Rejuran is generally considered a well tolerated skin treatment, but it is not risk free. Most reported reactions are temporary and occur around the injection site, including redness, swelling, tenderness, bruising, or small raised bumps. Rejuran Seattle is not suitable for everyone, particularly people with certain allergies, active skin infections, or specific medical conditions, so a qualified medical provider should review health history before any polynucleotide or PDRN treatment is scheduled.

Quick Answer:

Rejuran treatment is broadly regarded as safe when administered by a trained licensed aesthetician trained under the guidance of Board Certified cosmetic surgeons, though side effects are common and typically mild. Serious complications are rare but possible with improper technique. Candidacy depends on individual health history rather than age alone. 

What Is Rejuran?

Rejuran refers to a category of injectable treatments built from purified polynucleotides, intended to support the skin’s natural repair process. It falls under the broader category called skin boosters, distinct from volumizing dermal fillers.

What Is Rejuran Made Of?

Polynucleotides are fragments of DNA sourced from salmon, purified for medical and cosmetic use. PDRN, or polydeoxyribonucleotide, is a related but distinct material, and the two terms are often used interchangeably, which is why the treatment is sometimes called a salmon DNA treatment.

How Does Rejuran Work?

The treatment is believed to support skin repair and may stimulate fibroblast activity, the cells responsible for producing collagen, with proposed effects including improved hydration, texture, and gradual collagen support. The evidence base remains limited: a frequently cited 2014 trial in the Journal of Korean Medical Science was later retracted over undisclosed conflicts of interest and should not be treated as strong safety evidence.

Is Rejuran FDA Approved in the United States?

Injectable Rejuran and related polynucleotide treatments have not received FDA approval for cosmetic injection use in the United States, and approval in South Korea does not transfer to US regulatory standing. Offering a treatment without formal approval does not by itself mean it is unsafe, though it means less centralized oversight than an FDA cleared product.

What Are the Benefits of Rejuran?

Reported benefits center on skin quality, not volume or contour.

• May improve skin texture over a series of sessions.
• May improve skin hydration and moisture retention.
• May soften the look of fine lines.
• May support collagen production through fibroblast stimulation.
• May improve skin elasticity, with results varying by individual.
• May help skin look healthier and more refreshed.
• May help certain texture concerns, including some acne scarring, as part of a broader plan.

What Are the Side Effects of Rejuran?

Side effects are among the most searched questions about this treatment, and most follow a predictable pattern of mild, temporary reactions.

Common Short-Term Side Effects:

• Redness
• Swelling
• Small 
• Raised bumps
• Tenderness
• Bruising
• Mild itching 
• and discomfort at the injection site are most frequently reported. 

A recent study of polynucleotide injections found swelling, pain, and redness common right after treatment, generally mild and temporary.

Less Common Side Effects:

• Prolonged swelling, 
• Persistent inflammation, 
• Infection, 
• Delayed reactions, 
• Allergic responses, 
• Firm lumps or nodules occur less often but have been reported.

Rare but Serious Complications

Serious complications are uncommon but possible, particularly with an unqualified provider or improperly sourced product, and may include infection, granuloma formation, or a severe allergic reaction. An experienced provider substantially reduces these risks.

How Long Do Rejuran Side Effects Last?

Recovery timelines vary by patient and treatment area, and a provider can offer a more specific estimate.

Side effect	Typical course
Redness	Usually short lived
Small bumps	Often settle within a few days
Swelling	Usually temporary
Tenderness	Usually improves quickly
Bruising	May take longer to fade

Who May Be a Good Candidate for Rejuran?

Good candidates are typically concerned about early aging, fine lines, uneven texture, dryness, reduced elasticity, or dull looking skin. Candidacy is determined during an individual assessment rather than by age alone.

Does Rejuran Hurt?

Most patients describe mild discomfort rather than significant pain during the small injections. Topical numbing is often available, and some tenderness afterward is common.

How Is Rejuran Performed?

A typical session includes a consultation, skin assessment, tailored treatment plan, cleansing, numbing when appropriate, and injection of the solution, followed by aftercare instructions and a scheduled follow-up.

Rejuran Recovery and Aftercare

Immediately After getting a Rejuran treatment, there might be:

• Mild redness
• swelling
• tenderness, or small raised bumps 

These might appear around the injection sites immediately after Rejuran treatment. However the reactions are usually temporary and improve as the skin settles. Most patients can return to their normal daily activities the same day, depending on how their skin responds to treatment. The aesthetician will provide proper medical after care treatment advice after getting the treatment. 

What Does Before and After Look Like After Getting a Rejuran Treatment in Seattle?

Rejuran before and after results vary based on skin condition, treatment area, and number of sessions. Unlike fillers, Rejuran focuses on improving skin quality rather than adding volume.

Patients may notice improvements in:

• Skin hydration and texture
• Fine lines
• Skin firmness and elasticity
• Dull or uneven-looking skin
• Certain acne scars

Results develop gradually, and multiple sessions may be recommended based on individual goals. Before-and-after photos show potential results, but outcomes vary from patient to patient.

What to Avoid Afterward Getting a Rejuran Treatment?

Providers typically recommend avoiding excessive heat, strenuous exercise, touching the area, and harsh skincare products, following the provider’s specific guidance.

When Will You See Rejuran Results?

Results are not an instant transformation. Skin changes develop gradually as collagen remodeling takes time, and multiple sessions are often recommended.

How Long Do Rejuran Results Last?

Duration varies by age, skin condition, treatment area, and overall plan, and maintenance sessions are common. No responsible provider should promise a fixed, guaranteed duration.

Rejuran vs. PDRN: What’s the Difference?

Rejuran is a specific branded polynucleotide treatment, while PDRN refers to a related class of purified DNA fragments. The terms are often used interchangeably but are not identical, which matters since a provider may offer a Salmon PDRN treatment rather than the branded Rejuran product.

Rejuran vs. Dermal Fillers

Rejuran focuses on skin quality and produces gradual change, rather than working like a traditional volumizing filler. Dermal fillers restore or add volume and contour specific areas with more immediate visible change, and the two are sometimes combined.

Rejuran vs. Other Skin Treatments

Treatment	Main goal
Rejuran / PN	Skin quality and regeneration
PDRN	Skin repair and quality support
Dermal filler	Volume and contour
Botox	Muscle related wrinkles
Laser resurfacing	Skin resurfacing
Microneedling	Skin remodeling
