How effective is the 308 phototherapy device in treating white spots?

Generally, the 308 excimer light therapy device is effective in treating white patches (vitiligo) and can promote the recovery of depigmented areas. The detailed analysis is as follows:

White patches are usually caused by the loss of function of melanocytes in the skin and may be associated with factors such as genetic predisposition or autoimmune diseases. This condition leads to the appearance of white spots on the skin, commonly presenting as depigmented patches, localized itching, and other symptoms. The 308 excimer light therapy works by emitting a specific wavelength of light that stimulates melanocytes in the skin, thereby promoting melanin production and helping restore normal skin pigmentation. The typical reference cost for each 308 light therapy session ranges from 1,000 to 2,000 yuan. Improvement is generally observed within 2 to 8 weeks after treatment, although possible side effects may include skin burns, inflammation, or erythema (redness).

In current clinical practice, 308 nm excimer laser therapy is widely used for treating vitiligo. It is generally associated with a low recurrence rate, causes no significant toxic side effects, and involves minimal discomfort for patients. When combined with oral medications, this therapy can effectively control symptoms.

In daily life, it is important to take proper sun protection measures—wear sun-protective clothing or use umbrellas when outdoors to avoid prolonged exposure to ultraviolet radiation. Maintain a balanced diet by consuming more fresh fruits and vegetables such as apples, kiwifruit, and spinach, while minimizing spicy, stimulating, or greasy foods. Ensure adequate sleep and avoid staying up late.
