Dry Skin dullness and hyperpigmentation.

I've been having issues on my face skin . Major issue is dry skin. I have difficulty in choosing the products that suits me .I've always picked wrong ones and that has made my skin look even worse . I have pigmented face and lips . I have dandruff issues so when ever it's too itchy I get allergy on my hands and face it remains for 5min and disappears. Kindly help me choosing the right skin care routine and I wish to have a skin that glows .mine is soo very dull and dried up . I also have dark circles which make my skin look even worse . I have wasted a lot on products and ended up with only disappointment. I'm still not able to use my correct face wash moisturizer and sunscreen and any thing other after that. Kindly suggest me a good routine .
