Quick answer: Neck wrinkles and loose neck skin are treated in Korea with lifting devices such as HIFU and radiofrequency, skin boosters for horizontal "necklace" lines, Botox for vertical neck bands, and gentle lasers for texture. Most people need a combination and a few sessions. Downtime is usually short.
Key takeaways
- Neck skin is thin and ages quickly, but it is often forgotten in skincare.
- Horizontal lines respond well to skin boosters.
- Vertical neck bands can be relaxed with Botox.
- HIFU and RF tighten loose skin under the jaw and on the neck.
- Daily sunscreen on the neck helps results last.
What causes neck wrinkles and loose skin?
- Horizontal lines ("tech neck" or necklace lines): from bending the neck and loss of hydration.
- Vertical bands: from the platysma muscle becoming more visible with age.
- Loose skin: from loss of collagen and elasticity.
- Sun damage: the neck is often not protected with sunscreen.
Neck treatments are increasingly popular with visitors to Seoul. Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare.
Which treatments work best?
1. HIFU lifting
Focused ultrasound tightens the deeper layers under the jaw and on the neck. Results build over two to three months. See our Ultherapy Prime guide and HIFU lifting.
2. Radiofrequency (Thermage FLX)
RF heats the skin evenly, which improves firmness and crepey texture. It is often combined with HIFU. See Thermage FLX.
3. Skin boosters for necklace lines
Boosters such as Rejuran or HA boosters improve hydration and thickness, so horizontal lines look softer. Usually two to three sessions are needed. See Rejuran Healer in Korea and Skinvive in Korea.
4. Botox for neck bands
Small doses of Botox relax the vertical bands of the platysma muscle, which can make the neck and jawline look smoother. Results last about three to four months. See Botox in Gangnam.
5. Lasers and collagen stimulators
Gentle lasers improve texture and pigment on the neck. Collagen stimulators such as Juvelook help thin, crepey skin. See our Juvelook guide.
Which option is right for me?
- Horizontal lines: skin boosters, sometimes with a little soft filler.
- Vertical bands: Botox.
- Loose skin under the jaw: HIFU or RF. See treatments for jowls.
- Crepey texture and sun damage: lasers and boosters.
What is the downtime?
- HIFU and RF: mild redness or tenderness for a few days.
- Skin boosters: small bumps for one to three days.
- Botox: almost none.
- Lasers: redness for a few days.
A scarf or high collar can cover small bumps on a trip. See low-downtime treatments before flying.
How long do results last?
HIFU and RF results usually last about a year. Boosters last several months after a full course. Botox for neck bands lasts about three to four months. Sunscreen and a good moisturiser help keep results.
Home care for a younger-looking neck
- Apply sunscreen to your neck every day.
- Use your face moisturiser on your neck as well.
- Hold your phone at eye level to reduce bending.
- Consider a retinol product if your skin tolerates it.
Is it safe?
These are common treatments with mostly mild, short side effects. The neck has thin skin and important structures, so energy settings and Botox doses must be chosen carefully. Tell your doctor about any thyroid problems, swallowing issues or recent surgery on the neck.
How to choose a clinic
- Ask which devices or products will be used on the neck and why.
- Ask for a written quote with the number of shots, lines or syringes.
- Make sure the doctor who consults you also performs the treatment.
