Chin
Beauty is not an exact science but according to some Plastic Surgeons there is a specific proportion system that the "ideal" face has. With regards to the “ideal” chin formula, if you take a photo of yourself (from the side) and draw a line from the most prominent part of the brow (between the eyebrows) to your chin it should be a vertical line.
If this confirms your suspicions that you chin is ‘weak’ or under developed then chin augmentation with soft tissue dermal fillers or subdermal fillers may help to strengthen the appearance of a receding chin and restore balance to you face.
Just remember, if you don't "pass" the “ideal” chin test -- don't take it to heart. No one is truly symmetrical. Remember that beauty is also about attitude, so make it a good one!
