| Main difference | Skin boosters refine the surface; collagen boosters strengthen the structure of the skin. |
| How Doje uses them | Skin boosters in Hydration & Soothing and Pores & Texture care; collagen boosters as options in the Mid-Face, Marionette and Jawline programs. |

Two families, often confused
“Booster” is used loosely in Korean clinics, which is why so many visitors ask whether a skin booster and a collagen booster are the same thing. They overlap, but their main goals differ.
Skin boosters (스킨부스터) aim at quality: hydration, smoothness, glow, fine lines and how well the skin recovers. At Doje this group includes Rejuran (a polynucleotide, PN, booster), Re2O, and exosome-based care. Rejuran is added selectively in Hydration & Soothing care; exosome is commonly delivered with Potenza in Pores & Texture care.
Collagen boosters aim at structure: firmness and density, especially in thin or slackening skin. At Doje, Radiesse (calcium hydroxylapatite) and GOURI (PCL-based) appear as options in the Mid-Face, Marionette and Jawline programs. Their effect builds gradually over weeks to months.
How Doje Clinic decides
Doje’s philosophy — “care needs change as time passes” — applies directly here. In your 20s and early 30s, the skin often needs quality and recovery; later, density and support become more important. In a 1:1 consultation Dr. Byun Jeik reviews skin thickness, elasticity, dryness and sensitivity, and a Mark-View 3D analysis can quantify texture and pores.
- Dull, dehydrated or reactive skin; fine texture issues — skin booster.
- Thinning, crepey or loosening skin — collagen booster.
- Delicate eye area — specific options such as Eye Rejuran or Re2O Fine.
- After lifting or energy treatment — a skin booster can support recovery and finish.

Skin booster vs collagen booster side by side
| Skin booster | Collagen booster | |
|---|---|---|
| Examples at Doje | Rejuran, Re2O, exosome, autologous exosome | Radiesse, GOURI |
| Mechanism | Supports hydration, repair and surface quality | Stimulates collagen for density and firmness |
| Depth / target | Superficial dermis; surface quality | Dermis or deeper planes across a zone |
| Suits | Dullness, dryness, texture, recovery | Thin or lax skin, loss of firmness |
| Sessions | Usually a short series; varies | Often one to a few; varies |
| Downtime | Small bumps or marks, typically settle in days | Mild swelling or bruising, typically days |
| Onset | Often noticed within weeks | Gradual over weeks to months |
When Doje combines them
The pairing “GOURI/Re2O” in Doje’s programs is a practical example: GOURI where density is needed, Re2O where surface refinement matters. Similarly, Radiesse may support the lower face while Rejuran improves skin quality on the cheeks. Combining is considered only when both deficits are present; otherwise one well-chosen product is preferred.
Which should you choose?
- Skin booster if your skin is mainly dry, dull, sensitive or rough.
- Collagen booster if your skin feels thinner and less firm than before.
- Both if you notice changes in quality and firmness together.
- Neither alone if contour loss or sagging is the main issue — filler or lifting is likely needed.

Booster plans are quoted after a 1:1 consultation, as product and number of sessions vary. Korean non-covered (비급여) aesthetic fees are set per plan; ask for a written quote.

Frequently asked questions
Is Rejuran a collagen booster?
Rejuran is usually grouped as a skin booster. It is a polynucleotide product used for skin quality and recovery rather than primarily for firmness.
Is GOURI a skin booster?
GOURI is a PCL-based collagen-stimulating injectable. It is used mainly for density and firmness, often paired with Re2O for surface quality.
Which is better for my 20s?
Younger skin more often needs quality and hydration, so skin boosters are a common starting point. Your actual plan depends on assessment.
How many sessions are needed?
Skin boosters are usually a short series; collagen boosters vary. Dr. Byun suggests a schedule after your consultation.
Can I combine boosters with a thread lift?
Yes. Boosters are often added to lifting plans to improve the skin over the lifted structure.
Will boosters change my face shape?
They are not designed to change contour. Shape changes come from filler or lifting.
