Radiation therapy and your skin

When you are going through radiation treatment, beams of radiation travel through your skin on their way to the affected area. Small amounts of radiation are absorbed into the skin during each treatment, which can lead to redness and irritation on the skin’s surface, similar to sunburn 1. This effect is called radiation dermatitis, and symptoms can also include dryness, itchiness, or soreness 2. Examine your skin regularly and keep your doctor up to date on its condition.

  • Cavilon No String Barrier Film

    3M™ Cavilon™ No Sting Barrier Film is Here to Help You Support Your Skin’s Integrity

    3M™ Cavilon™ No Sting Barrier Film is the only barrier film clinically proven to be effective in helping to manage your skin’s integrity during radiation therapy. Its sting-free formula forms a transparent barrier over the skin that helps protect your skin from friction and aids in moisture management. The effects of radiation therapy on your skin may not appear right away, but Cavilon™ No Sting Barrier Film can help to delay or reduce radiation skin damage without irritating the already-sensitive area. Help keep your skin safe and protect it by using Cavilon™ No Sting Barrier Film before radiation therapy begins.

    Be sure to consult your radiation doctor before use.

How to use 3M™ Cavilon™ No Sting Barrier Film

  • Cavilon Step 1

    Before using 3M™ Cavilon™ No Sting Barrier Film, gently wash your skin to take off any creams, lotions, gels, or any other products. Use a gentle, colourless, scent-free soap that is pH balanced. For best results, use Cavilon™ Skin Cleansers, which are designed to be extra-gentle and residue-free. Make sure the soap washes off fully and doesn’t leave a moisturizer behind, and then gently pat your skin dry.

  • Cavilon Step 2

    Cavilon™ No Sting Barrier Film should only be applied where no ignition sources or heat-producing devices are in use. Avoid using around flames, and do not smoke while applying the film.

    Hold the bottle of Cavilon™ No Sting Barrier Film 10-15 cm from your skin, and spray onto the areas that will be affected. Each spray will cover an area of 8-10 cm. Repeat until the entire affected area has been covered with barrier film, and then allow the film to dry completely, which takes about 30 seconds. Be careful not to spray the film in your eyes, nose, or mouth.

    If you are spraying the barrier film onto an area within a skin fold (for example, underneath your breast), hold the skin apart until barrier film is completely dry, about 30 seconds.

  • Cavilon Step 3

    Reapply two times per week. For example: Monday and Thursday, Tuesday and Friday, or Wednesday and Saturday could be your application days. If used in the perineal area with diarrhea, apply every 24 hours to help prevent skin break down from increased bowel movements.

  • Cavilon Step 4

    Washing off the Cavilon™ No Sting Barrier Film is not necessary before your next use. Sometimes the barrier film may build up and look like flaky skin, but this is normal, and will not harm you.

  • Cavilon Step 5

    Make sure you don’t use any ointments, creams, lotions, or gels under or over Cavilon™ No Sting Barrier Film. These products are unnecessary and may cause problems with how the barrier film product works.
