Frequently Asked Questions



Call the Photocil Session Service (PSS) at 1-844-4SESSION each time you want to begin a treatment session with Photocil.

This free service helps you to start your treatment at a time that the sun’s UV is within a calculated range to receive the necessary therapeutic UVB radiation for your phototherapy. It also calculates the exact amount of time you will remain in the sun from the time of your call so you don’t receive too much or too little UVB radiation for your skin type. When you call into the PSS it will calculate your time based on your doctor’s prescription.

It is important to remember that you must remain in direct daylight until the PSS calls you back to indicate the end of your session. Following this procedure each time will insure proper light exposure.

There are two reasons why the PSS may not recognize you, they are:

1. You have not yet registered to use the Photocil Session System. Registration is easy. Please click here to register.

2. You are calling from a phone number that you did not register with PSS during your original registration process. If this is the case, you can either call from one of your registered numbers or add a the new number you would like to use to your list of numbers. You can add an additional number by clicking here.

If neither of these options apply to you, please call customer service at 1-844-APPLIED for further assistance.

To conduct a Photocil treatment read the following or view the Photocil visual guide here:

1. Make sure you have enough time to complete a full treatment. To insure the shortest treatment time possible, conduct your treatment as close to midday as possible.

2. Check outside to make sure that weather conditions are clear (sunny).

3. Apply Photocil treatment cream topically to the affected areas that require phototherapy treatment.

4. Protect non-affected skin that will be exposed to daylight with clothing, hat, and/or sunscreen. Never cover the Photocil treated areas with sunscreen or cover with clothing. If your affected areas are treated with sunscreen or covered, they will not receive therapy.

5. Proceed outdoors and call the Photocil Session System at 1-844-4SESSION.

6. Make sure that you will be able to immediately start and complete the recommended treatment time before agreeing to start the session. If the session time seems too long, try to plan your next session closer to 12 o’clock noon.

7. Keep all lesions or affected areas in direct daylight for the entire duration of the treatment time.

8. When your session is complete, Photocil’s Session System (PSS) will call and notify you that your treatment session is complete. End treatment by covering lesions or affected areas and going indoors.

Photocil treatment cream is designed to work with natural outdoor daylight. Photocil should only be applied immediately before your planned treatment session.

No. Applying Photocil alone, without daylight, will not provide therapeutic benefit. Photocil is activated only by direct daylight.

Photocil treatment sessions work best when there is the most daylight. This will typically occur in late spring and summer months, however, at certain locations daylight is intense for more months of the year. Below are sample times for the Miami / Fort Lauderdale area by month.

Photocil is activated by daylight and will work best when the sun is brightest.

Daylight is most intense around 12 o’clock noon (or shortly before or after depending on your location), therefore midday start times are the best choice for good therapy. Also midday sessions will always be the shortest session choice for your treatment regimen.

Yes, starting treatment in the afternoon and morning are possible for certain locations and times of the year depending on your skin type. However, session lengths will typically be longer than sessions planned around 12 o’clock noon.

You will receive the most optimal times for treatment midday and during the months with the highest UV from the sun which are typically late spring and summer.

Length of time also depends on your skin type. Skin types range from 1-6. The higher skin type numbers typically require longer treatment times.

Sometimes high temperature doesn’t mean that daylight is strong. Heat is the result of infrared radiation, which is not therapeutic for psoriasis. The radiation that is therapeutic for psoriasis is strongest around 12 o’clock noon and decreases later in the day.

No. Photocil treatment sessions cannot be done indoors. Glass from windows filter out therapeutic radiation.

No. The Photocil Session System calculates the right treatment time for you with only one start time. It is important to remain in daylight for the entire treatment time until the PSS calls you back to end your session. This is because the intensity of daylight will change during the day and the session time calculated by the PSS at the time you call will not be accurate for a different time.

No. When you call into the Photocil Treatment System you should not select the option to start your treatment until you are ready to do the treatment immediately. Session times calculated by the PSS will not be accurate for a different time, even if it’s 20 minutes later.

You should not do another (make-up) session on the same day. You will need to wait until your next planned session day to do another treatment session.

For areas of your skin not requiring treatment, a 30 SPF sunscreen can be used with your Photocil treatment plan to provide protection. As with any routine sun exposure, there are associated risks (sunburn and increased incidence of cancer) so untreated areas should be protected. Clothing and hats are also good options to protect untreated skin.

No, Photocil cream is water soluble, therefore if you apply Photocil cream to an area and the area gets wet, you will need to thoroughly dry the area and reapply.

A cream style (lotion) sunscreen with a minimum 30 SPF is recommended for use when using Photocil on other areas of your skin. Choosing an easily controllable (not runny) sunscreen will ensure that your affected areas are not unintentionally treated with sunscreen.

Do not put sunscreen on the areas you wish to treat. If your affected skin areas are treated with sunscreen, they will not receive therapy. Spray sunscreens may interfere with the areas applied with Photocil and are not recommended.

No. Spray sunscreens are not recommended because they are not easily controlled and can unintentionally cover your affected areas. If your affected areas are treated with sunscreen, they will not receive therapy.
