Fillers & Botox

Overview: Fillers, Botox and the Liquid Facelift

Fillers, botulinum toxin (Botox) and the liquid facelift are three fundamental non-invasive approaches to facial rejuvenation, all performed in an office setting and working through different mechanisms. Although they are discussed under a single heading, they address different problems and are not alternatives to one another — more often, they are complementary.

The differences in brief:

• Fillers are gel-like substances injected into areas with volume loss or insufficient contour; they replace missing tissue.
• Botulinum toxin temporarily reduces the activity of the muscles of facial expression, softening expression lines; it does not add tissue, it relaxes the muscle.
• The liquid facelift is an approach that re-volumises the facial tissue through a strategic combination of multiple filler points; it does not replace a surgical facelift but offers an alternative concept.

The modern approach to aesthetics has moved away from the exaggerated, “artificial” look. Correct indication, measured dosing and realistic expectations are the foundation of a natural result. All three treatments are planned according to individual anatomy, skin structure and lifestyle; there is no standard prescription.

When It Is Considered

The reasons for seeking non-invasive facial treatments generally fall under the following headings:

• Age-related volume loss — hollowing of the cheekbones, cheeks and temples
• Increasingly prominent expression lines — forehead, between the brows, around the eyes
• Deepening static wrinkles
• Loss of lip volume or definition of the lip border
• Reduced clarity of the jawline, formation of jowls
• Under-eye hollowing, a “tired” appearance
• Loss of skin elasticity, fine lines
• Mild structural asymmetries
• Correction of previous treatments (in suitable cases)

In cases of significant sagging, advanced skin laxity or a need for structural correction, non-invasive methods alone may not be sufficient; in such situations, surgical options are considered.

Filler Treatments

What They Are and How They Work

Fillers are gel-consistency products injected to address volume deficiency in the skin and to redefine contours. The most commonly used type is hyaluronic acid (HA)–based fillers. Hyaluronic acid is a molecule that occurs naturally in the body; it binds water at a high rate, giving tissue volume and elasticity. It is gradually absorbed by the body over the years, which makes it a reversible treatment.

Other types of filler:

• Calcium hydroxylapatite (CaHA): products that provide more structural support and have a collagen-stimulating effect
• Poly-L-lactic acid (PLLA): bio-stimulatory products that, rather than adding volume directly, trigger collagen production in the skin. The effect appears gradually over several months.
• Polycaprolactone (PCL): combination fillers that provide long-lasting collagen stimulation

An important advantage of hyaluronic acid fillers is that they can be dissolved when needed using an enzyme called hyaluronidase. This safety advantage is the main reason HA is most often preferred for initial treatments.

Treatment Areas

Fillers can be used in almost any region of the face. The most common areas of application are:

• Cheekbone and cheek volume: correction of age-related volume migration
• Nasolabial fold (the line from the nose to the mouth): softening of deepened lines
• Marionette lines: the folds running from the corners of the mouth down to the chin
• Lips: adding volume, defining the border, correcting symmetry
• Jawline: clarity, profile correction
• Chin: increasing projection
• Under-eye (tear trough): correction of hollowing — this area requires care and an experienced hand
• Temples: correction of age-related hollowing
• Nose (non-surgical rhinoplasty): mild structural corrections — in suitable cases
• Back of the hand: softening the signs of ageing

Each area requires a filler of a different viscosity. Soft products are preferred for the lips, while products providing structural support are chosen for the chin.

The Treatment Process

A consultation is carried out before the procedure; the anatomical plan and target area are clarified with the support of photographs. On the day of treatment:

1. Skin cleansing and application of topical anaesthetic cream (15-20 min)
2. Injection with a fine cannula or needle, depending on the area
3. Manual moulding to check distribution
4. Cold application

The procedure takes between 15 and 45 minutes depending on the area. The patient can return to social life the same day. Mild swelling, redness and, rarely, bruising may occur in the first 24-48 hours; this is a temporary picture.

