In recent years, home-use 308nm excimer phototherapy devices have become increasingly popular among individuals with vitiligo due to their multiple advantages, such as "stable light output with a single wavelength," "easy to operate," and "achieving comparable results to hospital-based phototherapy at home." So, which patients are more suitable for home 308nm phototherapy?

In recent years, home-use 308nm excimer phototherapy devices have become increasingly popular among individuals with vitiligo due to their multiple advantages, such as "stable light output with a single wavelength," "easy to operate," and "achieving comparable results to hospital-based phototherapy at home." So, which patients are more suitable for home 308nm phototherapy?

1、Condition in the Stable Stage

The criteria for determining vitiligo's stable stage typically include: no spread of white patches for over six months, clearly defined borders with stable coloration, and no new lesions. Due to significant individual differences, it is best to have a doctor comprehensively assess whether the condition is in the stable stage.

The stable stage is a critical treatment window. At this stage, the destruction of melanocytes in white patches halts, and clearly bordered white patches may still retain a small number of melanocytes, making phototherapy more likely to promote repigmentation. Additionally, patients in the stable stage have better disease controllability, and timely intervention can reduce the probability of future recurrence.

2、Full Understanding of Phototherapy Dosage Adjustment Methods

The dosage for vitiligo phototherapy should be personalized based on the patient's skin type, phototherapy device, and individual response. The initial dose is typically low, followed by gradual increases based on the skin's reaction to the treatment.

It is crucial for vitiligo patients to know the light output intensity of their home-use 308nm phototherapy device, as this directly relates to the dosage for each session. If multiple areas have white patches, different dosages may need to be set for each.

3、Prior Experience with Hospital Phototherapy and Understanding of Precautions

Patients who have undergone phototherapy in hospitals possess some experience with the treatment. As mentioned earlier, before hospital-based phototherapy, patients typically sign documents similar to a "308nm Excimer Laser Treatment Informed Consent Form," which provides a systematic introduction to the treatment, course duration, potential outcomes, and explanations, helping individuals with vitiligo gain a comprehensive understanding of 308nm phototherapy.

Therefore, patients with prior hospital phototherapy experience tend to approach the treatment more rationally and calmly. This reduces insecurity about phototherapy and improves adherence.

If using 308nm phototherapy at home, it is essential to do so under the guidance of a professional. Additionally, consistency is key—avoid irregular or sporadic treatment sessions.
