Quick answer: How many Rejuran sessions do you need? Most people are advised to have a course of about three sessions, spaced two to four weeks apart, followed by maintenance every few months. People with acne scars, very damaged or thin skin may need more sessions, while those wanting a light boost may be happy with one or two. Your doctor will tailor the plan.
Key takeaways
- A typical course is about three sessions.
- Sessions are usually spaced two to four weeks apart.
- Maintenance every three to six months helps keep results.
- Scars and more damaged skin may need more sessions.
- One session can still give visible improvement for visitors.
Why does Rejuran work best as a course?
Rejuran, made by PharmaResearch in Korea, contains polynucleotide (PN) that supports the skin's natural repair processes. Each session gives the skin a fresh boost of support. Repeating treatment at regular intervals allows improvements to build on each other, so texture, fine lines and elasticity improve more clearly than after a single session. This is similar to how many skin treatments work best when repeated.
How far apart should sessions be?
Most doctors recommend spacing Rejuran sessions about two to four weeks apart. This gives the skin time to recover from each treatment and respond before the next one. Shorter or longer intervals may be suggested depending on your skin, the product used and your schedule.
How many sessions for different concerns?
- General skin quality and glow: often about three sessions.
- Fine lines and enlarged pores: usually three, sometimes more.
- Under-eye thin skin (Rejuran i): often two to three sessions.
- Acne scars (Rejuran S): often three or more, sometimes combined with other scar treatments.
- Sensitive or damaged skin barrier: may benefit from a full course and regular maintenance.
Can one session be enough?
Yes, for some people. A single session can make the skin look fresher and more hydrated, which suits visitors with only one chance for treatment. However, for deeper improvements in texture, scars or fine lines, a course usually gives better results. Your doctor can suggest how to get the most from a single session, for example by choosing a suitable dose and combining with home skincare.
How often should you have maintenance?
After the initial course, many people have a maintenance session every three to six months. The interval depends on your age, skin condition and goals. Some people choose a short course of two sessions once or twice a year instead of single maintenance visits.
Does the dose per session matter?
Yes. The amount of product used, often 2cc or more for the full face, affects coverage. A larger face or more concerns may need more product per session. Your doctor will balance dose per session with the number of sessions to fit your goals and travel plans.
Can you combine Rejuran sessions with other treatments?
Yes. Many people combine Rejuran with lifting treatments such as Ultherapy or Thermage, with lasers for pigmentation, or with other skin boosters. Combining treatments may change how many Rejuran sessions you need. Your doctor will plan the order and spacing.
How to plan sessions as a visitor
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Many visitors cannot stay in Seoul for several weeks. Options include having one session per trip, planning trips three to four weeks apart, or having a stronger single session and continuing maintenance on future visits.
Signs your skin is responding
Your skin may feel softer, look more even and hold makeup better. Fine lines and pores may look less obvious over the weeks after each session. Taking photos before your first session and after each one helps you see progress clearly.
