Introduction
Cold sores always seem to show up at the worst possible time—right before a big event or when you’re feeling under the weather. These fluid-filled blisters, caused by the herpes simplex virus type 1 (HSV-1), can be painful and slow to heal. But with quick action and the right treatment, you can cut down the time they stick around and reduce discomfort dramatically.
Whether you're looking for a fast-acting pharmacy solution or a gentle, natural remedy, this guide explores the best cold sore treatments available in the UK so you can recover faster and feel more confident.
Why Do Cold Sores Keep Coming Back?
Once HSV-1 is in your system, it stays for life. It lies dormant in the nerves and can reactivate under certain conditions—usually when the immune system is under stress.
Cold sore triggers often include:
- Physical exhaustion or mental stress
- Fever, illness, or respiratory infections
- Hormonal fluctuations
- Harsh climates or excessive sun exposure
- Poor nutrition and lack of rest
Knowing your triggers allows you to stay a step ahead of outbreaks by treating early or even avoiding them altogether.
What Cold Sore Creams Are Designed to Do
Topical cold sore creams work by targeting the virus directly on the skin. Their goal is to either prevent the virus from multiplying or block its ability to affect surrounding cells.
Benefits of cold sore creams include:
- Speeds up the healing process
- Reduces the discomfort and swelling
- Limits the spread of the infection
- Helps reduce the chance of secondary skin issues
Creams work best when applied at the first sign of tingling, itching, or tightness around the lips.
