What Is Aesthetic Smile Design? Mouth Corner Lines and Thread Applications

Smile Aesthetics: Mouth Corner Lines and Thread Procedures

Smiling is one of the most natural expressions that reflects the vitality, warmth, and personality of a face. Over the years, frequent smiling, mimic movements, changes in skin elasticity, and volume loss can lead to more prominent nasolabial folds extending from the corners of the mouth towards the nose, shadows around the mouth, and a feeling of laxity in the cheek area.

These changes do not mean one should stop smiling. In aesthetic dermatology, the goal is not to eliminate facial expressions or make the face expressionless, but to consider facial anatomy and evaluate personalized options for a rested and balanced appearance that supports the smile line. Smile aesthetics is a part of this approach.

What does smile aesthetics mean?

Smile aesthetics is not an application focused solely on the lips or a single line. When smiling, the area around the mouth, cheeks, cheekbones, jawline, and eye area move together. Therefore, when evaluating changes in the lower and middle regions of the face, it is necessary to look at the overall balance of the face instead of trying to correct a single area.

The downward displacement of cheek tissue over time can contribute to the appearance of more shadowed lines at the corners of the mouth. Decreased skin elasticity can accentuate this appearance. For some individuals, the issue may be primarily superficial lines, while for others, slight tissue sagging or volume loss may be dominant. Accurate planning can only be made by identifying these differences during an examination.

Why do nasolabial folds become more prominent?

The nasolabial fold is a natural facial line that starts from the nasal wing and extends towards the corners of the mouth. It is present in everyone and contributes to facial expression. However, with the aging process, the deepening of the line or the formation of shadows around it can make an individual feel and appear more tired or sad than they are.

Multiple factors play a role in the formation of this appearance:

• Changes in collagen and elastin fibers that develop over time
• Volume loss in the cheek and mid-face area
• Relaxation of subcutaneous connective tissue
• Genetic predisposition and facial anatomy
• Extensive use of facial expressions
• Sun exposure, smoking, and lifestyle factors
• Rapid weight changes

Therefore, focusing solely on the nasolabial fold may not always be the most balanced approach. For some individuals, evaluating mid-face support, and for others, planning procedures targeting skin quality, may be more meaningful.

When are thread procedures considered in smile aesthetics?

Thread procedures may be among the options for suitable individuals with mild to moderate tissue laxity who wish to consider a non-surgical approach. The primary goal of the procedure is to support the subcutaneous tissue at selected points and contribute to achieving a more balanced appearance in the facial contour.

In the context of smile aesthetics, threads can be planned by evaluating the tissue relationship starting from the middle part of the face, around the mouth corners, cheeks, and cheekbones. It is not appropriate to apply the same number of threads to everyone or to use a single map. While a limited number of threads may be sufficient for some faces, thread procedures may not be a suitable option for others.

Key factors in selecting suitable individuals include skin thickness, degree of laxity, fat tissue distribution, bone structure, and expectation level. It should be openly discussed that for individuals with advanced skin excess or significant sagging, the change achievable with non-surgical procedures may be limited.

How do thread procedures affect the face?

The material and technique used in thread procedures are determined according to the individual's needs, the target area, and the physician's evaluation. Threads placed under the skin during the procedure aim to provide tissue support at appropriate points. While some types of threads are absorbed over time, a process aimed at supporting the skin's collagen response can also be considered.

However, these applications do not stop the aging process and should not be expected to provide the same effect as surgical facelifts. The aim is not to transform the face into a different shape, but to create more balanced support while preserving the existing facial expression. Therefore, claims such as "eliminating every line" or "providing the same result for everyone" are not medically realistic.

Are only thread procedures used in smile aesthetics?

No. Since the cause of changes in the smile line differs from person to person, thread procedures alone may not always be the ideal approach. In a dermatologist's evaluation, procedures aimed at supporting skin quality, suitable injection-based methods, or energy-based technologies may also be considered according to the individual's needs.

What is important is not to seek a "single procedure," but to understand which layer of the face has undergone changes. For example, fine lines on the skin surface and shadowing due to tissue displacement are not addressed with the same approach. Therefore, while combined plans may be meaningful for some individuals, a simpler and more limited procedure plan may be more suitable for others.

What is important for a natural smile aesthetic?

A natural appearance is not about the application going unnoticed, but about the individual still seeing their own reflection in the mirror. To support a natural outcome in smile aesthetics, the following principles are important:

• Considering the natural asymmetries of the left and right sides of the face
• Not attempting to completely suppress mimic movements
• Not over-intervening in only one area of the face
• Individually evaluating skin quality, volume loss, and tissue laxity
• Setting realistic goals suitable for the individual's age, facial anatomy, and expectations

The lower and middle parts of the face are among the most dynamic areas of expression. Therefore, in every application, the appearance that will occur during a smile must also be taken into consideration. During the examination, both the individual's resting state and mimic movements should be evaluated.

Why is pre-procedure evaluation important?

A detailed evaluation before thread procedures and other aesthetic dermatology options is a fundamental step for patient safety. During the examination, the individual's health history, medications used, allergies, and the presence of active skin infection or inflammation are inquired about. Pregnancy and lactation, bleeding tendencies, connective tissue diseases, and previous procedures can also affect planning.

It is also important to accurately understand the individual's expectations before the procedure. The physician should openly share the potential benefits, limitations, post-procedure process, and possible temporary effects of the applicable method. Informed consent is not just a formal process; it is an important part of enabling the individual to make an informed decision.

What can be seen in the post-procedure period?

The post-procedure process may vary depending on the technique used and the individual's skin structure. Some individuals may experience temporary sensitivity, mild swelling, bruising, or a feeling of tightness. The duration of these effects and care recommendations are shared individually. In the post-procedure period, it is important to adhere to the physician's recommended follow-ups, protect the facial area from trauma, and implement the recommended skin care plan.

Sun protection is important for general skin health and post-procedure care. Especially in a city with high sun exposure like Antalya, using broad-spectrum sunscreen and adhering to individually recommended care steps can contribute to maintaining skin quality.

Who may not be suitable?

The suitability of thread procedures is evaluated individually. When there is advanced skin sagging, active infection, certain connective tissue diseases, uncontrolled chronic conditions, or active dermatological problems in the application area, planning may be postponed or different options may be considered. Therefore, instead of making a decision based on general information from social media, a personal dermatological examination should be performed.
