Will PDRN Help With Acne? #

If you struggle with acne, acne scars, or the marks left behind after breakouts, you may have heard about PDRN as a regenerative skin treatment.

But will PDRN actually help with acne?

The answer depends on what you mean by “acne.”

PDRN may have potential benefits for skin repair, post-acne marks, texture, and certain acne scars, but it should not be considered a primary treatment for active acne. Current research supporting PDRN and related polynucleotide treatments is stronger for skin regeneration and acne scarring than for directly treating the underlying causes of acne.

At AIVI Aesthetics, we believe it’s important to treat the actual problem rather than simply choosing a treatment because it’s trending.

What Does PDRN Do for Acne-Prone Skin? #

PDRN, or polydeoxyribonucleotide, is a DNA-derived material studied for its regenerative and tissue-repair properties.

Research suggests PDRN may influence pathways involved in skin repair, including adenosine receptor activity and nucleotide synthesis. These mechanisms have contributed to growing interest in PDRN for regenerative dermatology and aesthetic medicine.

For someone with acne-prone skin, the potential value of PDRN may therefore be less about stopping new pimples and more about helping address what acne leaves behind.

1. PDRN May Help With Acne Scars #

This is one of the more interesting potential uses of PDRN and related polynucleotides.

A small randomized controlled study evaluated highly purified polynucleotides in women with moderate-to-severe atrophic acne scars. Patients receiving the polynucleotide treatment experienced significant improvement compared with baseline at one and three months, while the researchers noted that larger studies with longer follow-up are still needed.

More recent research has also explored PDRN as part of combination approaches for acne scars. A 2025 study involving 17 participants found improvement in acne-scar scores with PDRN, with the greatest improvement occurring when PDRN was combined with an intradermal botulinum-toxin technique. The study was small, so these findings should be considered preliminary.

This suggests PDRN may eventually have a useful role in acne-scar treatment plans, particularly when combined with other procedures.

2. PDRN May Support Skin Repair After Acne #

Inflammatory acne can leave the skin looking irritated and uneven even after the active breakout has resolved.

Because PDRN has been studied for its regenerative properties, it may help support the biological processes involved in tissue repair and skin recovery.

This is one reason regenerative treatments are becoming increasingly interesting for patients who have already controlled their acne but still feel that their skin doesn’t look healthy or smooth.

3. PDRN May Help Improve Post-Acne Marks #

After a pimple disappears, you may still be left with a red or dark mark.

These are not necessarily true acne scars.

They may be:

• Post-inflammatory erythema (PIE): red or pink marks
• Post-inflammatory hyperpigmentation (PIH): brown or darker discoloration
• Atrophic scars: indentations caused by loss of tissue

These concerns require different treatment strategies.

A 2026 survey of Korean dermatologists found that polynucleotides were commonly being incorporated into treatment plans for post-acne marks and atrophic acne scars. However, this was a survey of physician practice patterns rather than a controlled trial proving effectiveness.

So while PDRN may have a role in improving overall skin recovery and quality, other treatments may be more appropriate when pigmentation or persistent redness is the primary concern.

4. PDRN May Improve Skin Texture #

Acne can leave the surface of the skin looking uneven long after breakouts stop.

PDRN and polynucleotide treatments have been studied for their potential effects on tissue regeneration and extracellular matrix remodeling.

For mild textural changes, improving overall skin quality may make the complexion appear smoother.

For deeper acne scars, however, PDRN alone may not be enough.

5. What About Enlarged Pores and Oily Skin? #

Acne-prone patients frequently struggle with enlarged pores, excess oil, and uneven texture.

Polynucleotide treatments are being used by some aesthetic physicians for enlarged facial pores, including pores associated with acne, excess sebum, and reduced skin elasticity. A large physician survey reported favorable perceived effectiveness, although these findings reflect clinician experience rather than randomized clinical evidence.

If enlarged pores are your main concern, we would still evaluate why your pores are visible before deciding on treatment.

Collagen loss, oil production, acne scarring, and skin texture can all contribute to the appearance of enlarged pores.

Does PDRN Treat Active Acne? #

This is where an important distinction needs to be made.

PDRN should not currently be considered a first-line treatment for active acne.

Acne is a complex inflammatory condition influenced by factors including excess sebum, follicular plugging, bacteria, inflammation, and sometimes hormonal factors.

Traditional evidence-based acne treatments are designed to target those mechanisms directly.

There is emerging research involving PDRN as part of combination treatment protocols for active acne. For example, a 2026 case report described improvement in severe nodulocystic acne using a multimodal regimen that included isotretinoin, laser treatment, and topical PDRN. Because several treatments were used simultaneously in a single patient, the improvement cannot be attributed to PDRN alone.

More research is needed before PDRN can be considered an established treatment for active acne.

Active Acne vs. Acne Scars: Treat Them Differently #

One of the biggest mistakes patients can make is treating acne and acne scars as though they’re the same problem.

If you still have frequent inflammatory breakouts, the priority is generally to control the active acne first.

Once the acne is controlled, we can focus more aggressively on what it left behind.

That might include:

• Red or brown post-acne marks
• Enlarged pores
• Uneven texture
• Rolling scars
• Boxcar scars
• Ice-pick scars
• Overall loss of skin quality

The treatment plan should be based on the type of scar or mark you actually have.

Is PDRN Enough for Acne Scars? #

Usually, we wouldn’t look at PDRN as the only possible solution for significant acne scarring.

Different types of acne scars respond to different treatments.

Depending on your skin and scar pattern, a comprehensive acne-scar treatment plan may include microneedling, RF microneedling, CO2 laser resurfacing, chemical resurfacing, subcision, regenerative treatments, or a combination approach.

PDRN may potentially complement these treatments by supporting skin quality and regeneration.

The goal isn’t to throw every treatment at the skin. It’s to identify the type of scarring and choose treatments that address it appropriately.

Who May Benefit From PDRN After Acne? #

PDRN may be worth discussing if your acne is relatively well controlled but you’re still concerned about:

• Atrophic acne scars
• Uneven skin texture
• Post-acne marks
• Enlarged-looking pores
• Dehydrated or compromised-looking skin
• Overall skin quality

If you’re still experiencing significant active acne, we would first determine what’s driving those breakouts and whether they need to be controlled before beginning elective scar treatments.

A Skin-Forward Approach to Acne at AIVI Aesthetics #

At AIVI Aesthetics, we don’t believe every patient with acne needs the same treatment.

Someone with active hormonal acne has very different needs from someone who hasn’t had a breakout in years but has rolling acne scars.

That’s why we first look at what you’re actually trying to improve.

If the concern is active acne, we focus on controlling the acne.

If the concern is pigmentation, we address pigmentation.

If the concern is scarring, texture, enlarged pores, or collagen loss, we create a treatment plan around those concerns.

PDRN may be one tool within that plan—but it shouldn’t replace treatments that are better suited to the underlying problem.
