PDRN Creams vs. PN Skin Boosters: The Truth About What Works

From serums and creams to ampoules and sheet masks, PDRN-infused products are everywhere, marketed as the latest must-have in Korean beauty routines. If you’re reading this, chances are you’re wondering: that PDRN cream your friend swears by — can it really match the results of PN (polynucleotide) skin boosters?

PN skin boosters are doctor-administered, injectable treatments recognised for their regenerative and anti-aging benefits. As topical PDRN products become a skincare trend, a common question we get from patients is:

Can PDRN creams really deliver the same results as injectable PN skin boosters?

Polynucleotides: Same Family, Different Science

Both PDRN creams and PN skin boosters belong to the polynucleotide family. Think of polynucleotides as “messengers” for your skin cells: they signal repair, stimulate collagen, and support tissue regeneration.

But here’s the truth: while both are derived from salmon DNA, their differences in molecular structure and delivery methods create distinct effects in the skin:

  • Topical PDRN creams use shorter polynucleotide chains with lower molecular weight, allowing them to penetrate the outer layers of the skin. Their activity is mainly surface-level, supporting hydration, soothing, and barrier repair.

  • By contrast, PN skin boosters consist of longer polynucleotide chains with higher molecular weight and are delivered directly into the dermis via micro-injections. This allows them to provide more binding sites for collagen fibroblasts, allowing deeper skin regeneration.

PDRN Creams vs. PN Skin Boosters Explained

Now that we’ve covered the science, here’s what it means for your skin in real terms — watch Dr. Koh Li-wen explain the key differences and how they affect results.

PDRN (Polydeoxyribonucleotide) Creams

PDRN Creams focus on supporting the surface layers of the skin. Their shorter polynucleotide chains and lower molecular weight allow them to penetrate efficiently into the epidermis, where they help maintain hydration, strengthen the skin barrier, and promote gentle surface-level repair. By nourishing the skin from the outside, PDRN creams prepare it for other treatments, calm irritation, and maintain overall skin health.

They act as a daily support system, enhancing resilience and comfort while promoting ongoing skin maintenance.

Key Benefits of PDRN creams:

  • Hydrate and soothe irritated or sensitive skin

  • Strengthen the skin barrier and maintain healthy skin

  • Reduce redness and support surface-level repair

  • Ideal for daily maintenance and post-procedure care

PN (Polynucleotide) Skin Boosters

PN Skin Boosters, in contrast, work deep within the dermis. Delivered via microinjections, their longer chains and higher molecular weight provide more binding sites for fibroblasts, resulting in sustained nucleotide release and prolonged cellular activation. This deeper mechanism stimulates collagen production, improves elasticity, and enhances overall skin texture.

They are designed for long-lasting rejuvenation to improving skin quality and resilience from within, providing effects that topical creams alone cannot replicate.

Key benefits of PN skin boosters:

  • Stimulate collagen synthesis for firmer, smoother skin

  • Improve elasticity and provide structural support

  • Promote deep dermal regeneration for long-lasting results

  • Enhance overall skin texture and reduce signs of aging

Finding the Right Approach for Your Skin

Choosing the right treatment isn’t just about following trends — it’s about understanding what your skin truly needs. While both PDRN creams and PN skin boosters are derived from salmon DNA, they work in fundamentally different ways and target different layers of the skin.

PDRN creams act on the surface, providing hydration, soothing, and barrier support, whereas PN skin boosters are injected into the dermis to stimulate collagen, improve elasticity, and rebuild the skin’s structure from within. This means that topical PDRN creams cannot replicate the deep regenerative effects of injectable PN skin boosters.

At The Aesthetic Studio Clinic, our doctors can assess your skin and design a personalized treatment plan to ensure you get the right approach for your unique skin needs.

Acne

A commonly overlooked yet physically and psychologically scarring problem, acne is a long-drawn problem that commences at puberty and can drag on well into one’s 20s to 30s. Adult-onset acne is also common, commencing in one’s 20s to 30s and dragging on well beyond that. Caused mainly by accumulation of dead skin, bacterial infection and uncontrolled inflammation, acne is a rather well understood medical condition. Hormonal influences, genetic factors, and even proposed dietary influences are known to be the underlying drivers of acne in some too. Early intervention is the best solution – less acne translates to less scarring, saving you precious time and finances required in attempting to resurface those pesky scars later on.

Acne Treatments

Chemical Peels

Chemical peels consist of mild acids that, when applied to skin, promote controlled exfoliation of skin as well as inactivation of the sebaceous units responsible for breakouts.

Used as a complimentary form of treatment to existing topical therapy, chemical peels can quickly and effectively control most forms of acne.

3-5 sessions are typically required at 2 weekly intervals to bring acne under control, with subsequent sessions done every 4-6 weeks for maintenance.

Carbon Peel

Using a specialised laser and a black carbon-based ink on the face, sebaceous glands can be targeted, bacteria killed, and mild exfoliation performed.

Sessions done at 2-4 weekly intervals can help keep acne bay while also helping to lighten any post-inflammatory pigmentation left by the acne and even reduce pore size.

AGNES

For the larger, stubborn and recurrent acne, the use of a highly selective probe to deliver high radio-frequency energy into the sebaceous unit effectively and permanently inactivates the gland.

This more permanent solution to acne allows for effective management of recurrent acne without having to resort to oral medication such as oral isotretinoin.

Tattoo Removal
Tattoos, while easily placed, are much more complicated to erase. Newer methods of treatment are more reliable, and total time required for tattoo removal can be shortened to less than a year.

Tattoos, while easily placed, are much more complicated to erase. Existing therapies involve the use of nano-second Q-switched lasers, but treatments prove difficult with many requiring 2-3 years of repeated visits at 2-3 monthly intervals. Newer methods of treatment involve the use of newly developed pico-second lasers. These lasers, firing many times faster than conventional Q switched lasers, fracture pigments more effectively. In effect, treatments are more reliable, and total time required for tattoo removal can be shortened to less than a year.

Here at The Aesthetic Studio, we employ the use of the Lutronic Picoplus Pico-second laser for optimal tattoo removal; with 4 wavelengths of light at your disposal, removal of tattoos of varying colour and complexity just got easier.

With a high energy output, a wide range of precisely controllable fluence output and four wavelengths of light for increased versatility, the Picoplus Pico-second laser is optimised for tattoo removal and pigment management. 

Depending on tattoo complexity, 5-10 sessions may be required at monthly intervals for optimal clearance.

Combination with ablative lasers may be advised to reduce post-laser blistering commonly associated with tattoo removal.
