APPLYING AND CHANGING THE ARRAYS

Learn how to apply and remove your Optune Lua arrays.

Soon enough, changing your arrays will become part of your treatment routine.

Preparing your skin for array placement

Before placing the arrays, be sure that you:

Remove existing hair

You can use an electric shaver for a short trim. It does not need to be a close shave.

Wash your upper body

Use warm water, a washcloth, and hypoallergenic soap. You can take a full shower if you prefer.

Applying and changing your arrays

Follow the step-by-step guides below to learn how to apply and remove the Optune Lua arrays.

Make sure your care partner is available to help you, since it may be hard to place the arrays on your own. Follow the steps below:

Wash your skin with warm water, a washcloth, and hypoallergenic soap. You can take a full shower if you prefer. Gently pat your skin dry with an absorbent towel to remove moisture or residue.

Remove existing hair (if needed or at least every 7-10 days). You can use an electric shaver for a short trim. It does not need to be a close shave.

Let your skin breathe for up to a few hours (optional) and use a fragrance-free, water-based moisturizer. This can help reduce skin irritation.

Clean again. Remove any residue from the moisturizer before array placement. Apply any prescribed medications (if applicable) and let absorb for at least 15-20 minutes. Clean away any residue by gently cleaning the skin with water using a gauze pad or cloth. Avoid rubbing to minimize skin abrasion or damage.

Apply any skin barrier recommended by your doctor.

Make sure you have 4 total arrays, 2 with black connectors and 2 with white connectors. Remove the array liner from the first array. You may use the Array Applicator to help. Reach out to your Device Support Specialist if you have any questions.

Place the arrays, one at a time. Make sure to press the edges firmly onto your skin. When changing the arrays, place them 2 centimeters (0.75 inch) from the original position. Refer to the array layout map for placement instructions and see the Caring for Your Skin With Optune Lua brochure for tips and best practices.

Plug the array connectors into the connection box. Make sure the arrows on the connectors face the silver post. Line up the black and white arrays according to the color on the box. Then, plug the connection cable into the Optune Lua device and start treatment.

Wear your clothes as normal over the arrays. It is recommended to wear the arrays for at least 12 hours per day on average for the best response.

Being proactive about skin irritation

Contact your doctor if you experience swelling, redness, excessive itching, or other skin-related symptoms. Your doctor may prescribe prescription medication applied to the skin to treat skin irritation. You can help reduce your risk for developing skin irritation by changing your arrays at least twice per week, or every 4 days at most.
