What are cold sores?
Cold sores are an infection in the form of blisters that is caused by the Herpes Simplex virus type 1. After the organism gets infected, herpes simplex starts developing in the nerve ganglion (a cluster of nerve cells located in the autonomic nervous and sensory system) of the skin around the lips and the facial area. This infection occurs mostly in childhood, usually preceding a kiss by a carrier of the virus. The virus passes through the skin and locates in the nerve cells. It usually appears during menstrual cycles, colds, flu, excessive tension or when one has a weakened immune system.
Herpes is a contagious disease that is transmitted through contact with the affected area!
Most fever blister treatment methods belong to a group of medicines called antivirals. They are sold in the form of topical cold sore creams or ointments and are proven to provide the fastest results.
What are the active ingredients in a cold sore medication?
Multiple cold sore medications contain Zinc, Vitamin C, Acyclovir, Docosanol, Menthol, Lysine as active ingredients. According to Mayo Clinic, such ingredients will shorten the outbreak by as little as a few hours or as long as a day. Their purpose is to seal the ruptured blisters, healing the area affected and shortening the treatment period.
No matter what cold sore medicine you choose, you should carefully follow the directions prescribed on the cold sore medicine sheet!
How to treat cold sores on the lips
The skin on the lips is formed by 3 layers: epidermis, dermis and stratum corneum. The only difference between the skin on the lips and the other body skin is that the stratum corneum (the outermost layer) is much thinner. This is why this area is more sensitive and prone to any sorts of irritations.
Additionally, the skin on the lips lacks sebaceous glands and hair follicles, which makes it even more fragile.
All these characteristics make the appearance of cold sores on the lips area especially painful and irritating. This is why anaesthetic products (aiming to alleviate the pain and discomfort) are very suitable for the treatment of fever blisters on the lips.
Antiviral oral medications are usually prescribed to promote the faster healing process while preventing further outbreaks. Such include:
Note: As cold sores can easily spread in a moist environment, the first thing to do is keeping the affected area completely dry. For instance, if the fever blisters are located in the lips area, avoid licking them. A good cold sore medication for the lips is in thicker balm form – this way it will stay for longer.
Also, having a cold sore does not mean that you should reduce your water intake – on the contrary, you should even increase the consumption of water, as internal dehydration will result in slower healing and regeneration of the skin.
The most effective cold sore patches
Cold sore patches are an innovative, effective and easy-to-use technique to completely eliminate the unpleasant blisters. Of course, different brands use different active compounds but generally, cold sore patches combine antivirals and anaesthetic ingredients in order to simultaneously fasten the healing process and reduce the pain in the area affected. There are lots of patients saying patches are a great cold sore medicine, but the problem is that they are easily noticeable when applied to the facial skin.
Fever blisters can be successfully treated with cold sore patches at any stage of their development. However, the sooner you start your treatment, the faster the results.
These products should permanently act on the cold sore. The patches are usually invisible and very comfortable on the skin. They won’t provoke adverse reactions and will completely eliminate the cold sore within days.
The method is clinically proven to provide a safe and discrete effect, the fever blister will be immediately relieved from the common symptoms, associated with the outbreak. Herpes sufferers recommend the following cold sore patches:
Are creams recommended for cold sores
Cream-based cold sore medications aim to speed up the healing process and decrease the symptoms of the condition. Medically prescribed Zovirax, Valtrex, Famvir, Denavir fit into the most effective cold sore cream category, all of these are developed to shorten the treatment period. They are usually prescribed for more severe cold sore outbreaks, or in case the herpes infection has spread to other organs or systems.
Over-the-counter cold sore creams are also available and are usually a preferred option, as they are less aggressive. Such cold sore medicines are no different than other topical ointments used for the management of fever blisters. Among the fastest working cold sore creams available over the counter you can find:
Everyone's skin is unique, and even if you have chosen the best product for your skin condition, the containing ingredients may still cause some irritation, burning sensation, rash or allergy.
