XERF, Thermage FLX and Ulthera all tighten skin without surgery, but each delivers energy differently. Dr. Park Seong-Soo explains how to choose between them.
Read →Hip dips are not always about weight. In a thin body there may be too little fat to harvest for grafting, so hip filler can be an alternative. Here is how it is planned.
Read →Shape problems surface as swelling settles; inflammation shows up early. A practical checklist for lumps, contour and asymmetry. By Dr. Park Seong-Soo.
Read →One method rarely does both jobs. How combined surgery divides projection from contour, and what the safety check must cover. By Dr. Park Seong-Soo.
Read →They are normal sebaceous glands — about five per breast. Removal targets the gland beneath the bump, not the surface. By Dr. Park Seong-Soo.
Read →Animation deformity shows in a median 58% of submuscular cases. Why athletes plan the plane around the pectoralis, not around size. By Dr. Park Seong-Soo.
Read →Renuvion uses radiofrequency and helium plasma to tighten loose skin under the chin. Dr. Park Seong-Soo explains how it differs from submental liposuction.
Read →Cleavage is set by chest wall width, not by how much fat goes in. What fat can improve in a thin body — and where it stops. By Dr. Park Seong-Soo.
Read →Average hip circumference for Korean women in their twenties is about 91.6 cm (36.1 in). But a number alone does not decide whether you need buttock surgery — here is how it is assessed.
Read →PDO threads are generally absorbed in about 6–8 months and PCL in about 12–18 months. Dr. Park Seong-Soo explains why thread absorption is not the same as how long the lift lasts.
Read →Montgomery tubercles are normal sebaceous glands on the areola, not acne. Dr. Park Seong-Soo explains how to tell them apart and when removal is actually considered.
Read →What can a Basicell skin booster change — texture, hydration, glow, fine lines? Dr. Park Seong-Soo explains what to expect and what needs a different treatment.
Read →Hybrid breast augmentation uses an implant for volume and fat grafting for contour. Dr. Park Seong-Soo explains the division of roles, candidates and recovery.
Read →Asymmetry, implant displacement, fat absorption, infection — what buttock augmentation revision addresses and how the method is chosen. By Dr. Park Seong-Soo.
Read →Breast reduction removes tissue to reduce size and weight, and can reposition the nipple and improve shape. Dr. Park Seong-Soo explains how it differs from a lift.
Read →Red stretch marks respond better than white ones. Dr. Park Seong-Soo explains vascular and fractional lasers, and how needle-free MiraJet delivers drugs into the skin.
Read →Bottoming out is not the same as sagging: the implant descends because the pocket was dissected too low or the inframammary support is weak. By Dr. Park Seong-Soo.
Read →Absorbable threads dissolve over months, yet the lift can remain — because tissue reaction outlasts the thread. Dr. Park Seong-Soo explains the timeline.
Read →About six months is the usual benchmark for breast revision, because swelling settles and tissue stabilises — but infection, haematoma and sudden deformity need assessment immediately. By Dr. Park Seong-Soo.
Read →Buttock fat grafting uses your own fat to restore volume and shape the line from waist to pelvis — and the waist matters as much as the buttock. By Dr. Park Seong-Soo.
Read →Filler breast augmentation adds volume by injection rather than incision — but the ingredient and its approval status for breast enlargement decide safety. By Dr. Park Seong-Soo.
Read →Skin aging is intrinsic aging plus photoaging from UV exposure — which is why the face ages faster than sun-protected skin. Pigment, wrinkles and laxity need different plans. By Dr. Park Seong-Soo.
Read →Inverted nipple correction involves an incision, so no scar is not a claim anyone should make — but grade, duct preservation and recurrence risk decide the method. By Dr. Park Seong-Soo.
Read →Ultrasound focuses heat at a target depth, radiofrequency heats tissue for tightening, and threads pull and fix tissue physically — the choice starts with what is sagging. By Dr. Park Seong-Soo.
Read →Ultrasound, radiofrequency, shockwave and manual therapy each work differently — and energy therapy supports recovery and firmness, not immunity. By Dr. Park Seong-Soo.
Read →Keloid excision alone recurs in nearly 100% of cases — undermining releases tissue beneath the wound edge so the closure is not under tension. By Dr. Park Seong-Soo.
Read →Renuvion2 tightens tissue under the skin with radiofrequency and helium plasma — a different goal from liposuction, and no substitute for excision when skin is truly redundant. By Dr. Park Seong-Soo.
Read →Weight loss shrinks fat, but stretched skin and fibrous support do not shrink at the same rate — which is why tightening and lifting are different goals. By Dr. Park Seong-Soo.
Read →Replacement alone does not fix contracture — the capsule and plane must be addressed too, and most silicone ruptures cause no symptoms. By Dr. Park Seong-Soo.
Read →XERF uses 6.78MHz for superficial heat and 2MHz for deeper tissue — so the plan starts with which layer your concern sits in, not with the shot count. By Dr. Park Seong-Soo.
Read →Gluteal implants add projection where fat grafting cannot, but the plane of insertion changes the complication rate — wound dehiscence was commonest at 10.29%. By Dr. Park Seong-Soo.
Read →Basicell uses autologous fat, autologous blood or donor fat-derived cells — and which cells, from where and how, matters more than the name. By Dr. Park Seong-Soo.
Read →Facial age is not your birth year — it is what skin tone, elasticity, wrinkles, pores and contour add up to. A five-point self-check, with the evidence behind it. By Dr. Park Seong-Soo.
Read →Mirajet uses a 2940nm Er:YAG laser to drive medication into skin as a high-pressure microjet — the device delivers, but the ingredient decides the result. By Dr. Park Seong-Soo.
Read →Thread lift results typically hold six months to a year and a half — but absorption time and lifting time are not the same thing, and design matters more than thread type. By Dr. Park Seong-Soo.
Read →Three skin boosters inject into skin, but their ingredients aim at different things — repair and texture, firmness and lines, or hydration. By Dr. Park Seong-Soo.
Read →A flat hip and a hip dip are different problems. Combining a gluteal implant with fat grafting divides the work — implant for central projection, fat for the lateral line. By Dr. Park Seong-Soo.
Read →Six weeks is the benchmark for real training after augmentation — and pilates and yoga load the chest far more than they look. By Dr. Park Seong-Soo.
Read →HBOT raises oxygen delivered to tissue and may support recovery — but the aesthetic anti-aging evidence is still limited, and adverse events are commoner than in controls. By Dr. Park Seong-Soo.
Read →A flat buttock is a volume problem; a hip dip is lateral hollowing. ADM-based BiVol offers a third route between fat grafting and silicone — with limited long-term data. By Dr. Park Seong-Soo.
Read →Fat, elasticity and redundant skin are three different problems: contraction helps the first two, only excision removes the third. By Dr. Park Seong-Soo.

Read →6.78MHz and 2MHz do different jobs at different depths. What XERF can improve, what it cannot, and why depth matters more than shot count. By Dr. Park Seong-Soo.
Read →BiVol replaces the silicone implant with ADM, a biological matrix. It is not 'nothing inserted', and the long-term volume evidence is still limited. By Dr. Park Seong-Soo.
Read →Anti-aging is not only about a single wrinkle. What regeneration-focused treatment targets, and why the stem-cell evidence is still early. By Dr. Park Seong-Soo.

Read →Retention is the honest measure — around 46% at three years, lower if weight falls. What that means for sizing, harvest and expectations. By Dr. Park Seong-Soo.
Read →A deep fold is a volume and descent problem, not a line to be ironed out. Where threads help, where filler is needed, and what stays. By Dr. Park Seong-Soo.
