Quick answer: How long do Thermage results last? For many people, Thermage FLX results last about a year, and sometimes up to two years, from a single session. Some tightening is visible soon after treatment, while the main improvement builds over two to six months as collagen renews. Age, skin condition, lifestyle and maintenance all affect how long results last.
Key takeaways
- Thermage results often last about a year, sometimes longer.
- Some immediate tightening appears, with more over two to six months.
- Collagen renewal continues for months after a single session.
- Sun protection and healthy habits help results last longer.
- Many people repeat Thermage once a year for maintenance.
How does Thermage work?
Thermage is a monopolar radiofrequency treatment by Solta Medical. It heats the deep layers of the skin evenly while cooling the surface. This heat causes existing collagen fibres to contract, giving some immediate tightening, and it also stimulates the skin to produce new collagen over the following months. Because collagen renewal is gradual, the results continue to develop long after the treatment day.
When will you see results?
- Right after treatment: some people notice slight tightening and smoother skin.
- Weeks 2 to 4: early swelling settles and skin begins to feel firmer.
- Months 2 to 6: the most noticeable tightening and smoothing appear.
- Up to a year or more: results remain while natural ageing continues.
What affects how long Thermage results last?
- Age: younger skin with more collagen often holds results longer.
- Skin condition: sun damage and very thin skin may shorten results.
- Degree of laxity: mild to moderate laxity responds best.
- Treatment plan: the number of shots and areas treated matter.
- Lifestyle: smoking, heavy sun exposure and poor sleep speed up collagen loss.
- Weight changes: large weight changes can affect skin firmness.
How can you make results last longer?
Daily sunscreen is one of the most effective ways to protect collagen. A good skincare routine with moisturisers and, if suitable, ingredients such as retinoids or vitamin C supports skin quality. Avoiding smoking, sleeping well and keeping a stable weight also help. Many people combine Thermage with skin boosters such as Rejuran to maintain skin quality between sessions.
How often should you repeat Thermage?
Most people repeat Thermage about once a year, depending on their skin and how long their results last. Some with more laxity or older skin may benefit from a slightly shorter interval, while others may wait longer. Your doctor will judge the best timing based on how your skin responds.
Is Thermage FLX longer lasting than older Thermage?
Thermage FLX delivers energy more evenly and treats areas faster, which helps consistency. Many doctors find results comparable to or better than earlier versions, with improved comfort. Individual results still vary.
How does Thermage compare with Ultherapy?
Both often last about a year. Thermage works mainly on skin tightening and texture, while Ultherapy reaches deeper to lift the SMAS layer. Many people combine them, with Ultherapy for lifting and Thermage for tightening, to get broader and longer-lasting improvement.
Which areas can Thermage treat?
Thermage FLX can be used on the face, the eye area, the neck and parts of the body such as the abdomen, arms and thighs. Each area uses a suitable tip and number of shots. Results in thinner areas, such as around the eyes, may look different from those on the lower face or body. Your doctor will explain what to expect for each area you choose.
What results are realistic?
Thermage gives a natural, gradual tightening rather than a dramatic change. Skin often looks smoother, firmer and more refined, and fine lines may soften. It does not replace a surgical facelift for heavy sagging. Clear expectations and a face assessment help you decide whether Thermage alone or a combined plan is right for you.
Planning Thermage around travel
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Many visitors plan Thermage as a yearly treatment during a trip to Seoul. Because downtime is minimal, it fits easily into a short visit, with results continuing to improve after you return home.
