NCTF 135HA for Neck and Décolletage: What It Can and Cannot Do

The neck and chest often show age and sun damage before the face does, yet they are the areas people forget to treat. NCTF 135HA is a skin booster that the manufacturer says can be injected into the neck and décolletage as well as the face. In practice, it works as a hydration and skin-quality treatment, not a lift. This guide explains what the evidence shows, what a course involves and when another treatment may suit you better. If you would like a doctor to assess your neck and chest, contact CLEO Clinic.

Why the Neck and Décolletage Age Early

The skin on the neck and chest is often thinner than facial skin, and it is exposed to the sun every day. Because it moves constantly with head and shoulder movement, fine horizontal lines tend to deepen over time. In addition, many people apply sunscreen and skincare to the face but stop at the jawline. As a result, texture, dryness and early lines on the neck can appear ahead of the rest of the face. If you are comparing causes and options for loose neck skin, our guide to turkey neck causes and treatments explains the wider picture.

What Is NCTF 135HA?

NCTF 135HA is an injectable skin booster made by FILLMED, a French laboratory. According to FILLMED’s NCTF 135HA page, it contains 5 mg/mL of free (non-crosslinked) hyaluronic acid together with vitamins, amino acids, minerals and other ingredients. Because the hyaluronic acid is not cross-linked, it is used to hydrate the skin rather than to add volume. For a full overview of ingredients, sessions and safety, read our NCTF 135HA treatment page.

Can NCTF 135HA Be Used on the Neck and Décolletage?

Yes. FILLMED states that the product can be injected into the neck and décolletage, which it describes as areas prone to ageing. In addition, several of the manufacturer’s own studies include these areas. However, manufacturer-reported figures should be read with caution, so it helps to look at published trial evidence as well.

What the 2026 Neck Trial Found

A randomised trial published in 2026 tested NCTF 135HA on horizontal neck lines (Jiang et al., 2026). It enrolled 188 adults aged 18 to 70 with moderate to severe neck wrinkles at four hospitals in China. Participants had three sessions about four weeks apart, and an evaluator who did not know which product was used scored the results. NCTF 135HA was compared with another non-cross-linked hyaluronic acid product, and the response rate four weeks after the last session was 88.3% for NCTF 135HA and 85.1% for the comparison product. This met the study’s non-inferiority target, and there were no significant differences between the two products through 24 weeks.

How to Read These Results

Notably, this trial shows that NCTF 135HA performed about as well as a similar hydration product, not that it beat a placebo. Moreover, the study was sponsored by Laboratoires FILL-MED, although the authors reported that the sponsor had no role in its design, analysis or writing. Importantly, the authors acknowledged that 24 weeks is too short to judge how long results last and that the design cannot show which ingredient is responsible. Even so, it is useful evidence that the product is generally well tolerated on the neck, with adverse events mostly mild bruising and swelling. In short, the neck is a reasonable area to treat for lines and skin quality, provided expectations stay realistic.

What to Expect on the Neck and Chest

The most realistic benefits are better hydration, a smoother feel and softer fine, superficial lines. For example, crepey texture and mild dullness on the neck may look fresher after a course. On the other hand, deep horizontal bands, loose skin and visible muscle bands usually need a different approach. Likewise, results build gradually, and they vary between individuals.

How a Neck and Décolletage Session Works

First, the doctor examines your neck and chest, reviews your medical history and confirms that treatment is suitable. Next, numbing cream may be applied to make the injections more comfortable. Then, the product is placed in tiny amounts just under the skin with a fine needle or cannula, across the neck and, if planned, the chest. A session usually takes about 30 to 60 minutes, including numbing time, and larger areas generally need more product than a face-only session.

How Many Sessions Do You Need?

FILLMED recommends a course of three sessions about three weeks apart, followed by at least two courses a year for maintenance. Meanwhile, the 2026 neck trial used intervals of about four weeks, so protocols differ slightly. In practice, your doctor will set the schedule based on your skin and how it responds. Because results are not permanent, maintenance sessions are usually needed to keep the effect.

Risks and Side Effects on the Neck

Most people return to daily activities the same day. Redness, small bumps, mild swelling and itching are common and usually settle within one to two days, although bruises can take a little longer. Because the neck has visible surface veins, bruising is worth planning for, especially before events. Rarely, infection, nodules or allergic reactions can occur. For a full guide to what is normal and when to call your doctor, read NCTF 135HA side effects and aftercare.

Who Should Avoid It

According to FILLMED, NCTF 135HA should not be used in people under 18, during pregnancy or breastfeeding, or where there is a skin disease or alteration in the treatment area. Similarly, it is not suitable if you have a known allergy to any ingredient, or a history of autoimmune disease or immunotherapy. Tell your doctor about blood thinners, cold sores and previous reactions to injectables before treatment.

When Another Treatment May Suit Your Neck Better

NCTF 135HA improves hydration and skin quality, so it will not solve every neck concern. For example, if the main problem is loose skin, a doctor may discuss lifting or tightening options such as Ultherapy Prime or RF microneedling. Meanwhile, brown patches and sun damage respond better to light-based treatment, which our guide to laser treatments for sun-damaged skin and our pigmentation treatment page explain. In addition, a different booster may suit some people better. Our guide to NCTF 135HA vs Profhilo compares two hydration boosters, whereas NCTF 135HA vs Rejuran compares a hydration booster with a polynucleotide.

Protecting Your Results

Daily sun protection matters as much as the injections, because ultraviolet exposure is a major driver of neck and chest ageing. Therefore, apply sunscreen to the neck and chest as well as the face, and reapply it through the day. If you are unsure which type to use, our guide to physical vs chemical sunscreen explains the difference. Finally, avoid heat, strenuous exercise and alcohol for the first 24 to 48 hours after treatment.

How to Choose a Safe Clinic

Choose a clinic where a registered doctor assesses your skin and performs the injections. You can check a doctor’s registration with the Malaysian Medical Council. In addition, injectable medical devices should be registered with the Medical Device Authority (MDA), so it is reasonable to ask about registration. Also, ask to see the sealed packaging, batch number and expiry date before treatment.

Book a Neck and Décolletage Assessment

A short assessment helps confirm whether NCTF 135HA suits your neck and chest or whether another treatment would work better. During the visit, the doctor examines the area, explains your options and gives you a plan and cost before you start. To get started, book a consultation with CLEO Clinic.

Frequently Asked Questions

Does NCTF 135HA tighten or lift the neck?

No. It hydrates the skin and may soften fine lines, but it does not lift sagging skin or remove neck bands.

Can NCTF 135HA treat horizontal neck lines?

It may soften fine, superficial lines. However, the 2026 trial studied moderate to severe lines and compared NCTF 135HA with a similar product, so deeper lines may need other treatments.

How long do neck results last?

Results are gradual and not permanent. The manufacturer suggests maintenance at least twice a year, and your doctor will tailor the plan to your skin.

Is treating the neck more painful than the face?

Most people feel mild discomfort, and numbing cream helps. Sensitivity varies between individuals and between areas.

Can I treat the neck and face in the same visit?

Often yes, depending on your doctor’s plan and the amount of product needed. Your doctor will advise during the consultation.
