Brief Answer:
most likely pityriasis versicolor

Detailed Answer:
Hello xxxxxxxxxx, Welcome to HCM,
I've gone through your query and understand your concern,

I've reviewed the image and it's most likely resembling Pityriasis versicolor, a superficial fungal infection caused by a yeast..

You need to go for Potassium hydroxide examination(KOH preperation) of the skin-scraping from the particular affected area under supervision of a Dermatologist. This is necessary to rule out the fungal infection as management depends on this (if fungal infection detected, a course of anti-fungal like oral Itraconaconazole along with topical application will be advised)..(if no infection detected then a short course of mild steroid ointment for 10 days should be tried )..

This should be done under strict supervision of a Dermatologist only..so please schedule the appointment and get the necessary investigations done at first..management will be according to the findings as explained..

Take Care
Kind Regards
