During winter, skin tends to become flushed and dry. To effectively address this issue through “skin booster” treatments, it’s essential to understand how they work. Due to lower temperatures and dry air in winter, the skin barrier is more vulnerable to damage, making the skin prone to redness, tightness from internal dryness, and buildup of dead skin cells. These problems cannot be adequately resolved with regular moisturizing routines alone. As a result, there’s growing interest in “skin booster” therapies that can transform the skin’s structure to fundamentally improve its condition. A skin booster is a treatment that delivers active ingredients directly into the dermis—going beyond merely temporarily hydrating the skin surface. Instead, it promotes collagen production in the dermis, enhancing the skin’s ability to retain moisture. Applying this treatment during winter, when the skin barrier is weakened, helps restore the skin’s oil-water balance, improving texture, adding luminosity, boosting elasticity, and reducing fine lines. Some well-known skin booster treatments include Leto, Macallan Hiller, Juvelaire, and hyaluronic acid injections. Leto is specifically designed around ECM (extracellular matrix) components that make up the dermis, focusing on delivering collagen and elastin—key elements that support skin structure and facilitate self-repair. Unlike previous skin boosters that primarily emphasized moisturization and collagen stimulation, Leto works by directly replenishing the ECM. Macallan Hiller injects PN, a bio-compatible substance derived from salmon, into the skin to promote regeneration of damaged tissue, helping to reduce fine lines, increase skin elasticity, and improve scars from pores and acne. Juvelaire contains ingredients that stimulate collagen production within the skin, aiming to enhance elasticity and reduce fine lines—especially effective for sagging in the face or around the eyes caused by aging. Lastly, hyaluronic acid injections use hyaluronic acid as their main component to boost moisture retention and refine skin texture. Since different skin booster treatments offer varying benefits for different skin types and issues, it’s crucial to choose the right one based on an individual’s specific skin condition and needs. Lee Jeong-hyun, director of Jryn Hospital in Busan, says, “Winter skin is more sensitive to external stimuli, so care should focus on restoring skin function rather than just achieving aesthetic results. When choosing a skin booster treatment, decisions must be made based on the properties of various ingredients and the patient’s skin condition to achieve optimal outcomes.” He adds, “When undergoing skin booster treatments, it’s advisable not to be swayed by low-price promotions or others’ reviews. Instead, consult a professional doctor first to assess your current skin condition and dermal status before determining the appropriate intensity and type of treatment.” For more details, please visit: >>>> Read the original article at https://mdtoday.co.kr/news/view/1065585453933795

As winter sets in and skin elasticity declines, treatments like Thermage and UltraShape US have gained significant attention. During this cold season, dry air and indoor heating cause rapid loss of moisture from the skin, leading to a noticeable drop in elasticity. When this dryness persists, collagen production in the skin slows down, accelerating the appearance of fine lines and sagging—issues that contribute to premature aging. To address these concerns, many people consider treatments such as Thermage FLX and UltraShape US at the start of the new year to improve their skin condition and appearance. Among the methods available to maintain skin elasticity in winter, Thermage and UltraShape US stand out as popular non-surgical facial lifting therapies. Both are non-invasive and require no skin incisions, making them convenient to incorporate into a busy lifestyle and thus attracting widespread interest. UltraShape US utilizes high-intensity focused ultrasound energy to directly stimulate the SMAS layer deep within the skin, lifting sagging skin and helping to refine the jawline and overall facial contours. The treatment range and energy intensity can be adjusted based on an individual’s degree of skin sagging and elasticity—ranging from 100 to 600 pulses. This personalized approach minimizes unnecessary stimulation while targeting the areas that need improvement. As a result, UltraShape US is particularly suitable for those with sagging jawlines or general facial laxity. In contrast, Thermage delivers heat stimulation throughout the dermis using high-frequency energy, promoting collagen regeneration, improving skin texture, and enhancing overall