Skin Treatments in Your 40s in Cheongdam, Gangnam, Seoul

A face in its forties usually has four findings at once, and the mistake is treating whichever one a website mentioned first. This page is about sequence: which finding to answer before the others, what each step costs at our published rates, and what can safely wait another year.

The Decade

What changes in a face between forty and fifty

Four processes that ran quietly through the thirties become visible in the forties: the supporting layer under the skin loosens, the dermis thins and holds less water, expression lines stop disappearing when the face relaxes, and pigment gathers while facial volume redistributes downward. They arrive together and in different proportions, so a plan for this decade is a priority order more than it is a treatment.

That ordering matters more here than in any other decade. In the thirties one finding usually dominates and one treatment answers it. In the forties four findings compete, budgets are finite, and the sequence you choose decides whether the money buys a visible change or spreads itself too thin to notice.

Everything named on this page is carried out here and published on our rate list. The individual protocols live on their own pages; this one covers the order and the reasoning, then links onward to each of them.

Four Findings

The four things a forties face brings to the consultation room

Naming them separately is the only way to spend a budget in the right order.

FINDING 01

The supporting layer has loosened

The fibrous layer beneath the fat slackens, so the outline that used to hold itself now drifts. It shows first in photographs taken from a three-quarter angle, and it is the finding that energy platforms at depth are built for.

FINDING 02

The dermis is thinner and drier

Collagen density falls and the skin holds less water, which reads as fine crepe texture, dullness and makeup that sits on the surface. This is the finding that injectable boosters and dermal-depth energy address.

FINDING 03

Expression lines have become static

Glabella, forehead and crow's feet lines that once vanished at rest now stay carved. The muscle is the driver here, so this is a toxin finding and a small one to answer.

FINDING 04

Pigment has gathered and volume has moved

Accumulated sun exposure concentrates into patches while the fat compartments of the mid-face thin and sit lower. These are two separate answers: a graded light-based course, and a material that replaces structure.

Hormonal change through this decade affects skin dryness, pigment behaviour and healing speed, and it belongs in the conversation with your own doctor as much as with us. We factor what you tell us into the plan and into how conservatively the first session is dosed.

Diagnosis

How the EVE Muse reading decides which forties finding goes first

EVE Muse captures the face in 3D under five light sources with AI analysis over the result. For a plan in this decade the useful outputs are skin thickness and elasticity, the depth and distribution of pigment, the direction and degree of descent, and how deep the expression lines sit when the face is at rest. Your director ranks those four scores and the highest one opens the plan.
Descent scores highest. Structure comes first, because treating surface quality over a frame that has dropped means paying twice for the same photograph.
Thinning and dryness score highest. An injectable booster course opens the plan and everything structural waits until it has run.
Static lines score highest and skin quality is sound. A small toxin appointment is the whole first step, and it is deliberately modest.
Pigment scores highest. A graded course of low-fluence sessions is started, with sun behaviour discussed at the same visit, because pigment that is still being fed will keep returning.
Two scores tie. The plan runs in sequence with a written interval, never as one long afternoon, so that each step can be judged on its own.

Where the scan reads a face whose four scores are all within range for its age, we do not recommend starting anything, and a sunscreen conversation is the entire outcome of the visit. That happens more often in this decade than people expect.

The Order

The five steps of a forties plan, in the order Dear runs them

Very few faces need all five. The order matters more than the length of the list.

STEP 01

Structure, where descent leads the reading

Imaging-guided focused ultrasound at 1.5, 3.0 and 4.5 mm for the deep layer, or monopolar radiofrequency across a thinned dermis when the finding is surface firmness. Which one is a depth decision taken from the scan, not a preference. See Ultherapy Prime and Thermage FLX.

STEP 02

Skin quality, as a quarterly habit

An injectable booster course for a dermis that has thinned, given in cc units and repeated on a rhythm instead of chased when the skin looks tired. See the Rejuran Healer page and the skin booster category.

STEP 03

Expression lines, dosed small

Botulinum toxin by treated area for lines that have stopped relaxing. In this decade the aim is softening a line while movement is preserved, which is a dose decision made face by face. See the wrinkle botox page.

STEP 04

Volume, only where structure is gone

Hyaluronic acid placed in anatomical layers for a mid-face that has flattened, or collagen-stimulating poly-L-lactic acid by vial where the loss is broad. See cheek filler, the filler category and Sculptra.

STEP 05

Pigment, graded and patient

Low-fluence dual-wavelength toning sessions with skincare, run as a graded course. Pigment work in the forties rewards patience and punishes aggression, and no session here promises an even tone. See the laser toning page.

STEP 00

The step that precedes all five

Daily broad-spectrum sun protection and a settled home routine. Without those, every line above is being asked to outrun something that runs all day. This is free advice and it is the most cost-effective item on the page.

Rates are published in KRW with an approximate USD figure beside them, and visitors pay the same published figures as Korean patients. Toning is also listed as a multi-session course, and the boosters, fillers and lifting platforms each have further sizes; the complete list sits on the published price list, and the lifting platforms are compared side by side on the lifting category page.

