What Is Granuloma Annulare?
8. Experimental Treatment
Three primary experimental treatments are currently in use for those with severe forms of GA. One approach, called PUVA, is to apply the drug psoralen to the affected area. Following application, an ultraviolet light is used to activate the drug. This has the potential to slow down the spread of the rash because the drug and UV combination inhibit skin cell growth.
Another experimental treatment utilized is cryotherapy. The impacted area is frozen in an effort to stave off further rash growth. Laser therapy might also be tried. With this treatment, a laser is used to direct heat to the affected area to reduce inflammation and slow the spread.
