Before adding volume, give your skin a stronger base. Rejuran is a PN skin booster that aims to create conditions in which thin, rough skin can improve itself.

The Treatment
Repair From Within
———— ✦ ————
Rejuran uses PN (polynucleotide) extracted from salmon DNA fragments. Rather than filling or lifting, it focuses on the environment inside the skin — the barrier, the dermis, firmness and fine lines.
It is particularly helpful for skin that is thin, dries out easily or feels rough, and for skin that needs recovery care after laser treatments. Results are assessed over several sessions rather than expected from a single visit.
BYUS chooses a booster based on your actual skin condition, so Rejuran is recommended when repair is the priority.

Your Session
How Rejuran Is Done
———— ✦ ————
Thin-skinned areas such as under the eyes, and areas with pore or texture concerns such as the cheeks, are common targets. Range and spacing are decided per patient.
- Skin diagnosis — thickness, firmness and texture.
- Anesthesia — topical numbing cream.
- Injection — finely spaced micro-doses across the whole face or target areas.
- Calming — the skin is soothed and the follow-up schedule explained.

How many sessions will I need?
Results are assessed over multiple sessions, with repeat treatment considered every 2–4 weeks. Your plan depends on your skin.
Are there visible bumps afterward?
Small raised bumps, swelling and bruising may last about 1–3 days. Plan important events or photos accordingly.
Can I have Rejuran after a laser treatment?
Rejuran is often used for recovery care after laser treatments. Ask about timing during your consultation.