Spacing

How one year of forties treatment is actually spaced

Each mechanism has its own clock, and the calendar is built around those clocks.

Structure once, then left alone. Collagen built by focused ultrasound or radiofrequency keeps developing for two to three months, which is when the review sits. Repeating before that review tells you nothing and costs a full session.
Boosters on a rhythm. A booster course is given as a short series and then maintained at intervals set by your skin, closer together where the dermis scored thin and further apart where it did not.
Toxin reviewed, then repeated only if warranted. The change is readable within about two weeks. Whether and when to repeat is a decision taken at review, and a face that is holding well does not need a calendar entry.
Volume judged after swelling, never on the day. Hyaluronic acid is assessed once the initial swelling settles, and collagen-stimulating material works gradually over months, so it is deliberately under-corrected at each visit.
Pigment in a graded course. Sessions are spaced and the parameters adjusted against the response. Pushing a pigment course faster is the reliable way to make pigment worse.

Limits

What a forties plan will not do, stated before you book

The boundaries belong in the diagnosis, and they are short.

It does not reverse the decade. Everything here improves a finding by degrees measured against your own starting photographs. A face that has aged ten years is not returned to the earlier one by any combination on this list.
Marked skin excess is surgical. Where skin can be gathered into a fold that stays put, removing it is an operation and Dear Clinic does not perform facelift surgery. You are told that at the consultation instead of after a course.
Pigment is managed, never declared finished. Sun exposure, heat and hormonal change keep feeding it. A graded course improves what is there and nothing here claims an even tone permanently.
Nothing here lasts indefinitely. Collagen from heat is remodelled again, toxin fades, hyaluronic acid is broken down, and collagen-stimulating material is eventually absorbed. A plan buys an interval and a review date.
Five steps at once is a sales plan. Anyone offered the whole list on a first visit is being sold a package. We sequence, we review, and we stop when the reading says stop.
Dear, Knowhow

Why an age-based plan is written differently at Dear

01 — THE FULL ARSENAL

Every category a forties face needs is on these two floors

Focused ultrasound, several grades of radiofrequency, the booster line, toxin, hyaluronic acid and collagen-stimulating material, and the toning room are all at 5F and 7F. A clinic that owns one of those categories will find a way to recommend it; owning all of them is what makes a sequence recommendation possible.

02 — DIAGNOSIS FIRST

Four scores, ranked before the first booking

Descent, dermis, static lines, pigment. The highest score opens the plan.

03 — DIRECTOR-PERFORMED

The same hands across the whole sequence

A sequence only works if one person remembers what the second step was supposed to answer and what the first one already achieved. Your sessions are director-performed by the doctor who ranked the scores, and the same doctor holds the review at each interval.

Pricing

What a forties plan costs
in Cheongdam, step by step

There is no single figure for a decade, so compare the steps. Expression lines start at ₩30,000 (≈ $20) per treated area at the Korean tier. A booster session is ₩300,000 (≈ $215) for 2cc. Mid-face volume is ₩130,000 (≈ $95) per cc, and the collagen stimulator is ₩1,000,000 (≈ $715) per vial. A toning session with skincare is ₩200,000 (≈ $145). Structure is the largest line: ₩400,000 (≈ $285) per 100-shot block of focused ultrasound, or ₩1,900,000 (≈ $1,355) for a 600-shot radiofrequency tip.

Reading that as a shopping list is the expensive mistake. The steps buy different units of different things, and two of them will matter far more for your face than the other three. A budget that funds one properly sized structural session and one booster course usually outperforms the same money spread across five partial steps, and the ranking from your scan is what decides which two.

Visitors from abroad pay the same published figures as Korean patients, with no surcharge of any kind. Multi-session toning courses and the other booster, filler and platform sizes are listed separately. Consultation and follow-up arrangements are explained at your appointment.

If your four scores sit within range for your age, the recommendation is to wait and to keep wearing sunscreen. That answer is given here more often than the page above might suggest.

Caution

Recovery and risk across the five forties steps

After energy work. Redness settling within hours and a tight, warm feeling for some days. Because these platforms work by heat, a burn is the named risk, and transient numbness or tenderness along the treated band can occur and resolves.
After boosters. Visible injection points, small raised beads that settle over a day or two, and bruising that is common in thinner forties skin. Redness and tenderness at the site are expected in the first evening.
After toxin. Pinpoint bruising and brief redness. Spread beyond the intended muscle can cause temporary asymmetry or a heavy brow, which is dose and placement dependent, so the field is marked before anything is injected.
After filler or collagen stimulator. Swelling, bruising and tenderness for several days. Lumps, nodules and asymmetry are the less common events, and vascular occlusion is the rare serious one that every injector prepares for. Collagen stimulators are massaged and reviewed on a schedule you are given in writing.
After toning. Mild warmth and transient redness, with a real risk of pigment rebound where sessions are pushed too hard or sun exposure follows. Daily sun protection is part of the treatment and not an afterthought.
Call, do not wait. Lasting pain, spreading swelling, blistering, skin that turns pale or dusky, vision change, unresolved numbness or any colour change means contacting the clinic immediately, before the scheduled review.