facial elasticity. This process ensures uniform heat distribution in the dermis, effectively addressing reduced skin elasticity and fine lines. Due to their differing depths of action and mechanisms, more and more people are now opting for combined treatments that leverage the strengths of both Thermage and UltraShape US. By targeting different layers of the skin, this combined approach offers more balanced results in terms of elasticity improvement and anti-aging effects, which has drawn considerable attention. The cost of UltraShape US and Thermage treatments varies depending on factors such as the treatment area, number of sessions, and equipment used. Rather than simply comparing prices, it’s more important to develop a tailored treatment plan based on an individual’s specific skin condition. Especially during winter when skin tends to become more sensitive, a thorough consultation is essential to determine whether these treatments are appropriate for the patient. Lee Jung-hyun, director of Jryn Hospital in Busan’s Somyeon district, says, “In winter, the skin barrier becomes weaker and elasticity drops sharply. It’s crucial to visit a specialized dermatology clinic for a proper evaluation and choose the right lifting treatment based on one’s skin condition.” He adds, “Thermage and UltraShape US each have unique advantages, so patients should consider their skin’s elasticity and degree of aging when selecting a treatment plan.” For more details, please visit: >>> Read the original article at https://mdtoday.co.kr/news/view/1065578316690445

If you’re curious about how the highly sought-after stem cell therapy works for skin regeneration, it’s important to first understand the underlying principles of this process. As aging progresses to a more significant stage, the skin typically experiences reduced elasticity, diminished firmness, the appearance of fine lines, and changes in texture. To address these complex skin issues, stem cell-based treatments have gained increasing attention. However, the effectiveness of stem cell therapy and the necessary follow-up care can vary depending on the application method and components used, so it’s crucial to fully understand these differences before undergoing treatment. The key to stem cell injections lies in creating an environment that promotes skin regeneration. Generally, rather than injecting stem cells directly, growth factors and signaling molecules produced during their cultivation are utilized to stimulate collagen production and tissue regeneration, thereby improving skin elasticity, restoring firmness, and enhancing overall skin health. Recently, in dermatological treatments, stem cell injections are often combined with various regenerative technologies such as exosomes, PRP, MetaCell, and Miracell. Exosomes are substances that facilitate communication between cells and help create an environment conducive to skin regeneration; PRP uses growth factors derived from the patient’s own blood to repair the skin barrier; MetaCell is a stem cell-based injection therapy that triggers skin regeneration by stimulating the dermis and subcutaneous fat layers, helping to improve skin elasticity and tissue condition; while Miracell is a regenerative device that enables more effective delivery of stem cell components to the skin. By increasing cell survival rates and reducing inflammatory responses, it’s used in anti-aging treatments in dermatology. When considering stem cell injection therapy, one shouldn’t just compare the prices of different treatment options but also evaluate whether their components are suitable for one’s specific skin condition. Since everyone’s skin ages differently, it’s essential to comprehensively assess factors such as skin thickness, degree of elasticity loss, and firmness reduction before formulating a treatment plan. Additionally, the benefits of stem cell therapy often become apparent only after some time as the internal skin environment improves, so it’s more important to understand the principles of skin regeneration and the recovery process rather than focusing solely on short-term results. Moreover, consistent proper care in daily life is necessary after stem cell treatment to maintain stable outcomes. Lee Jeong-hyun, director of Jryn Hospital’s Busan West Branch, says, “Skin regeneration therapies such as stem cell injections, exosomes, and PRP all work by promoting collagen production and restoring skin elasticity. Therefore, choosing a treatment plan that suits one’s skin condition and maintaining proper follow-up care are extremely important. Dermatological treatments should not focus merely on improving firmness but should take into account anti-aging effects, texture improvement, and elasticity enhancement, offering personalized treatment approaches.” For more details, please visit the following link: >>>> Original article link: https://mdtoday.co.kr/news/view/1065578831309570

