In a digital world, those with the strongest online profile pictures will survive. Of course, everyone else will probably survive, too; they just won’t look as sexy on Facebook.

With that in mind, Dr. Jeffrey Spiegel figured it was time to give people the lowdown on how to spruce up their Facebook pictures. As chief of Facial Plastic and Reconstructive Surgery at the Boston University School of Medicine, Dr. Spiegel is an expert in the art of making people look good (by any means necessary). Fortunately, you don’t have to go under the knife to kick up your online sex appeal and make all the internet honeys go weak at the cyber-knees. It’s just a matter of finding the right angle, sticking out your chin and keeping your eyes open long enough for the shutter to catch your good side.

Sound manageable? Here are Dr. Spiegel’s tips on how guys can look their best in Facebook photos:

1. Slightly protrude your chin.
This creates a strong face and eliminates a double chin. At the same time, slightly lean your neck toward the camera.

2. Stand at an angle to the camera.
This creates a slimmer body profile, and adds some interest to the photograph. Also, try lowering your shoulder toward the camera. This will relatively elongate your neck and slim it out.

3. Blink just before the camera goes off.
That is, if they are counting to three to shoot, blink deliberately on two. This will help guarantee that your eyes are not closed during the picture, and more importantly, will get you with the most open and bright eyes — and remember, bright eyes are critical to looking good.

4. Smile with your eyes.
A fake smile is just your mouth. A true smile is when your whole face is laughing. Think about sending energy to your eyes or smiling with your eyes.

5. Keep the lighting in mind.
If you have bad skin that you want to hide, position yourself so the light is coming directly toward you. Any blemishes should be washed out in the light. If you’re trying to accentuate your skin (because you have the good fortune of being clear-faced) then go for side-lighting.

6. Favor natural lighting when possible.
Natural lighting always photographs better than artificial lighting. If you’re inside, try to stand near a window when being photographed.
