What causes cold sores?

Cold sores are primarily caused by herpes simplex virus type 1 (HSV-1), with HSV-2 also capable but less common. The virus, which remains in the body for life, can be spread through direct contact with an infected person’s skin or saliva. Triggers for outbreaks include stress, illness, sun exposure, hormonal changes, fatigue, and extreme weather. Not all carriers experience cold sores, but those who do may see varying severity and frequency of outbreaks, influenced by their immune system and trigger exposure.

What is cold sore laser treatment?

Cold sore laser treatment is a modern therapeutic approach that uses laser technology to treat cold sores, also known as herpes simplex virus lesions. This treatment involves directing a focused beam of light at the site of the cold sore. The light energy from the laser helps to reduce inflammation, alleviate pain, and promote faster healing of the lesions.

The laser works by penetrating the skin and targeting the virus directly, which can help to prevent the cold sore from fully developing if caught early enough. Additionally, laser treatment can enhance the local immune response, helping to prevent further outbreaks in the treated area. This method is generally quick, with each session lasting only a few minutes, and typically does not require anesthesia. Many patients report immediate pain relief and a reduction in healing time compared to traditional topical or oral treatments.

Cold sores vs canker sores — What's the difference?

Cold sores and canker sores are often confused due to their similar names and the fact that they both appear in or around the mouth. However, they are distinctly different in several key ways:

1. Cause: Cold sores are caused by the herpes simplex virus (usually HSV-1), making them contagious. Canker sores, on the other hand, are not caused by a virus and are not contagious. The exact cause of canker sores is not well understood but may be related to factors like stress, minor mouth injuries, acidic or spicy foods, vitamin deficiencies, hormonal changes, or autoimmune disorders.
2. Location: Cold sores usually appear on the lips, around the mouth, and occasionally on the nose or cheeks. Canker sores occur inside the mouth, typically on the soft tissues like the inside of the lips and cheeks, the base of the gums, under the tongue, or on the roof of the mouth.
3. Appearance: Cold sores start as blisters that eventually burst and crust over. They are generally painful and filled with fluid. Canker sores appear as small, round, or oval ulcers with a white or yellow center surrounded by a red halo. They are also quite painful, especially when talking or eating.
4. Treatment: Treatment for cold sores often includes antiviral medications, which can reduce the severity and frequency of outbreaks. Over-the-counter treatments and prescription drugs can help manage symptoms. For canker sores, treatment typically involves over-the-counter topical treatments, mouth rinses, and oral medications to reduce pain and inflammation. In some cases, dietary adjustments may be recommended.
