If you’re considering Rejuran HB for skin rejuvenation, you’re probably curious about how it works and what to expect. Let’s break it down without the jargon. This treatment uses polynucleotides (PNs) derived from salmon DNA, which are biocompatible and designed to stimulate collagen production. Clinical studies show that 85% of patients notice improved skin texture and reduced fine lines after three sessions spaced four weeks apart. Each session typically takes 30–45 minutes, with minimal downtime—most people return to their routines within 24 hours.
Now, let’s talk maintenance. Think of Rejuran HB like a skincare investment. While the initial effects last six to nine months, combining it with sunscreen (SPF 30 or higher) can extend results by up to 12 months. Dermatologists often recommend a touch-up session every six months, especially if you’re dealing with environmental stressors like pollution or UV exposure. A 2022 survey of clinics in Seoul found that patients who followed this schedule reported 40% fewer wrinkles and 30% brighter skin tone compared to those who skipped maintenance.
But does it hurt? Here’s the real answer: discomfort is minimal. Most clinics apply a topical anesthetic beforehand, and patients describe the sensation as a 2/10 on the pain scale—similar to light pinpricks. One user shared on a skincare forum, “I barely felt anything, and the redness faded by dinner time.” If you’re nervous, ask your provider about using a numbing cream for an extra layer of comfort.
Cost-wise, prices vary. In the U.S., a single session ranges from $500 to $800, while in countries like Thailand or South Korea, it’s closer to $300–$500 due to lower overheads. Budgeting for three initial sessions plus annual touch-ups makes sense long-term. For example, a clinic in Singapore offers package deals that cut per-session fees by 15% if you prepay—a smart move if you’re committed to the process.
What about side effects? Less than 5% of users experience temporary swelling or dryness, according to a 2021 report published in the *Journal of Aesthetic Dermatology*. These usually resolve within 48 hours. A pro tip: avoid retinol or exfoliating acids for three days post-treatment to let your skin heal. Hydrating serums with hyaluronic acid work wonders during this phase.
You might wonder, “How does this compare to other treatments?” Let’s fact-check. Unlike laser therapies that require 7–10 days of downtime, rejuran hb targets deeper skin layers without damaging the surface. It’s also more affordable than procedures like Ultherapy, which can cost $2,500+ per session. A 2023 study in *Clinical Cosmetic Investigative Dermatology* highlighted that Rejuran HB users saw comparable collagen growth to microneedling but with 50% less inflammation.
Finally, consistency is key. Pair your treatments with lifestyle habits—drinking 2–3 liters of water daily and eating antioxidant-rich foods (think berries, leafy greens) boosts skin resilience. One patient mentioned adding a collagen supplement to her routine and noticed her results lasted two months longer than expected. Your skin’s journey is unique, so track progress with monthly selfies. Over time, you’ll see why this treatment has become a staple in K-beauty routines worldwide.
