Hi Dear,
Welcome to HCM team.
Understanding your concern.
As you mention in your query that you have white spots on your face which spreading .The most probable cause of these white spots is
fungal infection.There are certain factor which favor fungal infection like excessive exposure to sunlight .
excessive sweating ,ot and humid environment.The condition is known as
tinea versicolor.
I would suggest you to -:
-Protect your skin from sun exposure .
-Use anti fungal cream containing clotrimazol .apply it twice a day .
-wash your face twice a day with mild soap .
-Apply turmeric paste this will also be very helpful.
If symptoms persists for more then a week or get worse
consult dermatologist ,so that doctor can evaluate properly to rule out other conditions like vitiligo and may prescribe you
oral antifungal or topical steroids.
Hope your concern has been resolved.
