"Skin booster" is one of the fastest-growing search terms in aesthetic medicine, and three names dominate 2026 conversations: Profhilo, Juvelook, and Lenisna. They are not interchangeable — each works on a different layer of the skin and addresses a different problem. Here is the clear-headed comparison Korean dermatologists actually use to choose between them.
What Is a "Skin Booster"?
Skin boosters are injectable treatments that improve skin quality from within — hydration, elasticity, firmness, and glow — rather than adding volume like a filler. They are typically administered in micro-droplets across the face, neck, or hands.
Profhilo: The Hyaluronic Acid Bio-Remodeller
- Active ingredient: Stabilized hybrid hyaluronic acid (32mg high MW + 32mg low MW per syringe)
- Mechanism: Slowly releases HA over ~28 days, stimulating elastin and collagen production
- Best for: Mature skin (35+) with crepiness, dehydration, or mild sagging
- Treatment plan: 2 sessions, 4 weeks apart. Maintenance every 6-9 months
- Cost in Korea: $300 – $500 per session
- Downtime: Minor injection bumps for 24 hours
Juvelook: The PDLLA Collagen Stimulator
- Active ingredient: Poly-D,L-lactic acid (PDLLA) microparticles in HA carrier
- Mechanism: Microparticles trigger gradual neocollagenesis over 3-6 months
- Best for: Lax skin, shallow wrinkles, large pores, post-acne texture
- Treatment plan: 2-3 sessions, 4 weeks apart. Effects last 12-18 months
- Cost in Korea: $400 – $600 per session
- Downtime: Mild redness, occasional micro-papules for 1-3 days
Lenisna: Korea's "Salmon DNA + Polynucleotide" Booster
- Active ingredient: Polynucleotide (PN) of marine origin + tropoelastin
- Mechanism: PN supports cell repair, hydration, and barrier function while tropoelastin restores elasticity
- Best for: Sensitive, thin, post-laser, or rosacea-prone skin; very thin under-eye area
- Treatment plan: 3-4 sessions, 2-3 weeks apart
- Cost in Korea: $350 – $700 per session
- Downtime: Almost none — Lenisna is famously gentle
Side-by-Side Comparison
| Concern | Best Choice |
|---|---|
| Dehydration & dullness | Profhilo |
| Crepey skin & laxity | Profhilo or Juvelook |
| Large pores & rough texture | Juvelook |
| Mild wrinkles & post-acne scars | Juvelook |
| Sensitive, thin, reactive skin | Lenisna |
| Under-eye crepiness | Lenisna |
| Healing post-laser/peel skin | Lenisna |
The Korean "Layered" Approach
Top Seoul dermatologists rarely use these in isolation. A typical 2026 protocol for a 40-year-old international patient might look like this:
- Week 0: Profhilo session 1 (deep hydration + bio-remodelling foundation)
- Week 4: Profhilo session 2 + Juvelook on lower face for tightening
- Week 8: Lenisna under-eye + neck for fine texture
- Maintenance: Single Lenisna or Profhilo touch-up every 4-6 months
Who Should Avoid Skin Boosters?
- Active skin infection or untreated rosacea flare
- Pregnancy or breastfeeding
- Recent (within 2 weeks) laser, peel, or microneedling
- Known hypersensitivity to HA or marine-derived products (for Lenisna)
Frequently Asked Questions
Can I do all three in one trip? Yes. A 7-10 day Seoul trip is enough to receive Profhilo, Juvelook, and Lenisna on different visits, spaced appropriately.
How long until I see results? Hydration shifts within 1-2 weeks. Collagen-driven changes are visible at 6-12 weeks.
Do they hurt? Topical numbing makes the procedure tolerable. Lenisna is the most comfortable; Juvelook the most "ouch."