Recovery and Results

Results are largely visible immediately, with final settling occurring within 1-2 weeks. The duration of hyaluronic acid fillers varies according to the area, the product used and metabolism:

• Lips: 6-12 months
• Nasolabial fold: 9-12 months
• Cheekbone / cheek: 12-18 months
• Chin / jawline: 12-18 months

The effect of bio-stimulatory fillers such as CaHA and PLLA may last longer; as a result of collagen stimulation, it continues at a gradual and more sustained level.

Common Misconceptions About Fillers

• “Fillers are permanent” — The widely used HA fillers are not permanent; they are absorbed by the body. The permanent fillers used in the past and no longer preferred today (silicone, PMMA) have been abandoned because of their serious complication profile.
• “A single treatment makes you ‘young’” — Fillers manage volume loss, not age. Skin quality, laxity and the overall ageing process require different approaches.
• “Fillers make you look exaggerated” — A natural appearance is possible with measured dosing, the right product and an experienced hand. The “over-filled” look is usually the result of incorrect indication or excessive quantity.

Botulinum Toxin (Botox)

What It Is and How It Works

Botulinum toxin type A is a protein produced by the bacterium Clostridium botulinum, prepared in highly purified form for medical use. By temporarily blocking the communication between the muscle and its nerve endings, it reduces the strength of muscle contraction. In this way, dynamic wrinkles caused by facial movements are softened, and their progression into static wrinkles over time is even slowed.

Botox does not add tissue; it is not a filler. On its own, it does not resolve volume loss or contour problems. Its main effect is on muscle activity; for this reason, treatment areas and doses are planned on an individual basis.

Beyond aesthetics, it is also used therapeutically in the following conditions:

• Excessive sweating (hyperhidrosis)
• Migraine prophylaxis (in suitable cases)
• Bruxism (teeth grinding)
• Hypertrophy of the jaw muscle
• Spasmodic torticollis and other movement disorders

Treatment Areas

The most common areas for aesthetic purposes:

• Forehead lines — horizontal lines
• Between the brows (glabella) — the “frown line”
• Around the eyes (crow’s feet) — expression lines spreading to the sides
• Lines at the bridge of the nose (bunny lines)
• Upper lip lines — together with a gummy smile
• Jawline refinement — masseter (chewing muscle) slimming
• Neck bands (platysma)
• Brow lift — with a measured dose

The dose varies according to the area and the patient’s muscle structure. As muscle volume is generally greater in male patients, the dose differs.

The Treatment Process

The treatment takes 10-20 minutes and does not require anaesthesia. Calculated micro-doses are delivered to multiple points with a fine needle. Topical anaesthetic cream may optionally be used.

After the procedure, there may be brief mild redness and, rarely, small bruises. In the first 4-6 hours:

• The treated area should not be massaged
• Bending over excessively or keeping the head down is not advised
• Saunas and strenuous exercise should be avoided

Onset and Duration of Effect

The effect of Botox is not immediate. The typical course:

• Days 3-4: the first effects begin to be felt
• Days 7-14: the final effect settles; this is the most suitable interval for a follow-up examination
• Months 3-4: the effect slowly begins to diminish
• Months 4-6: a new dose may be required

With regular treatment, the effect may last longer in some patients as the muscle habit decreases. Individual metabolism, muscle structure and dose are the determining factors.

Risks and Limitations

The main potential side effects of botulinum toxin:

• Temporary drooping of the eyelid or brow (ptosis): may occur with an incorrect dose or an inaccurate plan; it is temporary and resolves within weeks
• Asymmetry: usually mild and temporary
• Local bruising or tenderness
• Headache: may occur with the first treatments, short-lived
• Less or more effect than expected: corrected with dose adjustment

Contraindications:

• Pregnancy and breastfeeding
• Active infection at the treatment site
• Neuromuscular diseases (myasthenia gravis, Lambert-Eaton, ALS)
• Use of aminoglycoside-group antibiotics (risk of interaction)
• A history of a serious reaction to botulinum toxin

The Liquid Facelift

What It Is and How It Works

The liquid facelift (non-surgical facelift) is a concept that aims to re-volumise the facial tissue holistically through a strategic combination of multiple filler points and, where needed, botulinum toxin. It is not the filling of a single area; the face is assessed as a whole, and volume migration, loss of contour and weakness of projection are addressed simultaneously.

