Any suggestions for Skin lightening? (photos)

I have used aziderm 20% and adalpene for 3 mnths but improvement in skin lightening. Now I m using retina A Micro as prescribed by doc I just see peeling and skin more sensitive my skin is becoming darker now. I use Photostable sunscreen as my skin is oily. ( I don't wnt Any steroid cream or cnt afford laser n chemical peels). I would really appreciate if you can suggest night creams or gels without any side effects for skin lightening for long use. I am really fed up on spending money.
