What are lip fillers?

Lip fillers involve injecting hyaluronic acid (HA) into the lips to fill out and reshape them aesthetically as desired. Fillers have the property of retaining water, making the lips appear moisturized and fuller. Lip filler injections can effectively correct thin lips, dry lips, drooping corners of the mouth, or unbalanced lip shapes. Furthermore, the results are visible immediately after injection, and it requires no surgery or downtime.

Lip filler injections following the Golden Ratio are a method that helps create beautifully shaped and natural-looking lips that harmonize with the facial structure. This involves determining the optimal proportions between the upper and lower lips as follows:

• The proportions of the upper and lower lips should be balanced in size and shape, with the lower lip being thicker than the upper lip in a ratio of 1:1.6 – 1.8, which is considered an aesthetically pleasing and ideal ratio.
• Upper lip groove (Philtrum) It should have a balanced curve, an M-shaped design with clearly defined indentations to add dimension to the lips.
• Lips  (Vermillion Border) has...Clear and proportionate on both the left and right sides.

• When viewed from the side, the lower lip should touch the line drawn from the tip of the nose down to the chin, while the upper lip should be approximately 2 millimeters away from this line.
• The width of the lips should be in proportion to the width of the face; generally, it should be about one-third the width of the face.
• The lower lip should not be too large, extending beyond the M-shaped border of the upper lip.

Ideal lip shape according to facial features (physiognomy).

According to the principles of physiognomy, or "Zhui Sai," it is believed that good lip shape can enhance various aspects of one's fortune, including relationships, career, and even luck, depending on individual beliefs. Generally, a good lip shape according to physiognomy should have a standard size, measured from the center of the eyes to the corners of the mouth. If the width is equal to the distance between the centers of the two eyes, it is considered good physiognomy. The lips should also have a clear shape, sharp edges, a slight indentation, and slightly upturned corners. Furthermore, the lips should have a healthy, rosy color, and should not be dry, cracked, or dark.

According to the principles of physiognomy, good lip shape enhances facial charm, boosts confidence in communication and negotiation, and leads to better interactions with others. However, physiognomy is a complex science and doesn't solely depend on lip shape; it also considers other facial features such as eyes, forehead, nose, and chin, as well as an individual's astrological chart.
