This is Dr. Kim Yeon-jin, director of UHCELL Clinic Gangnam, where we focus on each person&#8217;s own beauty.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As summer winds down, I often hear these in the clinic:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>&#8220;After summer, my skin gets dry and the texture turns rough.&#8221;<\/li>\n\n\n\n<li>&#8220;There&#8217;s no firmness and makeup won&#8217;t sit well.&#8221;<\/li>\n\n\n\n<li>&#8220;My under-eye area especially feels thinner, with more fine lines.&#8221;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The UV and dryness built up over summer lower the skin&#8217;s capacity to regenerate.<br>\nToday I&#8217;ll calmly talk about Rejuran, often discussed as a concept that helps the inner regeneration of summer-worn skin.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/uhcell.com\/wp-content\/uploads\/2026\/06\/UNA00182-1024x683.jpg\" alt=\"\" class=\"wp-image-19955\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">After summer, why does texture turn rough?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Several things overlap in summer skin damage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Strong UV weakens dermal collagen (the protein that supports firmness), while frequent air conditioning, sweat, and washing break down moisture and the barrier together.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As this damage accumulates, the skin&#8217;s own pace of regeneration slows, and you feel the texture turn rough or firmness drop.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>UV lowers collagen and regeneration capacity<\/li>\n\n\n\n<li>Air conditioning and sweat damage moisture and the barrier<\/li>\n\n\n\n<li>As recovery slows, texture and firmness drop<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">So skin that turns rough after summer is often not simple dryness but a state where &#8220;regeneration couldn&#8217;t keep up.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/uhcell.com\/wp-content\/uploads\/2026\/06\/UNA00197-1024x683.jpg\" alt=\"\" class=\"wp-image-19956\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What does Rejuran help with?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Rejuran is used on the idea of delivering PN (polynucleotide, an ingredient derived from salmon DNA) directly into the skin to help the skin&#8217;s own regeneration environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond applying to the surface, it&#8217;s put directly into the skin, looking at areas like texture, firmness, and inner dryness together.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Rejuran Healer: the base line that helps overall texture and regeneration<\/li>\n\n\n\n<li>Rejuran i: a line for the thin, delicate under-eye area<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Since the focus changes with the area and skin state, the key is finding the approach that suits your skin rather than what is &#8220;best.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can home care regenerate skin?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This doesn&#8217;t mean home care is meaningless. The basics are built at home.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Daily UV protection to reduce further damage<\/li>\n\n\n\n<li>Enough moisture to help barrier recovery<\/li>\n\n\n\n<li>Managing sleep and lifestyle to maintain the regeneration environment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Still, there are clear limits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Surface dryness and flakiness may settle to some degree with consistent home care.<br>\nBut an already-lowered regeneration capacity or inner dryness isn&#8217;t easy to fill inside the skin with topicals alone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s exactly why so many people say, &#8220;I apply good products, but the texture stays the same.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/uhcell.com\/wp-content\/uploads\/2026\/06\/UNA00221-1024x683.jpg\" alt=\"\" class=\"wp-image-19957\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How does a clinic approach it?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The core of clinical regeneration care isn&#8217;t &#8220;strong, all at once&#8221; but &#8220;matched to the skin&#8217;s state, in stages.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than finishing Rejuran in one session, it&#8217;s usually done over several sessions a few weeks apart, watching how the skin recovers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is something I want to share honestly.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Change is often observed gradually over several sessions rather than appearing at once<\/li>\n\n\n\n<li>The suitable line and method change with your skin type and area, so it&#8217;s safer to assess your state first<\/li>\n\n\n\n<li>Effects and how long they last vary widely from person to person<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Type<\/th><th>Key point<\/th><\/tr><\/thead><tbody><tr><td>Overall texture &amp; regeneration<\/td><td>Help the regeneration environment with Rejuran Healer and the like<\/td><\/tr><tr><td>Thin under-eye<\/td><td>Approach delicately with Rejuran i and the like, suited to the area<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s why I believe the most important thing in regeneration care isn&#8217;t the product&#8217;s name, but the process of first reading &#8220;where your skin is worn out.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/uhcell.com\/wp-content\/uploads\/2026\/06\/UNA00444-1024x683.jpg\" alt=\"\" class=\"wp-image-19958\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions (FAQ)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How many Rejuran sessions are needed?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It varies with your skin state and area, so it&#8217;s hard to state definitively. It&#8217;s usually done over several sessions a few weeks apart, and the number and interval are best decided after a specialist&#8217;s diagnosis. There is individual variation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What&#8217;s the difference between Rejuran Healer and Rejuran i?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Healer is the base line that helps overall texture and regeneration, while Rejuran i is a line for the thin, delicate under-eye area, so the focus differs. Which line suits you is best decided by looking at your skin state.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can&#8217;t I just use topical cosmetics?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Home care matters as a foundation, but an already-lowered regeneration capacity or inner dryness is hard to fill inside the skin with topicals alone. That said, the need and method vary by individual, so we recommend a consultation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is it okay to get it in summer?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">More important than the season are your skin&#8217;s condition and your schedule. That said, UV protection and moisturizing matter more after a procedure, so it&#8217;s best to consider your lifestyle too. We recommend a specialist consultation.<\/p>\n\n\n\n<div class=\"uh-cta\">\n<p>Worn-out skin changes completely in approach depending on &#8220;why it turned rough and where it&#8217;s worn.&#8221;<br>\nEven when it looks like the same flakiness, for one person reinforced home care is enough, while another needs inner regeneration looked at too.<\/p>\n<p>If you&#8217;re curious which applies to you, a specialist consultation is more accurate than self-diagnosis.<br>\nAt UHCELL Clinic Gangnam, we first examine where and how your skin is worn, then guide you to only what you need right now \u2014 without pushing unnecessary procedures.<\/p>\n<p>If you&#8217;d like a quick skin check while you&#8217;re in Gangnam, Seoul \u2014 or you&#8217;re visiting for travel or business \u2014 please feel free to stop by.
