Laser therapy offers a fast, comfortable, and highly effective way to treat cold sores at the earliest signs of tingling or once a blister has already appeared. Using targeted light energy, the laser reduces viral activity, minimizes discomfort, and stimulates natural healing, allowing the sore to clear up significantly faster than with traditional creams or medications. Treatment takes only a few minutes, is virtually painless, and often provides immediate relief. Many patients notice reduced swelling and quicker recovery within the first 24–48 hours. If you’re looking for a simple, non-invasive solution that accelerates healing and helps prevent future outbreaks, laser therapy is one of the most effective options available.
