Radiotherapy can cause the skin in the treatment area to become:
- red or pink
- dry or itchy
- darker in color
- warm or slightly tender
1. Keep the skin moisturized — but use doctor-approved products only
Moisturizing helps reduce dryness and redness, but not all products are safe for radiotherapy.
Safe options usually include:
- aloe vera gel (pure)
- water-based unscented moisturizers
- doctor-recommended creams
Avoid:
- oily or petroleum-based lotions
- perfumed products
- whitening lotions
- alcohol-based toners
2. Be gentle when washing
You may shower normally, but keep the treatment area gentle.
Do:
- use mild soap (baby soap or gentle cleansers)
- pat dry with a soft towel
- use lukewarm water
Avoid:
- scrubbing or rubbing
- hot water (can increase redness)
- loofahs or exfoliating tools
3. Protect the area from the sun
Treated skin is extra sensitive to sunlight. Even a short exposure can worsen irritation.
- avoid direct sun exposure
- use an umbrella outdoors
- do NOT apply sunscreen on the treatment area during the entire course
4. Wear soft, loose clothing
Tight clothing can rub against sensitive skin.
Use:
- cotton shirts
- loose bras or sports bras (for breast RT)
- soft fabrics
Avoid:
- tight straps
- rough fabrics
- underwire bras (if irritating)
5. Do not scratch or peel the skin
Even if it becomes itchy or flaky, avoid scratching.
If peeling occurs:
- inform your treatment team
- use recommended ointments
- keep the area clean and moisturized
6. Avoid heat exposure
Heat can worsen radiation skin reactions.
- avoid hot packs
- avoid placing the treatment area near stoves/ovens
- avoid heated massage devices
7. Do not apply unknown herbal oils or homemade mixtures
Some oils or herbal rubs can irritate the skin or interfere with treatment.
8. Keep markings intact
If your treatment uses skin markings (small dots or stickers), avoid washing or rubbing them off.
9. When to call your doctor
Inform your team if you notice:
- blistering
- open wounds
- severe redness
- increasing pain
- fever or signs of infection
