Neck and Décolleté Aging

Why might the neck and décolleté not age as well as the face?

The skin on the neck and décolleté does not have the same biological characteristics as the skin on the face.

In these regions:

The skin may be thinner,

Pilosebaceous unit density is lower.,

The natural amount of sebum may be less.,

The healing capacity may be more limited in some areas of the face compared to others.,

Chronic sun exposure can be noticeable.

In addition, the neck is an anatomical region that is constantly in motion. Flexion, extension, and rotation of the head can contribute to the prominence of horizontal lines over time.

Age-related loss of dermal collagen and elastin also makes these mechanical effects more visible.

Why is sun damage particularly noticeable on the décolleté area?

The décolletage area can be exposed to intense ultraviolet radiation over the years.

Chronic ultraviolet (UV) exposure:

It can increase collagen breakdown.,

It can disrupt the elastic fiber structure.,

It can disrupt pigment distribution,

It can increase the visibility of blood vessels.,

It can contribute to epidermal and dermal atrophy.

Therefore, in photo-aged décolletage, there is often not just "spots" but also:

pigment + blood vessel + tissue + atrophy

It is found.

What is Poikiloderma of Civatte?

Poikiloderma of Civatte is a chronic photodamage pattern seen particularly on the lateral surfaces of the neck and upper décolleté.

Typical appearance:

brown pigmentation,

redness,

telangiectasias,

fine atrophy

It is a combination.

It is characteristic that the area under the chin, which is naturally protected from the sun, is relatively less affected.

Chronic sun exposure is one of the key factors; sensitization through contact with perfumes and cosmetics may also contribute in some patients.

Do horizontal lines on the neck only appear with age?

No.

Horizontal neck lines can also be seen in young people.

In its formation:

anatomy,

genetic predisposition,

repetitive neck movements,

loss of dermal support,

skin thinning,

decreased hydration

They can play roles together.

“While "tech neck" is a commonly used term in everyday language, phone use alone isn't the sole cause of neck lines.

Can hyaluronic acid be used on neck lines?

Yes.

Hyaluronic acid (HA)-based injections can be used in selected horizontal necklines.

Aim:

to support the base of the line,

to reduce surface depression,

to increase hydration,

improving skin quality in some patients

it could be.

In a 2022 multicenter randomized study, a combination of non-cross-linked HA-based injections + mesotherapy was found to be more effective than botulinum toxin type A (BoNT-A) treatment in terms of neckline severity in moderate to severe horizontal necklines.

A systematic review and meta-analysis of 2026 evaluated 11 studies and 379 patients; it reported that HA fillers provided significant clinical improvement in horizontal neck lines, and that side effects were largely mild and temporary.

Will skin enhancement injections work on the neck?

Yes, but it's important to define the target correctly.

HA injections that are not cross-linked or are intended for low structural support are particularly suitable for:

hydration,

fine surface lines,

elasticity,

skin quality

It can be beneficial.

A prospective, multicenter, randomized study from 2026 showed significant improvement in neck lines and patient assessments in 188 individuals with moderate to severe neck wrinkles after injections of non-cross-linked HA-based injections.

However, skin quality is noticeably affected by the injection:

excess skin,

platysma band,

advanced neck laxity

It is not a method that fixes everything on its own.

Can biostimulants be used in the neck?

Yes.

Biostimulants, particularly calcium hydroxylapatite (CaHA), can be used with diluted or hyperdiluted techniques to provide dermal support and promote collagen remodeling.

In a 2023 study, 22 women with mild-to-moderate cervical aging were treated with two sessions of hyperdiluted CaHA:

in the neck lines,

in looseness,

dermal thickness

iyileşme gösterilmiştir. Ultrasonografik olarak dermal kalınlık ortalama yaklaşık %15 artmıştır.

While this data is significant, the study was small, uncontrolled, and conducted on only one arm. Therefore, presenting CaHA as "the most proven superior method for neck rejuvenation" would not be accurate.

Can CaHA, HA, and botulinum toxin be used together?

There is interesting, but currently limited, data regarding the combined approach.

In 15 pilot studies published in 2024, CaHA, HA, and incobotulinum toxin type A were used in combination in the same session for neck rejuvenation, and positive clinical results were reported. (Wiley Online Library)

Another small prospective study published in 2026 also reported improvement in neck laxity and clinical appearance with the CaHA + HA + BoNT-A combination.

However, these studies are small and exploratory. Therefore:

“"Mixing the three is the standard neck protocol"”

It's too early to draw conclusions.

What does botulinum toxin treat in the neck?

The primary target of BoNT-A is platysma muscle activity.

Especially:

Prominent vertical platysma bands,

Downward platysmal shot along the lower face-jawline,

dynamic neck view

It can be used in selected patients.

In a 2025 phase 3 randomized, double-blind, placebo-controlled study, onabotulinumtoxinA demonstrated significant superiority over placebo in both physician and patient assessments in patients with moderate to severe platysma prominence.

