Sensitive skin. Acne scar removal cream.

I am having sensitive skin that reacts to almost all products. Initially it was not the same. I have used garner light white complete for 10 years n never faced any skin problem. But now currently I frequent get acne n dry skin patches n irritation under eyes. I feel no cream is suiting me. Currently I am using minos S salicylic acid face wash and cetaphil lotion and sun stop 19 sunscreen. It almost suited my skin for 2 months but again it's the same issue. Sometimes my skin gets sensitive, sometimes dry, sometimes oily. I Hv tried almost all medicated sunscreens. Really fed up now. Also now I Hv some acne scars n white heads. Please suggest a good sunscreen lotion .Also suggest a mild under eye cream and also one acne scar removal cream .