The name “liquid facelift” can be misleading — this treatment does not replace a surgical facelift (rhytidectomy). Whereas a surgical facelift physically repositions sagging skin and muscle, the liquid facelift creates the impression of a “lift” by balancing volume migration. It falls short in patients with advanced sagging or marked skin laxity; in middle age and the early signs of ageing, however, it can make a noticeable difference.

The Treatment Process and Planning

A detailed facial analysis is carried out before treatment. The face is assessed using vectors and volume maps:

• Cheekbone projection
• Temple volume
• Mid-cheek support
• Clarity of the jawline
• Chin projection
• Lip contour and volume ratio
• The under-eye transition line

The plan is personalised and staged. Everything does not have to be done in a single session; in some patients, reaching the goal over 2-3 separate sessions gives a more natural result. The total amount of product and the combination are determined according to the patient’s anatomy and goals.

Who the Liquid Facelift Is Suitable For

• Patients in middle age with early signs of ageing
• Cases that are not suitable for surgery or do not yet require it
• Those considering a particular pre- or post-surgical period as a bridging process
• Those seeking a temporary and reversible approach (especially with HA-based treatments)

Situations where it may not be suitable:

• Advanced sagging, marked skin laxity
• Cases where the expectation is at a surgical level
• Situations where previous heavy filler treatments have dispersed and the tissue reserve has deteriorated

Recovery and Results

Mild swelling, redness and pinpoint bruises are normal in the first 24-48 hours after treatment. Social life usually resumes the same or the following day; however, planning 2 weeks ahead of an important event is the wiser choice.

The duration of results depends on the products used. HA-based combinations give results lasting 9-18 months, while bio-stimulatory combinations last over a longer interval.

General Risks and Points to Note

There are common safety principles across all three types of treatment:

• The practitioner’s experience is decisive. Anatomical knowledge, product selection and dose calculation directly affect the quality of the result.
• Sterile technique: all treatments should be carried out in a medical centre, under sterile conditions.
• Licensed products: products approved by the Turkish Ministry of Health / the manufacturer should be used.
• Vascular complications (fillers): intravascular injection is a rare but serious complication. An experienced practitioner, the use of a cannula and anatomical knowledge minimise this risk.
• Aspirin and blood thinners: these may be adjusted a few days before treatment on a doctor’s advice.
• Active skin infection, cold sores: treatment is postponed.
• Pregnancy and breastfeeding: treatments are not recommended during these periods.

Contraindications must always be assessed during the consultation; the patient’s disclosure of all chronic illnesses, medication use and previous treatments is the foundation of a safe result.

Comparison of Fillers, Botox and the Liquid Facelift

Heading	Fillers	Botox	Liquid Facelift
Mechanism	Adds volume	Reduces muscle activity	Volume + contour combination
Type of problem	Structural volume loss	Expression wrinkles	Holistic ageing
Onset of effect	Immediate	3-14 days	Immediate + settles over time
Duration	6-18 months	3-6 months	9-18 months
Reversibility	Yes for HA (hyaluronidase)	The effect fades naturally	Yes if HA
A surgical alternative?	No, a temporary solution	No	Not in place of a surgical facelift

The right choice is the match between the patient’s problem and the mechanism of the treatment. Using fillers for expression lines alone, or Botox for volume loss, is applying the wrong tool to the wrong problem.

When to Consult a Specialist

If you are troubled by age-related changes in your face or by structural volume deficiencies, an assessment with an aesthetic surgeon or an experienced dermatologist is appropriate. In the consultation, the priority is to answer not the question “what can be done” but “what needs to be done.”

For patients who have previously had fillers or Botox at other clinics and are not satisfied with the result, revision planning is more complex; clarifying the filler history (what, when and how much) is critical for safe intervention. In cases that have been over-filled, dissolution with hyaluronidase and planning from scratch is sometimes the most appropriate approach.

Before deciding on an aesthetic treatment, it should be remembered that realistic expectations, correct indication and appropriate product selection determine the result. Not every treatment is right for every patient; the right one is the approach best suited to your anatomy and goals.
