1. Preparations Before Phototherapy

·Clean the affected skin to ensure the treatment area is clean and free of oil, cosmetics, or other residues

· Locate the affected areas accurately. Use an appropriate light - emitting port or a cut - out light shield to target the leukoplakia. For irregularly - shaped leukoplakia or hard - to - fix parts, you can cut holes in old, unused clothes and so on. Do your best to shield the skin that does not need to be exposed to the light.

· Wear protective goggles to safeguard your eyes. If there is leukoplakia around the eyes, you need to wear protective eye masks. If you need family members to assist with the phototherapy, they should also wear protective goggles at the same time.

2. Tips During Phototherapy

· At the initial stage of phototherapy, the dosage must be set under the guidance of professionals. Start with a low dose and gradually increase it until you find the optimal dosage for the affected areas.

· Record the phototherapy dosage and the post - treatment reactions for each different affected area every time. This will facilitate observation and timely dosage adjustment. Set the parameters of the phototherapy device in units (dosage or time) that are easy for you to remember to avoid incorrect dosages caused by memory lapses.

· During phototherapy, make sure the light - emitting port is as close to the skin as possible. Check irregularly whether the shields have shifted or loosened, and adjust them promptly to prevent accidental exposure of normal skin.

· For large - area leukoplakia, divide the irradiation area into several parts and perform phototherapy in batches. Try to avoid overlapping the irradiation areas of each part; otherwise, it is easy to cause excessive irradiation in the overlapping regions.

· During phototherapy, adjust the angle and position of the phototherapy device according to the specific conditions of the affected areas on different parts of the body to ensure the phototherapy effect.

3. Post - Phototherapy Care

·Avoid immediate contact with water. Refrain from getting the treated skin wet within 2 to 6 hours after phototherapy to allow sufficient time for the skin to absorb the light.

· Skin care treatment: If symptoms such as dryness and itching occur, avoid pressing, rubbing, or scratching the skin. You can use mild and non - irritating moisturizing creams or aloe vera gel to help the skin replenish moisture and alleviate the symptoms.

·Pay attention to sun protection: The skin will become more sensitive after phototherapy and is extremely vulnerable to ultraviolet (UV) damage. Try to avoid going out when the sun is strong. If you have to go out, make sure to take adequate sun protection measures.

· Observe the reactions: Generally, check the affected areas after 24 hours to see if there are reactions such as redness, or if adverse reactions like swelling and blistering have occurred due to the dosage adjustment of this phototherapy session. If such situations happen, contact professionals for further measures.
