Managing Red and Dry Skin in Winter with Skin Boosters In winter, the low temperatures and dry air can easily weaken the skin barrier, causing the skin to become redder than usual, feel tight due to internal dryness, or develop excess dead skin. Simply focusing on moisturizing is often insufficient to restore healthy skin. As a result, there has been growing interest in "skin booster" treatments that aim to fundamentally improve the structure of the skin. These treatments involve directly injecting effective ingredients into the dermis to enhance the skin's regeneration process. Unlike mere surface moisturizers, skin boosters boost collagen production and water retention in the dermis. During seasons like winter, when the skin barrier is particularly weakened, these treatments can help restore the balance of oils and moisture, leading to improved skin texture, radiance, elasticity, Lifting effects, and reduced wrinkles. Some common types of skin boosters include Lituo, Rejuran Healer, Juvelook, and Hyaluronic Acid injections. Lituo is designed specifically to target the extracellular matrix (ECM) that makes up the dermis. It focuses on delivering components that support skin structure, such as collagen and elastin, thereby helping the skin recover on its own. While other skin boosters primarily focus on moisturization and collagen production, Lituo stands out for its direct replenishment of ECM. Rejuran Healer uses PN, a biocompatible substance derived from salmon, to promote the regeneration of damaged skin tissue. It helps reduce wrinkles, increase skin elasticity, and improve the appearance of pores and acne scars. Juvelook contains ingredients that stimulate collagen production, making it ideal for addressing issues such as decreased skin elasticity and wrinkles. It is also effective at adding volume to areas such as the cheeks and around the eyes that may have lost firmness due to aging. Hyaluronic Acid injections, on the other hand, focus on enhancing skin hydration and smoothing the texture. Each type of skin booster may have different effects depending on an individual's skin type and specific concerns. Therefore, it is important to choose the right treatment based on one's skin condition and needs. Dr. Lee Jeong-heon, founder of Busan's Jryn Clinic, explained, "During winter, the skin is more vulnerable to external stimuli, so it's essential to approach skincare from the perspective of restoring skin function rather than just achieving aesthetic results. When choosing a skin booster, it's crucial to consider the specific properties of the ingredients and the patient's current skin condition to ensure maximum effectiveness." He added, "Rather than being tempted by low-priced promotions or online reviews, it is recommended to consult a professional doctor who can assess your skin’s needs and customize the treatment plan accordingly."

The Reason Why Lifting Treatments Like Ulthrea and Thermage Become So Popular in Winter During winter, the cold and dry air, along with indoor heating, cause the skin to lose moisture rapidly, leading to a noticeable decrease in elasticity. Prolonged dryness can accelerate the breakdown of collagen, causing fine lines and sagging, which can exacerbate aging concerns. To address these issues, many people are seeking minimally invasive lifting treatments such as Ulthrea and Thermage FLX at the beginning of the new year, aiming to improve their skin’s condition and appearance while reducing discomfort. Two of the most popular facial lifting treatments in winter are Ulthrea and Thermage. Both are non-surgical procedures that enhance skin elasticity without incisions, making them convenient for busy individuals. Ulthrea uses high-intensity focused ultrasound to target the SMAS layer deep within the skin, lifting sagging areas and improving facial contours. The number of treatments and intensity can be customized based on individual skin conditions, allowing for targeted rejuvenation while minimizing unnecessary stimulation. Ulthrea is particularly effective for those with sagging jawlines or overall facial droop. Thermage, on the other hand, utilizes radiofrequency energy to generate thermal stimulation throughout the dermis, promoting collagen regeneration and improving skin texture and overall elasticity. This even heat distribution helps to reduce sagging and smooth out fine lines. Since the two treatments act on different layers of the skin, combining them can provide more balanced results, offering better anti-aging benefits. When considering the cost of Ulthrea and Thermage treatments, it’s important to consider factors such as the treatment area, the number of sessions, and the type of equipment used. Rather than simply comparing prices, it’s better to develop a treatment plan that suits one’s specific skin needs. During winter, when the skin is more sensitive, it’s essential to receive thorough consultations to ensure that the chosen treatment is appropriate for one’s condition. Dr. Lee Jeong-heon, the founding director of Jryn’s Busan Seomyeon branch, emphasized the importance of professional dermatological advice during winter. “During this season, the skin’s barrier becomes weaker, and elasticity declines significantly. It’s crucial to visit a specialized dermatology clinic for a precise assessment and to choose a lifting treatment that matches your individual skin needs.” He also noted that since Ulthrea and Thermage have different mechanisms of action, it’s best to tailor the treatment based on one’s specific skin concerns and signs of aging.

