Skin Infection Treatment in Princeton and Lawrenceville, NJ
A skin infection occurs when bacteria (and less commonly fungi or viruses) enter through a break in the skin. It may appear as redness, warmth, swelling, tenderness, or drainage—and in some cases, symptoms can progress quickly.
Common types include cellulitis, abscesses, infected cuts, and staph infections. While many skin infections are mild and respond well to treatment, some require prompt medical care to prevent complications.

WHO THIS AFFECTS + WHY IT HAPPENS
Skin infections can affect:
- Athletes (especially contact sports)
- Individuals with cuts or abrasions
- People with diabetes
- Patients with weakened immune systems
- Children and older adults
Why It Happens
Bacteria normally live on the skin. When there is a break—such as:
- A cut or scrape
- An insect bite
- A surgical wound
- Cracked or dry skin
—bacteria can enter deeper tissue and multiply.
Common bacterial causes include Staphylococcus and Streptococcus species.
Risk Factors
- Diabetes
- Poor wound hygiene
- Recent trauma
- Chronic skin conditions
- Shared athletic equipment
- Obesity
- Circulation problems
In athletic communities like Princeton and West Windsor, close contact and shared locker room spaces increase risk of certain infections.
