Light skin Indian, would benoquin for 1 month depigment my facial skin?

I am a light skin Indian. My face is the darkest part (Fitzpatrick 4 ) whereas my hands, arms, body etc are Fitzpatrick 1-2 shade. I have tried vit c, arbutin and even HQ with lasers with no change. Would benoquin for 1 month work? I just want to match my face to the rest of myself. would it be limited to just my face as I read it works through immune system thus unpredictable. thanks.
