Skin, Hair and Nail Problems

So I have pigmentation above my upper lip area (where we get threading done) It's not because of any medicine and all. Maybe because  of hair removal methods have caused this. Is there any ointment which will cure the pigmentation, we do also have pigmentation on under arms (women do have as far as I know.) So what is the best solution and is it curable completely in a inexpensive way or not. And also what is the best way to remove upper lip hair as I don't visit parlours specially after COVID.

I have hyperpigmentation on my upper arms from last 1 2 years and it's getting darker with time . A dermatologist recommended me these products to use twice a day ( I am using these from last 3 weeks) 3. Ilumax skin brightening cream . 2.Epilite 5 % hydroquinone solution. 1.Percos clobestasol propionate and salicyclid acid lotion (1,2,3 is order of application) But after using these twice my skin has become irritated & dry . Please let me know if will these products be effective ? Or should I stop using these as I have heard that topical treatments aren't effective for curing hyperpigmentation and you have to undergo laser treatments for the same .
