Plinest or Rejuran? Ultimate Guide to Choosing the Best Skin Rejuvenation Treatment

Updated: 17 hours ago



Deciding between Plinest and Rejuran for skin rejuvenation? This guide breaks down each treatment, comparing their benefits, procedures, and ideal candidates. Understand key differences in ingredients, target areas, and downtime to determine which treatment best suits your skin goals. We'll also explore combining treatments and potential side effects, helping you make an informed decision.


What is Plinest?

Plinest is a relatively new skin rejuvenation treatment gaining popularity for its ability to improve skin texture, tone, and elasticity. It's a type of injectable known as a "bio-stimulator," meaning it works by stimulating the production of collagen and elastin, the proteins responsible for youthful, firm skin. Unlike traditional dermal fillers that simply "fill" wrinkles or add volume, Plinest works by prompting the body's natural regenerative processes to revitalize the skin from within. This leads to a more natural-looking and longer-lasting improvement in skin quality.


How Plinest Works

Plinest's primary ingredient is Polycaprolactone (PCL), a biocompatible and biodegradable polymer that has been safely used in medical devices for decades. When injected into the dermis, PCL microspheres stimulate fibroblast activity. Fibroblasts are the cells responsible for producing collagen and elastin. This increased production leads to a gradual thickening and tightening of the skin, reducing the appearance of wrinkles, fine lines, and sagging skin. Over time, the PCL microspheres are naturally broken down and eliminated by the body.


PCL Microsphere Size and Concentration

The size and concentration of PCL microspheres in Plinest are crucial for its effectiveness. While specific details may vary depending on the manufacturer, the microspheres are generally microscopic, allowing for smooth and even distribution within the skin. The concentration is carefully calibrated to stimulate optimal collagen and elastin production without causing adverse reactions.


Impact of PCL on Collagen and Elastin Production

The introduction of PCL microspheres triggers a cascade of biological processes that ultimately lead to increased collagen and elastin synthesis. This process, known as neocollagenesis, is the key to Plinest's rejuvenating effects. The new collagen and elastin fibers formed provide structural support to the skin, improving its firmness, elasticity, and overall texture.


Benefits of Plinest

Plinest offers a range of benefits for those seeking skin rejuvenation. Some of the most notable advantages include:

  • Improved skin texture and tone

  • Reduced appearance of wrinkles and fine lines

  • Increased skin firmness and elasticity

  • Natural-looking results

  • Long-lasting effects

  • Gradual and progressive improvement

  • Minimal downtime


Plinest Procedure and Recovery

The Plinest procedure is relatively straightforward. A topical anesthetic is typically applied to the treatment area to minimize discomfort. Then, using a fine needle, the Plinest solution is injected into the dermis. The entire procedure usually takes about 30-60 minutes. Following the treatment, patients may experience some mild redness, swelling, or bruising, which typically resolves within a few days.


Post-Treatment Care

Following the Plinest procedure, it is important to follow your doctor's post-treatment instructions carefully. This may include avoiding strenuous exercise, excessive sun exposure, and certain skincare products for a specified period. Your doctor may also recommend applying ice packs to the treated area to reduce swelling.


What is Rejuran?

Rejuran is a skin rejuvenation treatment originating from South Korea that has gained popularity for its ability to improve skin texture, elasticity, and overall health. It's often referred to as the "baby skin booster" due to its ability to promote healing and regeneration at a cellular level, resulting in smoother, firmer, and more youthful-looking skin.


How Rejuran Works

Rejuran Healer utilizes polynucleotides (PNs), specifically purified deoxyribonucleic acid (DNA) fragments derived from salmon sperm. These PNs are biocompatible with human skin and act as a building block for tissue repair and regeneration. They stimulate fibroblast activity, which are the cells responsible for producing collagen and elastin, the essential proteins that provide skin structure and elasticity. This process helps to strengthen the skin's underlying structure, improve skin tone and texture, reduce the appearance of wrinkles and fine lines, and enhance overall skin health.


The Science Behind Polynucleotides

Polynucleotides are not just fillers; they work on a deeper level by promoting tissue regeneration. This biological process leads to long-lasting improvements in skin quality, rather than just a temporary fix.


Benefits of Polynucleotides
  • Stimulate collagen and elastin production

  • Improve skin hydration

  • Reduce inflammation and redness

  • Promote wound healing


Types of Rejuran

There are different types of Rejuran available, each designed to target specific concerns:

  • Rejuran Healer: Focuses on overall skin revitalization and improving skin texture.

  • Rejuran i: Specifically designed for delicate areas around the eyes to address dark circles and fine lines.

  • Rejuran S: Formulated to treat acne scars and improve skin texture in acne-prone skin.


Benefits of Rejuran

Rejuran offers a wide range of benefits for skin rejuvenation:


  • Improved Skin Elasticity: Rejuran helps restore skin firmness and bounce.

  • Reduced Wrinkles and Fine Lines: By stimulating collagen production, Rejuran helps smooth out wrinkles and fine lines.

  • Enhanced Skin Tone and Texture: Rejuran improves skin smoothness and reduces the appearance of pores.

  • Increased Skin Hydration: Rejuran helps the skin retain moisture, leading to a more hydrated and plump complexion.

  • Reduced Acne Scars and Blemishes: Rejuran can help minimize the appearance of acne scars and improve overall skin texture.


Rejuran Procedure and Recovery

The Rejuran treatment involves a series of microinjections administered directly into the dermis, the middle layer of the skin. A topical anesthetic is usually applied beforehand to minimize discomfort. The procedure typically takes around 30-45 minutes depending on the treatment area.


Post-Treatment Care

Following the treatment, some redness, swelling, and small bumps at the injection sites are common and usually subside within a few days. Patients are advised to avoid strenuous activities, excessive sun exposure, and makeup for 24 hours after the treatment.


Key Differences Between Plinest and Rejuran

Plinest is a newer generation skin booster composed of polynucleotides (PNs) derived from salmon DNA. These PNs are highly purified and biocompatible, minimizing the risk of allergic reactions. The specific concentration of PNs in Plinest can vary depending on the product used, influencing its viscosity and application technique.


Rejuran Composition

Rejuran Healer, on the other hand, utilizes polynucleotides (PNs) sourced from herring sperm DNA. These PNs are also biocompatible and have a slightly different molecular structure compared to those in Plinest. Rejuran is available in different concentrations, each designed to target specific skin concerns and depths.


Comparing PN Sources: Salmon vs. Herring

While both Plinest and Rejuran leverage the regenerative power of polynucleotides, the subtle differences in their source (salmon vs. herring) may influence their efficacy and how they interact with human skin. More research is needed to definitively determine if one source offers superior benefits over the other.


Impact of PN Concentration

The varying concentrations of PNs in both Plinest and Rejuran formulations allow for tailored treatments. Lower concentrations are generally preferred for superficial skin rejuvenation, while higher concentrations are used to address deeper wrinkles and tissue regeneration.
