Rejuran for Acne Scars: Potential Benefits and Treatment Limitations

Can a skin booster help with acne scars?

Acne scars are one of the most frustrating skin concerns, and many people look for treatments that can soften their appearance without long downtime. Rejuran, a polynucleotide-based skin booster from Korea, is sometimes mentioned in this context. It is important to understand what Rejuran may and may not do for scarring, so you can set realistic expectations and plan with a doctor.

Understanding different types of acne scars

Acne scars are not all the same, and the type of scar strongly affects which treatments may help:

Rolling scars. Broad, gently sloping depressions that give the skin an uneven, wavy look.
Boxcar scars. Wider depressions with sharper edges.
Ice pick scars. Narrow, deep scars that look like small holes.
Post-inflammatory marks. Red or brown discolouration that is not a true change in skin surface.

Scars also change over time. Newer marks that are still red or brown often fade gradually on their own with good sun protection, while older textural scars tend to stay unless treated. Knowing which you have helps the doctor decide whether a skin booster, a laser, microneedling or a combination is the more sensible starting point.

Many people have a mix of these types. A doctor will usually examine your skin under good lighting before suggesting a plan.

Potential benefits of Rejuran for acne scarring

Rejuran is generally used to support skin quality and resilience. In the context of acne scars, doctors may consider it because:

It may support overall texture. Some patients notice skin looks smoother and more even over time.
It is often used alongside other treatments. Rejuran is frequently discussed as part of a plan with laser or microneedling, where it may support skin recovery.
Downtime is relatively short. Temporary bumps and redness usually settle quickly compared with more intensive procedures.
It suits gradual plans. For people who prefer a step-by-step approach, it can be one part of a longer plan.

Some formulas within the Rejuran family are marketed specifically for scarring. Patients can ask during consultation which options are available.

Treatment limitations to keep in mind

It is just as important to understand the limits:

Rejuran alone is unlikely to remove scars. Deep scars, especially ice pick and boxcar types, usually need treatments that work on the skin structure more directly.
Changes are gradual and subtle. Improvement, where it happens, tends to build over a course of sessions.
Results vary. Skin type, scar depth and age of the scars all influence outcomes.
Active acne should be managed first. Treating ongoing breakouts is often the first step before focusing on scars.

How Rejuran may fit into a scar treatment plan

For acne scars, doctors in Korea often combine several approaches over time. At Daybeau Clinic Seomyeon, options on the price list that may be discussed include (first-visit prices, KRW, VAT excluded, 10% VAT added at payment, checked October 2026):

Potenza full face. 99,000 KRW, RF microneedling; the tip is charged separately.
U-Pulse Fraxel. 25,000 KRW, a fractional laser treatment.
Rejuran 2cc. 139,000 KRW, a polynucleotide skin booster.
Exosome 2.5cc. 49,000 KRW, sometimes used to support skin after procedures.

The doctor decides whether to combine treatments, in what order and how far apart. Not every patient needs every option, and a plan may change as your skin responds. You can read more on our acne and scars page and our Potenza page.

Side effects and aftercare

After Rejuran, it is common to have small bumps, redness, mild swelling and possible bruising at injection points. These usually settle within a short period. If Rejuran is combined with laser or microneedling, the downtime will mostly depend on that procedure. Keep the skin clean, avoid picking or squeezing, use gentle skincare and apply sunscreen. If you are prone to pigmentation, are pregnant or breastfeeding, or have an active skin infection, tell the doctor before any treatment.

Frequently asked questions

Can Rejuran fill in deep acne scars?

Rejuran is not a filler and is unlikely to correct deep scars on its own. It is more often used as one part of a broader plan.

How many Rejuran sessions might help with scars?

This varies. Many doctors suggest a course, often combined with other treatments. The doctor will advise after examining your skin.

Should I treat active acne before scars?

Often, yes. Controlling active breakouts is usually an important first step. The doctor can suggest a plan for current acne before focusing on scarring.
