He has been having Pityriasis alba on his face for more than two years. We use good creams to moisturise the spots and I have also bought a high factor sun protection cream. It is written it should last for a few months and then disappear. The patches look like raised sand paper circles. Very tiny little rough pin like spikes. The patches are lighter than the rest of the skin.
No idea what to treat with to get rid of it.
Thank you.
