments come to mind: Polysporin and Neosporin. These antibiotic ointments are widely used to prevent infection and promote healing. However, understanding the difference between the two is paramount in helping you make an informed decision on which to use—polysporin vs. neosporin—in different situations.

When to Use Polysporin

First off, let’s start with this: What is polysporin? 

Polysporin is a topical antibiotic ointment that primarily contains two key ingredients—polymyxin B and bacitracin. These two antibiotics work in tandem to prevent bacterial infections in minor wounds. Polysporin is a preferred choice for superficial skin injuries that are at risk of contamination. 

You should look to use Polysporin when: 

  • For cuts and wounds: It is effective in preventing bacteria from growing in those wounds and helping them heal without complication. 
  • For abrasions and scratches: Whether you’ve grazed your knee or experienced a mild abrasion, applying Polysporin can provide a protective barrier against bacteria. 
  • Preventing Infection: If you have a wound that is prone to infection due to the location or nature of its severity, Polysporin can be a proactive measure to stave off bacterial growth.

When to Use Neosporin

Neosporin is like Polysporin in the sense that it is a popular antibiotic ointment designed to prevent infection in minor cuts and wounds. However, the key difference between two lies in its formula. Neosporin contains three active ingredients (vs. two for Polysporin), the duo of polymyxin B and bacitracin, as well as, neomycin. Neomycin is an additional antibiotic that provides broad coverage against bacteria. 

You Should Look to Use Neosporin When:

  • Dealing with a broader range of bacteria: The inclusion of neomycin in Neosporin makes it applicable in a wider spectrum of bacterial infections compared to its counterpart, Polysporin.
  • If you have an allergic reaction to bacitracin: While Neosporin has traces of bacitracin, the formula does not have as much as Polysporin. In such instances where an allergic reaction occurs as a result of Polysporin, Neosporin is a safer alternative because of the presence of neomycin. 
  • Healing burns: Neosporin is often recommended over Polysporin for the treatment of minor burns because it not only protects against infection but also aids in the healing process.

As always, if injuries grow too severe and begin to become infected you should call for emergency or non-emergency medical transportation (depending on the severity and status of the patient) and seek an expert’s opinion. 

Which is Better?

Determining whether Polysporin or Neosporin is better depends on various factors, including personal preference, allergies, and the specific nature of the injury. Both ointments are effective in preventing infections, but ultimately the choice comes down to individual circumstances. 

If you’re allergic to bacitracin and require an antibiotic ointment for a minor cut, Polysporin may be the preferred option. On the flipside, if you’re dealing with a broader bacterial issue, or burn, Neosporin is probably your best bet. 

Common At-Home Injuries Requiring Polysporin or Neosporin

  1. Cuts and Scrapes: We’ve covered thus far that both Polysporin and Neosporin are suitable for treating minor cuts and scrapes. However, if the cut is prone to infection due to its location or exposure, Polysporin’s dual antibiotic formulation may have that extra layer of protection you’re looking for. 
  2. Burns: When it comes to minor burns, Neosporin is the move. The combination of neomycin, bacitracin, and polymyxin B in its formulation makes it a more comprehensive choice for burn treatment. But remember, if a burn is more severe, further medical assistance may be required and recommended.
  3. Contact Dermatitis: If you’re dealing with contact dermatitis, caused by either an allergic reaction or irritation, both Polysporin and Neosporin can be used to prevent infection in the case of open sores or broken skin. You should contact a medical professional if seeking further clarity on which option is best for your specific case. 


In conclusion, the choice between Polysporin and Neosporin, understanding their differences, and knowing when to use each is crucial for effective wound care. While both ointments serve the common purpose of preventing infections in minor injuries such as cuts, scrapes, and burns, individual preferences and allergies play a significant role in determining which is better suited for a specific situation. Whether you opt for Polysporin or Neosporin, having one of these antibiotic ointments in your first aid kit can contribute to prompt and efficient wound healing.
