Plastic SurgeryThe difference in forehead lift quotes stems from the combination of the surgical procedure (incision/endoscopic/temporal) and anesthesia method (sedation/general). The surgeon's experience, hospital facility rating, and recovery care program determine 30–40% of the cost. The average price range in Korea starts from the 2 million won range, and the price can more than double for complex procedures.
WellnessWhen administering 1g of Vitamin C orally versus 10g intravenously, there is a 25-fold difference in blood concentration; however, the perceived duration of the effect varies from 3 days to 2 weeks depending on the ingredients, dosage, and metabolic rate. Glutathione (GSH) directly reduces intracellular oxidative stress without hepatic first-pass, but due to its half-life of 2–3 hours, changes in skin tone are observed starting 48 hours later. Based on Myers' Cocktail…
Plastic SurgeryDepending on the purpose, ear surgeries are classified into protruding ear correction, ear reconstruction, and earlobe reshaping, with the scope of surgery and recovery period differing by more than twofold for each. The approaches are completely different: protruding ear correction involves cartilage repositioning, ear reconstruction involves rib cartilage grafting, and earlobe reshaping involves fat or filler injection. The domestic guidelines of the Korean Society of Plastic and Reconstructive Surgeons suggest age, degree of deformity, and skin thickness as three primary selection criteria…
Plastic SurgeryThe scope of osteotomy differs between the 3-part facial contouring procedure and orthognathic surgery—the branching point is determined by the presence or absence of occlusal issues. Mini V-line shortens the incision length by 50%, but there are clear limitations for protruding cheekbones or asymmetry of 4mm or more. The 2025 guidelines of the Korean Academy of Maxillofacial Plastic Surgeons suggest 3D CT-based simulation as the primary selection criterion.
SkincareExosomes are nanovesicles, 30–150 nm in size, secreted by cells that induce skin regeneration by directly delivering proteins, mRNA, and growth factors. There are seven types, including stem cell-derived, placenta-derived, and plant-derived forms, and the concentration and duration of growth factors vary by two to three times depending on the cell origin. Because it is a method of cell signal reprogramming rather than simple nutrient supply, laser…
SkincareThe 72 hours after thread insertion is the golden time for collagen rearrangement. Avoiding compression and heat stimulation during this period extends the duration of the results by an average of 3 months. Recovery speeds and re-treatment cycles vary depending on the type of thread: PDO, PLLA, or PCL. The difference in dissolution speed can be up to twofold. The optimal time for re-treatment is when the effect reaches 50%. If re-treatment is performed after the effect has completely disappeared, the initial effect…
SkincareUlthera (HIFU) reaches the SMAS layer to a depth of 4.5mm to induce structural lifting, whereas thread lifting focuses on collagen regeneration centered on the dermis layer (1.5–3.0mm). Thermage (RF) provides a tightening effect by uniformly heating a wide area from the epidermis to the dermis, and pain intensity is in the order of Ulthera > Thread Lifting > Thermage. Prevention in the early 30s…
Plastic SurgeryThe cost of facial contouring surgery varies significantly depending on the combination of surgical sites, the extent of osteotomy, and the method of anesthesia. 3D CT scanning and the fabrication of custom guides account for 15–20% of the total cost and enhance surgical accuracy. While the experience of the medical staff and the rating of the hospital facilities are reflected in the price, a high rating does not necessarily guarantee good results.
ProceduresTeeth whitening is not simply 'applying medicine' — it involves 7 steps from pre-treatment to post-treatment, with each step influencing the result by 20–30%. Systems like Zoom WhiteSpeed and Philips Zoom are FDA-approved for a 25% hydrogen peroxide concentration, while in Korea, products approved by the Ministry of Food and Drug Safety are used within the 15–35% range. Office whitening…
SkincareSkin barrier recovery within 72 hours of the procedure determines the hyaluronic acid retention rate. The re-treatment cycle varies significantly from person to person depending on skin metabolism and lifestyle patterns, ranging from 3 to 6 months. By simply following 5 daily care principles, you can extend the duration of the effects by an average of 6 weeks.