Tell your director about implanted electronic devices, autoimmune conditions, a history of cold sores, keloid scarring, current medication including blood thinners and isotretinoin, pregnancy and breastfeeding. Several of those change the order of the plan and one or two rule a step out entirely.

FAQ

Skin treatment in your 40s, answered

What should I start with in my 40s if I have never had a treatment?
Start with the scan, then with whichever of the four findings scores highest: descent, dermal thinning, static expression lines or pigment. One properly sized step aimed at the leading finding will show more than three small steps spread across all of them. The other findings are dated into the plan and reviewed before they are treated.
Is Ultherapy Prime or Thermage FLX the right choice at this age?
They work at different depths, so the scan decides. Focused ultrasound at 1.5, 3.0 and 4.5 mm reaches the deep supporting layer and suits descent, at ₩400,000 (≈ $285) per 100-shot block. Monopolar radiofrequency treats the dermis for firmness and texture, sold as a 600-shot tip at ₩1,900,000 (≈ $1,355). Age alone does not choose between them.
How much do skin treatments in your 40s cost in Seoul?
Each step is published separately at Dear Clinic: ₩30,000 (≈ $20) per treated area for expression lines, ₩300,000 (≈ $215) for a 2cc booster session, ₩130,000 (≈ $95) per cc of hyaluronic acid, ₩1,000,000 (≈ $715) per vial of collagen stimulator, ₩200,000 (≈ $145) for a toning session, and ₩400,000 (≈ $285) or ₩1,900,000 (≈ $1,355) for the structural step.
Do I need skin boosters, filler, or both?
They answer different findings. A booster course addresses a dermis that has thinned and dried, working on skin quality across a field. Filler replaces volume where a structure has flattened, placed in anatomical layers. A face can score high on one and normal on the other, which is why the two are ranked separately on the scan instead of sold together.
Will botulinum toxin make my face look frozen in my 40s?
Dose and placement decide that, and in this decade the aim is a softened line with movement preserved. The starting dose is conservative, the result is reviewed at about two weeks, and more can be added at that review. Adding first and regretting later is the sequence we avoid, because a dose cannot be taken back out.
Is it too late to start anti-ageing treatment at 45?
No, and the findings at 45 are usually clearer to read than at 35, which makes the plan more precise. What changes with age is the balance: structural steps carry more weight in the plan and skin quality work is maintained alongside them. Expectations are set against your own starting photographs at every review.
Which treatment helps pigment and melasma-type patches in the 40s?
A graded course of low-fluence dual-wavelength toning with skincare, published at ₩200,000 (≈ $145) per session and also listed as a multi-session course. Pigment in this decade is managed rather than finished: it responds to patient, spaced sessions and it worsens when pushed. Daily sun protection is part of the treatment, and no even-tone outcome is promised.
How long before I see anything, and how long does it last?
Toxin reads at about two weeks. Boosters build over a short series. Collagen-driven change from ultrasound or radiofrequency develops over two to three months, which is when the review sits. Collagen stimulators work gradually over months. We publish no duration figure because it depends on your age, skin thickness, sun history and response; your director gives a conservative expectation and a review date.
Can I have more than one of these in a single visit?
Sometimes, and often it is the wrong idea. Combining two steps in one afternoon makes it impossible to know which one produced the change or which one caused a side effect. Where two findings genuinely tie, the appointments are separated with an interval written into the plan, and the second is confirmed only after the first has been reviewed.
What about menopause and hormonal skin change?
Hormonal change through this decade affects dryness, pigment behaviour and healing speed, and it belongs in the conversation with your own doctor as much as with us. Tell your director what is happening and what you are taking. It changes how conservatively a first session is dosed and how closely a pigment course is spaced.
Who should not start a forties plan here?
Anyone with active infection, inflammation or sunburn in the field waits until it resolves. Implanted electronic devices and metal in the field rule out or change an energy step. Pregnancy and breastfeeding rule out the injection steps. Where skin can be gathered into a fold that stays put, that is surgical territory and we do not treat it here.
I am visiting Seoul for a week. What fits in one trip?
Usually the scan, the consultation and one structural or one skin-quality step, with the rest dated for later and explained in writing. Injectable steps carry a few days of bruising, so the order within a short trip is planned around your flight home. We open weekdays 10:00 to 19:00 and 10:00 to 16:00 at weekends and public holidays — 365 days, with no lunch-hour close.

Scientific Evidence

Science behind the structural and volume steps of a forties plan — peer-reviewed references

The references below cover the two steps of this plan that carry the largest published literature: energy-based tightening and collagen-stimulating volume restoration. Three examine focused ultrasound or radiofrequency for laxity, and three examine injectable poly-L-lactic acid in the ageing face, including one histology study of its biostimulatory activity over time.

Each entry is given as title, journal and year with a verifiable DOI. The booster, toxin and pigment steps have their own literature on their own pages. None of these papers is evidence of a particular outcome for your face, which is assessed at your in-person diagnosis.
