Facial skin laxity results from a combination of biological and mechanical changes that develop gradually with age. The skin loses density and elasticity, deeper volumes shift, bone structures change and muscles lose tone. The visible result is a loss of overall harmony, with initially subtle and then more pronounced sagging in different facial areas. This natural process, which can be difficult to accept, is one of the main reasons for consulting in aesthetic medicine.
The first signs rarely appear suddenly. They begin with a subtle change in jawline definition, less firm skin and less distinct contours. Jowls start to develop, nasolabial folds become slightly deeper and the face as a whole appears less supported. A comprehensive, carefully considered approach is important to provide appropriate treatment.
The associated pages describe the different treatment approaches available to correct skin laxity and restore the jawline. They explain reshaping, rejuvenation, jawline redefinition, Texas Face and jawline contouring, together with the precise indications for hyaluronic acid injections in this area.

Texas FaceCauses of skin laxity
Skin ageing is influenced by intrinsic and extrinsic factors that accumulate over time. Biologically, the gradual reduction in collagen, elastin and hyaluronic acid production contributes to dermal thinning and loss of firmness. Facial fat also changes naturally : some compartments diminish while others descend, altering facial fat distribution.
Hormonal changes, sun exposure, smoking, oxidative stress and weight fluctuations can accelerate this process. Bone support itself changes with age, particularly around the jaw and cheekbones, contributing to changes in the facial contour.
Understanding this complex interaction between skin, fat, muscles and bone structure helps identify appropriate, logical solutions.
Clinical signs of skin laxity
Skin laxity develops differently from one person to another. Some first lose jawline definition, while others notice midface sagging or loss of support around the temples. The most commonly affected areas are the jawline, cheekbones, temples, nasolabial fold and lower third of the face.
These changes often make the face look tired or less animated. Yet these signs do not necessarily reflect the patient’s general condition. Appropriate treatment can restore the initial balance without changing the face’s individual character.
Facial assessment : essential before any treatment
A thorough facial assessment is essential before any treatment. It identifies areas that have lost support, changes in volume, structural imbalances and muscle dynamics. This personalised approach takes account of each patient’s facial anatomy, history and personal goals.
An effective treatment plan rests on this detailed assessment, which guides treatment strategies towards a harmonious, natural and lasting result. The aim is never to transform a face, but to restore its balance and freshness.
Skin laxity : hyaluronic acid
Hyaluronic acid is one of the main treatments for correcting skin laxity. Its biomechanical properties help restore lost volume, support tissues, reshape contours and improve jawline definition.
Different types of hyaluronic acid can be used according to the treatment area : some provide deep support, while others reinforce more superficial structures. Injections are often performed around the cheekbones, temples, jawline or chin, following the anatomy of each individual face.
This precise, controlled approach offers subtle, adjustable results that remain fully consistent with the patient’s natural expression.
Skin laxity : botulinum toxin
Botulinum toxin does not act directly on skin quality, but it can complement treatment for skin laxity by modulating certain muscle contractions that increase sagging.
Excessive tension in the platysma muscle can reduce jawline definition. Targeted modulation can help rebalance the pulling and supporting muscle forces, optimising the effects of other treatments.
Botulinum toxin is indicated exclusively for temporary improvement in the appearance of the platysma when it is moderately to strongly visible at maximum contraction and causes significant psychological distress in adult patients.
Improving skin quality
Skin laxity involves more than volume alone. Skin quality, thickness and radiance greatly influence how firm the face appears. When appropriate, complementary treatments can be offered : mesotherapy, Skinboosters, laser photorejuvenation, suitable peels or revitalising techniques.
These treatments stimulate collagen production and improve firmness, creating a more even result that works in synergy with volume correction.
Restoring the jawline
Loss of jawline definition is one of the most common concerns. Goals vary from patient to patient : restoring natural support to the lower third of the face, balancing the lower face or creating a more assertive jaw structure.
Concepts such as jawline contouring and Texas Face pursue more pronounced definition, while other approaches favour subtle rejuvenation. Each technique has its own indications, explained on the dedicated pages.
Comprehensive care for a natural result
The face forms a unique whole. Treating one area without considering its relationship with other structures rarely produces an optimal result. A comprehensive, gradual and personalised strategy can instead restore natural harmony without excess or an artificial appearance.
Treatment quality depends on understanding the patient’s expectations, clinical examination and mastery of injection techniques. The aim remains the same : improve without transforming, rejuvenate without freezing expression and enhance beauty while respecting the face’s individuality.
A review on the chin and jawline describes the use of fillers to restore volume and redefine lower-face contours. Treatment selection considers changes in bone structure, fat and skin. This assessment distinguishes loss of support that injections can correct from laxity requiring another treatment.
A systematic review bringing together 121 publications on facial and neck radiofrequency reports improvements in firmness, elasticity and skin quality. Satisfaction is particularly favourable in patients seeking measured correction. These data clarify the role of radiofrequency when skin laxity contributes to loss of facial contour definition.
An international consensus on hyaluronic acid injections proposes recommendations for several indications, including jawline definition. The authors stress anatomical examination, gel selection and procedural precision. These guidelines enable personalised contour correction to be planned, taking account of facial proportions and tissue thickness.
Frequently asked questions about the jawline in Geneva
What is jawline laxity ?
Jawline laxity is a loss of firmness and definition of the facial contours, particularly around the jaw, cheeks and lower face. It results from tissue sagging and a reduction in collagen, elastin and subcutaneous fat.
At what age does jawline laxity begin ?
It usually begins between 35 and 45 years of age, but varies with genetics, hormones and lifestyle (smoking, sun exposure, stress, weight loss, etc.).
What are the earliest signs of facial laxity ?
Early signs include a less distinct jawline, emerging jowls, slight cheek sagging, volume loss and less balanced contours.
What are the main causes of jawline laxity ?
There are several causes : natural skin ageing, loss of collagen and elastin, depletion of facial fat compartments, muscle laxity, sun exposure, lifestyle and changes in weight.
How can the sagging of the facial oval be prevented ?
Prevention involves a healthy lifestyle, sun protection, hydration, suitable dermatological skincare and sometimes gentle medical treatments to stimulate collagen synthesis.
Which aesthetic medicine treatments can redefine the jawline ?
The main options are hyaluronic acid injections, collagen stimulators, thread lifts, radiofrequency, focused ultrasound (HIFU) or sometimes a combination of techniques.
Can hyaluronic acid injections improve the jawline ?
Yes. Hyaluronic acid restores volume, reshapes contours and supports tissues. It can improve the jawline, cheeks and jowls naturally and gradually.
