I have a dark pigmentation on my cheek bone

Nonacademic!
I have a dark pigmentation on my cheek bone. And now my dermatologist prescribed a steroid cream(HH LITE) I’m scared to use because it has mometasone. I clearly remember in college dermatologist told I’ll never use that cream because it has steroid. Now I’m confused and I’m not sure what to do.
Any dermatology residents pls opine if it’s okay to use it? Or will it reappear darker when stopped

Even my dermatologist recommended HH Lite for my tanned arms…using it for 10 days but no much result…going to consult her this weekend

nd earlier I’ve used mometasone for tan on my face…5 yrs back…no reappearance of tan marks 👍🏻👍🏻👍🏻

Better share ur doubts with ur dermatologist once
