Are you chasing a sexy, lifted, Western-style butt? Is the smile line really the key to a great butt shape? What exactly is the “smile line,” and what line proportions add to the buttocks? This article introduces the benefits and golden ratio of the smile line, and shows how liposuction and filling can help create a natural, attractive peach butt!

What Is the Butt Smile Line?

The butt smile line, also called the gluteal line or buttock crease, is located at the lowest part of each buttock, where it meets the thigh. When the gluteal muscles are firm, full, and elastic, the downward pull of muscle and fat forms a distinct rounded curve. Because the two ends of the line curve slightly upward and are symmetrical, it looks like a smile and is named for it.The smile line supports the underside of the buttocks and prevents sagging. So besides being attractive, it is the pillar of the buttocks and should not be altered carelessly so that it recedes, which would cause the buttocks to sag.

Benefits of the Smile Line

1. Adds dimension to the buttocks

2. Lengthens the proportions of the butt-to-leg line

The Golden Ratio of the Smile Line

1. At rest, seen from behind, the smile line should not be longer than 1/2 to 2/3 of the width of the back of the thigh

2. When walking, the smile line should lengthen and shorten as the thigh extends and flexes

Ideal Waist-to-Hip Ratio and Butt Shape Features

Seen from the side, the ideal waist-to-hip ratio is about 0.7-0.75. Most Asians tend to prefer a more refined, conservative ratio (around 0.75), while Westerners pursue a more prominent butt curve (0.7-0.725), with the preferred highest point at the very center of the buttocks.

4 Main Reasons the Smile Line Disappears

If the smile line is very low, or barely noticeable and almost gone, the buttocks have already loosened and sagged! The following four points may cause the smile line to disappear:

1. Excess fat weighing down the buttocks

2. Aging laxity / collagen loss

3. Loosened, atrophied gluteal muscles

4. Changes in buttock tissue after childbirth

To improve poorly defined buttock lines, the only effective and direct ways are exercise and aesthetic surgery. Exercise trains the muscles from the buttocks to the thighs and is effective for lifting the butt, but when deep fat accumulates in the buttocks, it is sometimes difficult to eliminate through exercise. At that point, aesthetic treatments can help sculpt the butt shape, adding fullness to the upper buttocks and reducing sagging in the lower buttocks.

Sculpting the Smile Line: Removing Excess Fat

With VASER liposuction, the smile line can be sculpted, and fat-prone areas such as saddlebags and the inner and outer thighs can be liposuctioned at the same time. The buttocks and legs are treated as one whole unit to shorten the prominent points of the butt line and raise the smile line, lengthening the leg line and making the buttocks look smaller.

Creating a Lifted Butt Curve: Fat Transfer Butt Augmentation

Most Asian women naturally lack fat in the buttocks when viewed from the side, so they tend to have a flat butt. After excess fat is removed from the buttocks, the principle is the same as fat transfer breast augmentation: your own fat can be used to fill the hollow areas of the buttocks to create a fuller look.
