now they will be focusing on my acne instead of talking to me.
Look around you and see all the normal looking and even unattractive men with good looking female partners.
I am only so so looking and with a speech defect and I had have some amazing looking ladies in my life and more important then looks outstanding women in every way.
Your problem is not that women are looking at your acne scares but that you are too aware of those scares when interacting with them to act in a manner that would result in them forming relationships with you.
To sum up you are being your own worst enemy when it come to women as everyone have some kind of scares/shortcoming it just that most of us do not focus on those scares.
