EUN PDRN Recovery Serum

EUN PDRN Brightening Serum brings the regenerative technology behind Korea's most sought-after clinic treatment into your daily routine. No appointment, no needles, no downtime.

PDRN (Polydeoxyribonucleotide) is the active ingredient in Rejuran Healer, the injectable skin booster Korean dermatologists have used for over two decades to stimulate collagen, improve skin density, and restore a luminosity that no moisturiser can replicate. We paired it with Acetyl Hexapeptide-8, a signal peptide that communicates directly with collagen-producing cells, and a dual humectant complex of Glycerin and Sodium PCA that mirrors your skin's own natural moisture factors.

The result: skin that looks brighter, feels denser, and holds its hydration well past noon. The kind of glow that makes people ask what you have had done, when the answer is just a serum you use every morning.

What you will notice:

• Fine lines appearing softer and less defined over 4 to 6 weeks of consistent use
• Deeper, longer-lasting hydration that does not need topping up throughout the day
• A more even, luminous skin tone. Less patchy, less dull, more light-reflective
• Skin that feels more substantial. Bouncier, firmer, less tissue-paper thin

The formula: 12 ingredients. No fragrance, no alcohol, no fillers. Suitable for all skin types including sensitive and reactive skin. Lightweight, fast-absorbing, non-greasy. Sits comfortably under moisturiser and SPF.

Pro tip: Apply immediately after home microneedling to significantly boost PDRN absorption and close the gap between topical and clinic results.

Apply 2 to 4 pumps to clean skin. Massage over face and neck until absorbed. Use morning and evening. Follow with moisturiser or SPF.

EUN PDRN Brightening Serum contains 12 ingredients. Every one earns its place. No fragrance, no alcohol, no fillers.

Full ingredient list: Aqua (Water), Glycerin, Propanediol, Panthenol, Sodium Hyaluronate, Sodium PCA, Polydeoxyribonucleotide, Acetyl Hexapeptide-8, Hydroxyethylcellulose, Phenoxyethanol, Ethylhexylglycerin, Sodium Hydroxide.

Apply 2 to 4 pumps to clean, dry skin. Massage gently over your face and neck until fully absorbed. Use morning and evening before your moisturiser or SPF.

For best results, use consistently for at least 4 to 6 weeks. You will feel the hydration and softness within the first few applications. The visible skin quality improvements, including tone, density, and fine line softening, build gradually over time. Do not stop before it gets good.

Yes. The formula was designed with all skin types in mind, including sensitive, reactive, and compromised skin. There is no fragrance, no alcohol, no essential oils, and no known high-irritation actives. PDRN is one of the most well-tolerated ingredients in clinical skincare literature, specifically because it is anti-inflammatory rather than sensitising.

If you are currently in an active flare, dealing with eczema or rosacea, or have recently had a procedure, we still recommend a patch test before applying all over. Apply a small amount to your inner arm or jaw for 24 hours before full use.

This serum is not recommended for use on broken or open skin.

Yes — and this is actually one of the best use cases. Apply retinol/tret first, wait 20 minutes, then layer PDRN. Many people find their recovery from strong actives shortens significantly, and they can use actives more frequently as a result. We've seen this consistently in customer feedback: PDRN doesn't compete with your actives. It manages the consequences.

Most people notice softer, more hydrated skin within the first few days. The real results, the glow, the improved texture, the fine lines looking less defined, come in at the 4 to 6 week mark with consistent twice-daily use.

Week 1: Skin feels softer, more comfortable, more hydrated throughout the day.

Week 2 to 3: Tone starts to even out. Redness settles. Breakouts heal noticeably faster.

Week 4 to 6: The glow that makes people ask what you have been doing. Skin looks denser, brighter, and healthier. Fine lines appear softer.

Week 6 and beyond: Skin that just works. Less reactive, less dry, more resilient. The kind of skin that stops needing constant management.

For faster results, apply immediately after home microneedling. PDRN absorption increases significantly through freshly needled skin and most people report visible changes within 2 to 3 weeks using this method.
