Avoiding Chicken Pox Scars

Chicken pox is a common childhood illness that most people recover from without any lasting marks. The blisters fill with fluid, crust over, and within a couple of weeks the whole thing is done. Scarring can occur in some cases, and these marks may be permanent. With proper management, including avoiding scratching, preventing infection and keeping symptoms under control, it is possible to reduce the risk of lasting skin damage.

Why chicken pox sometimes leaves scars

Chicken pox is caused by the varicella-zoster virus. It produces a rash of small blisters, typically less than a centimetre wide, that fill with fluid before bursting and forming crusts. In most cases, these heal completely without leaving any trace.

Scars tend to form when something disrupts the natural healing process. The main culprit is scratching. When a blister is scratched open, it can damage the deeper layers of skin and introduce bacteria, leading to infection. An infected spot takes longer to heal and is far more likely to leave a permanent mark.

The severity of the infection matters too. A mild case with only a few dozen spots is less likely to cause problems than a heavy outbreak covering large areas of skin. People with weakened immune systems, or those who develop complications, may be at greater risk of scarring.

Location plays a role as well. Spots on the face and chest tend to scar more noticeably than those on arms or legs. The skin in these areas is more delicate, and any marks that do form are more visible.

Keeping the itch under control

The itching is often the worst part of chicken pox, especially for children. It can be intense enough to make scratching feel unavoidable, so anything that reduces the urge will help prevent damage to the skin.

Calamine lotion is a traditional remedy that some people find soothing, though results vary and it does not work for everyone. It cools the skin and may take the edge off the itching. Apply it directly to the spots and let it dry, reapplying as needed throughout the day.

Cool baths can also help. Lukewarm or slightly cool water is gentler on irritated skin than hot water. Some people add colloidal oatmeal to the bath, which can have a calming effect. Pat the skin dry afterwards rather than rubbing, which can aggravate the spots.

Antihistamines may reduce itching, particularly at night when scratching during sleep is a risk. Chlorphenamine is available over the counter and is sometimes used for chicken pox in children. Consult a pharmacist or GP for appropriate dosages based on age, as recommendations vary. Non-drowsy antihistamines tend to be less effective for this purpose.

Keeping fingernails short and clean reduces the damage if scratching does happen. For young children, cotton mittens or socks over the hands at night can help. Loose, soft clothing made from natural fibres like cotton is more comfortable than tight or synthetic fabrics.

Preventing infection and managing symptoms

Bacterial infection is the main cause of scarring, so keeping the spots clean matters. Wash gently with mild soap and water. There is no need for antiseptic products unless a doctor recommends them.

Watch for signs that a spot has become infected. These include:

  • Increased redness spreading around the spot
  • Swelling or warmth in the area
  • Pus or yellow discharge
  • The spot becoming more painful rather than just itchy
  • A fever that returns after initially settling

If you notice any of these, contact your GP or call NHS 111. Infected spots may need antibiotic treatment. Caught early, this can prevent the infection from causing lasting damage to the skin.

Try not to pick at scabs as they form. It is tempting once the crusts start to lift at the edges, but pulling them off too soon can reopen the wound and increase the chance of scarring. Let them fall off naturally.

Chicken pox often comes with a fever, headache and general achiness, particularly in the first few days. Paracetamol can help bring the temperature down and ease discomfort. Follow the dosage instructions for the person's age and weight.

Some healthcare professionals advise against using ibuprofen for chicken pox, as some evidence links it to more severe skin complications. It is best avoided unless a doctor specifically recommends it.

Keeping fluid intake up is sensible, especially if there is a fever. Water, diluted squash and ice lollies are all fine. If the person has spots in their mouth or throat, soft cold foods may be easier to manage than anything hot or acidic.

Children can find the experience of chicken pox frustrating and upsetting, particularly when they cannot stop themselves from scratching or when they feel unwell for days at a time. Distraction helps. Films, audiobooks, gentle games and extra attention can make the days pass more easily.

The chicken pox vaccine

The chicken pox vaccine is not part of the routine NHS childhood vaccination schedule in the UK. However, it is available privately and some parents choose to have their children vaccinated to avoid the illness altogether.

The vaccine is around 90 percent effective at preventing infection, and even more effective at preventing severe disease. Some vaccinated people do still catch chicken pox, but they typically have a much milder case with fewer spots and less severe symptoms. This in turn means less itching, less scratching, and a lower risk of scarring.

If you are interested in the vaccine, speak to your GP. Some practices offer it or can refer you to a travel clinic or private provider. The cost varies but is usually somewhere between £60 and £150 for the full course, which requires two doses. Prices change, so check with the provider directly.

The vaccine may also be offered on the NHS to certain groups, including people who are not immune and are in close contact with someone who has a weakened immune system. Your GP can advise whether this applies to you.

If scars do form

Despite careful management, some people do end up with chicken pox scars. Many of these fade significantly over time, especially in children whose skin heals and regenerates quickly. A scar that looks quite noticeable after a few months may be barely visible after a year or two.

For scars that remain prominent, there are treatment options worth considering. Silicone gel sheets and creams are available over the counter and may help flatten and soften raised scars. They work best when used consistently over several months.

More stubborn scars can sometimes be improved with professional treatments such as laser therapy, microneedling or chemical peels. These are not usually available on the NHS for cosmetic reasons, but a GP can refer you to a dermatologist if the scarring is causing significant distress. Private treatment is an option for those who can afford it.

Sun protection helps too. Scars can darken with sun exposure, making them more visible. Using sunscreen of at least SPF 30 on scarred areas, particularly on the face, can prevent this.

Most chicken pox scars are small and fade to the point where they are barely noticeable. For the majority of people, they become a minor cosmetic issue rather than a serious concern. Taking care during the illness itself remains the best way to reduce the chances of lasting marks.
