Treatment Overview
Rejuran HB (Hydro Boost) is a specialized polynucleotide (PN/PNN) skin booster from the Rejuran family, combining salmon DNA fragments (PN) with hyaluronic acid (HA). This dual-action formula provides both cellular repair and deep hydration, making it one of the most versatile and popular skin boosters in Korea.
Whereas Rejuran Healer is focused primarily on regeneration, Rejuran HB enhances results by also replenishing moisture, improving elasticity, and delivering the signature Korean “glass skin” glow.
It is part of the PN/PNN booster family (Rejuran Healer, Rejuran i, Rejuran S, Plinest, Juvelook, Plenhyage XL):
- Rejuran HB: Best for hydration + DNA repair.
- Other PN/PNN boosters: Focus on scars, under-eye repair, pigmentation, or deep elasticity correction.
Purpose & Benefits
- DNA Repair & Regeneration: PN/PNN stimulates fibroblasts and strengthens dermal layers.
- Deep Hydration: HA plumps and moisturizes the skin for lasting smoothness.
- Wrinkle Softening: Reduces fine lines and early signs of aging.
- Elasticity Boost: Improves firmness and dermal density.
- Barrier Strengthening: Helps protect fragile or sensitive skin.
- Radiance & Glow: Achieves the luminous “glass skin” look.
- Synergy with Other PN/PNN Boosters: Rejuran HB hydrates while Healer or Plinest work on repair and elasticity.

Rejuran HB in Korea is recommended for:
- Adults in their 20s–60s with dry, dull, or aging skin.

Possible Risks & Complications

- Tightness or Tenderness: May last 1–2 days.
