Why the Confusion?
Skin boosters and HA fillers are both injectable aesthetic treatments, and both often contain hyaluronic acid — but their purposes, injection depths, and outcomes are fundamentally different. Knowing the distinction prevents mismatched treatment expectations.
Rappoel Clinic offers complete consultations for both skin boosters (Rejuran PDRN series) and HA fillers (The Chaeum series). Physicians recommend based on each individual’s specific concerns — not a one-size-fits-all approach.
Core Differences at a Glance
| Aspect | Skin Booster (Rejuran) | HA Filler (The Chaeum) |
|---|---|---|
| Primary Purpose | Hydration, skin regeneration, texture improvement | Volume replacement, hollow correction, contour definition |
| Injection Depth | Superficial-to-mid dermis | Deep dermis to subcutaneous fat |
| Technique | Multi-point uniform microinjection (booster gun) | Precise single-point or linear injection |
| Results | Luminosity, hydration, fine line improvement | Hollow filling, contour creation |
| Duration | 3–6 months (multi-session protocol) | 6–18 months (site/volume dependent) |
| Best For | Dullness, dryness, enlarged pores, fine lines | Nasolabial folds, tear troughs, cheek volume, lip shape |
| Can be combined? | ✅ Yes — complementary, can be done in the same visit | |
Skin Boosters — Improving “Skin Quality”
Rappoel’s Rejuran contains PDRN (polydeoxyribonucleotide) — not just hydration, but active stimulation of cellular regeneration and collagen synthesis. Ideal for dull, dry, low-elasticity skin. Post-treatment skin shows significantly improved luminosity and moisture retention.
Choose this if: Your skin itself is the problem — dullness, dryness, fine texture irregularities, decreased bounce — rather than structural volume or contour concerns.
HA Fillers — Solving “Structural Problems”
Used to replace volume lost through fat pad descent and bone resorption, and to reshape proportions (chin projection, cheek volume, nasolabial fold correction). Rappoel uses the high-crosslinkage Chaeum series for extended duration.
Choose this if: You have a specific structural concern — a hollow that needs filling, a contour that needs defining — and your overall skin quality is reasonable.
When You Need Both
Many patients over 30 present with both skin quality decline and structural volume loss. The optimal approach:
- Skin booster first to improve baseline skin quality and moisture retention
- HA filler to address specific hollows and proportion concerns
- Both can be combined in a single visit for maximum synergistic effect
