ABOUT THE TREATMENT
Rejuran is known as a regenerative skin therapy that delivers bio-compatible polynucleotides (PN) into the skin. These DNA fragments—sourced from wild salmon—stimulate collagen, improve skin structure, and restore skin health at the cellular level.

Your Treatment Journey
Step 1
Consultation
An in‑person assessment with Dr. Teh or her team to discuss your skin concerns, suitability, and explain the Rejuran treatment process, including risks and alternatives.
Step 2
Treatment Plan
If suitable, a personalised plan is created — outlining target areas, expected number of sessions, and realistic outcomes based on your goals.
Step 3
The Session
Rejuran is delivered via micro‑injections of polynucleotides (PN) to stimulate collagen and repair skin. Treatment typically lasts ~30–60 minutes per area. Mild redness may occur but settles quickly.
Step 4
The Review
Dr. Teh’s team will follow up to review your progress, assess improvements in texture and elasticity, and discuss whether further sessions are recommended.
Suitable For
Treatment Experience
During the Session
Rejuran is delivered via micro‑injections of polynucleotides (PN). Patients may feel mild pinpricks or slight pressure as the solution is placed into the skin. The procedure is generally well‑tolerated, with numbing cream applied beforehand for comfort.
After Your Session
Most patients resume normal activities immediately. Mild redness, pinpoint marks, or slight swelling may occur but typically resolve within 24–48 hours. Makeup can usually be applied the next day.
Timeframes
Results develop gradually as collagen and elastin rebuild. Improvements in texture, hydration, and elasticity appear over 2–4 weeks, with optimal outcomes after a series of sessions. Dr. Teh will discuss realistic timelines tailored to your skin goals during consultation.

Your Treating Doctor
Dr. Teh has over 20 years of clinical experience in non-surgical cosmetic medicine. Every Rejuran treatment plan at Dermedica begins with an in-person assessment to determine suitability and design a plan specific to you.
Treatment Cost
The cost of Rejuran depends on the number of areas treated, the size of each area, and the number of sessions recommended for your individual goals. Dr. Teh will provide an accurate, itemised quote following your consultation.
Rejuran is made from polynucleotides (PN) extracted from salmon DNA. These molecules are known for their biocompatibility and ability to support skin repair, reduce inflammation, and naturally stimulate collagen production.
Rejuran is effective for addressing fine lines, acne scars, enlarged pores, uneven texture, redness, and sensitivity. It is also commonly used to support skin recovery after laser treatments.
Some clients notice visible improvement after 1–2 sessions, but optimal results typically develop after 3–4 treatments as collagen gradually regenerates over time.
Rejuran is administered via micro‑injections. A numbing cream is applied to reduce discomfort, and most clients experience only mild swelling or redness that resolves within 1–2 days.
Unlike fillers that add volume, Rejuran heals the skin from within by stimulating natural collagen production. It improves skin texture, elasticity, and tone without altering facial contours.
At Dermedica Perth, Rejuran treatments are performed by Dr Joanna Teh, a trusted cosmetic doctor with over 20 years of experience. Her gentle, personalised technique delivers natural‑looking, long‑lasting results to clients across Karrinyup, Scarborough, and wider Perth.
