Injecting near the psoriasis any benefits ?

I don’t think it would make a difference. Or maybe it does, but even contraproductive.
The injections with the bio, are aiming at the cells in your body. All cells, as it is not possible to go for specific cells. In that cells e.g. consentyx blocks Il-17, which in its turn reduces the activity of the cell in your arthritis or your Psoriasis.
The Psoriasis, the increased cell replication, gets to a hold from the inside, as it is only a representant of the immune disease you have which is everywhere in your body.

If you inject it, subcutaneous into a Psoriasis spot, it might get stuck more or less in the dead tissue that Psoriasis is and it might not spread effectively to your cells.

No I wouldn't inject into the psoriasis, that is a big  No No  

As a point of interest you inject in your groin with your treatment I wonder why that is the chosen route ?

@Jim thank you.

The reason for that location is that the now visible DNA that is in the blood has to be taken to the production center of the T-helper cells. That is to be done by the lymphe system.
There is a concentration of lymphe access buttons under your arms and in your groin.
Injecting under your arm is bit more risk full as there are large veins also under your arm, in you groin also, but over there they are much deeper and that is much more space to just go under the skin.

Basically you can give the injections everywhere, but in the end, to start working it has to access the lymph system. If you would inject it in your belly for instance, then it would take much much longer to reach the lymphe system. Then even the muscle would be a better place as more blood runs though that, or subcutaneous close to a muscle in a non-fat area.
