Psoriasis skin confusion

[Fred]

Now, my question is... when i run my finger over it, I noticed that the skin feels ever so slightly more raised, rougher and dryer, oppose to the other side under my other eye where its softer, smoother etc. 

Can someone enlighten me as to what this may be? Is it psoriasis coming back (despite no burning or itching sensation). Is this how the skin heals? is it just dry left over skin because it's thinner? Will it return to it's normal smoothness so I can apply concealer again? 

Difficult to answer. It would be best to check with your dermatologist