If you are considering stem cell treatments for skin regeneration, it’s essential to understand the underlying principles of this process. As aging progresses, it often leads to a decrease in skin elasticity, volume, as well as the appearance of fine lines and changes in skin texture. To address these multifaceted skin changes, interest in stem cell-based skin treatments has been growing. However, the effectiveness and management of these treatments can vary depending on the method of application and the components used, so it’s crucial to have a thorough understanding before undergoing any procedure. The core of stem cell injections is creating an environment that promotes skin regeneration. Typically, rather than directly injecting stem cells themselves, growth factors and signaling molecules produced during the stem cell culture process are used to stimulate collagen production and tissue regeneration. This approach aims to improve skin elasticity, restore volume, and enhance overall skin condition, helping to achieve a more youthful appearance. In recent years, dermatological treatments have increasingly combined stem cell injections with various other regenerative therapies, such as Asce+ Exosomes, PRP (Platelet-Rich Plasma), MetaCell, and MiraCell. Asce+ Exosomes help facilitate cell-to-cell communication, thereby supporting the creation of a favorable skin regeneration environment. PRP uses growth factors derived from the patient’s own blood to promote the repair of the skin barrier. MetaCell is a stem cell-based injection that stimulates the dermis and subcutaneous fat layers, promoting skin regeneration and enhancing elasticity and tissue recovery. MiraCell is a device that allows for more efficient delivery of stem cell-derived components to the skin, improving cell survival rates and reducing inflammatory responses, making it useful for anti-aging treatments. When considering stem cell injection treatments, it’s not enough to simply compare prices; you should also consider the treatment composition and whether it is suitable for your specific skin condition. Since the manifestations of skin aging vary from person to person, it’s important to conduct a comprehensive analysis of factors such as skin thickness, the degree of elasticity loss, and the extent of volume reduction before planning a treatment plan. Moreover, the effects of stem cell treatments often become apparent over time as the skin’s internal environment improves. Therefore, it’s more beneficial to understand the principles of skin regeneration and the recovery process rather than focusing solely on short-term results. Proper maintenance after treatment is also essential for maintaining stable and long-lasting benefits. Dr. Lee Jeong-heon, President of Jryn’s Busan Seomyeon Branch, stated, “Skin regeneration treatments such as stem cell injections, Asce+ Exosomes, and PRP work by promoting collagen production and restoring skin elasticity. Therefore, choosing the right treatment based on your skin condition and ensuring proper post-treatment care are crucial. Dermatological treatments should go beyond merely improving volume; they should also address aging, skin texture, and elasticity through a personalized approach.” For more information, please visit: >>>View the original article here: https://mdtoday.co.kr/news/view/1065578831309570

Skin Boosters: Helping to Combat Deep Dryness and Loss of Skin Elasticity… What You Need to Know The cold winds of winter can leave our skin dry and sensitive. During this season, the large temperature differences between indoors and outdoors, as well as between day and night, can weaken the skin’s barrier, making wrinkles and other signs of aging more noticeable. However, relying solely on skincare products is often insufficient to address deeply ingrained skin issues such as wrinkles, reduced elasticity, or dryness in combination areas. If you’re facing these skin concerns before upcoming events like year-end reunions or family gatherings, consider undergoing a skin booster treatment. Skin boosters are minimally invasive procedures that deliver active ingredients directly into the dermis, promoting collagen production and enhancing the skin’s regenerative capacity. For example, “Rejuran” uses PN (polynucleotides) derived from salmon DNA to address dryness, roughness, wrinkles, improve skin elasticity, and soothe the skin. “Rejuran Healer,” on the other hand, combines C-PDRN with amino acids and hyaluronic acid to repair damaged skin. Its smaller particle size ensures better absorption and longer-lasting hydration, while minimizing pain, redness, and irritation. The key to achieving optimal results lies in the skillful application of these ingredients using microneedles, so it’s important to consider both the cost of the treatment and the expertise of the practitioner. “Juvelook” is another type of collagen booster that combines high-molecular PLA with hyaluronic acid to stimulate the production of natural collagen