How can I get rid of rough, bumpy skin on my face?

I switched cleansers for a couple of days, normally I use this organic milky cleanser because I have dry skin, but since I've used this other cleanser my skin is gross! my beauty routine consists of putting coconut oil on my body when i get out of the shower, putting coconut oil on my face after cleansing and patting it try and using cacao butter and a vitamin c cream.
I also drink heaps of water and have alot of fruit and veggies and find eating bread and pasta dries out my skin.