Jryn Hospital’s West Branch Equips with Next-Generation Triple-HIFU Device “Tentriple” Jryn Hospital’s West Branch, led by Director Lee Jeong-hon, recently announced the introduction of the advanced “Tentriple (10TRIPLE)” device based on HIFU technology. Utilizing HIFU, this non-invasive lifting device delivers heat energy to the dermal layer and SMAS layer, thereby promoting the regeneration of collagen and elastic fibers. What sets this device apart is its triple-line, three-point structure, allowing all three transducers to operate simultaneously—resulting in a treatment speed approximately three times faster compared to traditional HIFU devices that use only one line or point per shot. Users can also choose between single-direction and dual-direction scanning modes for flexible adaptation to various clinical scenarios. The device offers seven different types of probe barrels tailored to specific treatment needs: ▲ two types of triple-line barrels (4.5 mm, 3.0 mm) ▲ two types of three-point barrels (4.5 mm, 3.0 mm) ▲ three types of single-point barrels (4.5 mm, 3.0 mm, 1.5 mm), enabling users to select the most suitable option based on the treatment area and skin depth. The triple-line barrels even feature a switchable function between linear and spot modes, allowing for precise adjustments according to treatment requirements. Up to four probe barrels can be installed at once, minimizing downtime caused by barrel changes and ensuring continuous treatment across areas such as the face, neck, and body. The handle is equipped with LED indicators and a temperature sensor, providing users with real-time insights into the device’s operation.

SculpSure/Sculpa, Jryn, Macrogen, Juveline, collagen—these are all skincare products designed to address skin dryness and loss of elasticity. What should you keep in mind when choosing them? The cold winds of winter can leave skin dry and sensitive. Due to seasonal changes and large temperature differences between indoors and outdoors, the skin’s barrier is weakened, making signs of aging such as fine lines more noticeable. However, relying solely on cosmetics to improve existing fine lines, reduced skin elasticity, or dryness doesn’t yield very satisfactory results. If you notice your skin problems worsening ahead of year-end gatherings, social events with friends or family, or other similar occasions, it’s time to consider treatments like SculpSure/Sculpa. These treatments work by delivering active ingredients directly into the dermis to promote collagen production and enhance the skin’s regenerative capacity. For example, Macrogen uses PN components extracted from salmon DNA, which effectively addresses skin dryness, abnormal keratinization, fine lines, and boosts skin elasticity while also helping to restore skin health and soothe it. Macrogen Repairer, on the other hand, utilizes C-PDRN combined with amino acids and hyaluronic acid to repair damaged skin. Compared to traditional Macrogen, its PN molecules are smaller, resulting in higher absorption rates and stronger moisture retention, while also reducing side effects like pain, redness, and irritation. The key to these treatments lies in using microneedles to gently deliver the active ingredients of Macrogen or Macrogen Repairer deep into the skin, ensuring even absorption and sustained effectiveness. Therefore, when selecting such products, not only should you consider the price, but the skill level of the practitioner is equally important. Another product, Juveline, is a collagen supplement made by combining high-molecular PLA with hyaluronic acid. Its advantage lies in its ability to stimulate the skin to produce its own collagen, thereby improving areas where the natural firmness has declined or fine lines are prominent. Juveline is ideal for areas requiring targeted care such as sagging eyelids, fine lines around the eyes and mouth, helping to balance moisture levels, enhance skin elasticity, improve pore appearance and scars, and boost overall skin firmness. There’s also a treatment called SculpSure, which uses PLLA injections to promote collagen production within the skin—making it a non-invasive treatment method. Since PLLA gradually breaks down in the body, it naturally stimulates collagen production over time. The effects of SculpSure aren’t immediate; they become evident over several months as you experience gradual improvement in natural fullness, reduction in fine lines, and enhanced skin elasticity. Recently, in addition to products like Macrogen, Juveline, and