When a patient points to a fold and says "this line aged me," they are describing the end effect of a chain of anatomical events. Among them, the retaining ligaments appear often in the facial aging literature, because they help explain why certain lines appear where they do and why the face does not age as a single block.
This page connects ligament anatomy to the clinical reasoning of HOF. It is a review text: it does not indicate points, planes or injection techniques, which are the decision of the qualified professional, after assessment. For the short definition, see retaining ligaments.
What are retaining ligaments?
They are fibrous structures that connect the superficial layers of the face (skin and subcutaneous tissue) to the deep layers (periosteum, fascia, muscle). Instead of loose tissue sliding over bone, the face has fixation points, and the tissues between them behave like "pockets" that can gain or lose volume. This ties in with the concept of the layers of the face and with the SMAS.
Two groups are usually described:
- True: they run from bone to skin, crossing the layers. Classic examples are the zygomatic ligament and the mandibular ligament.
- False: they run from muscle or fascia to skin, without touching bone. The masseteric ligament is a cited example.
The glossary page summarizes the definitions, and there are also the cutaneous ligaments and the platysmal-cutaneous ligaments as useful subdivisions.
Which ligaments matter most in HOF?
| Ligament | Area | Why it matters |
|---|---|---|
| Zygomatic | Cheek, between the cheekbone and the fold | Related to the upper limit of the nasolabial fold and to the transition of the cheekbone area |
| Orbicular retaining | Contour of the orbit | Related to the tear trough groove and to the limit of the eyelid |
| Mandibular | Jaw, near the chin | Related to the pre-jowl sulcus and to jowl formation |
| Masseteric | Lower lateral face | Related to the boundary between the cheek and the masseter area |
Each ligament is an anchor point; what the eye sees is the contrast between the fixed point and the mobile tissue beside it. That is why, over time, the lax tissue "hangs" between the ligaments and the fixed point turns into a fold.
How do ligaments explain laxity?
Laxity does not arise in a single tissue. The facial aging literature describes a set of simultaneous changes:
- Volume loss in fat compartments, which reduces tissue support (see fat compartments of the face).
- Bone resorption in areas such as the orbit, the maxilla and the jaw, which changes the framework the face rests on.
- Ligament loosening, with loss of strength in the fixation points.
- Skin changes, such as loss of elasticity and collagen.
- The action of gravity and muscles, which pull and move the tissues over the years.
The result is what we observe: bags, descent of the midface, jowls, marionette lines, deepening of the nasolabial fold. See also facial aging by layers and midface aging.
This outline is conceptual. Each patient ages differently, through genetics, sun exposure, weight loss, hormones and habits.
What does this change in planning?
Thinking about ligaments shifts the question from "where is the fold" to "what supports this area." This reasoning tends to lead to three clinical reflexes, always at the professional's discretion.
Look at support before the fold
When there is loss of support in the midface, restoring support at a distance can soften the fold without treating it directly. The subject is explored further in malar bags and in lower third laxity.
Choose the tool according to the concern
Fillers replace volume; biostimulators act on tissue quality; threads offer mechanical support with limitations; energy-based technologies work on the skin. None of them "rebuilds" a ligament. The page on PDO threads and the midface and the one on biostimulator in the midface show how each resource is positioned.
Be honest about the limit
If the laxity is significant, non-injectable treatment has a ceiling. The patient should hear, from the consultation onward, that HOF improves harmony and support but is not equivalent to surgery. Harmonization after a facelift shows a scenario in which the anatomy has been modified.
Risks associated with ligament anatomy
Retaining ligaments are crossed by vessels and nerve branches that accompany or pierce them. This reinforces a rule that already applies to any procedure with injectables: know the local anatomy, have hyaluronidase available when hyaluronic acid is used and know how to recognize the signs of vascular occlusion.
In addition, accumulating volume at an anchor point can produce a heavy or irregular look, and excess product in the transition zone between one compartment and another can reveal the outline of the treatment instead of disguising it. The overview of safety and complications covers what is worth reviewing.
Assessment checklist focused on support
How does Harmy help in this conversation?
Harmy does not simulate support, threads or the effect of the ligaments. It simulates volume in the marked areas, which helps show the patient how volume replacement in points such as Cheekbone, Nasolabial Fold and Jawline could change the look of the area.
Use the projection to show that volume in one area can influence how the neighboring one reads, keeping the caveat that it is an illustrative simulation. The full flow is in how to use Harmy.
Review quiz
Understanding the retaining ligaments does not change the product you use, but it changes the question you ask when facing a fold. When the conversation with the patient moves from "removing the line" to "restoring support and proportion in stages," planning tends to be safer and expectations more realistic.
Frequently asked questions
What are the retaining ligaments of the face?
They are fibrous bands that fix the skin and subcutaneous tissue to deeper layers, such as bone and muscle. They work as anchor points that keep tissues in place and delimit fat compartments.
Why do ligaments influence laxity?
With aging, the anchoring can loosen and the tissues between the ligaments descend through gravity and volume loss. The result is deepening folds and the appearance of jowls, which are not explained by the skin alone.
Does filling a fold fix laxity?
Not always. The fold is the visible consequence of tissue descent and loss of support. In many cases, planning thinks first about volume and support at a distance, and only then about the fold itself, at the professional's discretion.
Do thread lifts act on the ligaments?
Threads and biostimulators act through different mechanisms and do not replace the native ligaments. The choice between them depends on assessment, and planning should be realistic about what each resource can do.
Is there a risk when working near the ligaments?
Retaining ligaments are usually accompanied by vessels and nerve branches that cross them. Knowing the local anatomy is part of safety, and the general risks of any injectable still apply.
