Rejuran Healer results timeline

Rejuran Healer, made by Pharma Research in Korea, uses polynucleotides (PN) derived from salmon DNA. Rather than filling or plumping, PN supports the skin's own repair processes, so results build gradually and improve with each session. Here is what a typical course looks like.

When	What you may notice	What is happening
Day 0	Small raised bumps at injection points; possible pinpoint bruises	PN is placed in the upper dermis
Days 1–3	Bumps flatten; skin may feel slightly tight	The product disperses into the skin
Weeks 1–2	Calmer, more hydrated skin with a soft glow	Repair and hydration processes are supported
Weeks 3–4	Smoother texture; time for the next session	Gradual improvement in skin structure
After 3 sessions	Firmer, more resilient skin; refined pores and softer fine lines	Cumulative improvement in skin quality
Month 6 onward	Gradual return toward baseline	Time for a maintenance session

What improves and what doesn't

Usually improves

Dull, tired or stressed-looking skin
Rough texture and the look of enlarged pores
Fine, crepey lines
Sensitive or easily irritated skin, which often feels calmer
Shallow acne scarring, gradually and over a course

Usually does not change

Volume loss or deep folds
Sagging skin that needs lifting
Pigment spots and melasma on their own
Wrinkles caused by muscle movement

Factors that influence your results

Number of sessions: one session helps, but most of the change comes from a course of about three.
Starting skin: stressed, thin or sensitive skin often shows a more noticeable difference than skin that is already healthy.
Dose and technique: the volume used and how evenly it is placed affect the result.
Age: mature skin can still improve, but may need more sessions.
Daily habits: sun exposure, smoking and harsh skincare work against the result.

How to maximize and maintain your results

Rejuran works well alongside other treatments because it improves skin quality rather than shape. The Glass Skin Package combines it with skin Botox and a soothing LDM session for smoother, brighter skin in one visit. To understand how PN compares with other boosters, read our guide to skin boosters explained or the comparison of Rejuran Healer vs Juvelook.

Skip makeup until the next day and avoid saunas for a day or two.
Use a gentle, fragrance-free moisturizer and daily sunscreen.
Pause strong exfoliants and retinoids for a few days.
Keep sessions on schedule; gaps reduce the cumulative effect.

For what to expect in the first days, see whether there is downtime after skin boosters.

Realistic expectations and when to repeat

Rejuran does not change your features. It makes skin look healthier, smoother and more resilient. If you are visiting Seoul once, a single session is still worthwhile, and you can continue the course on a later trip; see what if you can't finish a treatment series. After the initial course, a session about every six months maintains the benefit. Read our medical team's Rejuran Healer review and check the Rejuran Healer price page. Prices are in Korean won (KRW), exclude 10% VAT, and are confirmed at your consultation.

Tracking your progress

Skin-quality changes are gradual, so close-up photos are more useful than full-face selfies. Take them before your first session and before each later session.

Use the same window light and time of day.
Photograph bare skin, with no makeup or glossy skincare.
Include close-ups of the cheeks and any scarred or textured areas.
Keep the camera at the same distance, with filters off.

If your results aren't what you expected

Judge the course, not a single session. If you have completed three sessions and still see little change, contact Dernia with your photos so your doctor can review them. They may adjust the dose, change the technique or suggest pairing PN with a treatment better suited to your main concern. For other options, browse our results guides.

How long does it take to see Rejuran results?

Many people notice calmer, more hydrated skin within one to two weeks. The fuller change in texture and firmness usually appears after a course of about three sessions.

How many Rejuran sessions do I need?

A course of about three sessions, spaced two to four weeks apart, is common. After that, maintenance about every six months keeps the benefit.

How long do the bumps last after Rejuran?

Small bumps usually flatten within one to three days. Most people can wear makeup the next day.

Is one Rejuran session worth it?

Yes, one session can improve hydration and calmness. The more structural changes, such as smoother texture and firmer skin, build with further sessions.

Can Rejuran help acne scars?

It can gradually improve shallow scarring and texture. Deeper scars usually need a resurfacing treatment such as RF microneedling, sometimes combined with PN.
