How do you get vitiligo?
The cause and pathogenesis of vitiligo is still not very clear, generally speaking and genetic, neuropsychological factors, melanocyte self-destruction, immunity, cytokines and other factors related. The actual fact is that you can find a lot of people who have been in the business for a long time, and they are more likely to get vitiligo from sun exposure and trauma. How to determine whether the white spot is vitiligo?
The actual fact is that you can find a lot of people who are not able to get a good deal of money from the internet. The typical manifestation is a round, oval or irregular-shaped white rash with distinct boundaries, which may be surrounded by a slightly darker pigmented band at the edges, and there may be islands of normal skin color in the white spots, and the hair on them may also turn white. After rubbing, the white spots become congested and red. At present, our newly introduced skin confocal microscopy – skin CT examination is more beneficial to confirm the diagnosis. This examination is non-invasive and can directly observe the pigment content and melanocyte situation in the white spot area, and also determine whether it is in the progressive stage, and even observe the treatment effect.
What are the methods of treating vitiligo?
The current treatment methods mainly include systemic, local hormone treatment, immunomodulator treatment, surgical treatment and Chinese medicine treatment, among which physical optical therapy is one of the most effective and safe treatment methods, especially the 308 nm excimer laser has the most significant effect.
What is the treatment principle of 308 nm excimer laser?
The 308 nm excimer laser is a new type of light source with a single wavelength, higher efficacy and better efficacy than ordinary narrow ultraviolet light (NB-UVB). It can stimulate melanocyte proliferation and promote melanin production; induce T-cell death; and promote vitamin D3 production. It is easy and fast to treat, short course of treatment, fast results, safe and reliable, and is one of the most effective methods to treat vitiligo and psoriasis.
Why is the 308nm excimer laser better than the ordinary narrow ultraviolet light (NB-UVB)?
1, wavelength more single: 308nm excimer laser wavelength single, increase its treatment effectiveness, reduce the side effects.
2, fast treatment: the treatment time is 5 to 90 seconds, convenient and fast, even for patients with large lesions, it only takes 2-3 minutes, greatly reducing the inconvenience to patients’ daily life and work.
3, high efficiency: good treatment effect, optical effect is obvious.
4, safety: side effects are very small, because there is no invalid harmful light, so the treatment is safer.
5, no recurrence: current research shows that the recurrence rate of 308nm excimer laser treatment is zero, and the efficacy is reliable.
What is the treatment plan of 308nm excimer laser?
Two times a week at an interval of 2 to 3 days, usually about 10 times to see results. Our clinic is currently open on Tuesdays, Fridays and Saturdays. Patients feel no sensation or a warm sensation during treatment, and small lesions are treated in seconds to minutes. It is suitable for patients of all ages, including children with vitiligo, but not for systemic treatment, as the spot size of this device is only 2×2cm2.
What is the long-term efficacy of the 308nm excimer laser?
Excimer laser treatment for vitiligo has long term effects once the color is regained. To date, there have been no reported cases of recurrence in excimer laser treatment of vitiligo worldwide. The same is true for psoriasis where a follow-up study in 2003 reported remission of psoriasis with excimer laser treatment for more than 3 years (without further treatment).
Is the 308nm excimer laser safe and can it damage my skin?
The 308nm excimer laser is very safe for the treatment of skin conditions. It is FDA and SFDA approved and has not been reported to have any adverse effects, not to mention the risk of cancer. Its square spot avoids laser exposure to normal tissue, minimizing damage to normal skin.
What are the side effects of the 308nm excimer laser?
Side effects are minimal, with only a slight burning sensation at the irradiated area during treatment, and some patients may feel a little pain in the affected area for a few hours after treatment (similar to a mild sunburn). For patients with psoriasis, there may be some erythema, or a short period of postoperative hyperpigmentation (usually recovering on its own within 3 months to 6 months). There are few side effects in patients with vitiligo, with occasional minor blistering due to increased energy. Even if blisters do occur, they are kept dry and absorbed naturally without scarring.
Can the 308nm excimer laser be used on infants The excimer laser can be safely used on people of all ages from infants to the elderly.
