The excimer laser was invented in the 70s and uses a combination of two gases and electrical stimulation to create a laser light in the UV range. Currently, the most widespread therapy for the repigmentation of vitiligo spots  relies on narrow band UV radiation with a wavelength of 311nM (nbUVB), emitted  by a medical light bulb. This light can also be produced using excimer technology, with the advantage of laser’s precision, controlled dosage and good response from the skin.

Following the large interest triggered by the first stem cell article, we are now able to provide an update from the researchers at the Royan Institute in Iran. Dr. Nasser Aghdami, the head of regenerative medicine department has been king enough to answer some of our questions.

Based on evidence that oxidative stress is involved in the pathogenesis of vitiligo, it appears that antioxidant supplements are helping vitiligo patients regain pigment.

A study performed by researchers in Iran concluded that nbUVB vitiligo treatments are more successful when asociated with topical immunomodulators (Elidel, Protopic).

Many of the known treatments for vitiligo rely on daily ointment applications. But do we know how to properly apply the ointment and in what quantity ? Here are some guidelines on how much ointment to apply to your vitiligo spots.
