PDRN + Copper: The Skincare Duo That Regenerates Skin From Within

A Korean formula designed for skin that has lost its glow: firmness, deep hydration, and repair, without the complexity.

There are ingredients you see everywhere without really knowing what they do, and then there's PDRN. This salmon DNA derivative, used for years in Korean dermatology for its regenerating properties, has become one of the most sought-after actives right now. Paired with copper peptides, known for boosting collagen production, it forms a duo you rarely find at this concentration in a single bottle.

That's exactly what the Dr. Reju-All Advanced PDRN Copper Peptide Serum (PD2) delivers: a concentrated formula with 1,200 ppm PDRN, enriched with multi-peptides and 1% copper peptides, in a 30 ml bottle.

Why these two actives work so well together

• — PDRN works as a repair signal for the skin: it supports cellular regeneration and helps restore a weakened skin barrier.
• — Copper peptides support the synthesis of collagen and elastin, two key proteins for skin firmness.
• — The multi-peptide complex reinforces the formula's overall firming effect.
• — The lightly blue-tinted gel texture, packed with micro-beads, absorbs quickly without leaving any greasy film.

A regenerating routine doesn't need to be complicated — it needs the right actives, at the right dose.

How to add it to your routine

1. Cleanse your face morning and/or evening with a gentle cleanser.
2. Apply 2 to 3 drops of serum onto clean skin, gently patting until fully absorbed.
3. Let it sink in for one to two minutes before applying a moisturizer to seal in the actives.
4. In the morning, always finish with sun protection (SPF).

Tip: start with evening-only application for a few days to check how your skin tolerates it, before moving to twice-daily use.