A systematic review and meta-analysis of 2026 evaluated three randomized controlled trials and 912 patients; onabotulinum toxin A was reported to significantly improve platysma prominence, with side effect rates similar to placebo.

Therefore, there is an evidence base for botulinum toxin A in the neck and jawline, particularly regarding platysma prominence, supported by randomized controlled trials; however, results depend on patient anatomy, dose, and application technique.

Can botulinum toxin also treat horizontal neck lines?

It may reduce dynamic contribution in some patients, but the underlying structural problem of the horizontal neckline is not always muscular.

In a 2022 randomized study, a combination of HA-based injections and mesotherapy showed better results than BoNT-A in reducing horizontal neck lines.

Because:

Vertical platysma band → Stronger indication for BoNT-A; horizontal static line → HA/dermal support may be more rational.

It would be more accurate to think of it that way.

Does radiofrequency work on the neck?

Yes.

Radiofrequency (RF) aims to stimulate collagen contraction and remodeling over time by generating controlled heat in the skin.

A 2022 systematic review examined 121 studies on facial and neck rejuvenation; RF's:

skin laxity,

elasticity,

overall aesthetic appearance

It has been reported to provide improvement. Patient satisfaction has been found to be higher, especially in individuals with modest expectations of natural rejuvenation.

However, different RF devices:

monopolar,

bipolar,

multipolar,

microneedle RF

They have different physical characteristics. “RF” is not a single standard process.

Can RF microneedling / gold needle be used in this area?

Radiofrequency microneedling (RF microneedling) delivers RF energy to the dermis via microneedles.

Especially:

thin, wrinkled and crepe-like texture,

fine lines,

slight looseness,

dermal quality loss

It can be used in selected patients.

Due to the thin skin and low subcutaneous tissue characteristics of the neck area:

needle depth,

energy,

shot density

It should be adjusted more carefully according to the face.

Can microfocused ultrasound be used on the neck?

Yes.

Microfocused ultrasound (MFU), or its imaging-guided form Microfocused Ultrasound with Visualization (MFU-V), creates focal thermal coagulation in deeper fibrous septa and supporting tissues while largely protecting the epidermis.

In a 2024 randomized, investigator-blind study, MFU-V was applied to the lower face and upper neck of 51 patients, demonstrating jawline and neck tightening in both standard and anatomy-customized protocols.

Therefore, the role of MFU-V is particularly important:

mild to moderate looseness,

lower face-neck transition,

jawline contour

It is on it.

It is not a primary treatment for pigment or surface irregularities.

Are high-intensity focused ultrasound (HIFU) and mFU the same thing?

In everyday clinical terminology, they are interchangeable; however, technically, not all devices are the same.

High-intensity focused ultrasound (HIFU) refers to a broad group of technologies.

MFU, and specifically MFU-V, describes more specific, controlled focused ultrasound systems used in aesthetic applications.

Therefore, it is not necessary to automatically transfer the results of a group of devices from the literature to all "HIFU" devices on the market.

Can fractional laser be used on the neck and décolleté area?

Yes, but the same tolerance as for the face should not be assumed.

On the neck and décolleté:

epidermal healing capacity,

pilosebaceous reserve,

scar risk,

risk of post-inflammatory hyperpigmentation

It can be different from that.

Therefore, conservative parameters and appropriate patient selection are particularly important in ablative fractional systems.

Fractional therapies:

tissue,

fine line,

photo damage,

some pigment components

It can be used for.

However, higher energy doesn't always mean better results.

What is the place of the 1927 nm thulium laser?

The 1927 nanometer thulium laser primarily uses water as a chromophore and produces a fractional effect in the epidermis/upper dermis.

Especially:

superficial photodamage,

epidermal pigment disorder,

skin tissue

It can be used for.

However, it should not be considered in the same way as melanin-selective 532, 755, or 1064 nm lasers.

It can be used cautiously on chronically sun-damaged areas such as the décolleté; parameter selection is even more important if there is a high phototype, a history of post-inflammatory hyperpigmentation (PIH), or active inflammation.

When is intense pulsed light (IPL) meaningful for the neck and décolleté area?

Intense pulsed light (IPL) is not a laser with a single wavelength; it uses selected bands from a broad light spectrum with different filters.

Like Poikiloderma of Civatte:

Pigment + telangiectasia + widespread photodamage

It can be meaningful in combination.

In the literature on poikiloderma, IPL and vascular lasers have long been used as methods.

However, the risk of burns and PID due to high phototype epidermal melanin absorption should be considered.

Can vascular lasers be used for poikiloderma?

Yes.

Vascular-targeted lasers can be used, especially for the vascular component of Poikiloderma of Civatte.

In 2022, a study of 14 patients showed mild to moderate clinical improvement after a single session with a 577 nm yellow laser; only short-term mild erythema was reported. Researchers noted that repeated sessions may be necessary for a complete response.

However, the study is small and uncontrolled; it does not prove the superiority of standard treatment.

Can Q-switched or picosecond lasers be used?

Melanin-targeted treatment for well-circumscribed benign epidermal pigmentations:

Q-switched,

picosecond

Lasers can be used.

