Common Cold Sore Symptoms

Common cold sores, also known as oral herpes or fever blisters, are caused by the herpes simplex virus (HSV-1). Most people experience infection in childhood or young adulthood, and the infection lasts throughout a person’s lifetime. Cold sores appear as small, fluid-filled blisters on or around the lips, though they can also develop on the nostrils, chin, or inside the mouth. They typically develop in stages, each characterized by specific symptoms.

Cold Sore Stages


Tingling or Itching Sensation
(Prodrome Stage):

This initial stage occurs one to two days before a visible outbreak, and most individuals will experience a tingling, burning or itching sensation around the affected area, indicating an impending cold sore outbreaking. Some individuals may also experience a fever, sore throat, swollen glands or bad breath during this stage.

Blister Formation
(Vesicle Stage):

After the prodrome stage, small, red bumps begin to emerge, which soon develop into fluid-filled blisters. These blisters are usually tender and can be painful to the touch, while the skin around the blisters might become red and swollen.

Rupture and Ulceration
(Ulcer Stage):

Within a few days, the blisters break open, releasing a clear fluid that contains the active virus. This stage is often the most uncomfortable, as the open sores can be painful and may cause discomfort when eating, drinking, or talking.

Crusting and Scabbing
(Crust Stage):

As the open sores begin to heal, a crust or scab forms over them. The scab is a protective layer that shields the healing skin underneath. During this time, the cold sore may feel tight and itchy.

Healing and Resolution
(Healing Stage):

Over the next two weeks, the scab gradually falls off, revealing new skin beneath. The healing process is usually complete once the scab has disappeared, and the area may still be slightly pink for a while.

Cold Sore Trigger Alerts

If you want to stop a cold sore when you feel it coming on, apply Clera at the first sign of a tingling sensation to prevent an outbreak.

From stress to sun exposure and weak immune systems, there are a few common factors that can trigger cold sore outbreaks. That’s why we’ve put together some practical tips to help you better protect yourself when you feel a cold sore coming on. And remember: always apply Clera at the first sign of a tingling sensation to prevent an outbreak.

Stress Icon | Icône Stress

STRESS

Emotional and physical stress or fatigue can wear down your immune system, and can activate the virus from within the nerve cell. To reduce your stress levels, it’s important to get enough sleep, carve out time for physical activities, eat a balanced diet and talk to a loved one about anything that might be weighing on your mind in your personal or professional life.

Weather Icon | Icône Température

EXTREME WEATHER

Exposure to sunlight, sunburn, ultraviolet light sources and dryness, cold wind and chapping may trigger a cold sore. Invest in a hydrating SPF lip balm (with aloe if possible) and apply it frequently during the summer and winter months to help prevent an outbreak.

Illness Icon | Icône Maladie

ILLNESS

Common colds and illnesses weaken your immune system and trigger cold sores, so it’s vital that you keep yourself hydrated and healthy with a balanced diet to ensure your body is getting the nutrients it needs to fend off potential outbreaks.

Pregnant Icon | Icône Enceinte

MENSTRUATION OR PREGNANCY

Cold sores tend to appear when a woman has her period or during pregnancy. Apply Clera to keep the cold sore from flaring up.

Injury Icon | Icône Blessure

INJURY

Physical traumas to the sensitive areas on and around your lips, such as bites, scrapes or cuts, including forms of dental injections or tooth extractions, can also trigger cold sore outbreaks. If you injure your lip, treat the area immediately with the appropriate remedy to prevent infection.

Please note that Clera is designed for lips and face only and should not be ingested.

Solutions for Maintaining Healthy Lips

Did you know that your lip health is directly connected to your lifestyle?

While various forms of stress, changes in weather and injuries to your lip area can spark a cold sore outbreak, there are several steps you can take to help keep your lips looking their best.

HYDRATION

Dehydration can affect your immune system and can cause dry mouth/chapped lips, which may trigger an outbreak. Men should drink approx. 3.7 litres of water a day and women should drink approx. 2.7 litres a day**. But it’s also important to know your body and activity levels, as your water intake could change. Getting enough fluids helps your kidneys filter waste and protects you from fatigue (a cold sore trigger).

** The National Academies of Sciences, Engineering, and Medicine..

Diet

Did you know that your lip health is linked to your diet? Eating processed foods can take a toll on your immune system, which can lead to cold sore outbreaks. Try to limit or eliminate your intake of refined sugars and processed foods, and focus on healthy greens, whole grains and consuming natural ingredients instead. Foods like beans, shrimp and chicken are high in lysine, an amino acid that has antiviral effects, which can also block arginine, another amino acid found in foods like chocolate and peanuts that has shown to increase the rate of the herpes virus. Lysine and arginine work against each other, so be mindful of what you consume to maintain smooth and healthy lips. 

Skin Protection

Always wear sunscreen with a high SPF to protect yourself from harmful UV rays that can cause sunburns. Sunburns can affect your sleep and overall skin health, which can activate the herpes simplex virus. While a hydrating lip balm with SPF is an excellent way to protect your lips, it’s also important to wear sunscreen on your face and any exposed parts of your body all year round to help strengthen your immune system.
