Cold sores, caused by the herpes simplex virus (HSV-1), often reappear after the initial infection due to triggers like stress, illness, or sun exposure.
Antiviral medications (e.g., acyclovir or valacyclovir) can speed up healing, while over-the-counter creams (e.g., docosanol or lidocaine) provide relief. Natural remedies like aloe vera, lemon balm, and tea tree oil may soothe irritation. To prevent outbreaks, avoid triggers, maintain a healthy immune system, and practice good hygiene to reduce flare-ups and prevent spreading the virus.