SculpSure, there have emerged treatment options using “LITUO” to manage dry skin and alleviate dryness issues. LITUO can fundamentally improve skin elasticity, density, fine lines, and pore condition, and even rebuild the skin structure, which is why users are highly satisfied with it. Lee Jeong-hyun, director of Jryn Hospital in Busan, says, “With the arrival of cold winter winds, many clients ask about the effectiveness of products like Juveline or SculpSure due to dry skin, deeper fine lines, and reduced skin elasticity. To maximize satisfaction from treatments, it’s crucial to first undergo a face consultation to accurately assess your skin condition and understand the differences between Juveline, Macrogen, SculpSure, and LITUO. Additionally, different treatment plans yield varying results, so beyond checking out price discounts for SculpSure or Juveline or reading user experiences with Macrogen and LITUO, it’s essential to fully understand the practitioner’s experience and expertise.” For more details, please visit the following link: >>>> View original article: https://mdtoday.co.kr/news/view/1065576709332356

During seasonal changes, if you’re looking to address skin concerns... the American version of ultrasound lifting can help restore skin elasticity. As temperatures fluctuate dramatically and humidity drops during these transitions, moisture in the skin evaporates rapidly, leading to a noticeable decline in elasticity. The face, being particularly vulnerable to external factors, is especially prone to issues like sagging, deeper nasolabial folds, and double chin when dryness worsens. During this time, collagen levels in the skin decrease, weakening the skin’s structural support, which drives interest in facial lifting treatments that can restore elasticity and combat sagging. Among these, the American version of ultrasound lifting is recognized as a leading dermatological treatment that delivers ultrasound energy deep into the skin to rejuvenate its elasticity. Unlike traditional lifting methods that primarily target the skin’s surface, this technique uses high-intensity focused ultrasound to directly stimulate the SMAS layer—the core layer responsible for skin elasticity. The heat generated by this technology causes proteins in the skin to contract, promoting the production of collagen and elastic fibers during tissue repair, thereby tightening the skin from within. Patients can immediately feel a firmer complexion after treatment, with benefits lasting 2 to 3 months. Most importantly, this procedure requires no incisions or anesthesia, has a fast recovery time, and causes minimal bruising or swelling—making it highly popular among busy modern adults. Not only does it improve overall facial elasticity, but it also naturally lifts away nasolabial folds, double chin, and other signs of sagging. As a result, it’s widely used by people aged 20 to 30 who want to maintain skin elasticity, as well as older adults seeking to reverse signs of aging. However, before deciding on a lifting treatment, don’t focus solely on the cost of the American version of ultrasound lifting. It’s crucial to verify whether the clinic uses proper equipment, whether the practitioners are skilled, and whether the treatment environment is suitable. Poor equipment management or inaccurate energy settings can affect treatment outcomes or even cause thermal damage. To ensure satisfactory results, a thorough assessment of individual factors such as skin thickness, elasticity, and fat distribution is necessary to develop a customized treatment plan. Since different skin conditions require adjusted energy levels or probing depths, these precise adjustments are vital for both safety and effectiveness. Lee Jung-hyun, director of Jryn Hospital in Busan’s western area, says, “During seasonal changes like these, with dry air and large temperature swings, collagen levels in the skin drop rapidly. That’s why facial lifting treatments that restore elasticity from within are extremely beneficial.” He adds, “The American version of ultrasound lifting is particularly effective, as it addresses overall skin elasticity loss, wrinkles, and double chin simultaneously, delivering natural and immediate lifting results.” He also advises, “Before opting for a lifting treatment, don’t just look at the price. Instead, learn about other patients’ experiences and choose practitioners who can tailor the appropriate energy levels and probing depths to your specific skin condition. Additionally, proper daily care such as adequate hydration and UV protection is essential to sustain the results.” For more details, visit: >>>> Read the original article here: https://www.medisobizanews.com/news/articleView.html?idxno=130264
