For a minor skin infection, clean the area gently with water, apply an over-the-counter antibiotic ointment, and cover it with a bandage. That basic routine handles most small infections from cuts, scrapes, and bug bites. But the right approach depends on what kind of infection you’re dealing with and how serious it is, so it helps to know the details before you reach for anything in your medicine cabinet.
Clean the Wound First
Whatever you plan to put on infected skin, cleaning comes first. Sterile saline is the traditional gold standard because it won’t damage healing tissue, but clean tap water works just as well in most situations. One study found tap water actually reduced the risk of infection by 45% compared to saline when used to irrigate sutured wounds. Multiple other studies comparing the two found no significant difference in infection rates for both acute and chronic wounds.
Run clean water over the area for a few minutes to flush out debris and bacteria. You can use a mild soap around the wound but try to keep soap out of the wound itself, as it can irritate raw tissue. Pat the area dry with a clean cloth or gauze before applying anything topical.
Over-the-Counter Antibiotic Ointments
The most common product people reach for is triple antibiotic ointment, which combines three active ingredients that work against different types of bacteria. It’s widely available without a prescription and is applied two to five times a day for minor skin infections. There’s also a simpler two-ingredient version that skips one of those components, and single-ingredient ointments that use just one antibiotic.
Here’s something worth knowing: the ingredient neomycin, found in triple antibiotic ointment, causes allergic contact dermatitis in roughly 3.2% of adults and 4.3% of children. If you notice that your skin gets more red, itchy, or rashy after applying it, you may be reacting to the ointment itself rather than seeing the infection worsen. Switching to a neomycin-free option usually solves the problem. Plain petroleum jelly is another reasonable alternative for very minor wounds. It keeps the area moist and protected, which supports healing even without antibiotics.
When You Need a Prescription
Over-the-counter ointments work for preventing and treating mild infections, but they have limits. If the infection isn’t improving after a few days of home treatment, or if it’s spreading, your doctor will likely prescribe something stronger. Prescription-strength topical antibiotics are effective against resistant bacteria, including MRSA, that OTC products can’t reliably treat. In lab studies, prescription formulations performed comparably to OTC combinations against common staph bacteria, but they have the added advantage of working against strains that have developed resistance to standard antibiotics.
For deeper or more widespread infections like cellulitis, topical treatments alone won’t be enough. These infections typically require oral antibiotics because the bacteria have moved into tissue layers that a surface ointment can’t reach.
Make Sure It’s Not a Fungal Infection
Antibiotic ointments only work on bacterial infections. If your skin infection is caused by fungus, no amount of antibacterial product will help. Fungal infections tend to look different: they often appear as a defined rash pattern (think ringworm’s circular shape or athlete’s foot between the toes), may cause itching more than pain, and can make nails turn yellow, brown, or white and become thick or cracked. A white coating in the mouth or throat also points to fungus, not bacteria.
Bacterial infections, by contrast, tend to cause a spreading area of redness, warmth, swelling, and pain. The skin may look pitted like an orange peel, and you might see pus or cloudy drainage. If your infection looks more fungal, you need an antifungal cream or powder instead of an antibiotic ointment.
Medical-Grade Honey
Medical-grade manuka honey is a legitimate option for infected wounds, not a folk remedy. It works through several mechanisms at once: it produces hydrogen peroxide when applied to skin, has a naturally low pH that inhibits bacterial growth, and contains a compound called methylglyoxal that disrupts bacterial biofilms. Biofilms are the protective colonies bacteria build to shield themselves from treatment, and they’re a major reason some infections become chronic and hard to clear.
Lab research has shown manuka honey is active against MRSA, strep, pseudomonas, and E. coli. It can both prevent biofilms from forming and break down established ones. The key is to use medical-grade products specifically designed for wounds, not the jar of honey from your kitchen. Medical-grade versions are sterilized and standardized for antimicrobial strength. They’re available as gels and impregnated dressings at most pharmacies.
How to Cover Infected Skin
After applying your chosen treatment, covering the area matters. A good dressing keeps the wound moist (which speeds healing), absorbs any drainage, allows some air exchange, and prevents bacteria from the environment from getting in. For most minor infections, a simple adhesive bandage or gauze pad secured with medical tape does the job. Change it at least once a day, or whenever it gets wet or dirty.
If the wound is producing a lot of drainage, you may need a more absorbent dressing. Semi-occlusive options like silicone-coated net dressings strike a good balance, keeping moisture in while letting excess fluid escape. Fully sealing an actively infected wound can trap bacteria and fluid, so avoid airtight coverings unless specifically directed by a doctor.
Signs the Infection Is Getting Worse
A minor skin infection that responds to home treatment should start looking better within two to three days. The redness should shrink, the pain should ease, and any drainage should decrease. If instead you notice the redness spreading, red streaks extending outward from the wound, increasing pain, or swelling that keeps getting worse, the infection is moving deeper or into surrounding tissue.
Certain signs point to a situation that needs emergency care: a rash that’s changing rapidly, fever, or skin that’s becoming increasingly swollen, painful, and hot. These can indicate cellulitis or early sepsis, where bacteria have entered the bloodstream or lymph system. Cellulitis spreads fast and can move into deeper tissues if left untreated. A topical ointment won’t address an infection at that stage.
