Please help me!(dry skin)

Here is my story. Sorry about my bad english.
I took finasteride for year and a half and then i used dutasteride for about 6 month. When i was taking those pills i got severe acne on my face and my back, and my body hair is almost disappeared and i got diffuse hairloss too. I think it is due to severely dry skin. So now i am off the drug for 14 month and severly dry skin is not getting better. I am having really hard time. It seems like there is no more sebum producing in my body. Has anyone recovered from these symptoms? Please help me!! My life is totally ruined. I feel like dry dead body. And my face is totally ruined.