However, since widespread photodamage in the neck/décolleté area is usually not caused solely by pigment, pigment laser alone is not an option:

vein,

atrophy,

looseness,

tissue

It does not dissolve its components.

Therefore, a combination approach is more rational in multi-component photodamage.

What is the purpose of Endolift in the neck?

Endolift aims to deliver energy to deeper tissues and fibroseptal structures via subdermal fibers.

Especially:

submental contour,

mild to moderate tissue laxity,

jawline-neck transition

It can be used for.

However, Endolift:

epidermal pigment,

poikiloderma,

superficial fine line

It is not a treatment.

Therefore, even when used in neck rejuvenation, it should be positioned as a method that targets the deep tissue component.

Are décolleté spots always sunspots?

No.

In the décolleté area:

solar lentigo,

diffuse photodamage,

PIH,

Pigmentation after contact dermatitis,

photocontact dermatitis,

poikiloderma

It can similarly be described as a "stain".

Therefore, clinical diagnosis before the procedure is important.

Can perfume affect neck pigmentation?

Yes.

Perfume and some cosmetic ingredients:

irritant contact dermatitis,

allergic contact dermatitis,

photocontact dermatitis

It can create.

Perfume contact sensitization has been identified as a possible contributing factor in the pathogenesis of Poikiloderma of Civatte.

In patients with recurrent neck dermatitis, patch testing or, in special cases, photopatch testing may be considered when necessary.

Can retinoids be used in the neck?

Yes.

Topical retinoids in photoaging:

epidermal cellular regeneration,

collagen metabolism,

fine lines,

pigment disorder

It might be useful.

However, the neck may not tolerate it as well as the face.

Because:

to start with a low frequency,

moisturizing support,

Reduce if irritation develops.

That might be more suitable.

Why is sunscreen important for the neck and décolleté?

Because sustained improvement from procedural treatment depends on reducing new UV damage.

Sunscreen:

the progression of pigmentation,

collagen damage,

new photoaging

It helps to reduce it.

The neck and décolleté should be protected as regularly as the face in daily photoprotection.

Is there a single "neck rejuvenation" procedure?

No.

First, the main problem must be identified:

Vertical platysma bands

→ BoNT-A

Horizontal static necklines

→ HA-based injection/dermal support

Dermal thinning and loss of quality.

→ CaHA or selected biostimulation/skin-quality methods

Slight looseness

→ RF, MFU/HIFU, and selected other tightening systems

Pigment + blood vessels

→ IPL or targeted pigment/vascular system

Tissue and photo damage

→ microneedling, RF microneedling, or suitable fractional method

This classification is more rational than the "one device for everyone" approach.

Why might combination therapy be necessary?

Because aging in the neck area is a multi-layered process.

In the same patient:

Platysma activity,

horizontal lines,

dermal thinning,

looseness,

pigment,

vein appearance

They can be found together.

Therefore, the success of treatment often comes from treating the right target at the right level.

Combination therapy doesn't mean all procedures are performed on the same day. Procedures can be planned in stages, depending on the anatomical target, risk of inflammation, and healing time.

When do non-surgical methods reach their limits?

Evident:

excess skin,

platysmal decomposition,

severe submental tissue alteration,

advanced cervicomental contour loss

If available, the improvement that non-surgical methods can provide is limited.

Presenting energy-based procedures as "non-surgical neck lift" in these patients is not realistic.

Dermatologist's Note

When it comes to neck and décolleté rejuvenation, the fundamental question for me is:

“The question isn't "Which device should we make?", but rather "Which anatomical component has aged?"”

That is the question.

I would roughly divide the neck into the following categories:

1. Epidermal pigment and photodamage 2. Vascular redness and telangiectasias 3. Dermal thinning and skin quality 4. Horizontal neck lines 5. Platysma activity and vertical bands 6. True tissue laxity and contour loss

For example, attempting to resolve the platysma band with a laser, pigment with BoNT-A, or advanced laxity with skin quality injections is anatomically incorrect targeting.

The goal of treatment is not to perform as many procedures as possible; it is to treat the problem at the correct level with the least possible intervention.

Frequently Asked Questions

Can horizontal neck lines be treated with fillers?

Yes. There are randomized trials and current meta-analyses showing clinical improvement with HA-based injections.

What part of the neck does botulinum toxin primarily affect?

The strongest current data are on vertical platysma prominence and platysmal imaging.

Does CaHA work in the neck?

Small clinical trials have shown improvement in dermal thickness, horizontal lines, and laxity; however, the level of evidence is not as high as in large randomized trials.

Does HIFU eliminate neck wrinkles?

Its primary goal is not superficial wrinkles, but deeper tissue tightening. There is randomized data available for lower face and upper neck tightening with MFU-V.

Can IPL be used for poikiloderma?

Yes. It is one of the options used for poikiloderma where both pigment and vascular components are present.

Can the neck withstand as aggressive laser treatment as the face?

Not always. The neck and décolleté area may require more careful parameters and patient selection.
