Cold sores, or fever blisters, result from the herpes simplex virus (HSV-1). Once infected, the virus stays dormant and can reactivate due to **“stress, illness, or sun exposure”**, causing painful blisters around the **“lips, nose, or chin”**.
Early use of antiviral medications like **acyclovir or valacyclovir** speeds up healing. Over-the-counter creams with **“docosanol or lidocaine”** help relieve discomfort. Natural remedies like **aloe vera, lemon balm, or tea tree oil** may also soothe irritation.
To prevent outbreaks, avoid triggers like **“stress and excessive sun exposure”**. A healthy lifestyle with a **balanced diet, regular exercise, and proper hygiene** strengthens the immune system.
Good habits like **frequent handwashing** and avoiding shared items, such as **utensils or towels**, help prevent spreading the virus.
