Talk to Dermatologist on White Spot On Face

Hi. . I have a question for a dermatologist, I used to suffer from Moderate acne last year I decided to go for Accutane 20-30-50-60MG for 7 months. Now don't get me wrong it worked 85% which is great but I have two Hypopigmentations one exactly in the middle of my forehead, it's barely visible but I can see it. The other one is on my right cheek. These marks white discolored patches about <.5 inch in diameter, slightly raised and yeah that is it. No itch no redness they don't tan away nothing. I actually did visit a supposedly top derma in ISB and was VERY VERY unhappy with her diagnosis she prescribed me some 'Gora huna wali creams which was pretty cliche thing to do' even though I specifically mentioned I am happy with my 'rung' I need help with my skin texture and tone etc. Please advice. Also I have tried anti fungal etc Didn't do anything. It's not vitiligo Been there for around 15 months now
