Rejuran in Seoul — polynucleotide skin-quality care
A polynucleotide (PN) injectable product family from PharmaResearch. PN is the main material in this product family. It is used for skin-quality concerns rather than as an HA volume gel.
It may be considered for skin quality and fine lines. The product and area must be matched carefully. At Glassy, your dermatologist plans the area, intensity or product around your skin and goals, with comfort considered throughout.
PN is different from hyaluronic-acid filler. Disclose allergies and ask about the exact formulation.
Downtime, aftercare and side effects
Downtime:
Temporary raised injection points, redness, swelling or bruising can occur.
During treatment:
Small pricks or stinging; numbing and other comfort options can be discussed.
Aftercare:
Ask about skincare, exercise and pressure on the treated area before leaving. Follow the instructions for your actual procedure rather than another treatment’s routine.
If you are concerned:
Contact the clinic if symptoms are worsening or do not match the advice you were given.
Who should not have it?
Your dermatologist checks suitability before treatment. Tell us if you:
Have an active infection, broken skin or a new unexplained rash in the area.
Have a known allergy to a proposed product or numbing medicine.
Take medicines, have a medical condition, or have had recent treatment in the same area.
Are pregnant or breastfeeding. Your doctor will discuss whether to postpone the proposed procedure.

Your plan depends on the area, product or device, and any combined care. Ask the clinic for the total before deciding.

Is it a volumizing filler?
Its role differs from a treatment chosen to replace facial volume. If hollowing is your concern, tell the dermatologist first.
How many sessions will I need?
The number of visits and spacing are personalized. We discuss a starting plan and review your response before recommending further treatment.
At Glassy, the starting course follows our Juvelook schedule: at least 3 sessions, 1–3 months apart, adjusted to your skin and response.
Can I combine it with another treatment?
Tell the clinic what you have recently had and what you are planning. Combining procedures is a separate decision; it depends on your skin, the products and the time available for recovery.
Does Rejuran hurt, and can I use numbing cream?
Multiple skin injections can cause stinging or discomfort. Discuss numbing options, allergies and your sensitivity beforehand so your dermatologist can agree a comfort plan; a pain-free experience cannot be guaranteed.
How long can injection bumps, redness or bruising last?
Raised injection points, redness, swelling or bruising can occur, and recovery varies by product, area and delivery method. Tell us about an important event so the team can discuss a suitable recovery buffer.
Rejuran is a PN product family, while Juvelook contains PDLLA and non-crosslinked hyaluronic acid. They are different products rather than interchangeable injections; your dermatologist matches the choice to skin quality, volume and treatment goals.
When should I review results, and how can I plan repeat visits?
Begin assessing skin-quality changes from the second or third session rather than judging temporary fullness immediately after an injection. Glassy generally starts with at least 3 sessions, 1–3 months apart; your skin and travel dates guide review and further treatment.
What allergies or medical information should I mention before Rejuran?
Tell your dermatologist about fish or product allergies, previous injection reactions, medicines, pregnancy or breastfeeding, and active skin problems. The exact formulation and your history must be checked before proceeding.
Is the same Rejuran product used for every area, including around the eyes?
The product family includes different formulations, and delicate areas need their own assessment. Ask which exact product and delivery method are proposed for your area rather than assuming every Rejuran treatment is the same.
