Ingredient Spotlight: PDRN (Polydeoxyribonucleotide)
If you've spent even five minutes scrolling through Korean skincare TikTok, Olive Young, or beauty influencers' latest routines, chances are you've seen three magical letters everywhere: PDRN.
No, it's not just another trendy skincare buzzword.
Let's dive into everything you need to know.
Meet PDRN: The K-Beauty Ingredient That's Taking Over Your Feed
PDRN is widely recognized as one of K-beauty's leading regenerative skincare ingredients. Originally developed for medical applications to support tissue repair, it has become a sought-after ingredient in Korean skincare thanks to its ability to help maintain the skin barrier, improve hydration, and promote healthier-looking skin. Rather than simply treating surface concerns, PDRN is prized for supporting the skin's natural renewal processes.
Most PDRN used in Korean skincare is derived from purified salmon DNA, specifically from salmon sperm DNA, which is carefully purified and processed. Scientists found that salmon DNA has a high degree of compatibility with human skin, making it useful in regenerative medicine and skincare research. Today, some brands also use biotechnology or plant-derived alternatives that mimic PDRN's skin-conditioning properties, making the ingredient accessible to a wider range of consumers.
Fun fact: Using PDRN skincare doesn't mean you're putting raw salmon on your face. The DNA is highly purified through advanced biotechnology before it's incorporated into skincare formulations.
What Is PDRN?
PDRN (Polydeoxyribonucleotide) is a DNA-derived ingredient originally used in regenerative medicine to help support tissue repair and wound healing.
Traditionally, medical-grade PDRN has been derived from purified salmon DNA because of its high compatibility with human skin. Today, skincare companies also use biotechnology and plant-based alternatives designed to deliver similar skin-conditioning benefits.
In topical skincare, PDRN is commonly formulated to help:
- Improve skin hydration
- Support the skin barrier
- Reduce the appearance of redness
- Improve skin elasticity
- Promote smoother-looking skin
- Enhance post-treatment recovery
Rather than acting as an exfoliant or active acid, PDRN works as a supportive ingredient that helps skin look healthier over time.
Why Is PDRN So Popular in K-Beauty?
K-beauty has always emphasized prevention instead of correction.
Instead of waiting until skin becomes damaged, Korean skincare focuses on maintaining a strong skin barrier, keeping inflammation low, and achieving that famous "glass skin" glow.
PDRN fits perfectly into this philosophy because it pairs beautifully with other hydration heroes like:
- Hyaluronic Acid
- Ceramides
- Peptides
- Niacinamide
- Panthenol
Another reason for its popularity? Many Korean dermatology clinics have used injectable PDRN treatments for years before the ingredient became mainstream in skincare. As consumers became familiar with professional treatments, demand naturally expanded into serums, creams, masks, and even makeup.
Should You Use PDRN in the Morning or Evening?
Morning Routine
Absolutely.
PDRN works well in the morning because it helps keep skin hydrated throughout the day while supporting the skin barrier beneath sunscreen and makeup.
Suggested order:
- Cleanser
- Toner
- PDRN serum
- Moisturizer
- Sunscreen
- Evening Routine
Nighttime is where PDRN really shines.
Since skin naturally undergoes repair while you sleep, many people enjoy pairing PDRN with nourishing creams or overnight masks for extra hydration and recovery.
Evening Routine
- Cleanser
- Toner
- PDRN serum
- Moisturizer
- Sleeping mask (optional)
The good news? PDRN is generally gentle enough to use both morning and night for most skin types.
Korea's Famous PDRN Dermatology Treatment
When people talk about "salmon DNA injections," they're usually referring to PDRN skin booster treatments, with Rejuran being one of Korea's best-known clinic procedures.
Unlike topical skincare, these dermatologist-administered treatments inject PDRN into the skin to support recovery and improve overall skin quality. They're especially popular for addressing dullness, fine lines, acne scars, and post-procedure healing.
Because these are medical procedures, results, downtime, and suitability vary by individual. If you're considering one, consult a qualified dermatologist or licensed medical professional.
Top 5 Best-Selling PDRN Skincare Products in Korea
These products have gained significant popularity through Korean beauty retailers, social media, and Olive Young trends.

Anua PDRN Hyaluronic Capsule 100 Serum
One of the fastest-growing PDRN products in Korea, combining PDRN with hyaluronic acid capsules for deep hydration and skin-plumping benefits. It has become a notable bestseller on Olive Young.

Spotlight on Rejuran: Why This Iconic PDRN Brand Isn't in Our Top 5 (But Still Deserves Your Attention)
If you've been researching PDRN skincare, chances are you've come across Rejuran.
Rejuran is one of Korea's most recognizable names associated with regenerative skincare, thanks to the popularity of REJURAN Healer, the renowned skin rejuvenation treatment offered in Korean dermatology and aesthetic clinics. Building on this reputation, the brand has developed a premium skincare line featuring PDRN-inspired technology designed to support healthy-looking, revitalized skin at home.
So why isn't Rejuran included in our Top 5 Best-Selling PDRN Products?
The answer comes down to how the rankings were determined, not the effectiveness of the products.
Why Rejuran Isn't Included in the Top 5 Ranking
Our Top 5 ranking focuses on consumer retail best-sellers that consistently perform across major Korean beauty retailers (such as Olive Young, Naver Shopping, and Coupang) and international K-beauty platforms.
While Rejuran is highly respected, several factors make it more difficult to compare directly with mass-market retail brands:
- Limited retail distribution: Rejuran products are commonly sold through dermatology clinics, aesthetic clinics, hospitals, specialty beauty retailers, and selected online stores rather than broad retail chains like Olive Young. As a result, they don't consistently appear in public retail bestseller rankings.
- Clinic-first brand positioning: Unlike many K-beauty brands that primarily target everyday consumers, Rejuran first established its reputation through professional aesthetic treatments before expanding into home skincare.
- Multiple hero products: Rather than relying on a single bestseller, Rejuran's skincare range includes several highly regarded products across the Turnover, Radiance, and Pore Care lines. This spreads consumer demand across multiple SKUs instead of concentrating sales on one flagship product.
For these reasons, Rejuran doesn't consistently appear in retail bestseller lists, but that should not be mistaken for a lack of popularity.
Rejuran remains one of Korea's most respected premium regenerative skincare brands, with a loyal following among consumers seeking clinic-inspired skincare. Its association with PDRN technology, skin renewal, and barrier support continues to make it one of the most recognized names in regenerative K-beauty.
