Hello, is there a medical procedure or any fastest way to get rid of pityriasis versicolor? pls. im so devastated for 2years because its in my face

Yeast treatment: Pityriasis versicolor is caused by a yeast. Miconazole, ketoconazole and Clotrimazole can help get rid of the yeast. Discoloration may last months. Control the fungus. But try a soap/wash with 2% pyrithione zinc for 10 minutes daily before rinsing, then apply Lamisil (terbinafine) at spray or Miconazole to affected areas. Use oil free sunscreen. If better go into a maintenance plan. Or move to a cool climate.

Uncommon on face: Pv is uncommon on the face due to oil in skin but can happen - are you sure of diagnosis? If so, would use topical anti-fungal cream 2 x per day and apply selsun blue at bed and let dry overnight and wash off in am. If severe and doesn't respond to topicals then your family doc can prescribe oral antifungal - usually 1 pills a few days apart followed by exercise to sweat it "onto" skin works well.
