Why is it risky to touch the face although there is no direct contact with into the nose, eyes and mouth?

Is there any possibility that pathogens infect us from our facial skin?

Suppose we have viruses or bacteria on our hands and we touch the side of our nose with our hands.

Can these bacteria reach our noses by their own? 🤔