in areas where volume has diminished or wrinkles are prominent. It can be used to treat fine lines around the eyes, mouth, and nose, helping to balance moisture levels, improve skin elasticity and reduce wrinkles, as well as enhance skin volume. “Sculptra” is a non-invasive treatment that uses PLLA to promote collagen production within the skin. PLLA gradually breaks down in the body, naturally stimulating collagen production over time. The effects of Sculptra are gradual, with visible improvements in skin volume, deep wrinkles, and elasticity appearing over several months. Recently, treatments like Rejuran, Juvelook, and Sculptra have been complemented by “Lituo,” a product designed to manage dryness in combination areas and improve skin texture. Lituo effectively enhances skin elasticity, density, reduces wrinkles, and tightens pores, helping to rebuild the skin’s structure and deliver high satisfaction. Dr. Lee Jeong-heon, founder of Jryn Clinic’s Busan Seomyeon branch, noted, “As winter approaches, we’re seeing an increase in inquiries from customers concerned about dryness in combination areas, deep wrinkles, and loss of skin elasticity. To ensure satisfactory results, it’s essential to undergo a thorough consultation to understand your skin’s specific needs and compare the benefits of different skin boosters.” He also emphasized the importance of considering the practitioner’s experience and expertise, as well as any available discounts or reviews.

For those struggling with skin issues during the seasonal transition... "Ulthrea Lifting" can help restore skin elasticity. During this period of increased temperature fluctuations and lower humidity, the moisture in our skin evaporates rapidly, leading to noticeable loss of elasticity. The face, being the most exposed area to the external environment, is particularly affected, making it easy to develop sagging, Nasolabial Fold Correction, and a weakened jawline. At this time, the reduction in collagen within the skin weakens its support structure, increasing interest in facial lifting treatments to rejuvenate elasticity and tighten loose skin. Among these methods, Ulthrea stands out as a leading dermatological lifting procedure that delivers ultrasonic energy deep into the skin to restore its firmness. While traditional lifting treatments mainly target the surface of the skin, Ulthrea uses high-intensity focused ultrasound (HIFU) technology to directly stimulate the SMAS layer—the key layer responsible for skin elasticity. The heat generated during this process causes proteins in the skin to contract and promotes the production of collagen and elastin, thereby fundamentally strengthening the skin. Immediately after the treatment, patients experience a noticeable tightening effect, which continues to improve over the following 2 to 3 months. Moreover, Ulthrea is a non-invasive procedure with no need for incisions or anesthesia, allowing for quick recovery with minimal bruising or swelling—making it especially popular among busy modern individuals. It not only improves overall facial elasticity but also effectively targets areas such as the Nasolabial Fold Correction, Double Chin, and skin sagging, making it suitable for people in their 20s and 30s looking to maintain their youthful appearance as well as middle-aged and older individuals seeking to reduce signs of aging. However, before opting for a lifting treatment, it is important to consider more than just the cost of Ulthrea. Factors such as the use of genuine equipment, the expertise of the medical staff, and the overall quality of the treatment environment should all be evaluated carefully. Poor equipment maintenance or inaccurate energy settings can diminish the effectiveness of the treatment or even cause thermal damage to the skin. To ensure maximum satisfaction with the results, it is essential to undergo a thorough assessment of one’s skin thickness, elasticity, and fat distribution before developing a personalized treatment plan. The energy level and depth of the treatment will vary depending on these factors, so precise adjustments are crucial for ensuring safety and optimal results. Dr. Lee Jeong-heon, founder of Jryn Clinic in Seomyeon, Busan, explained, "During seasons like this, the dry air and large temperature differences cause collagen to decline rapidly in the skin. Therefore, treatments that target the deeper layers of the skin to restore elasticity are very helpful. Ulthrea, in particular, can effectively address overall facial sagging, wrinkles, and a weakened jawline, providing both natural and immediate results." He added, "Before choosing a lifting treatment, it is important to consider various reviews and to select a medical professional who can determine the right energy level and treatment depth based on your specific skin condition. Additionally, proper post-treatment care, such as maintaining adequate hydration and protecting the skin from UV rays, is essential for long-lasting results."
