Rejuran Treatment

Rejuran Treatment Of course. Here is a comprehensive overview of Rejuran Treatment, a popular skin-rejuvenation procedure.

What is Rejuran Treatment?

Rejuran is a type of polynucleotide (PN) therapy that involves injecting highly purified and biocompatible fragments of DNA, specifically salmon DNA, into the skin. The “Rejuran” brand is one of the most well-known, originating from South Korea.
The core idea is not to alter your DNA, but to use these DNA fragments as “skin-repairing signals.” These signals stimulate your skin’s own healing processes, boosting collagen production, improving elasticity, and enhancing overall skin health from within.

How Does It Work? The Science Behind It

The polynucleotides in Rejuran work through several key mechanisms:

Cellular Regeneration & Repair: The PN fragments act as a signal to attract fibroblasts (the cells that produce collagen and elastin) to the injection site. They stimulate these cells to produce new, high-quality collagen, which is the fundamental building block of firm, youthful skin.
Anti-Inflammation: Rejuran has notable anti-inflammatory properties, which makes it excellent for calming irritated skin, reducing redness, and improving conditions like acne.
Hydration & Tissue Restoration: Polynucleotides have a remarkable ability to bind with water molecules, providing deep hydration. They also help to restructure the skin’s extracellular matrix, the support system that holds skin cells together.
Improved Blood Circulation: The treatment promotes the formation of new micro-capillaries, enhancing blood flow and nutrient delivery to the skin, resulting in a healthier complexion.

Key Benefits of Rejuran

Improves Skin Texture and Fine Lines: By boosting collagen, it smoothens rough skin and reduces the appearance of fine lines and wrinkles.
Enhances Skin Elasticity and Firmness: It tightens sagging skin, making it particularly popular for areas like the jawline and under the eyes.
Reduces Acne Scars and Enlarged Pores: The regenerative process helps to fill in atrophic acne scars and can make pores appear smaller by plumping the surrounding skin.
Soothes and Calms the Skin: Its anti-inflammatory effect is beneficial for sensitive, red, or acne-prone skin.
Provides Deep Hydration: Results in a dewy, well-hydrated “glass skin” glow.
Strengthens the Skin Barrier: Improves the skin’s overall health and resilience against environmental damage.

The Rejuran Procedure: What to Expect

Consultation: A qualified practitioner will assess your skin concerns and determine if you are a suitable candidate.
Preparation: Your face will be cleansed, and a topical numbing cream is usually applied for about 20-30 minutes to minimize discomfort.
The Injection Process: Using a very fine needle, the practitioner will perform multiple micro-injections into the targeted areas of the skin (e.g., cheeks, forehead, around the eyes, neck). The technique can be a series of small blebs or a deeper, threading technique depending on the concern.
Post-Treatment: The procedure typically takes 30-45 minutes. You might experience mild redness, swelling, or tiny bumps at the injection sites, but these usually subside within a few hours to a day.

Aftercare and Recovery

Immediate Aftercare: Avoid touching, rubbing, or applying makeup for at least 6-8 hours.
Sun Protection: This is crucial. Use a high-SPF, broad-spectrum sunscreen daily, as your skin will be more sensitive to UV damage.
Avoid Heat: For the first 48 hours, avoid saunas, steam rooms, hot showers, and strenuous exercise.
Skincare: Use gentle, hydrating skincare products. Your practitioner will give you specific instructions, which may include avoiding active ingredients like retinoids or AHAs/BHAs for a few days.

Who is a Good Candidate?

Rejuran is ideal for individuals who:

Want to improve overall skin quality, not just address a single line.
Have early signs of aging like loss of elasticity and fine lines.
Struggle with acne scars or enlarged pores.
Have sensitive, red, or dull skin that needs rejuvenation.
Are looking for a “preventative” treatment to maintain youthful skin.
It is not recommended for pregnant or breastfeeding women, people with active skin infections, or those with known allergies to its components.

Results: What to Expect and When

Rejuran is a gradual, regenerative treatment, not a quick filler. Results build over time as your skin produces new collagen.
Initial Glow: You may see improved hydration and a subtle glow within the first few days to a week.
Full Results: The most noticeable improvements in texture, firmness, and scarring are typically seen 4 to 8 weeks after the treatment, once collagen remodeling is well underway.
Longevity: Results can last from 6 to 12 months, depending on your age, skin condition, and lifestyle. A initial series of 3-4 sessions, spaced 4 weeks apart, is often recommended for optimal and longer-lasting results.

Potential Side Effects and Risks

When performed by a trained medical professional, Rejuran is considered very safe. Potential side effects are usually mild and temporary:
Redness, swelling, and bruising at the injection sites.

Small bumps that resolve within a day.

Itching or tenderness.

As with any injection, there is a minimal risk of infection or allergic reaction.

Advanced Topics & Frequently Asked Questions

The Different “Types” of Rejuran: Healer, Finder, etc.
You might hear about different Rejuran products. These are not for different skin types, but for different injection depths and techniques to target specific concerns.
Rejuran I (Healer): This is the classic, most common form. It’s designed for intradermal (middle layer of the skin) injection to improve overall skin texture, elasticity, and scarring. This is the workhorse for full-face rejuvenation.
Rejuran S (Finder): This version is often mixed with a small amount of lidocaine (anesthetic) and is slightly more viscous. It’s used for more superficial injections to target fine lines or for the epidermal-dermal junction to enhance the skin barrier and glow.
Rejuran Body: A formulation designed for larger areas of the body, such as improving the appearance of stretch marks or sagging skin on the abdomen or thighs.
Key Takeaway: A skilled practitioner will choose the right product and, more importantly, the correct injection technique (depth and pattern) for your specific concerns.

The “Downtime” Myth vs. Reality

Social Downtime (Very Low): Significant swelling or bruising is uncommon. Most redness and needle marks fade within a few hours. You can technically go back to work immediately.
Skin Barrier Downtime (Crucial): Your skin has just been micro-traumatized by dozens of needles. Its barrier is temporarily compromised. This is not the time to use harsh actives, go for a run, or skip sunscreen. The “no downtime” refers to social visibility, not the skin’s biological need for gentle care.

The Rejuran “Purge” – Is It Real?

Some patients report a breakout of small pimples a few days to a week after treatment. This is likely not a true “purge” (which is triggered by cell-turnover-increasing ingredients like retinoids).

The more probable causes are:

Reaction to Bacteria: The injections can potentially push surface bacteria deeper into the skin. This is why a clean, sterile technique is vital.
Inflammatory Response: The initial healing process can sometimes manifest as tiny, temporary inflammatory papules.
Product Clogging Pores: While rare, if injected too superficially, the product could contribute to congestion.
This reaction is usually mild and self-resolving. Your practitioner may recommend specific post-care products to manage it.
