3 Lessons | 31 Minutes | Instructor: Rabia Sannam Khan

Master a structured clinical approach to lower-face aesthetics, neuromodulation, chin augmentation, and jawline contouring with this focused OHI-S aesthetic medicine course.

OHI-S Lower-Face Aesthetics: Neuromodulation, Chin & Jawline Contouring connects facial assessment, applied anatomy, botulinum toxin techniques, dermal fillers, and individualized treatment planning to help aesthetic practitioners achieve more balanced and predictable lower-face rejuvenation.

The course focuses on the lower third of the face, helping practitioners understand how facial proportions, muscular activity, skeletal support, chin projection, and mandibular definition interact to influence overall facial harmony.

Through three concise lessons, participants review facial symmetry and gender-specific profiling, high-risk lower-face anatomy, evidence-based BoNT-A applications, chin augmentation, jawline sculpting, and combination protocols using neuromodulators and hyaluronic acid fillers.

Course Curriculum

Lesson 1: Facial Symmetry & Proportions – Lower-Third Assessment & Gender Profiling

This lesson introduces the role of the lower third of the face in overall facial attractiveness, balance, and harmony.

Participants examine how facial proportions, skeletal relationships, and asymmetries influence aesthetic treatment planning.

Topics Include:

• Facial harmonization and symmetry
• Importance of the lower facial third
• Principles of facial proportion and balance
• Structural framing of the lower face
• Causes of lower-face asymmetry
• Clinical assessment of mandibular asymmetry
• Quantitative evaluation of facial proportions
• Lower-third facial assessment
• Gender-specific lower-face characteristics
• Feminine versus masculine facial profiling
• Facial proportion analysis
• Golden Ratio principles in aesthetic planning

Understanding these variables helps practitioners avoid standardized treatment approaches and instead design procedures according to each patient’s facial architecture.

Lesson 2: Lower-Third Applied Anatomy & Evidence-Based Neuromodulation

The second lesson focuses on the anatomy required for safe and effective lower-face injectable treatment.

Practitioners review important mandibular landmarks, facial muscles, vascular anatomy, and structures that influence lower-face shape and movement.

Applied Anatomy Topics

• Facial and mandibular anatomical landmarks
• Lower-third facial anatomy
• Muscle complexes of the lower face
• Neurovascular anatomy
• Facial artery anatomy
• High-risk vascular regions
• Depressor Anguli Oris (DAO)
• Mentalis muscle
• Masseter anatomy
• Functional interactions between lower-face muscles

Neuromodulation Topics

The course reviews evidence-based applications of Botulinum Toxin A for lower-face aesthetic treatment.

Applications include:

• Masseter neuromodulation
• Masseter reduction
• Jawline slimming
• Lower-face symmetry improvement
• DAO treatment
• Mentalis treatment
• Depressor muscle relaxation
• Lower-face posture optimization

Participants also examine how to select between:

• Botulinum toxin
• Dermal fillers
• Combination treatment

depending on the anatomical and aesthetic needs of the patient.

Masseter Reduction & Jawline Slimming

Masseter hypertrophy can contribute to increased lower-face width and a more square facial appearance.

The course reviews how neuromodulation of the masseter may be incorporated into treatment planning to achieve:

• Reduced lower-face width
• Improved mandibular contour
• Better facial symmetry
• More defined jawline proportions

Treatment should be individualized according to facial structure, gender-specific aesthetic goals, muscle activity, and desired outcome.

DAO & Mentalis Neuromodulation

Muscle activity within the lower face can significantly influence the appearance of the chin, mouth corners, and mandibular region.

The program examines targeted treatment strategies involving:

Depressor Anguli Oris – DAO

Understanding DAO anatomy can help practitioners appropriately manage excessive downward pull affecting the corners of the mouth.

Mentalis

Appropriate neuromodulation of the mentalis can help address unwanted muscular activity while preserving normal lower-face function.

Lesson 3: Chin Augmentation, Jawline Sculpting & Combination Protocols

The third lesson moves from neuromodulation to structural lower-face enhancement.

Participants learn how dermal fillers can be incorporated into treatment plans to improve chin projection, mandibular contour, and overall lower-face proportions.

Chin Augmentation

Chin shape and projection play an important role in facial profile and lower-third balance.

The course reviews:

• Chin assessment
• Chin proportions
• Chin projection
• Projection angles
• Structural characteristics
• Patient selection
• Treatment planning
• Dermal filler strategies
• Facial balance after augmentation

Rather than treating the chin as an isolated structure, practitioners are encouraged to evaluate its relationship with the lips, jawline, nose, and overall facial profile.

Jawline Contouring & Sculpting

Jawline definition depends on multiple anatomical structures, including bone, soft tissue, muscle activity, and facial volume distribution.

The course provides a structured framework for:

• Jawline assessment
• Mandibular anatomy
• Treatment area selection
• Structural filler placement
• Improving jawline definition
• Lower-face contouring
• Facial profile enhancement
• Achieving balanced mandibular proportions

Combination Treatment Protocols

Lower-face aesthetic concerns frequently involve multiple anatomical layers and may not be adequately addressed using a single treatment modality.

The course therefore examines integrated protocols combining:

Botulinum Toxin A

Used to modify excessive muscle activity and influence lower-face shape.

Hyaluronic Acid Fillers

Used to improve structural support, chin projection, and mandibular definition.

Combining these approaches appropriately can help practitioners achieve synergistic results while maintaining natural facial function.

Treatment Planning & Procedural Sequencing

Participants learn to connect:

Facial Analysis → Anatomy → Diagnosis → Modality Selection → Treatment Sequence → Outcome Evaluation

This structured workflow supports individualized aesthetic treatment rather than relying on standardized injection patterns.

The course also emphasizes realistic patient expectations, appropriate case selection, procedural sequencing, and complication prevention.
