Yes, acne will effect a chick's opinion of you, but it depends on how severe it is. Because I've had it, I know what it feels like not being able to control your appearance. If you'd like, send me a pm and I'll tell you how I got rid of mine, it's not a cure but it WILL make them go away so long as you keep up the regimen, which doesn't involve taking risky meds or washing your face a million times a day. I've been to dermatologists and nothing they've ever prescribed me has worked to any significant degree. That's what makes acne so irritating, if you could simply get rid of it by going to a dermatologist no one would be complaining.
Seriously, I've had acne since I was 16 and I've finally found something that works after researching and experimenting for a very long time. It's actually not difficult to find info on what I've been doing but I won't post it here because people will start arguing over what they think works and yada yada yada...
